Red Warning Lights
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
— Air Bag Warning Light
This warning light will illuminate to indicate a fault with the
air bag, and will turn on for four to eight seconds as a bulb
check when the ignition is placed in the ON/RUN or ACC/
ON/RUN position. This light will illuminate with a single
chime when a fault with the air bag has been detected, it will
stay on until the fault is cleared. If the light is either not on
during startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as possible. — Brake Warning Light
This warning 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
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 capacity 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 spec -
ified level.

The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The vehicle
should have service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair is necessary.
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 approximately
two seconds. The light should then turn off unless theparking 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 position.
NOTE:
This light shows only that the parking brake is applied. It
does not show the degree of brake application.

pressed at the same time.
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have the
system checked by an authorized dealer. — Electric Power Steering Fault Warning Light

This warning light will turn on when there's a fault with the
Electric Power Steering (EPS) system. Refer to “Power Steering”
in “Starting And Operating” for further information.
— Tailgate Open Warning Light
This warning light will illuminate when the tailgate is open.
NOTE:
If the vehicle is moving, there will also be a single chime.
— Trailer Brake Disconnected Warning Light
This warning light will illuminate when the Trailer Brake has
been disconnected.
— Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to warn of a high transmis -
sion fluid temperature. This may occur with strenuous usage
such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the trans -
mission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive normally.
WARNING!

— Electronic Park Brake Warning Light
This warning light will illuminate to indicate the Electronic
Park Brake is not functioning properly and service is
required. Contact an authorized dealer. — Electronic Stability Control (ESC) Active Warning
Light — If Equipped
This warning light will indicate when the Electronic Stability
Control system is Active. The “ESC Indicator Light” in the
instrument cluster will come on when the ignition is placed
in the ON/RUN or ACC/ON/RUN position, and when ESC
is activated. It should go out with the engine running. If the
“ESC Indicator Light” comes on continuously with the
engine running, a malfunction has been detected in the ESC
system. If this warning light remains on after several ignition
cycles, and the vehicle has been driven several miles (kilome -
ters) at speeds greater than 30 mph (48 km/h), see an autho -
rized dealer as soon as possible to have the problem
diagnosed and corrected.
• The “ESC Off Indicator Light” and the “ESC Indicator Light” come on momentarily each time the ignition is
placed in the ON/RUN or ACC/ON/RUN position.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when
ESC becomes inactive.
• This light will come on when the vehicle is in an ESC event.
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.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.

This warning light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition is placed in
the ON/RUN or ACC/ON/RUN position and may stay on
for as long as four seconds. If the ABS light remains on or turns on while driving, then
the Anti-Lock portion of the brake system is not functioning
and service is required as soon as possible. However, the
conventional brake system will continue to operate
normally, assuming the Brake Warning Light is not also on.
If the ABS light does not turn on when the ignition is placed
in the ON/RUN or ACC/ON/RUN position, have the brake
system inspected by an authorized dealer.
— Rear Axle Locker Fault Indicator Light — If
Equipped
This warning light will illuminate to indicate when a rear
axle locker fault has been detected.
— Service Forward Collision Warning (FCW) Light —
If Equipped
This warning light will illuminate to indicate a fault in the
Forward Collision Warning System. Contact an authorized
dealer for service.
Refer to “Forward Collision Warning (FCW) With Mitiga -
tion” in “Safety” for further information.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size equipped
on your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your
authorized dealer to have your sensor function checked.

SAFETY
SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most braking
conditions. The system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the ABS
is working properly each time the vehicle is started and
driven. During this self-check, you may hear a slight clicking
sound as well as some related motor noises.
ABS is activated during braking when the system detects one
or more wheels begin to lock. Road conditions such as ice,
snow, gravel, bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS activates:
• The ABS motor noise (it may continue to run for a shorttime after the stop)
• The clicking sound of solenoid valves • Brake pedal pulsations
• A slight drop of the brake pedal at the end of the stop
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated electronic equipment that may be susceptible to interference caused by
improperly installed or high output radio transmitting
equipment. This interference can cause possible loss of
anti-lock braking capability. Installation of such equip -
ment should be performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
