Checking headlight adjustment (VW Caddy 3)

Conditions for checking and adjustment:

• The tire pressure is correct.
• Diffusers must not be dirty or damaged.
• The reflectors and headlight bulbs must be in good working order.
• The vehicle must be loaded. Load: One passenger or 75 kg per driver's seat in an unladen vehicle (curb weight).

The curb weight is the weight of a vehicle ready for operation with a fully filled fuel tank (at least 90% fuel), equipped with all the necessary operating equipment and devices (for example, a spare tire, a tool kit, a jack, a fire extinguisher, etc.).

If the fuel tank is not at least 90% full, then the load must be performed as follows.

Determine the weight of the additional load using the table, depending on the fuel level indicator in the tank. Additional cargo must be placed in the luggage compartment.

Fuel level indicator readings	Ballast weight, kg
Full	0
1/4	30
1/2	20
3/4	10

It is best to use water canisters as ballast (A 5-liter canister of water weighs approximately 5 kg).

In order for the body to settle at a level corresponding to the weight, it is necessary to roll the car for several meters or rock it up and down several times from the front and rear.

The vehicle and the headlight alignment tester must be installed on the same horizontal surface.

The vehicle and the headlight alignment tester must be aligned with each other.



The headlight aiming angle must be set to the nominal value.

The nominal tilt angle value is indicated as a percentage on the plate above the headlight. The headlight inclination must be adjusted according to this value.

The specified headlight inclination (in %) is determined by the ratio of the headlight inclination value to the base distance at which this value is measured (the base distance is 10 m).

Conversion example: 1.0% equals 10 cm.

The headlight range control must be set to the "O" position.

Checking the main headlights

The following is checked. With the low beam on, does the horizontal border of light and shadow touch the dividing strip (1) of the measuring screen and is the inflection point (2) between the left horizontal part and the right rising part of the border of light and shadow on the perpendicular drawn through the central mark (3).

The area of most intense illumination should be located to the right of the central vertical line.

• To make it easier to find the inflection point (1), you should alternately close and open the left one several times (in the direction of movement) half of the headlight. After this, check the low beam headlights again.
• The center of the high beam light beam of a headlight with a correctly adjusted low beam must coincide with the center mark (3).

• Adjusting the headlights using a screen with a line inclined at 15° is carried out in the same way as adjusting using a new-style screen.

To avoid adjustment errors, do not use the 15° line as a guide.

Fog lights

When checking, you should make sure that the upper border of light and shadow touches the adjustment line and runs horizontally across the entire width of the screen.

Adjusting headlights with halogen lamps

Left headlight adjustment

The adjustment screws for the right headlight are arranged in a mirror image.

• Vertical adjustment screw (1).
• Screw (2) for vertical and horizontal adjustment.
• Vertical adjustment is achieved by simultaneously rotating screws (1) and (2) by the same number of turns.
• Horizontal adjustment is made by turning the screw (2) only.

Adjusting fog lights installed in headlight assemblies

Correct adjustment of the fog lights installed in the headlight unit is achieved automatically together with the adjustment of the main headlights.

Fog light in the bumper, right

The left fog light adjustment screw is located in a mirror image.

Nominal value of fog lamp inclination: 20 cm.

Release the tabs (arrows) from the clips and remove the trim at the bottom of the bumper.



To adjust the lighting range, rotate the adjusting screw (arrow).

Horizontal adjustment is not provided.
