Doing Your Own Service Work
{CAUTION:
You can be injured and your vehicle could
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.If you want to do some of your own service work,
you should 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, seeService Publications
Ordering Information on page 600.
Your vehicle has an airbag system. Before
attempting to do your own service work, see
Servicing Your Airbag-Equipped Vehicle
on page 86.
You should keep a record with all parts receipts
and list the mileage and the date of any service
work you perform. SeeMaintenance Record
on page 578.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s
battery, even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 86.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal 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 and not snow,
etc., be sure to get it xed.
Power Windows and Other
Power Options
Circuit breakers protect the power windows and
other power accessories. If the current load
is too heavy, the circuit breaker opens and then
closes after a cool down period, protecting
the circuit until the problem is xed or goes away.
547

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.
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.
