292 STARTING AND OPERATING
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the SET (-)
button and release. The instrument cluster display will show
the set speed.
If the system is set when the vehicle speed is below 20 mph
(32 km/h), the set speed shall be defaulted to 20 mph
(32 km/h). If the system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary vehicle in front of
your vehicle in close proximity.
Remove your foot from the accelerator pedal, after the ACC
has been set. If you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
• The message “ACC DRIVER OVERRIDE” will display in the instrument cluster display.
• The system will not be controlling the distance between your vehicle and the vehicle ahead. The vehicle speed will
only be determined by the position of the accelerator
pedal.
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 (over -
heated).

298 STARTING AND OPERATING
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.

STARTING AND OPERATING 303
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 315
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.
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.

STARTING AND OPERATING 325
(Continued)
• Clean the ParkSense sensors regularly, taking care not toscratch 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 or in
front of the fascia/bumper, or it could provide a false indi -
cation that an obstacle is behind or in front of the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system off if obstacles such as bicycle carriers, trailer hitches, etc. are
placed within 18 inches (45 cm) from the rear fascia/
bumper. Failure to do so can result in the system misinter -
preting a close obstacle as a sensor problem, causing the
“Front/Rear ParkSense Unavailable Service Required”
message to be appear in the instrument cluster display.
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.
• Before using ParkSense, it is strongly recommendedthat the ball mount and hitch ball assembly is discon -
nected from the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia when
the loudspeaker sounds the continuous tone. Also, the
sensors could detect the ball mount and hitch ball
assembly, depending on its size and shape, giving a
false indication that an obstacle is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it is unable to recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using Park -
Sense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.
