Brake System Light The warning light for the brakes can show two things - that the parking brake is not fully released, or that the brake fluid level is low in the master cylinder reservoir. If the fluid level is low, the brake system should be checked by a qualified service technician. WARNING If the anti-lock brake system warning light remains on or comes on while driving, have the braking system checked by a qualified service technician as soon as possible. This light comes on briefly when you turn the ignition key to ON, but it normally goes off shortly after the engine starts and you release the parking brake. If the light stays on or comes on after you have released the parking brake fully, have the hydraulic brake system serviced. 12
