items such as liquids or sharp objects that could
damage, puncture or cut the trunk±mounted
CD changer or wiring.

damage the underbody.
Convenience Net
If your vehicle has this feature you will see it on the
back wall of the rear area of the vehicle.

larger, heavier loads.
You can unhook the net and place it in one of the rear
storage compartments when you are not using it.
On coupe models only, a vinyl storage bag has also
been provided.
Cargo Cover
If your vehicle has this feature, the security shade can
provide hidden storage in the rear area of the vehicle.
The shade is also helpful in blocking the glare from the
removable roof when it is stored in the rear
compartment.
Using the Cargo Cover
1. Hook the elastic loops
on the front corners (A)
of the shade to the
T-nuts located on the
front corners of the rear
hatch frame.

{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.
