Maintenance and care
173 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
and a level surface can be verified. AIMING THE HEADLAMPS
The alignment of your headlamps
should be checked if:
•Oncoming motorists frequently
signal you to deactivate your high
beams, and your high beams are
not activated.
•The headlamps do not seem to
provide enough light for clear
night vision.
•The headlamp beams are pointed
substantially away from a slightly
down and to the right position.

Adjusting the horizontal aim
1. Make sure the vehicle is on a
level surface.
2.With the hood open, locate the
horizontal indicator and adjusting
screw.
3. Turn the horizontal adjusting
screw until the reference mark on
the reflector extension aligns with
the “0” reference mark on the
horizontal indicator when viewed
directly from above.
4. When the horizontal aim has
been adjusted, close the headlamp
access panel. The horizontal aim must be
adjusted first. You will need one 7
mm box wrench, open end wrench
or T-15 Torx drive.
The following procedures assumes
that the vehicle’s front structure is
properly aligned. If the vehicle has
been in an accident requiring the
front end of the vehicle to be
repaired, the horizontal indicator
should be recalibrated by your
dealer or a qualified service
technician.

Adjusting the vertical aim
The numbers shown on the vial
indicate beam direction in degrees
up or down.
1. Do not adjust the vertical aim
until after adjusting the horizontal
aim.
2. With the hood open, locate the
bubble level vertical aim indicator.
It is visible when viewed from the
above rear of the headlamp.
3. Turn the vertical adjusting screw
until the reference mark on the
reflector extension aligns with the
“0” reference mark on the vertical
indicator when viewed from
directly above.
4. Close the hood.
