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. 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 Driver Information Center (DIC) will also display the SERVICE BATTERY CHARGING SYSTEM message. See DIC Warnings and Messages on page 239 for more information. 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. Voltmeter Gage When the engine is not running, but the ignition is turned to ON, this gage shows the battery's state of charge in DC volts. When the engine is running, this gage shows the condition of the charging system. The vehicle's charging system regulates voltage based on the state of charge of the battery. The voltmeter may fluctuate. This is normal. Readings between the low and high warning zones indicate the normal operating range. 216
