Voltmeter Gage - Chevrolet Corvette 2003 Owner's Manual

{
CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The passenger's air bag could inflate
even though the switch is off. If this ever
happens, don't let anyone whom the national
government has identified as a member of a
passenger air bag risk group sit in the
passenger's position (for example, don't
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
See "Air Bag Off Switch" in the Index.

Voltmeter Gage

The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and
disable your vehicle.
When the key is in ON
with the engine not
running, the voltmeter
shows the voltage output
of your battery. When
the engine is running, it
shows the voltage
output of the charging
system.
