This light should come on briefly when you turn the ignition to RUN. If it does not come on then, have it fixed so it will be ready to warn you if there is a problem.

Your vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well.

If the brake system warning light comes on, there is a brake problem. Have your brake system inspected right away.

When the ignition is on, the BRAKE light will come on when you set your parking brake. The light will stay on if your parking brake does not release fully. A chime will also sound if the parking brake is not fully released and the vehicle is moving. If it stays on after your parking brake is fully released, it means you have a brake problem.

The BRAKE light will also come on to indicate a low brake fluid level. See Brakes for more information.

If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push or the pedal may go closer to the floor. It may take longer to stop. Make sure the parking brake is fully released. Turn the ignition off and wait several seconds to restart vehicle, if the light is still on, have the vehicle towed for service. See Towing Your Vehicle .

Caution: 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.
