Headlamp Aiming
The aim of your vehicle's headlamps can be adjusted by
using aim tips located on the outer surface of the lens.
The aim has been pre
-set at the factory and should need
no further adjustment.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, it is recommended that
you take your vehicle to the dealer for assistance.

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 ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the instrument panel fuse block. An electrical overload
will cause the lamps to go on and off, or in some cases
to remain off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
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.

6-69 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. Spare fuses are located in the instrument
panel. See ªUnderhood Fuse Blockº in the Index.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 puller and a fuse usage chart.
To use the fuse puller, place the wide end of the fuse
puller over the plastic end of the fuse. Squeeze the ends
over the fuse and pull it out.
To reinstall the bin, position the lower end and turn
the top into position. Press on the sides until it snaps
into place.
