— 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 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.
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.

— Battery Charge Warning Light
This warning light will illuminate when the battery is not
charging properly. If it stays on while the engine is running,
there may be a malfunction with the charging system.
Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine oil
pressure. If the light turns on while driving, stop the vehicle,
shut off the engine as soon as possible, and contact an autho -
rized dealer. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Oil Temperature Warning Light
This warning light will illuminate to indicate the engine oil
temperature is high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. Wait
for oil temperature to return to normal levels. — Electronic Throttle Control (ETC) Warning Light
This warning light will illuminate to indicate a problem with
the Electronic Throttle Control (ETC) system. If a problem is
detected while the vehicle is running, the light will either
stay on or flash depending on the nature of the problem.
Cycle the ignition when the vehicle is safely and completely
stopped and the transmission is placed in the PARK position.
The light should turn off. If the light remains on with the
vehicle running, your vehicle will usually be drivable;
however, see an authorized dealer for service as soon as
possible.
NOTE:
This light may turn on if the accelerator and brake pedals are
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.
