AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp. Each
headlamp may be properly aimed in
the vertical (up/down) and the
horizontal (left/right) directions
using your VHAD system. The
headlamps on your vehicle are
properly aimed at the assembly
plant.
A bubble (vertical indicator) that is
not centered between the two red
lines 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 vertical indication. Therefore, vertical
and horizontal headlamp adjustment should be performed only when the
beam direction appears to be incorrect.
You will need one 4 mm wrench or socket to make the adjustments.
If the vehicle has been in an accident, the vehicle’s front structure
should be properly aligned before aiming the headlamps.
Horizontal aim adjustment
1.
Park the vehicle on a level surface.
2. With the hood open, locate the
horizontal indicator and the
adjusting screw. They are located
below the viewing hole at the rear
of the headlamp assembly.
3.Usea4mmwrench or socket to
turn the horizontal adjusting screw
until the “0” mark on the yellow dial
lines up with the reference mark on
the marker (as shown) when viewed directly from above.
