RECAUTIONS
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 vibra-

tions could affect the performance of
ParkSense.
When you turn ParkSense off, the instrument

cluster will display "PARKSENSE OFF." Further-
more, 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 is turned off,
the instrument cluster will display "PARKSENSE
OFF" 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
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 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 WIPE REAR
SENSORS" message to be displayed in the
instrument cluster.
ParkSense should be disabled when the liftgate

is in the open position. An opened liftgate 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.
Before using ParkSense, it is strongly recom-

mended that the ball mount and hitch ball
assembly be 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 vehicle 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.
