Headlight adjustment: checking LED
headlights with cornering light
Note
♦ Additional weights are no longer used.
♦ Instead, a different inclination setting on the headlight adjust‐
ment unit is used.
♦ If the maintenance tables are used, the settings are dis‐
played in the vehicle-specific maintenance list.
♦ In the US, Canadian and Mexican markets SAE-compliant
headlights are used.
♦ The headlight adjustment is subject to a separate charge.

Test and adjustment conditions
•
•
•
•
Tyre pressure OK
Headlight lenses must not be damaged or dirty.
Reflectors and lights OK
The initialisation of the headlight range control must have
1)
been completed.
•
The vehicle must be rolled forward and backward several
metres or front and rear springs must be bounced fully sev‐
eral times so that springs settle.
•
•
•
•
•
Vehicle and headlight adjuster must be on a level surface.
Vehicle and headlight adjustment unit must be aligned.
Inclination must be set.
Event memory must be cleared.
If the headlight adjustment unit has an adjustment mode,
select it.
•
•
Dynamic cornering light must be deactivated ⇒ page 166 .
Refer to the ⇒ operating instructions for headlight adjust‐
ment units.
•

Deactivate dynamic cornering light in Infotainment system
Note
♦ Deactivation is not necessary if the “city light” mode was de‐
activated by switching the ignition off and on and actuating
the headlight flasher.
♦ Both headlights must have a symmetrical and an asymmetri‐
cal light section.
The cornering light is deactivated as this ensures that no head‐
light is in “city light” mode.
In “city light” mode, the headlight setting cannot be checked.
– Switch on ignition.
– Switch on Infotainment system.
– Press Infotainment CAR button.
– Press Setup function button.
– Press Light function button.
– Press Dynamic cornering light function button and re‐
move tick.
Dynamic cornering light is now deactivated.
Note
After adjusting the headlights, the dynamic cornering light must
be reactivated.

Special tools and workshop equipment required
♦ Headlight adjustment unit -VAS 5046 A-
♦ Headlight adjustment unit -VAS 5047 A-
♦ Headlight adjustment unit -VAS 621 001-
♦ Vehicle diagnostic tester

Test pattern with dynamic main beam
Note
♦ For dynamic main beam test pattern, headlights need to be
reset to basic settings using vehicle diagnostic tester.
♦ The basic settings can only be reset using vehicle diagnostic
tester. After resetting, DLA main beam distribution is actu‐
ated automatically.
♦ Pay special attention to correct alignment of the adjustment
sighting device on the headlight adjuster. Only when this has
been done can you adjust the headlights to ensure that they
do not dazzle other road users.
♦ In vehicles with DLA the dipped headlight setting can be
♦ DLA: “Dynamic Light Assist”, dynamic high beam regulation.
Check the following:
– Whether the horizontal light-dark border touches the sepa‐
rating line -1- in the test area when the main beam is on.
– Whether the breaking point -2- between horizontal part of
the light-dark border on the right and the rising part on the
left lies on the vertical line of the central point -3-. The bright
core of the light beam must be to the left of the vertical line.
Note
The setup pattern applies only to the left headlight. The setup
pattern for the right headlight is a mirror image.
Test pattern with dipped headlights
Testing may also be carried out with dipped headlights switched
on. Nevertheless, said dynamic main beam test pattern is pre‐
ferred.
For checking dipped headlight it is not necessary to use the
vehicle diagnostic tester.
The headlight setting can also be carried out using the dipped
headlight test pattern.
– With the dipped beam switched on, the lowest part of the
horizontal light-dark border must touch the dividing line -1- of
the test area

– The breaking point -2- between the horizontal part of the
light-dark border on the left and the slope on the right should
be on the vertical line passing through the centre mark.
If no light-dark border with rising asymmetric portion can be
seen in the left headlight (right-hand drive) or in the right head‐
light (left-hand drive), the “city light” function must be deactiva‐
ted.
The city light feature is used to ensure that oncoming traffic is
not dazzled up to a speed of 30 km/h in city traffic.

♦ Vehicle diagnostic tester
Note
♦ The VOL/VOR marking is visible on the outside the head‐

♦ The lateral adjustment mechanism is sealed on SAE-compli‐
ant headlights.
