This light comes on briefly when the engine is turned
on. If it does not come on then, have it fixed so it will
be ready to warn if there is a problem.
When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
will stay on if the parking brake does not release fully.
If it stays on after the parking brake is fully released, it
means there is a brake problem.
If the light comes on while driving, pull off the road and
stop carefully.The pedal may be harder to push, or the
pedal may go closer to the floor. It may take longer to
stop. If the light is still on, have the vehicle towed for
service. See Towing Your Vehicle on page 5‑29.

The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
