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 mal-
function or failure and require a sensor re-
alignment.
• If the sensor is damaged due to a collision,
see your authorized dealer for service.
• Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket 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.
NOTE:
• If the “Clean Radar Sensor In Front Of
Vehicle” 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 your
authorized dealer.
• Installing a snow plow, front-end protec-
tor, an aftermarket grille or modifying the
grille is not recommended. Doing so may
block the sensor and inhibit ACC opera-
tion.
Removing ACC Sensor For Off-Roading
NOTE:
When off-roading, it may be advisable to
remove the ACC sensor. The sensor is lo-
cated behind the front lower grille in the
center of the vehicle. After removing the
lower fascia, you may remove the lower
sensor and bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two
tabs on the connector and pulling it out. Do not
pull by the wiring or use any tools to remove the
connector.
2. Remove the wiring christmas tree attach-
ment from the back of the bracket. 3. Remove the two M6 fasteners that connect
the bracket to the bumper.
NOTE:
Do not change the adjustment fasteners or
pull the sensor off of the bracket. Doing so
may misalign the sensor.
Store the sensor and bracket assembly in a
safe location. The wiring and connector must
be stowed properly after the sensor and
bracket assembly is removed.
A connector plug is stowed on top of the
bumper beam. Insert the wiring connector into
the connector plug.
NOTE:
When the sensor is removed, Adaptive
Cruise Control, Normal Cruise Control, and
Forward Collision Warning will not be avail-
able. The cluster will display the warning
“ACC/FCW Unavailable - Service Radar Sen-
sor.”
To reinstall the sensor and bracket assembly
reverse the process above. The fastener torque
required to assembly the bracket back to the
beam is 6.6 ft lbs (9 Nm).

Service The ParkSensePark Assist
System
When the ParkSense Park Assist System is
malfunctioning, the instrument cluster will actu-
ate a single chime, once per ignition cycle. The
instrument cluster will display the “CLEAN
PARK ASSIST SENSORS” message when any
of the rear or front sensor(s) is blocked by
snow, mud, or ice and the vehicle is shifted into
REVERSE or DRIVE.
The instrument cluster will display the “SER-
VICE PARK ASSIST SYSTEM” message when
any of the rear or front sensors are damaged
and require service. When the shift lever is
moved to REVERSE or DRIVE and the system
has detected a faulted condition, the EVIC will
display the “CLEAN PARK ASSIST SENSORS”
or the “SERVICE PARK ASSIST SYSTEM” mes-
sage for as long as the vehicle is in REVERSE
or DRIVE (at speeds less than
11 mph/18 km/h). Under this condition Park-
Sense will not operate. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in-
formation. If the “CLEAN PARK ASSIST SENSORS” mes-
sage appears in the Electronic Vehicle Informa-
tion Center (EVIC) make sure the rear fascia/
bumper and/or front 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.
Cleaning The ParkSense
SystemClean 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 sen-
sors. Otherwise, you could damage the sen-
sors.
ParkSense System Usage
Precautions
NOTE:
• Ensure that the front and rear bumper are
free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating
properly.
• Jackhammers, large trucks, and other vi-
brations could affect the performance of
ParkSense. •
When you turn ParkSense off, the instru-
ment cluster will display “PARK ASSIST
SYSTEM OFF.” Furthermore, once you
turn ParkSense off, it remains off until
you turn it on again, even if you cycle the
ignition key.
• When you move the shift lever to the
REVERSE or DRIVE position and Park-
Sense is turned off, the instrument clus-
ter will display “PARK ASSIST SYSTEM
OFF” message for as long as the vehicle
is in REVERSE and when the vehicle is in
DRIVE at or below 11 mph (18 km/h).
• ParkSense, when on, will MUTE 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 ParkSense 
system might not detect an obstacle be-
hind or in front of the fascia/bumper, or it
could provide a false indication that an
obstacle is behind or in front of the fascia/
bumper.
