GETTING TO KNOW YOUR INSTRUMENT PANEL 107
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive. Always refer to the
information in this chapter in the event of a
failure indication. All active telltales will display
first if applicable. The system check menu may
appear different based upon equipment options
and current vehicle status. Some telltales are
optional and may not appear.
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

page 292.
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 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 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
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
