If the light stays on, or comes on
while driving, the vehicle control
system may be malfunctioning. Take
the vehicle to your dealer for service
as soon as possible.
Brake System Warning
Light
This light should come on briefly
when the engine control switch is
turned to the ON position, and then
should go out after the engine is
started.
Brake System Warning Light
If the light remains on after engine
start up or comes on during
operation of the vehicle, it means
that there is something wrong with
part of the brake system.
The brake system warning light
comes on while the engine is
running (after startup) in the
following situations:
.
Drop in the level of brake fluid
(due to brake lining wear or fluid
leakage).
.
Abnormality in the charging
system (such as an alternator
malfunction or loose or split
fan belt).
.
Abnormality in the anti-lock
brake system (ABS) and EBD
functions. (The ABS warning
light and brake system warning
light will illuminate at the same
time.) See
To serve as a reminder, the light
should stay on when the parking
brake is not fully released, and the
engine control switch is on. Have
the system repaired if the light does
not come on when it should. If this
warning light does not go away,
brake inspection and maintenance
should be performed.
Check and Corrective Action
1. Check to see that the parking
brake has been fully released.
If it has, check the following:
2. For diesel vehicles, turn on the
exhaust brake to help slow the
vehicle.
3. Pull off the road and stop
carefully. Remember that
stopping distances may be
longer, the pedal may be
harder to push and go down
farther than normal.
4. Check the brake fluid reservoir
on the left side of the
instrument panel. If low, add
fluid as needed.
5. If the brake fluid is not low: Try
out the brakes by starting and
stopping on the shoulder of the
road, then either drive
cautiously at a safe speed to
the nearest dealer for repair,
if you judge driving to be safe;
or have the vehicle towed to
the nearest dealer for repair.
