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.
Air Bag 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,
see
Air Bag Systems on page 1-48.
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.

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 damage
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.
There are four fuse blocks in your vehicle: the main and
auxiliary instrument panel fuse blocks, the underhood
fuse block and the rear fuse block.
Main and Auxiliary Instrument Panel
Fuse Blocks
The main and auxiliary instrument panel fuse blocks are
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 these
fuse blocks.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.
