Position vehicle on a flat floor surface that meets the following (ISO 10640) specifications:

0.5mm or less slant from front wheel to back wheel of the Hella Universal Beamsetter IV VAS 5107 - A -.
1mm or less slant per meter for the length of the vehicle - B -.

Clean headlight lenses.
Adjust vehicle tire pressure to specifications.

Have a second technician sit in the drivers seat while aligning the headlights.

Bounce front and rear of vehicle up and down several times to settle vehicle suspension.

Setting low beam alignment of drivers side headlight

Move Hella Universal Beamsetter IV VAS 5107 into position in front of the vehicle so it is aligned with the vehicle and Hella Universal Beamsetter IV VAS 5107 is 30 to 70cm (12 to 28 in.) from the drivers side headlight.
Switch headlights ON in low beam position.
Align Hella Universal Beamsetter IV VAS 5107 so it is centered on the headlight (align vertically then horizontally).

NOTE:

Use the arrows on the Hella Universal Beamsetter IV VAS 5107 housing as a guide.
You may want to use a straight edge or tape measure, because alignment must be within 3cm (1.2 in.) of the center of the headlight.
Without moving the Hella Universal Beamsetter IV VAS 5107 , slide Broad-band sight toward center of vehicle (Broad-band sight can also be moved up and down for a better position).

Use Broad-band sight to make final alignment of Hella Universal Beamsetter IV VAS 5107 to vehicle by:

Loosening hand-wheel that locks column in place.
Sighting down through the slit in the Broad-band sight and rotating Hella Universal Beamsetter IV VAS 5107 and column until two similar points on vehicle are aligned

NOTE:

Try using corners of the headlight housings or two screws that are the same height and as far apart as possible on the vehicle.
Carefully tighten hand wheel without changing Hella Universal Beamsetter IV VAS 5107 position.
Set Inclination to 1.0 %.
Set Hella Universal Beamsetter IV VAS 5107 "Scaled wheel" to the proper low beam inclination %.
Adjust height (vertical) alignment first. Turn headlight height adjuster screw to align the upper edge of the flat portion of the beam with the center horizontal line of the grid on the Hella Universal Beamsetter IV VAS 5107 pattern screen.

NOTE:

VOL is the correct beam pattern for both right and left headlights.

Adjust lateral (horizontal) alignment of drivers side headlight so that the peak (highest point) of the headlight beam pattern aligns with the right edge of the target box of the grid on the pattern screen (it should match the VOL pattern shown on the Hella Universal Beamsetter IV VAS 5107 ).

NOTE:

If the height alignment changed, readjust.

Checking drivers side headlight high beam alignment

Switch headlights ON in high beam position.
Realign Hella Universal Beamsetter IV VAS 5107 with the high beam headlight if necessary.

Set Beamsetter "Scaled wheel" to 0%.
Cover low beam lamp (use hand or small piece of cardboard) and check that the "hot spot" of high beam pattern is centered on the square target box of the pattern screen.

NOTE:

High beam pattern is built into the reflector design and cannot be adjusted separately.

If high beam pattern is way out of adjustment:

Inspect for reflector damage.
Replace reflector if needed.

NOTE:

Always align headlight in the low beam position.

Aligning fog lamp

Switch fog lamps ON.
Align Hella Universal Beamsetter IV VAS 5107 with fog lamp (make sure it is between 30 and 70cm from the fog lamp lens).

Set Hella Universal Beamsetter IV VAS 5107 scaled wheel to 1.4%.

Adjust fog lamp so the top of the beam pattern aligns with the centerline of the target grid on the beam pattern screen.

Passengers side headlight, alignment

Move Hella Universal Beamsetter IV VAS 5107 to the passenger side of the vehicle and follow the same procedures to align the Hella Universal Beamsetter IV VAS 5107 to the headlamp.
Align headlight low beam, check high beam and align fog lamp.

NOTE:

Make sure to reset the Hella Universal Beamsetter IV VAS 5107 "Scaled wheel" to the proper setting each time you change from low beam to high beam or to fog lamp.
Ensure that headlights and vehicle body are clean and free of fingerprints.
