headlamp BUICK LESABRE 2005 Owner's Guide

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 located 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
To adjust the horizontal aim, do the following:
1. Open the hood. SeeHood Release on page 5-11
for more information.
2. Locate the horizontal aiming screw (A).
3. 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 rst will result in an
incorrect headlamp aim.
To adjust the vertical aim, do the following:
1. Follow the steps listed underHeadlamp
Horizontal Aiming on page 5-46rst before
adjusting the vertical aim if horizontal aiming needs
to be performed.
2. Find the aim dot on the lens of the
low-beam lamps.
3. Measure the distance from the ground to the aim
dot on each lamp; if left low beam, subtract
2 inches (5 cm). Record this distance.4. At the wall or other at surface, measure from the
ground upward the recorded distance from Step 3
and draw or tape a horizontal line the width of
the vehicle.
5. Turn on the low-beam headlamps.
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. 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 at surface.
5-47

7. Turn the vertical aiming
screw (C) until the
headlamp beam
is aimed to the
horizontal tape line.
The top edge of the cut-off should be positioned at
the bottom edge of the horizontal tape line.
8. Repeat the steps for the opposite headlamp.Bulb Replacement

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 5-70for
more information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class “S” type chains
that are the proper size for your tires. Install them
on the front tires and tighten them as tightly as
possible with the ends securely fastened. Drive
slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the contact
continues, slow down until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.
