Charging System Light - GMC 2008 Envoy Denali Owner's Manual

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may
be a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
CAUTION:
{
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger's seat may not have the protection
of the airbag(s). See Airbag Readiness Light
on page 3-33 for more on this, including
important safety information.

Charging System Light

It should go out once the engine is running. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system Driver
Information Center (DIC) message may also appear.
See DIC Warnings and Messages on page 3-53 for
more information. This light could indicate that there
are problems with a generator drive belt, or that there is
an electrical problem. Have it checked right away. If you
must drive a short distance with the light on, be certain
to turn off all the accessories, such as the radio and air
conditioner.
This light will come on
briefly when you turn on the
ignition key, but the engine
is not running, as a check
to show you it is working.
