WHAT TO DO IN EMERGENCIES
BRAKE
- Brake Warning Light
• This 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.
• 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 the parking
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.
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.
