the recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) the width of the
vehicle at the wall where it was marked in Step 4.
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.
6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent 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.
7. Locate the vertical headlamp aiming screws.
They are located under the hood near each
headlamp assembly. First lift the flap to access
either of them. Each one is the top outboard
screw by the V on the cover panel next to the
aiming flap.
The adjustment screw can be turned with a
6 mm hex wrench.
