Charging System Light The charging system light will come on for a few seconds when you turn on the ignition as a check to indicate it is working. If the light stays on, or comes on while you are driving and you hear a chime, there could be a problem with the electrical charging system. This could indicate that there is a loose generator drive belt or another electrical problem. Have it checked right away. Driving while this light is on could drain the battery and result in the engine and headlights suddenly shutting off. If you must drive a short distance with this light on, turn off accessories, such as the radio, air conditioner and heater fan. Brake System Warning Light Your vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on, there is a brake problem. Have your brake system inspected right away. United States Canada This light should come on briefly when you turn the ignition key to ON. If it does not come on then, have it fixed so it will be ready to warn you if there is a problem. 207
