Charging System Light This light comes on briefly when the ignition key is turned to start, but the engine is not running, as a check to show it is working. Brake System Warning Light The 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. If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner. United States Canada This light should come on briefly when the engine is started. If it does not come on then, have it fixed so it will be ready to warn if there is a problem. When the ignition is on, the brake system warning light also comes on when the parking brake is set. The light will stay on if the parking brake does not fully release. If it stays on after the parking brake is fully released, it means there is a brake problem. 3-34
