RWARNING 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. NOTE: If a fault occurs in the anti-lock system, and the brake warning light is not lit, the anti-lock system is disabled but normal brake function remains operational. 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. 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. 85
