ParkSensewill remember the last system state (enabled
or disabled) from the last ignition cycle when the ignition
is changed to the RUN/ON 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 be active until the vehicle speed
is increased to approximately 11 mph (18 km/h) or
above. The system will be 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 orientation of the obstacle.

The system will indicate a detected obstacle by showing
three solid arcs and will produce a12second tone. As the
vehicle moves closer to the object the EVIC display will
show fewer arcs and the sound tone will change from
slow, to fast, to continuous.

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. For details, refer to “Personal Set-
tings (Customer-Programmable Features)” under “Elec-
tronic Vehicle Information Center (EVIC)” in Section 4.
When the ParkSense switch is pressed to
disable the system, the instrument cluster will
display the “PARK ASSIST DISABLED” mes-
sage for approximately five seconds. Refer to
“Electronic Vehicle Information Center (EVIC)”. When
the shift lever is moved to REVERSE and the system is
disabled, the EVIC will display the “PARK ASSIST DIS-
ABLED” message for as long as the vehicle is in RE-
VERSE. 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 defec-
tive, 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)”. 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.3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 169

If “SERVICE PARK ASSIST SYSTEM” appears in the
Electronic Vehicle Information Center (EVIC) after mak-
ing sure the rear fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction, see your
authorized dealer.
The ParkSensesystem uses four sensors located in the
rear bumper fascia to scan for obstacles up to 79 in
(200 cm) away from the rear bumper fascia. The warning
display located above in the Instrument Cluster’s EVIC
provides both visible and audible warnings to indicate
the range of the object.
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 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 DISABLED.” 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 instrument
cluster will display “PARK ASSIST DISABLED” mes-
sage for as long as the vehicle is in REVERSE.
170 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•If a ParkSensesystem malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM” and the
LED in the ParkSense switch will illuminate. If this
occurs after making sure the rear fascia/bumper is
clean and clear of snow, ice, mud, dirt, or other
obstruction, see your authorized dealer for service.
•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 must not be 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 instrument cluster.
CAUTION!
•ParkSense is 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.
