To disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the positive (+) terminal cover to its
original position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory
and should need no further adjustment
However, If the vehicle is damaged in an accident,
the headlamp aim may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high beams at
you, this may also mean the vertical aim needs to
be adjusted.It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
re-aimed. It is possible however, to re-aim the
headlamps as described in the following procedure.
The vehicle should be properly prepared as
follows:
The vehicle should be placed so the
headlamps are 25 ft. (7.6 m) from a light
colored wall.
The vehicle must have all four tires on a
perfectly level surface which is level all
the way to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) on the driver’s seat.
Tires should be properly inated.

Headlamp aiming is done with the vehicle’s
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
The vertical headlamp aiming screws are located
under the hood near the headlamps.
The adjustment screw can be turned with a 6 mm
socket wrench.To adjust the vertical aim on the headlamps, do
the following:
1. Open the hood. SeeHood Release on
page 277for more information.
2. Locate the aim dot on the lens of the
low-beam headlamp.
3. Measure the distance from the ground to the
aim dot on the low-beam headlamp. Record
the distance.
310

4. At the wall measure from the ground
upward (A) to the recorded distance
from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall
the width of the vehicle at the height of the
mark in Step 4.
Notice:Do not cover a headlamp to improve
beam cut-off when aiming. Covering a
headlamp may cause excessive heat build-up
which may cause damage to the headlamp.6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being adjusted. Do not place
directly on the headlamp. This allows only the
beam of light from the headlamp being
adjusted to be seen on the at surface.
7. Locate the vertical headlamp aiming screws,
which are under the hood near each headlamp
assembly.
The adjustment screw can be turned with a
6 mm socket wrench.
8. Turn the vertical aiming screw until the
headlamp beam is aimed to the horizontal tape
line. Turn it clockwise or counterclockwise to
raise or lower the angle of the beam.
311

9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal
tape line. The lamp on the left (A) shows
the correct headlamp aim. The lamp on the
right (B) shows the incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite
headlamp.

7. To replace a headlamp bulb, do the following:
7.1. Disconnect the wiring harness from the
bulb socket.
7.2. Remove the black retainer by turning it
counterclockwise.8. Turn the bulb socket for the headlamp, front
turn signal, or parking lamp counterclockwise.
For the sidemarker bulb, you will need to
use a tool to assist in turning the bulb socket.
9. Pull the old bulb out of the socket.
10. Install a new bulb.
11. Reinstall the bulb assembly by reversing
Steps 1 through 8.
When reinstalling the headlamp assembly,
rst make sure that the wiring harness is
in its original position. If not, the headlamp
assembly will not t correctly.
You will also need to line up the two tabs
on the bottom of the assembly that t into

Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks air, replace
it (except some aluminum wheels, which can
sometimes be repaired). See your dealer if any
of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same
load-carrying capacity, diameter, width, offset and
be mounted the same way as the one it replaces.
If you need to replace any of your wheels, wheel
bolts, or wheel nuts, replace them only with new
GM original equipment parts. This way, you will be
sure to have the right wheel, wheel bolts, and wheel
nuts for your vehicle.{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision
in which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.
Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration, headlamp
aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.
SeeChanging a Flat Tire on page 338for more
information.

Headlamp Wiring
The headlamp wiring is protected by fuses.
Should your headlamps fail to function, 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 or ice, the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, have it xed.
Power Windows and Other Power
Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is xed.
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 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.
If you ever have a problem on the road and do not
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.
There are two fuse blocks in your vehicle: the oor
console fuse block and the engine compartment
fuse block.
There is one additional fuse located in the back of
the vehicle near the battery.
