PARKSENSEREAR PARK ASSIST — IF
EQUIPPED
The ParkSenseRear 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 ParkSenseSystem
Usage Precautions for limitations of this system and
recommendations.
ParkSensewill retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSensecan be active only when the shift lever is in
REVERSE. If ParkSenseis 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).
ParkSenseSensors
The four ParkSensesensors, 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.
ParkSenseWarning Display
The ParkSenseWarning screen will only be displayed if
Sound and Display is selected from the Customer- Pro-
grammable Features section of the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.

When the vehicle is in REVERSE, the warning display
will turn ON indicating the system status.

tion Center (EVIC)/Personal Settings (Customer-

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 233

“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. When the shift lever is moved to REVERSE and the
system is disabled, the EVIC will display the “PARK
ASSIST SYSTEM OFF” message for as long as the vehicle
is in REVERSE.
The ParkSenseswitch LED will be ON when Park-
Senseis disabled or defective. The ParkSenseswitch
LED will be OFF when the system is enabled.
Service The ParkSenseRear 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 hasdetected a faulted condition, the EVIC will display the
“CLEAN PARK ASSIST SENSORS” or the “SERVICE
PARK ASSIST SYSTEM” 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 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 ParkSenseSystem
Clean the ParkSensesensors 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 ParkSensesystem operat-
ing properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSenseoff, the instrument cluster
will display “PARK ASSIST SYSTEM OFF.” Further-
more, once you turn ParkSenseoff, 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 ParkSenseis 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 ParkSensesensors 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 ParkSensesystem 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.
