FORD 2013 F-150 v.2 - Manual (Page 338)

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.
Vertical Aim Adjustment
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
• (A) 8 feet (2.4 meters)
• (B) Center height of lamp to
ground
• (C) 25 feet (7.6 meters)
• (D) Horizontal reference line
2. Measure the height from the center of your headlamp (indicated by a
3.0 millimeter circle on the lens) to the ground and mark an 8 foot
(2.4 meter) horizontal reference line on the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light hits the wall.
For Vehicles With Halogen Headlamps:
On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam
will need to be adjusted so the edge
is at the same height as the
horizontal reference line.
