Service ACC/FCW Warning
If the system turns off, and the EVIC displays “ACC/FCW
Unavailable Service Required”or “Cruise/FCW Unavail-
able Service Required”, there may be an internal system
fault or a temporary malfunction that limits ACC function-
ality. Although the vehicle is still drivable under normal
conditions, ACC will be temporarily unavailable. If this
occurs, try activating ACC again later, following a key
cycle. If the problem persists, see your authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpectedly.
The driver needs to stay alert and may need to intervene.
Towing A Trailer
NOTE:Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

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 lever
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
above. When in REVERSE and above the system’s oper-
ating speed, a warning will appear in the EVIC indicating
the vehicle speed is too fast. 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 12 in (30 cm) up to 79 in

Enabling And Disabling ParkSense®
ParkSense® can be enabled and disabled with the
ParkSense® switch.
When the ParkSense® switch is pressed to dis-
able the system, the instrument cluster will
display the “PARKSENSE OFF” message for
approximately five seconds. 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 is
disabled, the EVIC will display the “PARKSENSE OFF”
message for as long as the vehicle is in REVERSE.
The ParkSense® switch LED will be ON when ParkSense®
is disabled or requires service. The ParkSense® switch LED
will be OFF when the system is enabled. If the ParkSense®
switch is pressed, and the system requires service, the
ParkSense® switch LED will blink momentarily, and then
the LED will be ON.
Service The ParkSense® Rear Park Assist
System
During vehicle start up, when the ParkSense® Rear Park
Assist System has detected a faulted condition, the
instrument cluster will actuate a single chime, once
per ignition cycle, and it will display the “PARKSENSE
UNAVAILABLE WIPE REAR SENSORS” or the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
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 condi-
tion, the EVIC will display the PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS orPARKSENSE UN-
AVAILABLE SERVICE REQUIRED message for as long
as the vehicle is in REVERSE. Under this condition,
ParkSense® will not operate.

If “PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS” 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 “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
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 clus-
ter will display “PARKSENSE 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 EVIC will
display “PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.

•ParkSense®, when on, will reduce the volume of 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.
• Use the ParkSense® switch to turn the ParkSense®
system OFF if objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 in (30 cm) from the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be displayed in the
EVIC. •
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®.
