Headlamp aiming is done with the vehicle's
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
To adjust the vertical aim, do the following:
1. Open the hood. See Hood Release on
page 401 for more information.
3. Measure the distance from the ground to the
center of the projector lens of the low-beam
headlamp. Record the distance.
2. Locate the center
of the projector lens
of the low-beam
headlamp.
