	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.	AS00.00-Z-0005-01A
	General information on checking/correcting headlamp adjustment		AH82.10-P-1000-01A
	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.	AH82.10-P-1005-01A
2	Park the vehicle on a horizontal, level surface	Maximum permissible height difference of surface for: Vehicle: ± 1 mm/m Headlamp aimer (01): ± 0.5 mm/m
3	Align headlamp aimer (01) 000 588 11 21 00 Adjustment device	It is essential to align the headlamp aimer (01) parallel to the front of the vehicle. The headlamp adjustment will otherwise be incorrect, which then may jeopardize the road safety of the vehicle! 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. Other country-specific regulations or specifications in the operating instructions from the headlamp aiming device manufacturer must be observed accordingly.	WS82.00-P-0151B
4	Set specified degree of inclination for main headlamps at headlamp aimer (01)
5	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.)
6	Check height adjustment of left low beam headlamp (E1e2); adjust if necessary	If 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), corresponding to the colored representation. 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: ↓ Conduct zero position adjustment using diagnostic system in the chassis control unit and run through operation steps 2 to 6 again.
		If the height adjustment for the left low beam (E1e2) is still not correct after the zero position adjustment and processing operation steps 2 to 6: ↓ Turn the adjustment screw for the height adjustment (H) to correct the height adjustment of the left low beam headlamp (E1e2).	AD00.00-P-2000-04B
7	Check lateral adjustment of left low beam headlamp (E1e2); adjust if necessary	If 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), corresponding to the colored representation. 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
8	Reset switch positions to input condition	Only if the high beam setting is not to be checked afterwards.
