Charging System Light - GMC TopKick 2007 Owner's Manual

CAUTION:
{
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger's airbag could inflate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identified as a
member of a passenger airbag risk group
sit in the right front passenger's position
(for example, do not secure a rear-facing
child restraint in the right front
passenger's seat) until you have your
vehicle serviced. See Airbag Off Switch on
page 76 and Airbag Readiness Light on
page 163 for more on this, including
important safety information.

Charging System Light

It should come on briefly when you turn on the
ignition, before the engine is running, as a check to
show that it is working.
If it stays on, or comes on while you are driving,
have your vehicle checked right away. You
could have a loose generator drive belt or some
other problem.
Driving while this light is on will drain your battery.
If you must drive a short distance with the light
on, turn off your radio and other accessories.
Sustained driving with a generator failure could
result in a lack of back-up braking if the engine
quits or the power steering pump should fail.
The charging system
light may be located in
the instrument panel
cluster, or with the
auxiliary warning lights
in the center of the
instrument panel.
