If, after several seconds, all status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer for service. Charging System Light The charging system light will come on briefly when you turn on the ignition, but the engine is not running, as a check to show you it is working. {CAUTION: If the off indicator and the air bag readiness light ever come on together, it means that something may be wrong with the air bag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger seat may not have the protection of the frontal air bag. See "Air Bag Readiness Light" in the Index. It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. It could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. Driving while this light is on could drain your battery. When this light comes on the DIC will also display the battery not charging message. See DIC Warnings and Messages on page 3-57. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner. 3-36
