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.
•
•
Refer to the ⇒ operating instructions for headlight adjust‐
ment units.
The current software for the headlight adjustment unit -VAS
621 001- is available on the equipment manufacturer’s
homepage.
1)
During the initialisation, the step motors for the headlight
range control are reset to dipped beam position. The initialisa‐
tion of the headlight range control is performed during vehicle
start or after an "on" signal is applied to terminal 15.

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
checked as an alternative. ⇒ page 143
♦ 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.

Note
♦ The VOL/VOR marking is visible on the outside the head‐
light.
♦ The lateral adjustment mechanism is sealed on SAE-compli‐
ant headlights.

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‐

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.

– Turn height adjustment screw -1- until setting is correct.
– Turn lateral adjustment screw -2- until setting is correct. The
lateral adjustment mechanism is sealed on SAE-compliant
headlights.
Subsequent check of left headlight
Note
♦ The subsequent check of the headlight is performed using
the test pattern for the dipped beam headlight.
♦ It is not permitted to change the lateral setting of the head‐
light any more during the check. Readjusting the vertical
setting is permissible.
– Check headlight setting.
– Adjust height setting of headlight, if necessary.
Note
♦ Adjustment of the right headlight is carried out in the same
sequence.
♦ The adjustment screws for the right headlight are a mirror
