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 bumper is free of snow, ice, mud, dirtand debris to keep the ParkSense system operating prop -
erly.
• Jackhammers, large trucks, and other vibrations could affect the performance of ParkSense.
• 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 properly. The Park -Sense 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 misin -
terpreting 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, ParkSense should be disabled when the tailgate is in the lowered or open posi -
tion 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.

STARTING AND OPERATING 387
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear, and/or
front fascia/bumper, and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
Refer to “ParkSense System Usage Precautions” in this
section for limitations of this system and recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these
gear selector positions, the system will remain active until
the vehicle speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the instrument
cluster display when the vehicle is in REVERSE, indicating
the vehicle is above ParkSense operating speed. The system
will become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is discon -
nected 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 indication that an obstacle is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it is 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.
• The vehicle must be driven slowly when using Park -
Sense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.

ParkSense Sensors
The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is within
the sensors’ field of view.
The sensors can detect obstacles from approximately
18 inches (45 cm) up to 79 inches (200 cm) from the rear
fascia/bumper in the horizontal direction, depending on the
location, type and orientation of the obstacle.
NOTE:
If equipped as a dually, the ParkSense system has six rear
sensors to assist in detection around the dually flares.
The six ParkSense sensors, located in the front fascia/
bumper, monitor the area in front of the vehicle that is within
the sensors’ field of view. The sensors can detect obstacles
from approximately 12 inches (30 cm) up to 47 inches (120cm) from the front fascia/bumper in the horizontal direction,
depending on the location, type and orientation of the
obstacle.
ParkSense Warning Display
The ParkSense Warning screen is located within the instru-
ment cluster display. It provides visual warnings to indicate
