Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-on electrical equipment can
keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
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 three fuse blocks in your vehicle: the
instrument panel fuse block located under the instrument
panel, the underhood fuse block located on the
passenger's side engine compartment and the rear fuse
block, located under the rear seat.

Removing the Rear Seat Cushion
NOTICE:
A fuse center is located under the rear seat
cushion. To help avoid damage to the fuse center,
be careful when removing or reinstalling the
seat cushion.
To Remove the Rear Seat Cushion
1. Pull up on the front of the cushion to release the
front hooks.
2. Pull the cushion up and out toward the front
of the vehicle.To Reinstall the Rear Seat Cushion

6-73
CAUTION:
A safety belt that isn't properly routed through
the seat cushion or is twisted won't provide the
protection needed in a crash. If the safety belt
hasn't been routed through the seat cushion at
all, it won't be there to work for the next
passenger. The person sitting in that position
could be badly injured. After reinstalling the seat
cushion, always check to be sure that the safety
belts are properly routed and are not twisted.
1. Buckle the center passenger position safety belt, then
route the safety belts through the proper slots in the
seat cushion. Don't let the safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear locating guides hook into the
wire loops on the back frame.
3. With the seat cushion lowered, push rearward and
then press down on the seat cushion until the spring
locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.
