Charging System Light
This light comes on briefly when
the ignition key is turned to START,
but the engine is not running, as a
check to show it is working.
If it does not, have the vehicle
serviced by your dealer.
The light should go out once
the engine starts. If it stays on,
or comes on while driving, there
could be a problem with the
charging system. A charging
system message in the Driver
Information Center (DIC) can also
appear. See Battery Voltage and
Charging Messages on page 5‑31
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 the vehicle
must be driven a short distance with
the light on, turn off accessories,
such as the radio and air
conditioner.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.

This light should come on when the
