Aiming The Headlamps - Ford Explorer 1998 Owner's Manual

Maintenance and care

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
D
horizontal (left/right) directions
U
using your VHAD system. The
headlamps on your vehicle are
properly aimed at the assembly
plant, and vertical and horizontal
indicators of the VHAD system are
calibrated.
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 with ratchet to make the
adjustments.
The following procedure assumes that the factory set horizontal indicator
reference has not changed and the vehicle's front structure is in its
factory alignment condition. If the vehicle has been in an accident
requiring the front end of the vehicle to be repaired, the horizontal
indicator should be recalibrated by the servicing facility according to
instructions in the vehicle's Workshop Manual.
