The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and requires service, the
ParkSense switch LED will blink momen-
tarily, and then the LED will be on.
ParkSense System Usage Precautions
NOTE:
Ensure that the rear bumper is free of
snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense off, the instru -
ment cluster display will read “PARK -
SENSE OFF.” Furthermore, once you turn
ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
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 ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
Use the ParkSense switch to turn the
ParkSense system off if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 inches (30 cm) from the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a
close object as a sensor problem, causing
the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be
displayed 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 atten -
tion to your surroundings. Failure to do
so can result in serious injury or death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected 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 contin -
uous 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.

Service The ParkSense Park Assist System
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single
chime, once per ignition cycle, and it will
display the “PARKSENSE UNAVAILABLE
WIPE REAR SENSORS”, “PARKSENSE
UNAVAILABLE WIPE FRONT SENSORS” or
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message. When the gear
selector is moved to REVERSE and the
system has detected a faulted condition, the
instrument cluster display will display a car
graphic with an overlay saying “Wipe Off” or
“Service”. Under this condition, ParkSense
will not operate. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instru-
ment Panel” for further information.
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” or “PARKSENSE UNAVAILABLE
WIPE FRONT SENSORS” appears in the
instrument cluster display make sure the
outer surface and the underside of 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
authorized dealer. If the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message appears in
the instrument cluster display, see an autho
-
rized 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. In washing stations, clean
sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4 inches
(10 cm) from the sensors. Do not scratch or
poke the sensors. Otherwise, you could
damage the sensors.
ParkSense System Usage Precautions
NOTE:
Ensure that the front and rear bumpers are
free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating
properly.
Jackhammers, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense System off, the
instrument cluster display will show the
“ParkSense Off” message for two seconds.
Furthermore, once you turn ParkSense off, it remains off until you turn it on again,
even if you cycle the ignition.
When you move the gear selector to the
REVERSE position and ParkSense System
is turned off, the instrument cluster
display will show the “ParkSense Off”
message. This message will be displayed
for as long as the vehicle is in REVERSE.

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 behind 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.
Use the ParkSense switch to turn the
