and clear of snow, ice, mud, dirt or other

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 fascia/bumper is 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."
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 is turned
off, the instrument cluster display will display
"PARKSENSE OFF" message 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 prop-
erly. The ParkSense 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.
Use the ParkSense switch to turn the Park-

Sense 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.
ParkSense should be disabled when the lift-

gate is in the open position and the vehicle is
in REVERSE. An open 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.
