Cadillac 2007 Escalade - Manual (Page 227)

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 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.
When this light comes on, the DIC will also display
the SERVICE BATTERY NOT CHARGING
SYSTEM message. See DIC Warnings and
Messages on page 245 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.
