Headlamp Aiming - Ford 2001 Mercury Cougar Owner's Manual

Maintenance and care

Headlamp aiming

• Your vehicle is equipped with
headlamps designed to meet Visual
aim requirements according to
FMVSS 108, table 17 2.
• Your headlamps are marked VOL
[visual/optical (aiming) left]. This
means that the left side of the light
patterns for each low beam
headlamp is used to aim the lamp
(Fig. 1).
• Each headlamp may be properly
aimed in the vertical (up/down)
direction only. The horizontal
(left/right) aim is preset by the
headlamp manufacturer and does
not need to be re aimed.
• Turning the headlamp adjusting
screws V1 and V2 in the directions
indicated by the embedded arrows
(Fig. 2) represents a change in
vertical aim direction. Turn
clockwise for up and counter
clockwise for down. It is important
that both adjusting screws are
turned by an equal number of
revolutions or parts of revolutions
and are turned as well in the same
direction. Turn V1 before V2. Never
V2 before V1. Failing this
requirement leads to
improperly aimed headlamps
and may cause glare light for
oncoming drivers. For example, if
one of your low beam headlamps is
aimed too low, you will turn V1 and
V2 clockwise an equal number of
revolutions until correct aim is
achieved.
