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 | Check operation of headlamp range adjustment | For vehicle with headlamp range controller (6). | |
2 | 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. | |||
3 | Park the vehicle on a horizontal, level surface | Maximum permissible height difference of surface for: | |
4 | Align headlamp aimer (01) | | |
Align the headlamp aimer (01) at a distance (A) of approx. 30 cm in front of the left or right front lamp unit (E1) level with the left or right low beam headlamp (E1e2) parallel to the front of the vehicle. | |||
5 | Prepare vehicle for checking/correcting headlamp adjustment | ||
6 | Set specified degree of inclination for main headlamps at headlamp aimer (01) | ||
7 | 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.) | |||
8.1 | Check height adjustment of left low beam headlamp (E1e2); adjust if necessary | For vehicle with steel suspension on front and rear axle. | |
If, for a low beam light gradient, the height adjustment is correct, the light-dark boundary (1) of the left low beam headlamp (E1e2) in each case 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. | |||
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). | |||
8.2 | Check height adjustment of left low beam headlamp (E1e2); adjust if necessary | For vehicle with level control on front and rear axle. | |
If, for a low beam light gradient, the height adjustment is correct, the light-dark boundary (1) of the left low beam headlamp (E1e2) in each case 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. | |||
If the height adjustment of the left low beam headlamp (E1e2) is not correct: | |||
| |||
Move to calibrated vehicle level. | |||
Diagnosis Control units view Chassis ADS - Adaptive Damping System Actuations Move to calibrated vehicle level and check headlamp adjustment again. | |||
| |||
| |||
Headlamp adjustment incorrect: | |||
| |||
Calibrate level in chassis control unit. | |||
Diagnosis Control units view Chassis ADS - Adaptive Damping System Adaptations Teach-in processes Check level calibration and headlamp adjustment again. | |||
| |||
If the height adjustment of the left low beam (E1e2) is still incorrect after calibration of the vehicle level and the level calibration: | |||
| |||
Turn the adjustment screw for the height adjustment (H) to correct the height adjustment of the left low beam headlamp (E1e2). | |||
9 | 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. | |
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 | |||
10 | Reset switch positions to input condition | Only if the high beam setting is not to be checked afterwards. |
