ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, an authorized dealer should
check the alignment of your headlamps.
Vertical Aim Adjustment
Before aim adjustment, disable the air suspension system. Refer to
Message center
in the
Driver Controls
chapter.
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 from that lamp
hits the wall.
4. 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.
