Charging System Light - Chevrolet 2007 Avalanche Owner's Manual

Charging System Light

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 the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your
battery.
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.
When this light comes on, the DIC will also display
the SERVICE BATTERY NOT CHARGING
SYSTEM message. See DIC Warnings and
Messages on page 269 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, to reduce
the drain on your battery.
