WHAT TO DO IN EMERGENCIES
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.
WARNING!
