2	Prepare vehicle for checking/correcting headlamp adjustment.		AP82.10-P-8260-10J
3	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.
4	Adjust specified degree of inclination for main headlamps at headlamp adjuster (01).

5	Switch on low beams.
6	Open hood.
	Check and, if necessary, adjust (checking and adjusting the low beams is described at the left low beam (E1e2) in the left front lamp unit (E1), use procedure for left side for right side too.)
7	Check height adjustment of left low beam (E1e2), adjust if necessary.
	000 588 11 21 00 Adjustment device		WS82.00-P-0151B
		 For a low beam light gradient with the correct height adjustment, the light/dark boundary (1) of the left low beam (E1e2) must be congruent with the datum line for height adjustment (2) in the headlamp adjuster (01) respectively to the left of the center mark (3), 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 the height adjustment for the left low beam (E1e2) is correct,
		
		No further check necessary, continue with operation step 8.
		If the height adjustment for the left low beam (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	Check lateral adjustment of left low beam (E1e2).	Model 177 with code 460 (Canada version) with code 632 (Headlamps, LED, static, right-side traffic) Model 177 with code 494 (US version) with code 632 (Headlamps, LED, static, right-side traffic)
	000 588 11 21 00 Adjustment device		WS82.00-P-0151B
		 For a low beam light gradient with the correct lateral adjustment, the light/dark boundary (1) of the left low beam (E1e2) must be congruent with the datum line for lateral adjustment (4) in the headlamp adjuster (01) starting from the center mark (3) on the right, 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 the lateral adjustment of the left low beam (E1e2) is correct.
		
		No further check is necessary; continue with operation step 9.
		If the lateral adjustment of the left low beam (E1e2) is not correct.
		
		Check installation position of corresponding headlamp and correct; then proceed with operation steps 2 to 8 again.
		 After obtaining special order.
