Voltmeter Gage
When the engine is not
running, but the ignition
is 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.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating
in the vehicle and the engine is left idling for an
extended period.
If there is a problem with the battery charging system,
a SERVICE BATTERY CHARGING SYSTEM message
will appear in the Driver Information Center (DIC)
and/or the charging system light will come on. See DIC
Warnings and Messages on page 3-56 and Charging
System Light on page 3-39 for more information.
However, readings in either warning zone may indicate
a possible problem in the electrical system. Have
the vehicle serviced as soon as possible.
