RECAUTIONS
NOTE:
Ensure that the front and rear fascias/bumpers

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


YSTEM
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) of 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.
STARTING AND OPERATING
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 vehi-
cles 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.
