Power Windows and Other Power
Options
Circuit breakers in the rear fuse block protect the power
windows and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is ®xed
or goes 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.
You will ®nd a fuse puller clipped in both of the fuse
blocks. Snap the wide end of the fuse puller at the side
indentations and pull the fuse out.
The MaxiFuses are located in two fuse blocks, one
located in the engine compartment on the passenger's
side and the other under the rear seat on the driver's
side. If a MaxiFuse should blow, have your vehicle
serviced by your dealer immediately.
Engine Compartment Fuse Block
The engine compartment
fuse block is located near
the front on the
passenger's side of the
vehicle. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
Lift the cover to gain access. On some vehicles, there
may be an additional cover that you will need to lift
to gain access to the fuses.
Fuse 22 or 23 can be moved to the outer position to
provide continuous power to the auxiliary outlets
or cigarette lighter when the ignition is not on. See your
dealer for additional assistance, if needed.

Removing the Rear Seat Cushion
Notice:The battery and main fuse blocks are
located under the rear seat cushion. The battery's
ground terminal and some relay wires are exposed.
To help avoid damage to the battery and wires,
be careful when removing or reinstalling the seat
cushion. Do not remove covers from covered parts.
Do not store anything under the seat, as objects
could touch exposed wires and cause a short.
To remove the rear seat cushion, do the following:
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, do the following:{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.
5-89

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.

The rear fuse block is
located beneath the rear
seat on the driver's
side. The rear seat cushion
must be removed to
access the fuse block. See

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
ªWindshield Wiper and Wiper Bladesº under
Cleaning
the Outside of Your Vehicle on page 5-80.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-23.
Automatic Transaxle Check
Check the transaxle ¯uid level; add if needed. SeeAutomatic Transaxle Fluid on page 5-21. A ¯uid loss
may indicate a problem. Check the system and repair if
needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
speci®ed in Part D.
Body Lubrication Service
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, glove box
door and console door. Part D tells you what to
use. More frequent lubrication may be required when
exposed to a corrosive environment.

{CAUTION:
When you are doing this check, the vehicle
could move suddenly. If it does, you or others
could be injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See
Parking Brake on page 2-27if
necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only in PARK (P) or NEUTRAL (N).
If the starter works in any other position, your
vehicle needs service.
Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this check, the vehicle
could move suddenly. If it does, you or others
could be injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. See
Parking Brake
on page 2-27if necessary.

the regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.
