ParkSensewill 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 lever
position, the system will remain active until the vehicle
speed is increased to approximately 11 mph (18 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
10 mph (16 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 12 in (30 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.

switch LED will be OFF when the system is enabled.
Service The ParkSense Rear Park Assist System
When the ParkSenseRear 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 has detected 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.

ParkSenseSystem Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense system operat-
ing 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 .
