If the light comes on while you are driving and you have a LOW BRAKE FLUID message showing on the DIC, pull off the road and stop carefully. You may notice that the pedal is 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 359. Anti-Lock Brake System Warning Light With the Anti-Lock Brake System (ABS), this light will come on when your engine is started and may stay on for several seconds. That is normal. If the light stays on, turn the ignition off or if the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See "Service ABS" under DIC Warnings and Messages on page 206. The ABS warning light will come on briefly when you turn the ignition on. This is normal. If the light does not come on then, have it fixed so it will be ready to warn you if there is a problem. 193 {CAUTION: Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service.
