contained in the Owner's Manual, which you are
advised to read carefully in all cases. Always

Red Warning Lights

— Seat Belt Reminder Warning Light
This 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 Restraints
Systems" in "Safety" for further information.
— Air Bag Warning Light
This light indicates 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 driv-
ing, have the system inspected at an authorized
dealer as soon as possible.
— Brake Warning Light
This light monitors various brake functions, in-
cluding brake fluid level and parking brake ap-
plication. 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.
