STARTING AND OPERATING 359
Adaptive Cruise Control (ACC) Operation
The speed control buttons (located on the right side of the
steering wheel) operate the ACC system.Adaptive Cruise Control Buttons
NOTE:
Any chassis/suspension or tire size modifications to the
vehicle will effect the performance of the Adaptive Cruise
Control and Forward Collision Warning System.
• Will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle for
approximately two seconds in the stop position. At
this point, there will be an “ACC may cancel soon”
chime and warning to the driver. When ACC is
cancelled, the system will release the brakes and the
driver must take over braking. The system can be
resumed when the target vehicle drives off by
releasing the brake and pushing the resume button
on the steering wheel.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow, sleet, heavy traffic, and complex driving situations (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.

To Cancel
The following conditions cancel the system:
• The brake pedal is applied.
• The CANC (cancel) button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
• The gear selector is removed from the DRIVE position.
• The Electronic Stability Control/Traction Control System(ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
• A Trailer Sway Control (TSC) event occurs.
• The driver switches ESC to full-off mode.

• The braking temperature exceeds normal range (overheated).

To Turn Off
The system will turn off and clear the set speed in memory if:
• The Adaptive Cruise Control (ACC) on/off button is pushed. • The Normal (Fixed Speed) Cruise Control on/off button is
pushed.
• The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory push the RES (+) button and
then remove your foot from the accelerator pedal. The instru-
ment cluster display will display the last set speed.
NOTE:
• If your vehicle stays at standstill for longer than two seconds, the driver will have to push the RES (+) button to
reengage the ACC to the existing set speed.
• ACC cannot be resumed if there is a stationary vehicle in-front of your vehicle in close proximity.
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.

STARTING AND OPERATING 367
Brake Alert
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.
Trailer Detect — If Equipped
When a trailer is detected, the ACC system automatically
defaults to the longest setting (four bars). The setting can be
overridden by pushing the Distance Button on the steering
wheel.
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 addi -
tional 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
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, if the target
vehicle starts moving within two seconds of your vehicle
coming to a standstill, your vehicle will resume motion
without the need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, then ACC will
cancel and the driver must take over braking. When the
target vehicle drives off, ACC can be resumed by releasing
the brake and pushing the RES (+) button.5

372 STARTING AND OPERATING
• Do not put stickers or easy passes over the camera/radarfield of view.
• Any modifications to the vehicle that may obstruct the field of view of the radar/camera are not recommended.
Cleaning Instructions
Dust and dirt can accumulate on the cover and block the
camera lens. Clean the camera lens with a soft microfiber
cloth, being careful not to damage or scratch the module.
Towing A Trailer
ACC while towing a trailer is recommended only with an
Integrated Trailer Brake Controller. Aftermarket trailer
brake controllers will not activate the trailer brakes when
ACC is braking. 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 accel
-
erate unexpectedly.
Offset Driving Condition Example

STARTING AND OPERATING 385
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with the ParkSense
switch.When the gear selector is moved to REVERSE and
the system is disabled, the instrument cluster
display will show the vehicle graphic with “Off”
over the arcs for as long as the vehicle is in REVERSE.
NOTE:
The ParkSense system will automatically disable when the
system detects that a trailer with trailer brakes has been
connected to the Integrated Trailer Brake Module. The
instrument cluster display will show an “Off” message over
the arcs if the ParkSense system is off, or a “Trailer” message
if the system is on, for as long as the vehicle is in REVERSE.
The ParkSense switch LED will be on when ParkSense is
disabled or defective. The ParkSense switch LED will be off
when the system is enabled.
If the ParkSense switch is pushed, and the system is disabled
or requires service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the Rear ParkSense System
has detected a faulted condition, the instrument cluster
display will show the "Rear ParkSense Unavailable Service
Required" or the "Rear ParkSense Unavailable Wipe Sensors"
message.
When the gear selector is moved into REVERSE, a vehicle
graphic will show in the instrument cluster display, along
with the display overlay “Rear ParkSense Unavailable Wipe
Sensors.” If the system needs service, the display overlay will
read “Rear ParkSense Unavailable Service Required” Under
this condition, ParkSense will not operate.
If "Rear ParkSense Unavailable Wipe Sensors" appears in the
instrument cluster display make sure the outer surface and
the underside of the rear fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction, and then cycle the
ignition. If the message continues to appear, see an autho -
rized dealer.
If "Rear ParkSense Unavailable Service Required" appears in
the instrument cluster display, see an authorized dealer.

Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap and
a soft cloth. Do not use rough or hard cloths. Do not scratch
or poke the sensors. Otherwise, you could damage the
sensors.
ParkSense System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow, ice, mud, dirtand debris to keep the ParkSense system operating prop -
erly.
• Jackhammers, large trucks, and other vibrations could affect the performance of ParkSense.
• When you move the gear selector into REVERSE with ParkSense turned off, the instrument cluster display will
show "Off" on the vehicle graphic arcs for as long as the
vehicle is in REVERSE.
• ParkSense, when on, will reduce the volume of the radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, taking care not to scratch or damage them. The sensors must not be covered
with ice, snow, slush, mud, dirt or debris. Failure to do so
can result in the system not working properly. The Park -Sense system might not detect an obstacle behind the
fascia/bumper, or it could provide a false indication that
an obstacle is behind the fascia/bumper.
• Ensure the ParkSense system is OFF if objects such as bicycle carriers, trailer hitches, etc., are placed within
18 inches (45 cm) of the rear fascia/bumper while driving
the vehicle. Failure to do so can result in the system misin -
terpreting a close obstacle as a sensor problem, causing the
"Rear ParkSense Unavailable Service Required" message
to appear in the instrument cluster display.
• On vehicles equipped with a tailgate, ParkSense should be disabled when the tailgate is in the lowered or open posi -
tion and the vehicle is in REVERSE. A lowered tailgate
could provide a false indication that an obstacle is behind
the vehicle.
WARNING!
• Drivers must be careful when backing up even when using ParkSense. 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. You are responsible for
safety and must continue to pay attention to your
surroundings. Failure to do so can result in serious
injury or death.
