Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper service manual. It tells you
much more about how
to service your vehicle than this
manual can. To order the proper service manual,
see Service Publications Ordering information on
page 7-10.
Your vehicle has an air bag system. Before attempting
to do your own service work, see Servicing
Your Air
Bag-Equipped Vehicle on page 1-57.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See Part
E: Maintenance Record on page 6-16.
- --I can be jured and your v icle coul Be
damaged
if you try to do service work on a
vehicle without knowing enough about
it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If
you
use the wrong fasteners, parts can later
break or fall off.
You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside of
your vehicle.

Before closing the hood

filler caps are on properly. Then pull the
hood down
and close it firmly.

Electrical System
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
Servicing Your Air Bag-Equipped Vehicle on page
1-57.
Headlamp Wiring
The headlamp circuit is protected by individual fuses in
the underhood fuse block. An electrical overload will
cause the fuse to blow. If this happens, have your
headlamp system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and
a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.
Power Windows and Other Power
Options
Circuit breakers in the fuse panel 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 fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
greatly reduces the chance of fires 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. See Underhood Fuse Block later in
this section.

Instrument Panel Fuse Block
Some fuses are in a fuse block located inside of the
glove box behind a small bin on the right side.
To open,
pull the cover out. The fuse block is inside. On the
back edge of this cover is a fuse usage chart.
To reinstall the bin, position the lower end and turn the
top into position. Press on the sides until it snaps
into place.
