Brake System Warning Light

The vehicle brake system consists of two hydraulic circuits. If one circuit is not working, the remaining circuit can still work to stop the vehicle. For normal braking performance, both circuits need to be working If the warning light comes on, there is a brake problem. Have the brake system inspected right away.

This light should come on briefly

This light should come on briefly when the ignition is placed in ON/RUN. 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 flashes or stays on if the parking brake is not fully released.

If the light stays on after the parking brake is fully released, there is a base brake problem.

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.

For vehicles with the Electric Parking Brake (EPB), this red brake status light comes on when the parking brake is applied. If the light continues flashing after the parking brake is released, or while driving, there is a problem with the Electric Parking Brake system.

If the light does not come on, or remains flashing, see your dealer.
