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 a
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 Driver Information
Center (DIC) will also display the SERVICE
BATTERY CHARGING SYSTEM message. See
DIC Warnings and Messages on page 239
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.
Voltmeter Gage
When the engine is not
running, but the ignition
is turned to ON, this
gage shows the
battery’s state of charge
in DC volts.
When the engine is running, this gage shows the
condition of the charging system. The vehicle’s
charging system regulates voltage based on
the state of charge of the battery. The voltmeter
may fluctuate. This is normal. Readings between
the low and high warning zones indicate the
normal operating range.
