If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx


socket or T15 Torx screwdriver.Headlamp Horizontal Aiming
Turn the horizontal aiming screw (A) until the indicator
(B) is lined up with zero.
Once the horizontal aim is adjusted, then adjust the
vertical aim.

Headlamp Vertical Aiming
1. Find the aim dot on the lens of the lamps.
2. Measure the distance from the ground to the aim dot
on each lamp; if left low beam, subtract two inches.
Record this distance.3. At the wall or other flat surface, measure from the
floor to the recorded distance and draw a horizontal
line the width of the vehicle.

4. Turn on the low beam headlamps and cover the lamp
not being evaluated. The ambient light should allow
the beam cut off to be seen on the wall.5. Turn the vertical aiming screw (C) until the
headlamp beam is aimed to the horizontal line. It is
recommended to cover the lamp that is not being
evaluated to better see the beam being aimed.

Once the headlamp assembly has been removed from
the vehicle, the front turn signal bulbs can be accessed.
1. Reach down into the space provided by the removal
of the headlamp assembly and, while pushing in the
tab on the bulb assembly, turn the assembly
counterclockwise and remove it.
2. Remove the old bulb by pulling it straight out
of the retainer.
3. Replace the bulb and turn the bulb assembly
back into place.
Cornering Lamps
Follow the same procedure as used for replacing the
headlamps. However, to remove the cornering lamp
bulb, press the tab on the bulb assembly while turning
the bulb assembly counterclockwise. Pull the bulb
straight out. Replace the bulb and turn the bulb assembly
back into place.

6-49 Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
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.
See ªChanging a Flat Tireº in the Index for
more information.
