Danger ! | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |

| General information on checking/correcting headlamp adjustment | ||
Preparatory tasks | |||
1 | Determine degree of inclination for main headlamps | ||
| Notes on determining headlamp aiming values | ||
The degree of inclination for the main headlamps is specified on the model plate on the B-pillar on the passenger side. | |||
2 | Park the vehicle on a horizontal, level surface | Maximum permissible height difference of surface for: | |
3 | Align headlamp aimer (01) | | |
Align the headlamp aimer (01) at a distance (A) of approx. 30 cm (11.81 inch) in front of the left or right front lamp unit (E1) based on the reference line (arrows) parallel to the front of the vehicle, level with the left or right low beam headlamp (E1e2). | |||
4 | Prepare vehicle for checking/correcting headlamp adjustment | ||
5 | Set specified degree of inclination for main headlamps at headlamp aimer (01) | ||
6 | Switch on low beam | ||
Check and, if necessary, adjust (checking and adjustment of the low beams is described at the left low beam headlamp (E1e2); the same procedure is used for the right side.) | |||
7 | Check height adjustment of left low beam headlamp (E1e2); adjust if necessary | If, for a low beam light gradient, the height adjustment is correct, the light-dark boundary (1) of the light gradient for the left low beam headlamp (E1e2) to the left of the center mark (3) must be congruent with the reference line for the height adjustment (2) in the headlamp aimer (01), as shown in the color image. The colored area of the light-dark boundary (1) of the left low beam headlamp (E1e2) must be above the reference line for the height adjustment (2), as shown in the color image. | |
If the height adjustment of the left low beam headlamp (E1e2) is not correct: | |||
| |||
Turn the adjustment screw for the height adjustment (H) to correct the height adjustment of the left low beam headlamp (E1e2). | |||
8 | Check lateral adjustment of left low beam headlamp (E1e2); adjust if necessary | If, for a low beam light gradient, the lateral adjustment is correct, the light-dark boundary (1) of the light gradient for the left low beam headlamp (E1e2) starting from the center mark (3) on the right must be congruent with the reference line for the lateral adjustment (4) in the headlamp aimer (01), as shown in the color image. The colored area of the light-dark boundary (1) of the left low beam headlamp (E1e2) must be above the reference line for the lateral adjustment (4), as shown in the color image. | |
If the lateral adjustment of the left low beam headlamp (E1e2) is not correct: | |||
| |||
Turn the adjustment screw for the lateral adjustment (S) to correct the lateral adjustment of the left low beam headlamp (E1e2). | |||
Concluding tasks | |||
9 | Reset switch positions to input condition | Only if the high beam setting is not to be checked afterwards. |
