Halogen Headlamp, Adjusting,
Checking and Adjusting Conditions
• Tire pressure OK
• The headlamp lens must be clean and dry.
• The headlamp lens may not be damaged.
• Headlamp reflectors and bulbs OK.
• Vehicle load must be created.
Vehicle load on driver's seat in otherwise unloaded vehicle (curb weight).
• One person or 75 kg (165 lbs.).
The curb weight is the weight of the operational vehicle with completely full fuel tank, including the weight of all equipment carried in operation.
• Fuel tank: at least 90% full.
• Equipment: for example, spare wheel, tools, vehicle jack, fire extinguisher, etc.
If the fuel tank is not at least 90% full, the load must be created as follows.
- Check fuel tank fill lever in instrument cluster tank gauge and compare with the following table. Place additional weight in the luggage compartment, if necessary.
• Use fuel containers filled with water as additional weight (a 5 liter (1.3 gal.) fuel container filled with water weighs 5 kg (11 lbs.).
• The electromechanical parking brake must not be engaged so vehicle is not under stress.
• Vehicle and headlamp adjusting unit must be on a level surface.
• The headlamp adjusting unit must be aligned to the vehicle. Refer to Headlamp adjusting unit instructions.
• The headlamp adjuster must be distance - a - 30 to 70 cm (11.8 to 27.5 in.) in front of the headlamp and should not deviate more than dimension - b - = 3 cm (1.2 in.) from the headlamp center point.
• The inclination dimension is set on the headlamp adjusting unit. Refer to Headlamp adjusting unit operating instructions.
• The angle dimension - arrow - is stamped on the upper edge of the headlamp - 1 - in "%".
Procedure
- The vehicles must be standing on a flat surface.
- Turn the headlamp switch to "low beam" - not "Auto".
- Set the range position thumbwheel to the "0" position.
Headlamp adjustment
• The horizontal light-dark border must touch the dividing line - 1 - on the adjusting unit test surface.
• The point - 2 - between the left horizontal part and the right vertical part of the light-dark border must run vertically through the central mark - 3 -. The bright core of the light beam must be to the right of the vertical.
• To determine the point - 2 - more easily, cover and uncover the left half of the headlamp several times. Then check low beam again.
• After correct headlamp adjustment, the center of the high beam light beam must be on the central marking - 3 -.
- To adjust the height of the headlamp, set the light-dark border just under the dividing line with the adjustment screw - 2 -.
- Then adjust the light-dark border, starting from the bottom, on the dividing line.
- Turn the adjusting screw - 1 - to adjust laterally.
• The allocation on the right headlamp is reversed.
