To properly prepare the vehicle for vertical headlamp aiming, see
Headlamp Aiming
for more information.
Notice: Horizontal aiming must be performed before making any adjustments to
the vertical aim. Adjusting the vertical aim first will result in an incorrect
headlamp aim.
To adjust the vertical aim:
- Open the hood. See
Hood Release
for
more information.
- Locate the aim dot on the inner projector lens of the low-beam headlamp.
- Measure the distance from the ground to the aim dot on each low-beam headlamp.
Record this distance.
- At the wall or other flat surface, measure
from the ground upward (A) to the recorded distance from Step 3 and
mark it.
Notice: Do not cover a headlamp to improve beam cut-off when aiming. Covering
a headlamp may cause excessive heat build-up which may cause damage to the
headlamp.
- Draw or tape a horizontal line (B) on the wall or flat surface
the width of the vehicle at the height of the mark in Step 4.
- Turn on the low-beam headlamps and place a piece of cardboard in front
of the headlamp not being aimed. This should allow only the beam of light from the
headlamp being aimed to be seen on the flat surface.
- Locate the vertical headlamp aiming screws, which are under the hood near
each headlamp assembly.
The adjustment screw can be turned with a 6 mm
male hex.
- Turn the vertical aiming screw until the
headlamp beam is aimed to the horizontal tape line.
- The top edge of the cut-off should be positioned at the bottom edge of
the horizontal tape line.
- Make sure that the light from the headlamp
is positioned at the bottom edge of the horizontal tape line. The lamp on the left (A)
shows the correct headlamp aim. The lamp on the right (B) shows the incorrect
headlamp aim.
- Repeat Steps 7 through 9 for the opposite headlamp.
