8. Slide the lamp assembly back into place by lining
up the track on the bottom of the assembly with the
guide on the vehicle.
9. Then connect the outboard snap mounting pin.
10. Secure the lamp assembly with the two bolts.Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators. The
aim has been preset at the factory and should need no
further adjustment. This is true even though your
horizontal aim indicators may not fall exactly on the ª0º
(zero) marks on their scales.
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, we recommend that you
take your vehicle to your dealer for service. However, it
is possible for you to re
-aim your headlamps as
described in the following procedure.

NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
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 or other
flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat surface.

The vehicle should not have any snow, ice or mud
attached to 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 inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
The headlamp aiming devices are under the hood near
the headlamps.
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
NOTICE:
Horizontal aiming must be performed before
making any adjustments to the vertical aim.
Adjusting the vertical aim first will result in an
incorrect headlamp aim.
1. Find the aim dot on the lens of the low beam 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
ground upward the recorded distance from step 2 and
draw or tape a horizontal line the width of the vehicle.

4. Turn on the low-beam headlamps and place a piece
of cardboard or equivalent in front of the headlamp
not being aimed. This should allow only the beam of
light from the headlamp being aimed to be seen on
the flat surface.
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.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Oldsmobile Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.
CAUTION: (Continued)
CAUTION: (Continued)

Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.

Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.

Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
