•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.

CAUTION!(Continued)
•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 ParkSense®. Always check carefully
behind your vehicle, look behind you, and be sure
to check for pedestrians, 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.

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 the#PARKSENSE UNAVAILABLE SERVICE RE-
QUIRED#message 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 front and rear bumper are free of snow,
ice, mud, dirt and debris to keep the ParkSense®
system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 207

•When you turn Front or Rear ParkSense® off, the
instrument cluster will display “FRONT PARKSENSE
OFF” or “REAR PARKSENSE OFF.” Furthermore,
once you turn Front or Rear 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 Front or Rear ParkSense® is turned off,
the instrument cluster will display#FRONT
PARKSENSE OFF#or#REAR PARKSENSE OFF#mes-
sage for five seconds, followed by a car graphic with
#OFF#in the corresponding side. This car graphic will
be displayed 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 or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
•Use the ParkSense® switch to turn the ParkSense®
system off if obstacles such as bicycle carriers, trailer
hitches, etc. are placed within 18 in (45 cm) from the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close obstacle as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be displayed in the
instrument cluster.
•On vehicles equipped with a tailgate, ParkSense®
should be disabled when the tailgate is in the lowered
or open position. A lowered tailgate could provide a
false indication that an obstacle is behind the vehicle.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The tachometer indicates engine speed in Revolutions
Per Minute (RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
operation over 3200 RPM (Redline) can result in
significant damage that will not be covered under the
New Vehicle Limited Warranty.
2. 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.
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.
3. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part
of an onboard diagnostic (OBDII) system
which monitors the emissions and engine con-
trol system. If the vehicle is ready for emissions
testing, the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
4

testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
(Continued)
CAUTION!(Continued)
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
4. Turn Signal Indicators
The arrow will flash with the exterior turn
signal when the turn signal lever is operated.
290 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:
•A continuous chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn
signal on.
•Check for an inoperative outside light bulb if either
indicator remains on and does not flash, or flashes at
a rapid rate.
5. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.
6. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
4
UNDERSTANDING YOUR INSTRUMENT PANEL 291

hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
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 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
