AIMING THE HEADLAMPS
Your vehicle is equipped with a Vehicle Headlamp Aim Device (VHAD)
on each headlamp body. Each headlamp may be properly aimed in the
horizontal direction (left/right) and the vertical position (up/down).
A non-zero bubble reading does not necessarily indicate out-of-aim
headlamps. If your vehicle is not positioned on a level surface, the slope
will be included in the level indicator. Therefore, vertical headlamp
adjustment should be performed only when beam direction appears to be
incorrect or a level surface can not be verified.
The horizontal aim must be adjusted first. You will need one 4 mm box
wrench or open end wrench.
