ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are properly
aimed at the assembly plant. If your vehicle
has been in an accident, contact an
authorized dealer to check and realign your
headlamps.

1. Park your vehicle directly in front of a wall
or screen on a level surface,
approximately 25 ft (7.6 m) away.
2. Measure the height from the center of
your headlamp, indicated by a 3
millimeter circle on the lens, to the
ground and mark an 8 ft (2.4 m)
horizontal reference line on the vertical
wall or screen at this height, a piece of
masking tape works well.
3. Switch 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.

4. On the wall or screen, observe a light
pattern with a distinct horizontal edge
toward the right. If this edge is not at the
horizontal reference line, adjust the beam
so the edge is at the same height as the
horizontal reference line.
