The charging system light comes on briefly when the ignition is turned on, but the engine is not running, as a check to show the light is working.

It should go out when the engine is started.

If the light stays on, or comes on while driving, there may be a problem with the electrical charging system. Have it checked by your dealer. Driving while this light is on could drain the battery.

When this light comes on, the Driver Information Center (DIC) also displays the SERVICE BATTERY CHARGING SYSTEM message.

See Vehicle Messages on page 5‑37 for more information.

If a short distance must be driven with the light on, be sure to turn off all accessories, such as the radio and air conditioner.
