 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.	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		AH82.10-P-1005-01A
		 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: Vehicle: 1 mm/m, Headlamp aimer (01): 0.5 mm/m.
3	Prepare vehicle for checking/correcting headlamp adjustment		AP82.10-P-8260-10C
4	Align headlamp aimer (01)	 It is essential to align the headlamp aimer (01) parallel to the front of the vehicle. The headlamp adjustment will otherwise be incorrect, which can then 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 (long range) (E1e16) 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.
5	Set specified degree of inclination for main headlamps at headlamp aimer (01)
6	Switch on low beam	 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 (long range) (E1e16); the same procedure is used for the right side.)
7.1	Check height adjustment of left low beam headlamp (long range) (E1e16); 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 light gradient for the left low beam headlamp (long range) (E1e16) 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 colored image. The colored area of the light-dark boundary (1) of the left low beam headlamp (long range) (E1e16) must be above the reference line for the height adjustment (2), as shown in the color image.

		
		Turn the adjustment screw for the height adjustment (H) to correct the height adjustment of the left low beam headlamp (long range) (E1e16).
7.2	Check height adjustment of left low beam headlamp (long range) (E1e16); 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 light gradient for the left low beam headlamp (long range) (E1e16) 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 colored image.

The colored area of the light-dark boundary (1) of the left low beam headlamp (long range) (E1e16) must be above the reference line for the lateral adjustment (4), as shown in the color image. 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 (long range) (E1e16) 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 (long range) (E1e16) must be to the left of the center mark (3).
