AIMING 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 a qualified
service technician.
Headlamp vertical aim adjustment
1. Park the vehicle on a level surface approximately
7.6 meters (25 feet) from a vertical wall or screen
directly in front of it.
•(1) Eight feet
•(2) Center height of lamp to ground
•(3) Twenty five feet
•(4) Horizontal
reference line
2. Measure the height
from the center of your
headlamp to the
ground and mark a 2.4
meter (8 foot)
horizontal reference
line on the vertical wall or screen at this height (a
piece of masking tape works well). The center of the
lamp is marked by a 3.0 mm circle on the headlamp
lens.
3. Turn on the low beam headlamps to illuminate the
wall or screen and open the hood.
4. On the wall or
screen you will observe
a light pattern with flat
edges at the top of the
beam pattern. If the
flat edges are not at
the horizontal
reference line, the beam will need to be adjusted.
