	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 activity
1	Check operation of headlamp range adjustment	On vehicle with headlamp range adjuster (6).	AP82.10-P-8250EW
2	Prepare vehicle for checking/correcting headlamp adjustment		AP82.10-P-8260-10I
3	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
4	Set specified degree of inclination for main headlamps on 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, 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 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 height adjustment of left low-beam headlamp (E1e2) is correct. ↓ No further check necessary, continue with operation step 7. If height adjustment of left low beam (E1e2) is not correct. ↓ Correct height adjustment of left low-beam headlamp (E1e2) by turning adjustment screw for height adjustment (H).
7	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 lateral adjustment of left low-beam headlamp (E1e2) is correct. ↓ No further check necessary, continue with operation step 8. If lateral adjustment of the left low beam headlamp (E1e2) is not correct. ↓ Turn adjustment screw for lateral adjustment(S) to correct lateral adjustment of left low-beam headlamp (E1e2).
	Finishing activity
8	Reset switch positions to input condition	Only if the high beam setting is not to be checked afterwards.
