How to adjust the headlamp height, I think my lights are aiming to high. Cheers

Owner's manual says high beams will be adjusted by correctly adjusting the low beam.

I took my car to my mechanics and he had the equipment to set my lights. Better that way if you do not know what you are doing.

Headlamp Adjustment —Screen Method Aiming NOTE: Horizontal aim is not necessary for this vehicle and is not adjustable.
NOTE: Consult your state's vehicle inspection manual for recommended tolerance ranges for visual aiming.

1. NOTE: The sight shield may need to be positioned or removed for access to the adjusters.
   Before starting headlamp assembly adjustment:
• Check the tire inflation.
• Check that no other load is in the vehicle other than a half tank of gas.
• Check that the headlamps are clean.
• Check for correct headlamp operation.
• Check that the vehicle is on level ground.
• If the vehicle is equipped with air suspension, make sure the switch is on.
• NOTE: The vertical wall or screen must be a minimum of 2.4 meters (8 feet) wide.
2. Park the vehicle on a level surface approximately 7.6 meters (25 feet) from the vertical wall or screen directly in front of it.

NOTE: The center of the lamp is marked by a 3 mm (0.12 in) circle on the headlamp lens.
Mark a horizontal reference line on the vertical wall or screen.
1. Measure the center of the headlamp height to ground and record.
1. Make a 2.4 meters (8 feet) horizontal mark (masking tape) on the vertical wall or screen at the same distance from the ground as previously recorded.

1. NOTE: This procedure should be done in a dark environment to effectively see the headlamp beam pattern.
   Turn on the low beam headlamps to illuminate the wall or screen and open the hood.

1. NOTE: The appearance of the beam pattern may vary between vehicles.
   On the wall or screen, locate the high intensity area of the beam pattern.

NOTE: The appearance of the beam pattern may vary between vehicles.
Identify at the top edge of this high intensity area a distinct horizontal cutoff in the beam pattern. If the top edge of this cutoff is not even with the horizontal reference line, the headlamp beam will need to be adjusted.

VERTICAL AIM ADJUSTMENT
1. Park the vehicle on a level surface approximately 7.6 meters (25 feet)
from a vertical wall or screen directly in front of it.

2. Measure the height from the
center of your headlamp to the
ground and mark a 2.4 meter (8
foot) horizontal reference line on
the vertical wall or screen at this
height (a piece of masking tape
works well). The center of the lamp
is marked by a 3.0 mm circle on the
headlamp lens.

3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.

4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge of high
intensity light with a slight angle
towards the right. If this edge is not
at the horizontal reference line, the
beam will need to be adjusted.

5. Locate the vertical adjuster on
each headlamp, then use a 4 mm
socket/wrench to turn the adjuster
either counterclockwise (to adjust
down) or clockwise (to adjust up)
aligning the upper edge of the light
pattern up to the horizontal line
.
6. HORIZONTAL AIM IS NOT
REQUIRED FOR THIS VEHICLE
AND IS NON-ADJUSTABLE.

Hello...

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
