{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the passenger’s
frontal airbag and side impact airbag
(if equipped), it means that something may
be wrong with the airbag system. The
passenger’s frontal airbag and side impact
airbag (if equipped) could inate even though
the switch is off. If this ever happens, do not
let anyone whom the national government has
identied as a member of a passenger airbag
risk group sit in the passenger’s position
(for example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 1-48.
Voltmeter Gage
The voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
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 BATTERY VOLTAGE
LOW 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.
