Safety Belt Reminder Light
When the key is turned to RUN, a chime will come
on for several seconds to remind people to fasten
their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will ash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Airbag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks
the air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the air bag system,
seeAirbag System on page 1-49.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then
the light should go out.
This means the system
is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without — like the radio or
cigarette lighter— and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Main Instrument Panel Fuse Block
The main instrument panel fuse block is located
under the instrument panel, on the passenger’s side of
the vehicle. Lamps, connectors and the HVAC duct
temperature sensors may need to be disconnected and
removed to allow access to this fuse block.
Remove the hush panel on the passenger’s side to
reveal the fuses by performing the following steps:
1. Remove the two screws located along the front
edge of the panel.
2. Lower the hush panel.
3. Remove the fuse block cover.
4. Place the wide end of the fuse puller over the
plastic end of the fuse.
5. Squeeze the ends over the fuse and pull it out.
When nished, reinstall the fuse block cover and
the hush panel. Reinstall lamps, connectors and HVAC
duct temperature sensors if they were removed.
