When the ignition is on, the brake system warning light will also come 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 the vehicle has a brake problem.

See DIC Warnings and Messages on page 3-67 for more information. The brake warning light may also come on when the brake fluid is low. If this occurs, the LOW BRAKE FLUID message will also appear in the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-67 for more information.
