3-34 Instrument Panel This light should come on briefly when the ignition key is turned to ON/RUN. If it does not come on then, have it fixed so it will be ready to warn if there is a problem. This light may also come on due to low brake fluid. See Brakes on page 5-26 for more information. 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 there is a brake problem. If the light comes on while driving, pull off the road and stop carefully. Make sure the parking brake is fully released. The pedal may be harder to push or, the pedal may go closer to the floor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-20. Brake System Warning Light This vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking both parts need to be working. If the warning light comes on, there is a brake problem. Have the brake system inspected right away. { 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.
