{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 in¯ate
even though the switch is off. If this ever
happens, don't let anyone whom the national
government has identi®ed 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 ªAir Bag Off Switchº in the Index.
Voltmeter Gage
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.
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.

Security Light
This light comes on to
remind you to arm your
theft-deterrent system. If it
comes on and stays on
when your ignition is

This light will come on
brie¯y when you are
starting the engine. If the
light comes on and
stays on while you are
driving, check your gages
to see if they are in the

·Low Oil Pressure
·High Coolant Temperature
·High or Low Battery Voltage
·Low Fuel Level
Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is on.
When the needle approaches the red zone, RESERVE
FUEL will appear on the Driver Information Center (DIC)
display. When the needle approaches the E, LOW
FUEL will appear on the display. At this time, you still
have a little fuel left, but you should get more soon.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
