PARKSENSEREAR 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 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.
ParkSense Warning Display
The ParkSense Warning 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.

Enabling And Disabling ParkSense
ParkSensecan be enabled and disabled with a switch
located in the switch bank of the instrument panel or
through the Customer-Programmable Features section of
the EVIC. The available choices are: OFF, Sound Only, or
Sound and Display. Refer to “Electronic Vehicle Informa-
tion Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.
When the ParkSense switch is pressed to
disable the system, the instrument cluster will
display the “PARK ASSIST OFF” message for
approximately five seconds. Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
When the shift lever is moved to REVERSE and the
system is disabled, the EVIC will display the “PARK
ASSIST OFF” message for as long as the vehicle is in
REVERSE. The ParkSense
switch LED will be ON when Park-
Sense 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 ParkSenseRear Park Assist System is mal-
functioning, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
“SERVICE PARK ASSIST SYSTEM” message. Refer to
“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 has detected a faulted condition, the EVIC will
display the “SERVICE PARK ASSIST SYSTEM” message
for as long as the vehicle is in REVERSE. Under this
condition, ParkSense will not operate.
If “SERVICE PARK ASSIST SYSTEM” appears in the
EVIC, see your authorized dealer.

Cleaning The ParkSenseSystem
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 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 OFF.” Furthermore, 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 instrument
cluster will display “PARK ASSIST 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
3

object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the EVIC.
CAUTION!
•ParkSenseis only a parking aid and it is unable
to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected 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 the ParkSense Rear Park Assist Sys-
tem. Always check carefully behind your vehicle,
look behind you, and be sure to check for pedes-
trians, 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.
