 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.

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 headlamp check/headlamp adjustment

AP82.10-P-8260-10SR


Before the low beams are checked and set, all operation steps listed in the linked description must be performed carefully.
Otherwise it cannot be guaranteed that the headlamps concerned are correctly set, which can then jeopardize the road safety of the vehicle!

4

Align headlamp aimer (01)



000 588 11 21 00 Adjustment device

WS82.00-P-0151B


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) based on the reference line (arrows) parallel to the front of the vehicle, level with the left or right low beam (E1e2).
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 at exterior lights switch_(5)

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.)

7

Check operation of headlamp range adjustment

Only vehicles with headlamp range controller (6).

AP82.10-P-8250EW


Move headlamp range controller (6) to position "0" at end of test.
The headlamp adjustment will otherwise be incorrect, which can then jeopardize the road safety of the vehicle!

8

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), corresponding to the colored representation.

If the height adjustment of the left low beam headlamp (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).

9

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), corresponding to the colored representation.

If the lateral adjustment of the left low beam headlamp (E1e2) is not correct:



Subject to a separate repair order, check and correct the installation position of the headlamp concerned.

Then work through operation steps 2 to 9 again.

Concluding tasks

10

Reset switch positions and, if necessary, load condition of vehicle to initial condition

Only if the high beam or fog lamp setting is not to be checked afterwards.
