This light will come on briefly when you turn on the ignition, and the engine is not running, as a check to show it is working. Then it should go out when the engine is started.
If the light comes on and an Alternator message on the Driver Information Center (DIC) stays on, you may have a problem with the electrical charging system. Have it checked by your dealer/retailer.
Driving while this light is on could drain your battery.
If you must drive a short distance with the light on, be sure to turn off all accessories, such as the radio and air conditioner.
The Alternator message will remain until (Trip/Fuel) or (Enter) are pressed, but the light will remain until the problem is fixed. See DIC Warnings and Messagesfor more information.
