Selec-Terrain combines the capabilities of the
vehicle control systems, along with driver input, to
provide the best performance for all terrains.
Selec-Terrain Switch
Selec-Terrain consists of the following positions:
SNOW – Tuning set for additional stability in
inclement weather. Use on and off-road on
loose traction surfaces such as snow. When in
SNOW mode (depending on certain operating
conditions), the transmission may use SECOND
gear (rather than FIRST gear) during launches,
to minimize wheel slippage. If equipped with air
suspension, the default ride height for SNOW is
Normal Ride Height (NRH).
STARTING AND OPERATING
107
AUTO – Fully automatic full-time four-wheel
drive operation can be used on and off-road.
Balances traction with seamless steering feel to
provide improved handling and acceleration
over two-wheel drive vehicles. If equipped with
air suspension, the level will change to Normal
Ride Height (NRH) unless in the Off-Road 1
(OR1) or Off-Road 2 (OR2) position, the height of
OR1 or OR2 will be maintained.
SAND – Off-road calibration for use on low trac
-
tion surfaces such as sand or wet grass. Drive
-
line is maximized for traction. Some binding may
be felt on less forgiving surfaces. The electronic
brake controls are set to limit traction control
management of throttle and wheel spin. If
equipped with air suspension, the default ride
height for SAND is Normal Ride Height (NRH).
MUD – Off-road calibration for use on low trac
-
tion surfaces such as mud. Driveline is maxi
-
mized for traction. Some binding may be felt on
less forgiving surfaces. The electronic brake
controls are set to limit traction control manage
-
ment of throttle and wheel spin. If equipped with
air suspension, the level will change to OR1.
ROCK – Off-road calibration is only available in
4WD LOW range. The vehicle is raised (if
equipped with Air Suspension) for improved
ground clearance. Traction based tuning with
improved steerability for use on high traction
off-road surfaces. Use for low speed obstacles
such as large rocks, deep ruts, etc. If equipped
with air suspension, the vehicle level will change
to Off-Road 2. If the Selec-Terrain switch is in
ROCK mode, and the transfer case is switched
out of 4WD LOW, the Selec-Terrain system will

(ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
utilizes a radar sensor and a forward-facing
camera designed to detect a vehicle directly ahead
of you to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica
-
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli
-
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
WARNING!
Adaptive Cruise Control (ACC) is a conve
-
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi
-
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn
-
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi
-
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for two seconds in the stop
position. If the target vehicle does not
start moving within two seconds the ACC
system will display a message that the
system will release the brakes and that
the brakes must be applied manually.
An audible chime will sound when the
brakes are released.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa
-
tions (i.e., in highway construction zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving
at a constant speed.

If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre
-
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+), or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre
-
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:
When you override and push the SET (+) button or
SET (-) buttons, the new set speed will be the
current speed of the vehicle.
When ACC Is Active:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system applies the brake down to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.

116
STARTING AND OPERATING
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.
Distance Settings
To increase the distance setting, push the
Distance Increase button and release. Each time
the button is pushed, the distance setting
increases by one bar (longer).
To decrease the distance setting, push the
Distance Decrease button and release. Each time
the button is pushed, the distance setting
decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the ACC Set With Target
Detected Light. The system will then adjust vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the distance set by
the driver until:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this occurs,
a visual alert “BRAKE!” will flash in the instrument
cluster display and a chime will sound while ACC
continues to apply its maximum braking force.
NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
STARTING AND OPERATING
117
Overtake Aid
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn
signal and will only be active when passing on the
left hand side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill
while following a vehicle ahead, your vehicle will
resume motion, without any driver interaction, if
the vehicle ahead starts moving within two
seconds of your vehicle coming to a standstill.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the ACC with Stop system will cancel and the
brakes will release. A cancel message will display
on the instrument cluster display and produce a
warning chime. The driver must now manually
operate the vehicle’s accelerator and brakes.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or the
driver door is opened, the ACC with Stop system
will cancel and the brakes will release. A cancel
message will display on the instrument cluster
display and produce a warning chime. The driver
must now manually operate the vehicle’s
accelerator and brakes.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and a chime will
sound when conditions temporarily limit system
performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system may
also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
the above message and the system will deactivate.
This message can sometimes be displayed while
driving in highly reflective areas (i.e. ice and snow,
or tunnels with reflective tiles). The ACC system will
recover after the vehicle has left these areas.
Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the center of the vehicle behind the lower grille.
To keep the ACC System operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc
-
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after
-
market grilles. Doing so could cause an ACC
system failure or malfunction.
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.

STARTING AND OPERATING
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield and fog on the inside of glass. In
these cases, the instrument cluster display will
display “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have
degraded performance.
This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW system will recover after the vehicle has left
these areas. Under rare conditions, when the
camera is not tracking any vehicles or objects in its
path this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
mirror. They may require cleaning or removal of an
obstruction.
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the windshield and
forward-facing camera inspected at an authorized
dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW Unavailable Service Required”,
there may be an internal system fault or a
temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable
under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended when using ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.
Offset Driving Condition Example
STARTING AND OPERATING
119
TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may increase or decrease the vehicle
speed for stability, with no vehicle ahead detected.
Once the vehicle is out of the curve the system will
resume your original set speed. This is a part of
normal ACC system functionality.
NOTE:
On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on
hills. ACC may not detect a vehicle in your lane
depending on the speed, vehicle load, traffic
conditions, and the steepness of the hill.
ACC Hill Example
LANE CHANGING
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the
following lane changing example, ACC has not yet
detected the vehicle changing lanes and it may not
detect the vehicle until it's too late for the ACC
system to take action. ACC may not detect a
vehicle until it is completely in the lane. There may
not be sufficient distance to the lane-changing
vehicle. Always be attentive and ready to apply the
brakes if necessary.
Lane Changing Example
NARROW VEHICLES
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the lane.
There may not be sufficient distance to the vehicle
ahead.
Narrow Vehicle Example

STARTING AND OPERATING
STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or
vehicles. For example, ACC will not react in
situations where the vehicle you are following exits
your lane and the vehicle ahead is stopped in your
lane. It will consider this stopped vehicle a
stationary object as it did not previously detect
movement from it. Always be attentive and ready
to apply the brakes if necessary.
Stationary Object And Stationary Vehicle Example
PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, the front fascia/bumper
and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver).
The vehicle brakes may be automatically applied
and released when performing a reverse parking
maneuver if the system detects a possible collision
with an obstacle.
NOTE:
The driver can disable the automatic braking
function by turning ParkSense off via the Park
-
Sense switch. The driver can also override auto
-
matic braking by shifting out of REVERSE or by
pressing the gas pedal over 90% of its capacity
during the braking event.
Automatic brakes are not available if ESC is not
available.
Automatic brakes are not available if the vehicle
is in 4WD Low.
Automatic brakes will not be available if there is
a faulted condition detected with the ParkSense
Park Assist system or the Braking System
Module.
The automatic braking function may only be
applied if the vehicle deceleration is not enough
to avoid colliding with a detected obstacle.
The automatic braking function may not be
applied fast enough for obstacles that move
toward the rear of the vehicle from the left and/
or right sides.
The automatic braking function can be
enabled/disabled from the Customer Program
-
mable Features section of the Uconnect system.
ParkSense will retain its last known configura
-
tion state for the automatic braking function
through ignition cycles.
STARTING AND OPERATING
121
The automatic braking function is intended to
assist the driver in avoiding possible collisions with
detected obstacles when backing up in REVERSE
gear.
NOTE:
The system is designed to assist the driver and
not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking and is
responsible for the vehicle's movements.
For limitations of this system and
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is changed to the ON/RUN
position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. The system will become active
again if the vehicle speed is decreased to speeds
less than approximately 6 mph (9 km/h). A display
warning will appear in the instrument cluster
display if the vehicle is in REVERSE and the speed
exceeds 7 mph (11 km/h).

ENSORS
The six ParkSense sensors (there may only be four,
depending on the vehicle options), located in the
rear fascia/bumper, and the six ParkSense
sensors located in the front fascia/bumper
(if equipped), monitor the area in front and behind
the vehicle that is within the sensors’ field of view.
The front sensors detect obstacles from
approximately 12 inches (30 cm) up to 47 inches
(120 cm) from the front fascia/bumper. The rear
sensors can detect obstacles from approximately
12 inches (30 cm) up to 79 inches (200 cm) from
the rear fascia/bumper. These distances depend
on the location, type and orientation of the
obstacle in the horizontal direction.

The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in the left and/or right front or
rear regions based on the object’s distance and
location relative to the vehicle.
If an object is detected in the left and/or right rear
region, the display will show a single arc in the left
and/or right rear region and the system will
produce a tone. As the vehicle moves closer to the
object, the display will show the single arc moving
closer to the vehicle and the tone will change from
a single 1/2 second tone to slow, to fast, to
continuous.
