300 STARTING AND OPERATING
When you move the gear selector into

REVERSE with ParkSense turned off, the
instrument cluster display will show "Off" on
the vehicle graphic arcs 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.
Ensure the ParkSense system is off if objects

such as bicycle carriers, trailer hitches, etc.,
are placed within 18 inches (45 cm) of the
rear fascia/bumper while driving the vehicle.
Failure to do so can result in the system
misinterpreting a close obstacle as a sensor
problem, causing the "Rear ParkSense
Unavailable Service Required" message to
appear in the instrument cluster display.
On vehicles equipped with a tailgate, Park-

Sense should be disabled when the tailgate
is in the lowered or open position and the
vehicle is in REVERSE. A lowered tailgate
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.
WARNING! (Continued)
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 continuous
tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica-
tion that an obstacle is behind the vehicle.
ParkSense is only a parking aid and it is

(Continued)
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above or
below the sensors will not be detected
when they are in close proximity.
CAUTION!
