Lighting and Horns: Testing and Inspection
Electrics Maintenance: Checking The Function Of The Vehicle's Lights
Adjusting the main headlights
1. Open the luggage compartment lid.
2. Remove the luggage compartment mat on the wheel housing wall.
3. Open the cover for the headlight adjustment screws.
4. Clean the cover lens and switch on the dipped beam headlights.
NOTE:
- The vehicle must be on a horizontal surface.
- Make the adjustment with the regulator switch set to 0 (headlight beam adjustment).
- Use a standard 5 mm ball-head screwdriver to make the headlight adjustment (free blade length 150 mm).
- Only the lower screw may be turned for height adjustment; for lateral adjustment the upper and lower screws must be turned in the same direction and for the same number of rotations.
5. Make the adjustment with the vehicle ready for driving (fuel tank full, driver's seat occupied by a person or 75 kg, the tyre pressure must correspond to the stipulated values) using a headlight adjustment unit.
Setting
NOTE:
- Set the headlight adjustment unit to 10 cm/10 m (1%).
- With this alignment, preference must be given to the central zone around the salient point of the light/dark limit.
First, make the vertical adjustment of the dipped beam headlights.
1. To do this, line up the light/dark borderline running upwards at an angle on the right-hand side with the dotted 15 degree line of the adjustment unit.
Next, perform the horizontal adjustment of the dipped beam headlight
2. To do this, line up the left, horizontal part of the light/dark limit (in the case of driving on the right) with the dotted horizontal line of the adjustment unit.
NOTE:
- The distance between the headlights and the adjustment unit should be as small as possible.
- It should not exceed 30 cm, because if the distance is greater, it is no longer possible to define the formation of the light/dark limit in the adjustment unit clearly.
3. Secure the plugs after making the adjustment.
4. For Xenon headlights the ignition must be switched off and on after adjustment with the lights switched on.
5. After this, the adjustment must be checked again.
Adjusting the main headlights, USA version
NOTE: A new adjustment may only be made in the case of accident repairs or replacement of the main headlights.
- Vertical and horizontal adjustment must be carried out with a headlight adjustment unit.
Fog light adjustment
NOTE: The vehicle must be on a horizontal surface.
- Make the adjustment with the vehicle ready for driving (fuel tank full, driver's seat occupied by a person or 75 kg, the tyre pressure must correspond to the stipulated values) using a headlight adjustment unit.
NOTE: Switched-on headlights must not be covered by a front apron or film.
Removing main headlight
NOTE:
- Risk of damage to headlights due to chafing and excessive temperatures.
- Headlights must not be covered when they are switched on, e.g. wing protection or film.
1. Release the side carpet by unscrewing plastic nut -A- -arrow-.
2. Pull rubber stopper -B- off the release opening.
3. Place the socket wrench from the tool kit on the release axle.
4. The toggle of the socket wrench should point horizontally to the rear.
5. Turn the socket wrench through approx. 180� -arrow A- and leave it in position.
6. The headlight is now unlocked and can be pulled forwards out of the wing.
7. Turn the socket wrench back until it points vertically -arrow B- downwards.
Installing main headlight
NOTE: Do not attach any covers (e.g. stone shields or films) in the area of the headlights.
1. Insert the headlight into the guide rails and push it fully into the wing -arrow-.
2. Press the headlight to the rear, turning the socket wrench at the same time until the wrench points horizontally to the rear -arrow C-. In the process, the headlight lock must engage with an audible and perceptible click.
3. Check the correct seating of the headlight, e.g. by pulling gently in the area of the fog light.
4. Insert rubber stopper in the release opening.
5. Screw the side carpet tight with the plastic screw -A-.
