LINCOLN TOWN CAR 2002 Workshop Manual

AIMING THE HEADLAMPS
Your vehicle is equipped with a Vehicle Headlamp Aim Device (VHAD)
on each headlamp. Each headlamp may be properly aimed in the vertical
(up/down) and the horizontal (left/right) directions using your VHAD
system. The headlamps on your vehicle are properly aimed at the
assembly plant.
A bubble (vertical indicator) that is not centered between the two red
lines does not necessarily indicate out-of-aim headlamps. If your vehicle
is not positioned on a level surface, the slope will be included in the
vertical indication. Therefore, vertical and horizontal headlamp
adjustment should be performed only when the beam direction appears
to be incorrect.
You will need one 4 mm wrench or socket to make the adjustments.
If the vehicle has been in an accident, the vehicle's front structure
should be properly aligned before aiming the headlamps.
Horizontal aim adjustment
1. Park the vehicle on a level
surface.
2. With the hood open, remove the
protective cover, then locate the
horizontal indicator and the
adjusting screw at the rear of the
headlamp assembly.
3.Usea4mmwrench or socket to
turn the horizontal adjusting screw
until the ª0º mark on the yellow dial
lines up with the reference mark on
the marker (as shown) when viewed
directly from above.

Turning the horizontal adjusting
screw in the direction of the arrow
changes the horizontal aim as
shown.
Vertical aim adjustment
1. Park the vehicle on a level
surface.
2. With the hood open, remove
protective cover, then locate the
bubble level and the vertical
adjustment screw. The adjustment
screw is located on the outboard
side of the headlamp.
3. The ªUº and ªDº on the bubble
indicate the directional change (up
or down) of the vertical aim.
4.Usea4mmwrench or socket to
turn the vertical adjusting screw
until the bubble is centered between
the two red lines which represents
the ª0º mark position.
5. Install protective cover.
When the horizontal and vertical indicators are set to the ª0º mark, the
headlamp has been properly aimed.

Do not remove lamp bulbs unless they will be replaced immediately. If a
bulb is removed for an extended period of time, contaminants may enter
the lamp housings and affect performance.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized ªD.O.T.º for North America and an
ªEº for Europe to assure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.

bulb left or right to align the grooves in the plastic base with the tabs in
the lamp assembly. When the grooves are aligned, push the bulb into the
lamp assembly until the plastic base contacts the rear of the lamp
assembly.
2. Install the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating it clockwise until you feel a ªstop.º

If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
