(ABS)

The ABS provides increased vehicle stability and

brake performance under most braking conditions.

The system automatically prevents wheel lock, and

enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that

the ABS is working properly each time the vehicle

is started and driven. During this self-check, you

may hear a slight clicking sound as well as some

related motor noises.
ABS is activated during braking when the system

detects one or more wheels are beginning to lock.

Road conditions such as ice, snow, gravel, bumps,

railroad tracks, loose debris, or panic stops may

increase the likelihood of ABS activation(s).
You also may experience the following normal

characteristics when ABS activates:



The ABS motor noise or clicking sounds (you

may continue to hear for a short time after the

stop)



Brake pedal pulsations



A slight drop of the brake pedal at the end of the

stop

ABS is designed to function with the Original

Equipment Manufacturer (OEM) tires. Modification

may result in degraded ABS performance.

Anti-Lock Brake System (ABS) Warning

Light

The yellow ABS Warning Light will turn on when the

ignition is placed in the ON/RUN mode and may

stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on

while driving, it indicates that the anti-lock portion

of the brake system is not functioning and that

service is required. However, the conventional

brake system will continue to operate normally if

the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system

should be serviced as soon as possible to restore

the benefits of Anti-Lock brakes. If the ABS

WARNING!



The ABS contains sophisticated electronic

equipment that may be susceptible to interfer

-

ence caused by improperly installed or high

output radio transmitting equipment. This

interference can cause possible loss of

anti-lock braking capability. Installation of

such equipment should be performed by qual

-

ified professionals.



Pumping of the Anti-Lock Brakes will diminish

their effectiveness and may lead to a collision.

Pumping makes the stopping distance longer.

Just press firmly on your brake pedal when you

need to slow down or stop.



The ABS cannot prevent the natural laws of

physics from acting on the vehicle, nor can it

increase braking or steering efficiency beyond

that afforded by the condition of the vehicle

brakes and tires or the traction afforded.



The ABS cannot prevent collisions, including

those resulting from excessive speed in turns,

following another vehicle too closely, or hydro

-

planing.



The capabilities of an ABS equipped vehicle

must never be exploited in a reckless or

dangerous manner that could jeopardize the

user’s safety or the safety of others.

YSTEM

Your vehicle is equipped with an advanced

Electronic Brake Control (EBC) system. This system

includes Anti-Lock Brake System (ABS), Brake

Assist System (BAS), Electronic Brake Force

Distribution (EBD), Hill Start Assist (HSA),

Electronic Roll Mitigation (ERM), Electronic

Stability Control (ESC), and Traction Control

System (TCS). These systems work together to

enhance both vehicle stability and control in

various driving conditions.
Your vehicle may also be equipped with Trailer

Sway Control (TSC) and Hill Descent Control (HDC).

Brake Assist System (BAS)

The BAS is designed to optimize the vehicle’s

braking capability during emergency braking

maneuvers. The system detects an emergency

braking situation by sensing the rate and amount

of brake application and then applies optimum

pressure to the brakes. This can help reduce

braking distances. The BAS complements the

Anti-Lock Brake System (ABS). Applying the brakes

very quickly results in the best BAS assistance. To

receive the benefit of the system, you must apply

continuous braking pressure during the stopping

sequence (do not “pump” the brakes). Do not

reduce brake pedal pressure unless braking is no

longer desired. Once the brake pedal is released,

the BAS is deactivated.

Brake System Warning Light

The red Brake System Warning Light will turn on

when the ignition is placed in the ON/RUN mode

and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or

comes on while driving, it indicates that the brake

system is not functioning properly and that

immediate service is required. If the Brake System

Warning Light does not come on when the ignition

is placed in the ON/RUN mode, have the light

repaired as soon as possible.

Electronic Brake Force Distribution (EBD)

EBD manages the distribution of the braking

torque between the front and rear axles by limiting

braking pressure to the rear axle. This is done to

prevent overslip of the rear wheels to avoid vehicle

instability, and to prevent the rear axle from

entering ABS before the front axle.

Electronic Roll Mitigation (ERM)

ERM anticipates the potential for wheel lift by

monitoring the driver’s steering wheel input and

the speed of the vehicle. When ERM determines

that the rate of change of the steering wheel angle

and vehicle’s speed are sufficient to potentially

cause wheel lift, it then applies the appropriate

brake and may also reduce engine power to lessen

the chance that wheel lift will occur. ERM can only

reduce the chance of wheel lift occurring during

severe or evasive driving maneuvers; it cannot

prevent wheel lift due to other factors, such as

road conditions, leaving the roadway, or striking

objects or other vehicles.
NOTE:

ERM is disabled any time the ESC is in “Full Off”

mode (if equipped). For a complete explanation of

the available ESC modes, see

Ú

page 237.

WARNING!

The Brake Assist System (BAS) cannot prevent

the natural laws of physics from acting on the

vehicle, nor can it increase the traction afforded

by prevailing road conditions. BAS cannot

prevent collisions, including those resulting from

excessive speed in turns, driving on very slippery

surfaces, or hydroplaning. The capabilities of a

BAS-equipped vehicle must never be exploited in

a reckless or dangerous manner, which could

jeopardize the user's safety or the safety of

others.

SAFETY

237

(Continued)

Electronic Stability Control (ESC)

ESC enhances directional control and stability of

the vehicle under various driving conditions. ESC

corrects for oversteering or understeering of the

vehicle by applying the brake of the appropriate

wheel(s) to counteract the above conditions.

Engine power may also be reduced to help the

vehicle maintain the desired path.



Oversteer — when the vehicle is turning more

than appropriate for the steering wheel position.



Understeer — when the vehicle is turning less

than appropriate for the steering wheel position.

ESC uses sensors in the vehicle to determine the

vehicle path intended by the driver and compares

it to the actual path of the vehicle. When the actual

path does not match the intended path, ESC

applies the brake of the appropriate wheel to

assist in counteracting the oversteer or understeer

condition.
The ESC Activation/Malfunction Indicator Light

located in the instrument cluster will start to flash

as soon as the ESC system becomes active. The

ESC Activation/Malfunction Indicator Light also

flashes when the TCS is active. If the ESC

Activation/Malfunction Indicator Light begins to

flash during acceleration, ease up on the

accelerator and apply as little throttle as possible.

Be sure to adapt your speed and driving to the

prevailing road conditions.

ESC Operating Modes

Depending upon model and mode of operation, the

ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC

system. Whenever the vehicle is started, the ESC

system will be in this mode. This mode should be

used for most driving conditions. Alternate ESC

modes should only be used for specific reasons as

noted in the following paragraphs.

WARNING!

Many factors, such as vehicle loading, road condi

-

tions and driving conditions, influence the chance

that wheel lift or rollover may occur. ERM cannot

prevent all wheel lift or roll overs, especially those

that involve leaving the roadway or striking objects

or other vehicles. The capabilities of an

ERM-equipped vehicle must never be exploited in

a reckless or dangerous manner which could jeop

-

ardize the user's safety or the safety of others.

WARNING!



Electronic Stability Control (ESC) cannot

prevent the natural laws of physics from acting

on the vehicle, nor can it increase the traction

afforded by prevailing road conditions. ESC

cannot prevent accidents, including those

resulting from excessive speed in turns, driving

on very slippery surfaces, or hydroplaning. ESC

also cannot prevent accidents resulting from

loss of vehicle control due to inappropriate

driver input for the conditions. Only a safe,

attentive, and skillful driver can prevent acci

-

dents. The capabilities of an ESC equipped

vehicle must never be exploited in a reckless or

dangerous manner which could jeopardize the

user’s safety or the safety of others.



Vehicle modifications, or failure to properly

maintain your vehicle, may change the

handling characteristics of your vehicle, and

may negatively affect the performance of the

ESC system. Changes to the steering system,

suspension, braking system, tire type and size

or wheel size may adversely affect ESC perfor

-

mance. Improperly inflated and unevenly worn

tires may also degrade ESC performance. Any

vehicle modification or poor vehicle mainte

-

nance that reduces the effectiveness of the

ESC system can increase the risk of loss of

vehicle control, vehicle rollover, personal

injury and death.

Partial Off
This mode may be useful if the vehicle becomes

stuck. This mode may modify TCS and ESC

thresholds for activation, which allows for more

wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push

the ESC OFF button and the ESC OFF Indicator

Light will illuminate. To turn the ESC on again,

momentarily push the ESC OFF button and the ESC

OFF Indicator Light will turn off.
NOTE:

For vehicles with multiple partial ESC modes, the

push and release of the button will toggle the ESC

modes. Multiple attempts may be required to

return to "ESC On" mode.

Full Off — If Equipped
This mode is intended for off-highway or off-road

use only and should not be used on any public

roadways. In this mode, TCS and ESC features are

turned off. To enter the “Full Off” mode, push and

hold the ESC OFF button for five seconds while the

vehicle is stopped with the engine running. After five

seconds, a chime will sound, the ESC OFF Indicator

Light will illuminate, and the “ESC OFF” message

will display in the instrument cluster. To turn ESC on

again, momentarily push the ESC OFF button.
NOTE:

System may switch from ESC “Full Off” to “Partial

Off” mode when vehicle exceeds a predetermined

speed. When the vehicle speed slows below the

predetermined speed the system will return to ESC

“Full Off”.
ESC modes may also be affected by drive modes (if

equipped).

ESC Activation/Malfunction Indicator Light

And ESC OFF Indicator Light

The ESC Activation/Malfunction Indicator

Light in the instrument cluster will come

on when the ignition is placed in the ON

mode. It should go out with the engine

running. If the ESC Activation/Malfunction

Indicator Light comes on continuously with the

engine running, a malfunction has been detected

in the ESC system. If this light remains on after

several ignition cycles, and the vehicle has been

driven several miles (kilometers) at speeds greater

than 30 mph (48 km/h), see an authorized dealer

as soon as possible to have the problem

diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light

starts to flash as soon as the tires lose traction and

the ESC system becomes active. The ESC

Activation/Malfunction Indicator Light also flashes

when TCS is active. If the ESC Activation/

Malfunction Indicator Light begins to flash during

acceleration, ease up on the accelerator and apply

as little throttle as possible. Be sure to adapt your

speed and driving to the prevailing road conditions.

The ESC OFF Indicator Light indicates

that the Electronic Stability Control (ESC)

is in a reduced mode.

NOTE:



The ESC Activation/Malfunction Indicator Light

and the ESC OFF Indicator Light come on

momentarily each time the ignition is placed in

the ON position.



Each time the ignition is placed in the ON posi

-

tion, the ESC system will be on even if it was

turned off previously.



The ESC system will make buzzing or clicking

sounds when it is active. This is normal; the

sounds will stop when ESC becomes inactive

following the maneuver that caused the ESC

activation.

Hill Descent Control (HDC) — If Equipped

HDC is intended for low speed off-road driving

while in 4WD Low. HDC maintains vehicle speed

while descending hills during various driving

situations. HDC controls vehicle speed by actively

controlling the brakes.

HDC 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 HDC
HDC is enabled by pushing the HDC switch, but the

following conditions must also be met to enable

HDC:



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.

Activating HDC
Once HDC is enabled it will activate automatically

if driven down a grade of sufficient magnitude. The

set speed for HDC is selectable by the driver, and

can be adjusted by using the gear shift +/-. The

following summarizes the HDC set speeds:

HDC Target Set Speeds



P = No set speed. HDC may be enabled but will

not activate.



R = 0.6 mph (1 km/h)



N = 1.2 mph (2 km/h)



D = 0.6 mph (1 km/h)



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 = 5.0 mph (8 km/h)



9th = 5.6 mph (9 km/h) – If Equipped

NOTE:

During HDC the +/- shifter input is used for HDC

target speed selection, but will not affect the gear

chosen by the transmission. When actively

controlling HDC the transmission will shift appro

-

priately for the driver-selected set speed and corre

-

sponding driving conditions.
Driver Override
The driver may override HDC activation with

throttle or brake application at any time.

6

240

SAFETY

Deactivating HDC
HDC will be deactivated but remain available if any

of the following conditions occur:



Driver overrides HDC set speed with throttle or

brake application.



Vehicle speed exceeds 20 mph (32 km/h) but

remains below 40 mph (64 km/h).



Vehicle is on a downhill grade of insufficient

magnitude, is on level ground, or is on an uphill

grade.



Vehicle is shifted to PARK.

Disabling HDC
HDC will be deactivated and disabled if any of the

following conditions occur:



The driver pushes the HDC switch.



The driveline is shifted out of 4WD Low.



The parking brake is applied.



The driver door opens.



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) (HDC exits immediately).



HDC detects excessive brake temperature.

Feedback To The Driver
The instrument cluster has an HDC icon and the

HDC switch has an LED icon, which offers feedback

to the driver about the state HDC is in.



The cluster icon and switch lamp will illuminate

and remain on solid when HDC is enabled or

activated. This is the normal operating condition

for HDC.



The cluster icon and switch lamp 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 lamp will flash for

several seconds then extinguish when HDC

disables due to excess speed.



The cluster icon and switch lamp 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)

HSA 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.



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 trans

-

mission is in PARK or NEUTRAL. For vehicles

equipped with a manual transmission, if the

clutch is pressed, HSA will remain active.

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.

SAFETY

241

Disabling And Enabling HSA

This feature can be turned on or turned off. To

change the current setting, proceed as follows:



If disabling HSA using your instrument cluster

display, see

Ú

page 78 for further information.



If disabling HSA using Uconnect Settings, see

Ú

page 194 for further information.

Towing With HSA

HSA will also provide assistance to mitigate roll

back while towing a trailer.

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 power

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 weight recommendations

Ú

page 170.

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!

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 pulling 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 conditions. 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 accel

-

eration, 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.



Failure to follow these warnings can result in a

collision or serious personal injury.

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.

QUIPPED

FCW with Mitigation provides the driver with

audible warnings, visual warnings (within the

instrument cluster display), and may apply a brake

jerk to warn the driver when it detects a potential

frontal collision. The warnings and limited braking

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 the 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 brake jerk warning.
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 an 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 will be deactivated

Ú

page 387.

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 guard rails 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.



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 unnec

-

essary warnings to the surroundings.

Turning FCW On or Off

The FCW button is located in the Uconnect display

in the control settings

Ú

page 194.

NOTE:



When the FCW is “on”, this allows the system to

warn the driver of a possible collision with the

vehicle in front.

WARNING!

Forward Collision Warning (FCW) is not intended

to avoid a collision on its own, nor can FCW

detect every type of potential collision. The driver

has the responsibility to avoid a collision by

controlling the vehicle via braking and steering.

Failure to follow this warning could lead to

serious injury or death.

SAFETY

243



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 collision with the vehicle in

front using audible/visual warnings and it

applies autonomous braking.



The FCW system state is defaulted to “Full On”

from one ignition cycle to the next. If the system

is turned off, it will reset to “Full On” when the

vehicle is restarted.

FCW Braking Status And Sensitivity

The FCW sensitivity and Active Braking status are

programmable through the Uconnect system

Ú

page 194.



Far



When the sensitivity of FCW is set to the

“Far” setting and the system status is

“Warning and Braking”, 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.



Medium



When the sensitivity of FCW is set to the

“Medium” setting and the system status is

“Warning and Braking”, this allows the

system to warn the driver of a possible colli

-

sion with the vehicle in front using audible/

visual warnings.



Near



When the sensitivity of FCW is set to the

“Near” setting and the system status is

“Warning and Braking”, 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 experi

-

ence.



More dynamic or aggressive drivers that

want to avoid frequent warnings may prefer

this setting.

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.

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.

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 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

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

Ú

page 350 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 TPMS 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. 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.
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.

For example, your vehicle may have a

recommended cold (parked for more than three

hours) placard pressure of 30 psi (207 kPa). If the

ambient temperature is 68°F (20°C) and the

measured tire pressure is 27 psi (186 kPa), a

temperature drop to 20°F (-7°C) will decrease the

tire pressure to approximately 23 psi (158 kPa).

This tire pressure is sufficiently low enough to turn

on the TPMS Warning Light. Driving the vehicle

may cause the tire pressure to rise to

approximately 27 psi (186 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 pressure value

CAUTION!



The TPMS has been optimized for the original

equipment 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 equipment

that is not of the same size, type, and/or style.

Aftermarket wheels can cause sensor

damage.

SAFETY

245

NOTE:



The TPMS is not intended to replace normal tire

care and maintenance or to provide warning of

a tire failure or condition.



If your vehicle is not equipped with the Tire Fill

Alert feature the TPMS should not be used as a

tire pressure gauge while adjusting your tire

pressure.



Driving on a significantly underinflated tire

causes the tire to overheat and can lead to tire

failure. Underinflation also reduces fuel effi

-

ciency and tire tread life, and may affect the

vehicle’s handling and stopping ability.



The TPMS is not a substitute for proper tire

maintenance, and it is the driver’s responsibility

to maintain correct tire pressure using an accu

-

rate 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

pressure, and the TPMS will monitor the actual

tire pressure in the tire.

Example: Tire Pressure Monitoring System Display

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.

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 Tire Pressure Monitoring System

Warning Light will illuminate in the

instrument cluster when tire pressure is

low in one or more of the four active road

tires. The instrument cluster will display a graphic

showing the pressure values of each tire with the

low tire pressure values in a different color. An

"Inflate to XX" message will also be displayed.



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

dealership to have your sensor function

checked.



After inspecting or adjusting the tire pressure

always reinstall the valve stem cap. This will

prevent moisture and dirt from entering the

valve stem, which could damage the TPMS

sensor.

CAUTION!

SAFETY

Example: Low Tire Pressure Display

Should this occur, you should stop as soon as

possible and inflate the tires with a low pressure

condition (those in a different color in the

instrument cluster graphic) to the vehicle’s

recommended cold placard pressure inflation

value as shown in the "Inflate to XX" message.

Once the system receives the updated tire

pressures, the system will automatically update,

the graphic display in the instrument cluster will

return to its original color, and the Tire Pressure

Monitoring System Warning Light will turn 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.

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 Tire Pressure Monitoring System

Warning Light off.

Service TPMS Warning

If a system fault is detected, the Tire Pressure

Monitoring System Warning Light will flash on and

off for 75 seconds and then remain on solid. In

addition, the instrument cluster will display a

"SERVICE TPM 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 switch is cycled, this sequence will

repeat, providing the system fault still exists. If the

system fault no longer exists, the Tire Pressure

Monitoring System Warning Light will no longer

flash, and the "SERVICE TPM 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:



Signal interference due to electronic devices or

driving next to facilities emitting the same radio

frequencies as the TPMS sensors.



Installing aftermarket window tinting that

contains materials that may block radio wave

signals.



Accumulation of snow or ice around the wheels

or wheel housings.



Using tire chains on the vehicle.



Using wheels/tires not equipped with TPMS

sensors.

A system fault may occur due to an incorrect TPMS

sensor location condition. When a system fault

occurs due to an incorrect TPMS sensor location,

the Tire Pressure Monitoring System 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 “Tire Pressure Temporarily Unavailable”

message in place of the tire pressure display

screen. If the ignition switch is cycled, this

sequence will repeat, providing the system fault

still exists. If the system fault no longer exists, the

Tire Pressure Monitoring System Indicator Light

will no longer flash and the tire pressure display

screen will be displayed showing the tire pressure

values in the correct locations.

SAFETY

247

Vehicles With Non-Matching Full Size Spare Or

Compact Spare



The non-matching full size spare or compact

spare tire does not have a TPMS sensor. There

-

fore, the TPMS will not monitor the pressure in

the non-matching full size spare or compact

spare tire.



If you install the non-matching full size spare or

compact spare tire in place of a road tire that

has a pressure below the low-pressure warning

limit, upon the next ignition switch cycle, the

TPMS Warning Light and a “LOW TIRE” message

will remain on and a chime will sound. In addi

-

tion, the graphic in the instrument cluster will

still display a pressure value in a different color

and an “Inflate to XX” message.



After driving the vehicle for up to 20 minutes

above 15 mph (24 km/h), the TPMS Warning

Light will flash on and off for 75 seconds and

then remain on solid. In addition, the instrument

cluster will display a "SERVICE TPM SYSTEM"

message for a minimum of five seconds and then

display dashes (- -) in place of the pressure value.



For each subsequent ignition switch cycle, a

chime will sound, the TPMS Warning Light will

flash on and off for 75 seconds and then remain

on solid, and the instrument cluster will display

a "SERVICE TPM SYSTEM" message for a

minimum of five seconds and then display

dashes (- -) in place of the pressure value.



Once you repair or replace the original road tire

and reinstall it on the vehicle in place of the non

matching full size spare or compact spare, the

TPMS will update automatically. In addition, the

TPMS Warning Light will turn off and the graphic

in the instrument cluster will display a new pres

-

sure value instead of dashes (- -), as long as no

tire pressure is below the low-pressure warning

limit in any of the four active road tires. 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.

Trailer Tire Pressure Monitoring System

(TTPMS) — If Equipped

The Trailer Tire Pressure Monitoring System

(TTPMS) is a feature that displays the trailer tire

pressure values and warns the driver of a low tire

pressure event based on the drivers set target tire

pressure value, through TTPMS settings found in

the radio.
The TTPMS monitors the pressure of each tire and

warns the driver through the instrument cluster,

when either a low tire pressure condition falls below

25% of the driver’s set pressure or if a system

malfunction occurs. The instrument cluster will

display the actual tire pressure or dashes for each of

the trailer tires in the correct trailer position, based

on trailer configuration. The TTPMS can support up

to 12 trailer tires per configured trailer on up to four

configurable trailers

Ú

page 194.

Trailer Tire Pressure Monitoring System

Trailer Tire Pressure Sensor Pairing
In order use this feature, the provided tire pressure

sensors must be installed in the desired trailer

tires and the sensors must be paired to the truck.

If the target trailer requires more than the provided

four sensors, additional sensors can be purchased

at an authorized Ram dealership.
With the sensors installed and the trailer near or

connected to your Ram truck, initiate the pairing

process by entering the settings menu in the radio

and select trailer. Select the desired trailer profile

to pair to, open the “Tire Pressure” menu, and hit

“Setup All Tires.”

Trailer Tire Pressure Settings

Trailer Tire Pressure Pairing

Follow the on screen prompts to select the number

of axles (1 - 3), the number of trailer tires (2, 4, 6,

8, or 12), and the set trailer tire pressure. The

range is selectable anywhere between 25-125 psi

(172-862 kPa).
Once psi (kPa) is programmed, the pairing screen

appears. Tire sensors must be paired in order

shown. Starting with Tire 1, deflate tire by 5 psi

(34 kPa) and wait for a horn chirp. It may take up

to three minutes for the chirp to occur, indicating

that the sensor has paired. Repeat process on

each tire, in order, until complete. Do not exit the

pairing screen until process is complete. If pairing

was unsuccessful, a double horn chirp will sound,

and a prompt on the touchscreen will allow you to

retry the procedure; “Retry” will only appear when

setup fails. Each tire must be successfully paired

during a single pairing process to receive the

success screen.
NOTE:

If the pairing process times out after three minutes

of no communication with a sensor, a double horn

chirp will occur indicating the pairing has failed and

a message will display on the radio indicating the

process was unsuccessful. Under certain circum

-

stances, the double horn chirp may continue to

happen every three minutes indicating the failed

pairing. If this happens, the horn chirping may be

canceled by cycling the ignition button OFF and

then back to ON/RUN position.

Tire Pressure Monitoring System Low Pressure

Warnings
When a low tire pressure in one or more of the

active road tires is detected, the instrument cluster

will display a message stating “Trailer Tire

Pressure Low”. The instrument cluster will then

display the TTPMS graphic showing the pressure

values of each tire with the low tire pressure values

in a different color.
Should this occur, you should stop as soon as

possible and inflate the tires with a low pressure

condition (those in a different color in the

instrument cluster graphic) to the customer

programmed target tire pressure value as shown

at the top of the TTPMS instrument cluster graphic.

Once the tire(s) are inflated, the system will

automatically update the graphic display in the

instrument cluster, returning to its original color.

The vehicle may need to be driven for up to

10 minutes above 15 mph (24 km/h) in order for

the TTPMS to receive the updated information.
Service TTPMS Warning
If a system fault is detected, the instrument cluster

will display a “Trailer Tire Pressure System Service

Required” message for a minimum of five seconds.
Once the system fault is corrected the "Trailer Tire

Pressure System Service Required" message will

no longer be displayed. The vehicle may need to be

SAFETY

249

driven for up to 10 minutes above 15 mph

(24 km/h) in order for the TTPMS to receive the

trailer tire pressure information.
Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”

message will be displayed in the Instrument

Cluster on the TTPMS instrument cluster graphic

when a trailer number is selected that has not had

trailer tire pressure sensors paired

Ú

page 194.

Trailer Sensors Detected Do Not Match Active

Trailer
The “Trailer Sensors Detected Do Not Match Active

Trailer” message will be displayed in the

instrument cluster when the trailer sensors being

received by the TTPMS module do not match the

trailer sensors paired to the current trailer number

selected. This message will be displayed when the

sensors being received completely match the

sensors paired to another trailer number

configured in the TTPMS module.
To correct this condition, the correct trailer number

must be selected in the radio

Ú

page 194.

System Limitations
TTPMS may have difficulty transmitting through

steel-walled tires or on trailers longer than 30 ft. It

is recommended to use standard tires and trailers

less than 30 ft long to avoid drop outs or difficulty

when pairing.

NOTE:

The vehicle may not be driven until the pairing

process is complete.

Tire Fill Alert — If Equipped

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 through use of the customer

settings in the radio.
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).

The system will be activated when the TPMS

receiver module detects a change in tire pressure.

The ignition must be in the RUN mode, with the

transmission in PARK (P).
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 TPMS sensor may be in a null spot

preventing the TPMS sensor signal from being

received. In this case, the vehicle may need to be

moved either forward or backward slightly to exit

the null spot.
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 over

-

filled 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.
