PARKSENSE® REAR PARK ASSIST — IF
EQUIPPED
The ParkSense® Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense® System
Usage Precautions 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 shift lever is in
REVERSE. If ParkSense® is enabled at this shift leverposition, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
6 mph (9 km/h).
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 in (45 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
246 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:The ParkSense® system will automatically dis-
able when the system detects that a trailer with trailer
brakes has been connected to the Integrated Trailer Brake
Module. The EVIC will display “PARKSENSE OFF”
message for as long as the vehicle is in reverse.
The ParkSense® switch LED will be ON when ParkSense®
is disabled or defective. The ParkSense® switch LED will
be OFF when the system is enabled.
Service The ParkSense® Rear Park Assist
System
When the ParkSense® Rear Park Assist System is mal-
functioning, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
“CLEAN PARK ASSIST SENSORS” or the “SERVICE
PARK ASSIST SYSTEM” message. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information. When
the shift lever is moved to REVERSE and the system hasdetected a faulted condition, the EVIC will display the
“PARK ASSIST SYSTEM OFF” message for as long as the
vehicle is in REVERSE. Under this condition, ParkSense
will not operate.
If “CLEAN PARK ASSIST SENSORS” appears in the
Electronic Vehicle Information Center (EVIC) make sure
the outer surface and the underside of the rear fascia/
bumper is clean and clear of snow, ice, mud, dirt or other
obstruction and then cycle the ignition. If the message
continues to appear, see an authorized dealer.
If “SERVICE PARK ASSIST SYSTEM” appears in the
EVIC, see an authorized dealer.
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 dam-
age the sensors.

ParkSense® System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense® system oper-
ating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®.
•When you turn ParkSense® off, the instrument cluster
will display “PARK ASSIST SYSTEM OFF.” Further-
more, once you turn ParkSense® off, it remains off
until you turn it on again, even if you cycle the ignition
key.
•When you move the shift lever to the REVERSE
position and ParkSense® is turned off, the EVIC will
display “PARK ASSIST SYSTEM OFF” message for as
long as the vehicle is in REVERSE.•ParkSense®, when on, will MUTE 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 the fascia/bumper, or it could provide
a false indication that an obstacle is behind the
fascia/bumper.
•Objects such as bicycle carriers, trailer hitches, etc.,
must not be placed within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the EVIC .

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 253

•On vehicles equipped with a tailgate, ParkSense®
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.
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
ParkSense® 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®.
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 assem-
bly 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

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
