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) or Driver Information Display (DID)” for further
information. When the shift lever/gear selector is moved
to REVERSE and the system has detected a faulted
condition, the EVIC/DID will display the#PARKSENSE
UNAVAILABLE WIPE REAR SENSORS#or
#PARKSENSE UNAVAILABLE 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) or Driver Information Display (DID) 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/DID, 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/
DID 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/DID.
•ParkSense® should be disabled when the liftgate is in
the open position and the vehicle is in REVERSE. An
open liftgate could provide a false indication that an
obstacle is behind the vehicle.

“PARKSENSE OFF” message for approximately five sec-
onds. Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” or
“Driver Information Display (DID)” for further informa-
tion. When the shift lever is moved to REVERSE and the
system is disabled, the EVIC/DID 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 re-
quires service, the ParkSense® switch LED will blink
momentarily, and then the LED will be ON.

After five seconds, a car graphic will be displayed with
#UNAVAILABLE#at either the front or rear sensor loca-
tion depending on where the fault is detected. The
system will continue to provide arc alerts for the side that
is functioning properly. These arc alerts will interrupt the

•There may be a delay in the object detection rate if the
object is moving. This will cause the automatic braking
application to be delayed.

The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
If brake failure is indicated, immediate repair is
necessary.
6. Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)
The odometer display shows the total distance the ve-
hicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.
When the appropriate conditions exist, this display
shows the EVIC/DID messages. Refer to “Electronic
Vehicle Information Center (EVIC)” or “Driver Informa-
tion Display (DID” as equipped located in “Understand-
ing Your Instrument Panel.”
7. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.

UNDERSTANDING YOUR INSTRUMENT PANEL 333

If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
8. ECO Light
This light is activated via hard button on the center stack
to display your driving habits.
9. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the
engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
