Feedback To The Driver
The instrument cluster has an HDC icon and the HDC
switch has an indicator light, which offers feedback to the
driver about the state HDC is in.
The cluster icon and switch indicator light will illumi
-
nate and remain on solid when HDC is enabled or acti
-
vated. This is the normal operating condition for HDC.
The cluster icon and switch indicator light will flash for
several seconds then extinguish when the driver pushes
the HDC switch but enable conditions are not met.
The cluster icon and switch indicator light will flash for
several seconds then extinguish when HDC disables
due to excess speed.
The cluster icon and switch indicator light will flash
when HDC deactivates due to overheated brakes. The
flashing will stop and HDC will activate again once the
brakes have cooled sufficiently.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases
the brake while stopped on an incline, HSA will continue to
hold the brake pressure for a short period. If the driver
does not apply the throttle before this time expires, the
system will release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for HSA to
activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed. (If the doors are
attached, then the door must be closed. If the doors
are detached then the driver's seat belt must be
buckled.)
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK or NEUTRAL. For vehicles equipped with a
manual transmission, if the clutch is pressed, HSA will
remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
page 184 for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet conditions.
It will periodically apply a small amount of brake pressure
to remove any water buildup on the front brake rotors. It
functions when the windshield wipers are in LO or HI
speed. When RBS is active, there is no notification to the
driver and no driver interaction is required.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while pull
-
ing a trailer. HSA is not a substitute for active driving
involvement. It is always the driver’s responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road con
-
ditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.
WARNING!
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
the brake pedal.
HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK (P).
Failure to follow these warnings can result in a colli
-
sion or serious personal injury.

SAFETY
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates when
an emergency braking situation may occur by monitoring
how fast the throttle is released by the driver. The
Electronic Brake Controller (EBC) will prepare the brake
system for a panic stop.
Selec-Speed Control (SSC) — If Equipped
SSC is intended for off-road driving in 4WD Low
only. SSC maintains vehicle speed by actively
controlling engine torque and brakes.
SSC has three states:
1. Off (feature is not enabled and will not activate)
2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application)
3. Active (feature is enabled and actively controlling
vehicle speed)
Enabling SSC
SSC is enabled by pushing the SSC switch, but the
following conditions must also be met to enable SSC:
The driveline is in 4WD Low.
The vehicle speed is below 5 mph (8 km/h).
The parking brake is released.
The driver door is closed (If doors are attached, the
door must be closed. If doors are detached, the driver
seat belt must be buckled).
The driver is not applying throttle.
Activating SSC
Once SSC is enabled it will activate automatically once the
following conditions are met:
The driver releases the throttle.
The driver releases the brake.
The driver seat belt is buckled.
The transmission is in any selection other than PARK.
Your vehicle speed is below 20 mph (32 km/h).
The driver door is closed. (If doors are attached, the
door must be closed. If doors are detached, the driver
seat belt must be buckled).
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade and
the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
1st = 0.6 mph (1 km/h)
2nd = 1.2 mph (2 km/h)
3rd = 1.8 mph (3 km/h)
4th = 2.5 mph (4 km/h)
5th = 3.1 mph (5 km/h)
6th = 3.7 mph (6 km/h)
7th = 4.3 mph (7 km/h)
8th = 5 mph (8 km/h)
9th = 5.6 mph (9 km/h) — if equipped
REVERSE = 0.6 mph (1 km/h)
NEUTRAL = 1.2 mph (2 km/h)
PARK = SSC remains enabled but not active
SSC Target Set Speeds — If Equipped With Off Road+
1st = 0.6 mph (1 km/h)
2nd = 0.9 mph (1.5 km/h)
3rd = 1.2 mph (2 km/h)
4th = 1.5 mph (2.5 km/h)
5th = 1.8 mph (3 km/h)
6th = 2.5 mph (4 km/h)
7th = 3.7 mph (6 km/h)
8th = 5 mph (8 km/h)
REVERSE = 0.6 mph (1 km/h)
NEUTRAL = 1.2 mph (2 km/h)
PARK = SSC remains enabled but not active
NOTE:
During SSC, the +/- gear selector input is used for SSC
target speed selection but will not affect the gear
chosen by the transmission. While actively controlling
SSC, the transmission will shift appropriately for the
driver-selected set speed and corresponding driving
conditions.
SSC operation is influenced by Off Road+ drive mode if
active. The differences may be notable to the driver as
a varying level of aggressiveness.
Driver Override
The driver may override SSC activation with throttle or
brake application at any time.
SAFETY
251
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
The driver overrides SSC set speed with throttle or
brake application.
The vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h).
The vehicle is shifted into PARK.
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
The driver pushes the SSC switch.
The driveline is shifted out of the 4WD Low.
The parking brake is applied.
The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
The vehicle is driven greater than 40 mph (64 km/h).
SSC will exist immediately.
The driver door opens. (Driver door opens if doors are
attached or driver seat belt is unbuckled if doors are
detached).
Feedback To The Driver
The instrument cluster has an SSC icon and the SSC
switch has a lamp that offers feedback to the driver about
the state SSC is in.
The cluster icon and switch lamp will illuminate and
remain on solid when SSC is enabled or activated.
These are the normal operating conditions for SSC.
The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enabled conditions are not met.
The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
The cluster icon and switch lamp will flash then extin
-
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” or
“Full Off” modes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off-road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

E
QUIPPED
The BSM system uses two radar sensors, located inside
the taillights, to detect highway licensable vehicles
(automobiles, trucks, motorcycles, etc.) that enter the
blind spot zones from the rear/front/side of the vehicle.
Rear Detection Zones
When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear and enters standby mode when the vehicle is
in PARK (P).
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rearview mirror and extends
approximately 10 ft (3 m) beyond the rear fascia/bumper
of the vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
The BSM system DOES NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones.
The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and
trailer before making a lane change. If the trailer or
other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in the
BSM Warning Light remaining illuminated the entire
time the vehicle is in a forward gear
The Blind Spot Monitoring (BSM) system may experi
-
ence dropouts (blinking on and off) of the side mirror
warning indicator light when a motorcycle or any small
object remains at the side of the vehicle for extended
periods of time (more than a couple of seconds).
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If blockage is detected,
a “Blind Spot Temporarily Unavailable, Wipe Rear
Corners” message will display in the cluster, both mirror
lights will illuminate, and BSM and RCP alerts will not
occur. This is normal operation. The system will
automatically recover and resume function when the
condition clears. To minimize system blockage, do not
block the area of the rear fascia/bumper where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.) and keep it clear of road
contaminations.
BSM Radar Location (Left Side Shown)
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM Warning Light
located in the outside mirrors in addition to sounding an
SAFETY
253
Warning Light Location
The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to see
if an alert is necessary. The BSM system will issue an alert
during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from either
side of the vehicle.
Side Monitoring
Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection zone with a relative
speed of less than 30 mph (48 km/h).
Rear Monitoring
Overtaking Traffic
If you pass another vehicle slowly with a relative speed
less than 15 mph (24 km/h) and the vehicle remains in
the blind spot for approximately 1.5 seconds, the warning
light will be illuminated. If the difference in speed between
the two vehicles is greater than 15 mph (24 km/h), the
warning light will not illuminate.
Overtaking/Approaching
Overtaking/Passing
The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, etc. However, occasionally the system may alert on
such objects. This is normal operation and your vehicle
does not require service.
6
254
SAFETY
The BSM system will not alert you of objects that are
traveling in the opposite direction of the vehicle in
Opposing Traffic
Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out of
parking spaces where their vision of oncoming vehicles
may be blocked. Proceed slowly and cautiously out of the
parking space until the rear end of the vehicle is exposed.
The RCP system will then have a clear view of the cross
traffic and if an oncoming vehicle is detected, alert the
driver.
RCP Detection Zones
RCP monitors the rear detection zones on both sides of
the vehicle, for objects that are moving toward the side of
the vehicle with a minimum speed of approximately 3 mph
(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
When RCP is on and the vehicle is in REVERSE, the driver
is alerted using both the visual and audible alarms,
including reducing the radio volume.
NOTE:
In a parking lot situation, oncoming vehicles can be
blocked by vehicles parked on either side. If the sensors
are blocked by other structures or vehicles, the system will
not be able to alert the driver.
Blind Spot Modes
Blind Spot has three selectable modes of operation that
are available in the Uconnect system.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM system
will provide a visual alert in the appropriate side view
mirror based on a detected object. However, when the
system is operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and audible alerts
when a detected object is present. Whenever an audible
alert is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the
appropriate side view mirror based on a detected object.
If the turn signal is then activated, and it corresponds to
an alert present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn signal and
detected object are present on the same side at the same
WARNING!
The Blind Spot Monitoring system is only an aid to help
detect objects in the blind spot zones. The BSM system
is not designed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors, glance
over your shoulder, and use your turn signal before
changing lanes. Failure to do so can result in serious
injury or death.
WARNING!
Rear Cross Path Detection (RCP) is not a backup aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using
RCP. Always check carefully behind your vehicle, look
behind you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and blind spots
before backing up. Failure to do so can result in serious
injury or death.

time, both the visual and audible alerts will be issued. In
addition to the audible alert the radio (if on) will also be
muted.
NOTE:
Whenever an audible alert is requested by the BSM
system, the radio is also muted.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio
is also muted. Turn/hazard signal status is ignored; the
RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be no visual
or audible alerts from either the BSM or RCP systems.
NOTE:
The BSM system will store the current operating mode
when the vehicle is shut off. Each time the vehicle is
started the previously stored mode will be recalled and
used.
Door Removal
When either the front driver or passenger door is removed,
the instrument cluster will display “Blind Spot Temporarily
Unavailable” and the BSM system will disable. While the
system will continue to indicate whatever blind spot mode
it was previously in within the Uconnect system, no visual
or audible alerts will be provided. As long as the doors are
removed, the instrument cluster will provide the “Blind
Spot Temporarily Unavailable” pop-up as a reminder that
the system is disabled every time the ignition is cycled.
Upon re-installation of both doors, the system will resume
functionality based on the personalized mode selected.

QUIPPED
The FCW with Mitigation system provides the driver with
audible warnings, visual warnings (within the instrument
cluster display), and may apply a haptic warning in the
form of a brake jerk, to warn the driver when it detects a
potential frontal collision. The warnings are intended to
provide the driver with enough time to react, avoid or
mitigate the potential collision.
NOTE:
FCW monitors the information from the forward looking
sensors as well as Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings as
well as a possible haptic warning in the form of a brake
jerk.
If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver reacts
to the warnings by braking and the system determines
that the driver intends to avoid the collision by braking but
has not applied sufficient brake force, the system will
compensate and provide additional brake force as
required.
If a FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum
braking possible to mitigate the potential forward
collision. If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will hold
the vehicle at standstill for two seconds and then release
the brakes.
FCW Message
When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
NOTE:
The minimum speed for FCW activation is 3 mph
(5 km/h).
The FCW alerts may be triggered on objects other than
vehicles such as guardrails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within a key cycle, the Active Braking portion of FCW will
be deactivated until the next key cycle.
6
256
SAFETY
The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings.
FCW may not react to irrelevant objects such as over
-
head objects, ground reflections, objects not in the
path of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
FCW will be disabled like ACC, with the unavailable
screens.
Turning FCW On Or Off
The FCW setting menu can be adjusted through the
To turn the FCW system on, select between “Only
Warning” and “Warning and Braking” in the FCW menu.
Select “OFF” in the FCW menu to turn the FCW system
off.
NOTE:
When the FCW is “on”, this allows the system to warn
the driver of a possible collision with the vehicle in
front.
When the FCW is “off”, this prevents the system from
warning the driver of a possible collision with the
vehicle in front. If the FCW is set to “off”, “FCW OFF” will
be displayed in the instrument cluster display.
When FCW status is set to “Only Warning”, this
prevents the system from providing limited active
braking, or additional brake support if the driver is not
braking adequately in the event of a potential frontal
collision.
When FCW status is set to “Warning and Braking”, this
allows the system to warn the driver of a possible colli
-
sion with the vehicle in front using audible/visual warn
-
ings and it applies autonomous braking.
The system will retain the last setting selected by the
driver after ignition shutdown.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Far
When the sensitivity of FCW is set to the “Far”
setting, this allows the system to warn the driver of
a possible more distant collision with the vehicle
in front using audible/visual warnings.
More cautious drivers that do not mind frequent
warnings may prefer this setting.
NOTE:
The “Far” setting may result in a greater number of FCW
possible collision warnings experienced.
Medium
When the sensitivity of FCW is set to the “Medium”
setting, this allows the system to warn the driver of
a possible collision with the vehicle in front using
audible/visual warnings.
Near
When the sensitivity of FCW is set to the “Near”
setting, this allows the system to warn the driver of
a possible closer collision with the vehicle in front
using audible/visual warnings.
This setting provides less reaction time than the
“Far” and “Medium” settings, which allows for a
more dynamic driving experience.
More dynamic or aggressive drivers that want to
avoid frequent warnings may prefer this setting.
NOTE:
The “Near” setting may result in a lesser number of FCW
possible collision warnings experienced.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW Limited
Functionality” or “ACC/FCW Limited Functionality Clean
Front Windshield” momentarily, there may be a condition
that limits FCW functionality. Although the vehicle is still
drivable under normal conditions, the active braking may
not be fully available. Once the condition that limited the
system performance is no longer present, the system will
return to its full performance state. If the problem persists,
see an authorized dealer.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. In rare situations, the system
may react to surrounding objects such as tunnels,
bridges, guardrails, etc. The driver has the responsibility
to avoid a collision by controlling the vehicle via braking,
steering, and acceleration. Unintended braking
reactions can always be overridden by pressing down
hard on the accelerator. Failure to follow this warning
could lead to serious injury or death.
SAFETY
257
Service FCW Warning
If the system turns off, and the instrument cluster
displays:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.

YSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
NOTE:
The alert warning on the cluster will stay on until the tire is
inflated to the placard pressure.
The tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature decreases, the
tire pressure will decrease. Tire pressure should always be
set based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also increase
as the vehicle is driven. This is normal and there should be
no adjustment for this increased pressure.
See
page 345 on how to properly inflate the vehicle’s
tires.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(Tire Pressure Monitoring System Warning Light)
illuminates, you must increase the tire pressure to the
recommended cold placard pressure in order for the
TPMS Warning Light to turn off.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn on the
TPMS Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold placard
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
CAUTION!
The TPMS has been optimized for the original equip
-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip
-
ment that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on after
-
market wheels, and may contribute to a poor overall
system performance. Customers are encouraged to
use Original Equipment Manufacturer (OEM) wheels
to ensure TPMS feature operation.
Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealer to have your sensor function
checked.
After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois
-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
6
258
SAFETY
NOTE:
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire failure
or condition.
The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure, unless your vehicle
is equipped with a Tire Fill Alert or Selectable Tire Fill
Alert feature.
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla
-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire mainte
-
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
Seasonal temperature changes will affect tire pres
-
sure, and the TPMS will monitor the actual tire pres
-
sure in the tire.
System Operation
The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
Tire Pressure Monitoring System Display
NOTE:
It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
Tire Pressure Monitoring System Warning Light
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. In addition, the
instrument cluster will display a "Tire Low" message for a
minimum of five seconds, an "Inflate to XX" message and
a graphic showing the pressure values of each tire with the
low tire pressure values in a different color.
Tire Pressure Monitoring System Low Pressure Warning
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those in a different
color in the instrument cluster graphic) to the vehicle’s
recommended cold placard pressure value as shown in
the "Inflate to XX" message. Once the system receives the
updated tire pressures, the system will automatically
update, the pressure values in the graphic display in the
instrument cluster will return to their original color, and
the TPMS Warning Light will turn off.
SAFETY
259
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
SERVICE TPMS WARNING
When a system fault is detected, the TPMS Warning Light
will flash on and off for 75 seconds and then remain on
solid. The system fault will also sound a chime. In addition,
the instrument cluster will display a "SERVICE TIRE
PRESSURE SYSTEM" message for a minimum of five
seconds and then display dashes (--) in place of the
pressure value to indicate which sensor is not being
received.
If the ignition is cycled, this sequence will repeat, providing
the system fault still exists. If the system fault no longer
exists, the TPMS Warning Light will no longer flash, and
the “SERVICE TIRE PRESSURE SYSTEM” message will no
longer display, and a pressure value will display in place of
the dashes. A system fault can occur due to any of the
following:
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors
Installing some form of aftermarket window tinting that
affects radio wave signals
Lots of snow or ice around the wheels or wheel hous
-
ings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS sensors
Vehicles With A Full-Size Matching Spare
1. If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a Tire Pressure
Monitoring System sensor, and can be monitored by
the Tire Pressure Monitoring System (TPMS) when
swapped with a low pressure road tire.
2. In the event that the matching full-size spare tire is
swapped with a low pressure road tire, the next
ignition switch cycle will still show the TPMS Warning
Light to be on, a chime to sound, an Inflate to XX
message to appear in the instrument cluster, and the
graphic display will still show the low tire pressure
value in a different color.
3. Driving the vehicle for up to 20 minutes above
15 mph (24 km/h) will turn off the TPMS Warning
Light as long as none of road tires are below the low
pressure warning threshold.
TPMS DEACTIVATION — IF EQUIPPED
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such as when
installing winter wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring System sensors. Then, drive the
vehicle for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will flash on and
off for 75 seconds and then remain on. The instrument
cluster will display the “SERVICE TIRE PRESSURE
SYSTEM” message and then display dashes (--) in place of
the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TIRE PRESSURE
SYSTEM” message in the instrument cluster but dashes
(--) will remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TIRE PRESSURE SYSTEM” message and then display
pressure values in place of the dashes. On the next
ignition cycle the "SERVICE TIRE PRESSURE SYSTEM"
message will no longer be displayed as long as no system
fault exists.
TIRE FILL ALERT
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature in the customer settings menu of the
Uconnect system.
NOTE:
Only one tire can be filled at a time when using the Tire
Fill Alert system.
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the system is
in deactivation mode (if equipped).
6
260
SAFETY
The system will be activated when the system detects an
increase in tire pressure while filling the tire. The ignition
must be in the ON/RUN mode with the transmission in
PARK for vehicles equipped with an automatic
transmission. For vehicles equipped with a manual
transmission, the parking brake must be applied.
NOTE:
It is not required to have the engine running to enter Tire
Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode. If the hazard lamps do not come on
while inflating the tire, the Tire Pressure Monitoring
System sensor may be in an inoperative position,
preventing the TPMS sensor signal from being received. In
this case, the vehicle may need to be moved slightly
forward or backward.
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
The horn will chirp once to let the user know when to
stop filling the tire, when it reaches recommended
pressure.
The horn will chirp three times if the tire is overfilled
and will continue to chirp every five seconds if the user
continues to inflate the tire.
The horn will chirp once again when enough air is let
out to reach proper inflation level.
The horn will also chirp three times if the tire is then
underinflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
NOTE:
The Tire Fill Alert feature is set to “Disabled” every time the
ignition is turned to “OFF”. To re-enable the Tire Fill Alert
feature at the next ignition “RUN” state, the customer
must re-enable the feature through use of the customer
settings in the radio.
SELECTABLE TIRE FILL ALERT (STFA) —
IF EQUIPPED
The STFA system is an optional feature that is included as
part of the normal Tire Fill Alert system. The system is
designed to allow you to select a pressure to inflate or
deflate the vehicle's front and rear axle tires to, and to
provide feedback while inflating or deflating the vehicle's
tires.
NOTE:
To use the STFA feature, the Tire Fill Alert feature must be
enabled through use of the customer settings in the radio.
In the Selectable Tire Fill Alert application, which is located
in the apps menu of the Uconnect system, you will be able
to select a pressure setting for both the front and rear axle
tire pressures by scrolling through a pressure range from
XX to 15 psi in 1 psi increments for each axle setting.
XX = the vehicle's cold placard pressure values for the
front and rear axles as shown on the vehicle placard
pressure label.
You may also store pressure values chosen for each axle
in the Uconnect system application as preset pressure
values. Up to two sets of preset pressure values can be
stored in the Uconnect system for the front and rear axle.
Once you select the tire pressures for the front and rear
axles that you want to inflate or deflate to, you can begin
inflating or deflating one tire at a time.
NOTE:
The STFA system will only support inflating or deflating one
tire at a time.
The system will be activated when the TPMS receiver
module detects a change in tire pressure. The ignition
must be in the ON/RUN mode, with the transmission in
PARK in vehicles with an automatic transmission, and in
NEUTRAL with the parking brake engaged in vehicles with
a manual transmission. The hazard lamps will come on to
confirm the vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire pressure
screen will be displayed in the instrument cluster. If the
hazard lamps do not come on while inflating or deflating
the tire, the Tire Pressure Monitoring System sensor may
be in an inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle may
need to be moved slightly forward or backward.
Horn chirps will indicate STFA status as tires are inflated/
deflated. The horn will chirp under the following STFA
states:
1. The horn will chirp once when the selected pressure
is reached to let you know when to stop inflating or
deflating the tire.
2. The horn will chirp three times if the tire is overin
-
flated or over-deflated.
3. The horn will chirp once again when enough air is
added or removed to reach proper selected pressure
level.

RECAUTIONS
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:
1. Children 12 years old and under should always ride
buckled up in the rear seat of a vehicle with a rear
seat.
2. A child who is not big enough to wear the vehicle seat
belt properly must be secured in the appropriate child
restraint or belt-positioning booster seat in a rear
3. If a child from 2 to 12 years old (not in a rear-facing
child restraint) must ride in the front passenger seat,
move the seat as far back as possible and use the
4. Never allow children to slide the shoulder belt behind
them or under their arm.
5. You should read the instructions provided with your
child restraint to make sure that you are using it
properly.
6. All occupants should always wear their lap and
shoulder belts properly.
7. The driver and front passenger seats should be
moved back as far as practical to allow the front air
bags room to inflate.
8. Do not lean against the door or window. If your vehicle
has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between
occupants and the door and occupants could be
injured.
9. If the air bag system in this vehicle needs to be
modified to accommodate a disabled person, see
page 377 for customer service contact
information.

Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and could cause a collision that includes you. This can
happen far away from home or on your own street.
Research has shown that seat belts save lives, and they
can reduce the seriousness of injuries in a collision. Some
of the worst injuries happen when people are thrown from
the vehicle. Seat belts reduce the possibility of ejection
and the risk of injury caused by striking the inside of the
vehicle. Everyone in a motor vehicle should be belted at all
times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The
BeltAlert feature is active whenever the ignition switch is
in the START or ON/RUN position.
WARNING!
Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.
WARNING!

262
SAFETY
(Continued)
Initial Indication
If the driver is unbuckled when the ignition switch is first in
the START or ON/RUN position, a chime will signal for a
few seconds. If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat BeltAlert)
is unbuckled when the ignition switch is first in the START
or ON/RUN position the Seat Belt Reminder Light will turn
on and remain on until both outboard front seat belts are
buckled. The outboard front passenger seat BeltAlert is
not active when an outboard front passenger seat is
unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range
and the driver or outboard front seat passenger is
unbuckled (if equipped with outboard front passenger
seat BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard front passenger
seat is unoccupied). The BeltAlert warning sequence
starts by blinking the Seat Belt Reminder Light and
sounding an intermittent chime. Once the BeltAlert
warning sequence has completed, the Seat Belt Reminder
Light will remain on until the seat belts are buckled. The
BeltAlert warning sequence may repeat based on vehicle
speed until the driver and occupied outboard front seat
passenger seat belts are buckled. The driver should
instruct all occupants to buckle their seat belts.
Change Of Status
If the driver or outboard front seat passenger (if equipped
with outboard front passenger seat BeltAlert) unbuckles
their seat belt while the vehicle is traveling, the BeltAlert
warning sequence will begin until the seat belts are
buckled again.
The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other items
are placed on the outboard front passenger seat or when
the seat is folded flat (if equipped). It is recommended that
pets be restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat belts,
and cargo is properly stowed.
BeltAlert can be activated or deactivated by an authorized
dealer. FCA US LLC does not recommend deactivating
BeltAlert.
NOTE:
If BeltAlert has been deactivated and the driver or
outboard front seat passenger (if equipped with outboard
front passenger seat BeltAlert) is unbuckled the Seat Belt
Reminder Light will turn on and remain on until the driver
and outboard front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped with lap/
shoulder belts.
The seat belt webbing retractor will lock only during very
sudden stops or collisions. This feature allows the
shoulder part of the seat belt to move freely with you
under normal conditions. However, in a collision the seat
belt will lock and reduce your risk of striking the inside of
the vehicle or being thrown out of the vehicle.
WARNING!
Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some colli
-
sions, the air bags won’t deploy at all. Always wear
your seat belt even though you have air bags.
In a collision, you and your passengers can suffer
much greater injuries if you are not properly buckled
up. You can strike the interior of your vehicle or other
passengers, or you can be thrown out of the vehicle.
Always be sure you and others in your vehicle are
buckled up properly.
It is dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or
killed.
Do not allow people to ride in any area of your vehicle
that is not equipped with seats and seat belts.
Be sure everyone in your vehicle is in a seat and
using a seat belt properly. Occupants, including the
driver, should always wear their seat belts whether or
not an air bag is also provided at their seating posi
-
tion to minimize the risk of severe injury or death in
the event of a crash.

Lap/Shoulder Belt Operating Instructions
1. Enter the vehicle and close the door. Sit back and
adjust the seat.
2. The seat belt latch plate is above the back of the front
seat, and next to your arm in the rear seat (for
vehicles equipped with a rear seat). Grab the latch
plate and pull out the seat belt. Slide the latch plate
up the webbing as far as necessary to allow the seat
belt to go around your lap.
Pulling Out The Latch Plate
Wearing your seat belt incorrectly could make your
injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.
Two people should never be belted into a single seat
belt. People belted together can crash into one
another in a collision, hurting one another badly.
Never use a lap/shoulder belt or a lap belt for more
than one person, no matter what their size.
WARNING!
A lap belt worn too high can increase the risk of injury
in a collision. The seat belt forces won’t be at the
strong hip and pelvic bones, but across your
abdomen. Always wear the lap part of your seat belt
as low as possible and keep it snug.
A twisted seat belt may not protect you properly. In a
collision, it could even cut into you. Be sure the seat
belt is flat against your body, without twists. If you
can’t straighten a seat belt in your vehicle, take it to
an authorized dealer immediately and have it fixed.
A seat belt that is buckled into the wrong buckle will
not protect you properly. The lap portion could ride
too high on your body, possibly causing internal inju
-
ries. Always buckle your seat belt into the buckle
nearest you.
WARNING!
A seat belt that is too loose will not protect you prop
-
erly. In a sudden stop, you could move too far
forward, increasing the possibility of injury. Wear
your seat belt snugly.
A seat belt that is worn under your arm is dangerous.
Your body could strike the inside surfaces of the
vehicle in a collision, increasing head and neck
injury. A seat belt worn under the arm can cause
internal injuries. Ribs aren’t as strong as shoulder
bones. Wear the seat belt over your shoulder so that
your strongest bones will take the force in a collision.
A shoulder belt placed behind you will not protect you
from injury during a collision. You are more likely to
hit your head in a collision if you do not wear your
shoulder belt. The lap and shoulder belt are meant to
be used together.
A frayed or torn seat belt could rip apart in a collision
and leave you with no protection. Inspect the seat
belt system periodically, checking for cuts, frays, or
loose parts. Damaged parts must be replaced imme
-
diately. Do not disassemble or modify the seat belt
system. If your vehicle is involved in a collision, or if
you have questions regarding seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.

3. When the seat belt is long enough to fit, insert the
latch plate into the buckle until you hear a “click.”
Inserting Latch Plate Into Buckle
4. Position the lap belt so that it is snug and lies low
across your hips, below your abdomen. To remove
slack in the lap belt portion, pull up on the shoulder
belt. To loosen the lap belt if it is too tight, tilt the latch
plate and pull on the lap belt. A snug seat belt reduces
the risk of sliding under the seat belt in a collision.
Positioning The Lap Belt
5. Position the shoulder belt across the shoulder and
chest with minimal, if any slack so that it is
comfortable and not resting on your neck. The
retractor will withdraw any slack in the shoulder belt.
6. To release the seat belt, push the red button on the
buckle. The seat belt will automatically retract to its
stowed position. If necessary, slide the latch plate
down the webbing to allow the seat belt to retract
fully.
Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted lap/
shoulder belt.
1. Position the latch plate as close as possible to the
anchor point.
2. At about 6 to 12 inches (15 to 30 cm) above the latch
plate, grab and twist the seat belt webbing
180 degrees to create a fold that begins immediately
above the latch plate.
3. Slide the latch plate upward over the folded webbing.
The folded webbing must enter the slot at the top of
the latch plate.
4. Continue to slide the latch plate up until it clears the
folded webbing and the seat belt is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and outboard front passenger seats, the top
of the shoulder belt can be adjusted upward or downward
to position the seat belt away from your neck. Push or
squeeze the anchorage button to release the anchorage,
and move it up or down to the position that serves you
best.
Adjustable Upper Anchorage
As a guide, if you are shorter than average, you will prefer
the shoulder belt anchorage in a lower position, and if you
are taller than average, you will prefer the shoulder belt
anchorage in a higher position. After you release the
anchorage button, try to move it up or down to make sure
that it is locked in position.
NOTE:
The adjustable upper shoulder belt anchorage is equipped
with an Easy Up feature. This feature allows the shoulder
belt anchorage to be adjusted in the upward position
without pushing or squeezing the release button. To verify
the shoulder belt anchorage is latched, pull downward on
the shoulder belt anchorage until it is locked into position.
WARNING!
Wearing your seat belt incorrectly could make your
injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.
