Brake Warning Light This warning light monitors various brake func -
tions, including brake fluid level and parking brake
application. If the brake light turns on it may indi -
cate 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 will remain on until the cause is corrected. NOTE:
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.
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.

Seat Belt Reminder Warning Light When the ignition is first placed in the ON/RUN or
MAR/ON/RUN position, 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.
Transmission Fault Warning Light
This light will illuminate (together with a message in
the instrument cluster display and a buzzer) to indi -
cate a transmission fault. Contact your authorized
dealer if the message remains after restarting the engine. Engine Oil Level Warning Light
This warning light appears on the panel when the
engine oil level falls below the minimum recom -
mended value. Restore the correct engine oil level or
contact your authorized dealer for service.
Yellow Warning Lights
Anti-Lock Brake System (ABS) Warning Light

This light monitors the Anti-Lock Brake System (ABS).
The light will turn on when the ignition is placed in the
ON/RUN or MAR/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. 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 is placed
in the ON/RUN or MAR/ON/RUN position, have the light
inspected by an authorized dealer.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.

SAFETY
SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel Anti-Lock Brake System (ABS) is designed
to aid the driver in maintaining vehicle control under
adverse braking conditions. The system operates with a
separate computer to modulate hydraulic pressure, to
prevent wheel lock-up and to help avoid skidding on
slippery surfaces.
The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When the
light is illuminated, the ABS is not functioning. The system
reverts to standard non-anti-lock brakes. Turning the igni-
tion OFF and ON again may reset the ABS if the fault
detected was only momentary.
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.
• The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking
or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the traction
afforded.

98 SAFETY
When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as the
vehicle comes to a stop. This is the result of the system
reverting to the base brake system.
Engagement of the ABS may be accompanied by a pulsing
sensation. You may also hear a clicking noise. These occur-
rences are normal and indicate that the system is functioning
properly.
Electronic Brake Control (EBC) System
Your vehicle is equipped with an advanced Electronic Brake
Control (EBC) system that includes the Brake Assist System
(BAS), Traction Control System (TCS), Hill Start Assist
(HSA), Electronic Stability Control (ESC), Electronic Roll
Mitigation (ERM) and Trailer Sway Control (TSC). All
systems work together to enhance vehicle stability and
control in various driving conditions and are commonly
referred to as ESC.
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to optimize the
vehicle’s braking capability during emergency braking
maneuvers. The system detects an emergency braking situa -
tion by sensing the rate and amount of brake application and
then applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous braking
pressure during the stopping sequence, (do not “pump” the
brakes). Do not reduce brake pedal pressure unless braking
is no longer desired. Once the brake pedal is released, the
BAS is deactivated.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.

Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver Knee
Air Bag mounted in the instrument panel below the steering
column. The Supplemental Driver Knee Air Bag provides
enhanced protection during a frontal impact by working
together with the seat belts, pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs are
marked with “SRS AIRBAG” or “AIRBAG” on a label or on
the seat trim on the outboard side of the seats.Supplemental Seat-Mounted Side Air Bag Label
The SABs may help to reduce the risk of occupant injury
during certain side impacts, in addition to the injury reduc -
tion potential provided by the seat belts and body structure.
When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant
and the door. The SAB moves at a very high speed and with
such a high force that it could injure occupants if they are not
