HID Headlamp, Adjusting
HID 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.
With Steel Suspension
• Vehicle load must be created.
Vehicle load on driver's seat in otherwise unloaded vehicle (curb weight).
• One person or 75 kg (165 lb.).
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 lb.).
With Air Suspension
• The compressed air reservoir must be filled. Start the engine and let it run at idle for approximately 2 minutes.
All Vehicles
• 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 (12 to 27.5 in.) in front of the headlamp and should not deviate more than dimension - b - = 3 cm 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 "%".
• The headlamp must be adjusted according to the angle dimension stamped on the headlamp.
• The percentage indicator is based on a 10 meter (33 ft.) projection distance. At an angle dimension of 1.0%, for example, converts to 10 cm (4 in.).
Procedure
- The vehicles must be standing on a flat surface.
- Turn the headlamp switch to "low beam" - not "Auto".
- Close all the doors and the rear lid and keep them closed for the duration of the testing/adjusting procedure.
- To prepare for the headlamp adjustment, in "Guided Functions", select "basic setting" on the Vehicle Diagnostic Tester.
• The headlamps move into the basic setting with this program.
• If the vehicle has air suspension, the suspension will move into the air suspension normal level at the same time.
- Select the function or path:
- Follow the instructions on the Vehicle Diagnosis Tester display.
- During the program, you will be asked to perform a headlamp adjustment.
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 the 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 above the dividing line with the adjustment screw - 1 -.
- Then adjust the light-dark border, starting from the top, on the dividing line.
- For side adjustment, turn adjusting screw - 2 -.
• The allocation on the right headlamp is reversed.
- After the headlamp adjustment has been successful, follow the instructions on the Vehicle Diagnosis Tester display in order to leave the air suspension normal level.
• If the program gets interrupted, then the air suspension normal level must be deactivated manually.
- Disconnect the diagnostic connector.
