  General information on checking/correcting headlamp adjustment   AH82.10-P-1000-01A
  Preparatory activity     
1 Prepare vehicle for checking/correcting headlamp adjustment   AP82.10-P-8260-10H 
2 Determine degree of inclination for main headlamps
Notes on determining headlamp aiming values
IMPORTANT The degree of inclination for the main headlamps is specified on the model plate on the B-pillar on the passenger side. AH82.10-P-1005-01A
3 Set specified degree of inclination for main headlamps on headlamp aimer (01)    
REFER TO SPECIAL TOOLS 000 588 11 21 00 Adjustment device   WS82.00-P-0151B
4 Switch on low beam IMPORTANT When testing and adjusting the low beams, make sure that the extended fog light function is not active.  
  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.)     
5 Check height adjustment of left low beam headlamp (E1e2); adjust if necessary    
REFER TO SPECIAL TOOLS 000 588 11 21 00 Adjustment device IMPORTANT When the diagnostic light pattern is switched on and the height adjustment is correct, the horizontal light-dark boundary (1) of 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).
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).
If the height adjustment of the left low beam headlamp (E1e2) is correct with the diagnostic light pattern switched on.
↓
No further check necessary, continue with operation step 6.
If the height adjustment of the left low beam headlamp (E1e2) is not correct with the diagnostic light pattern switched on.
↓
Turn the adjustment screw for the height adjustment (H) to correct the height adjustment of the left low beam headlamp (E1e2).
WS82.00-P-0151B
6 Check lateral adjustment of left low beam headlamp (E1e2); adjust if necessary    
REFER TO SPECIAL TOOLS 000 588 11 21 00 Adjustment device WS82.00-P-0151B
    IMPORTANT When the diagnostic light pattern is switched on and the lateral adjustment is correct, the vertical light-dark boundary (1) of the left low beam headlamp (E1e2) each starting at the center mark (3) must run upward at 900 to the reference line for the height adjustment (2) in the headlamp aimer (01).
The colored area of the vertical light-dark boundary (1) of the left low beam headlamp (E1e2) must be to the left of the center mark (3).
If lateral adjustment of left low-beam headlamp (E1e2) is correct.
↓
No further check necessary, continue with operation step 7.
If 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).
 
  Finishing activity     
7 Reset switch positions to input condition Only if the high beam setting is not to be checked afterwards.
