When reassembling the lamp, make sure to align the

to the plastic retainer at the outboard edge of
the vehicle.Headlamp Aiming
The headlamp aiming device is under the hood, directly
behind the headlamps.
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre
-set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on the
ª0º (zero) marks on their scales.

6-38
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment may be necessary
if it is difficult to see lane markers (for horizontal aim),
or if oncoming drivers flash their high beams at you
(for vertical aim). If you believe your headlamps need to
be re
-aimed, we recommend that you take it to your
dealer for service; however, it is possible for you to
re
-aim your headlamps as described in the
following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
To check the aim, the vehicle should be properly
prepared as follows:

The vehicle must have all four tires on a perfectly
level surface.

If necessary, pads may be used on an uneven surface.

The vehicle should not have any snow, ice or mud
attached to it.

The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

There should not be any cargo or loading of the
vehicle, except it should have a full tank of fuel and
one person or 160 lbs. (75 kg) on the driver's seat.

Close all doors.

Tires should be properly inflated.

Rock the vehicle to stabilize the suspension.
Start with the horizontal aim. The adjustment screws
can be turned with an E8 Torx
 socket or
T15 Torx screwdriver.
Once the horizontal aim is adjusted, then adjust the
vertical aim.

6-39
1. Turn the horizontal
aiming screw (A)
until the
indicator (B) is
lined up with zero.
2. Turn the vertical aiming screw (C) until the level
bubble (D) is lined up with zero.
