♦ Dip setting must be adjusted.
Dip settings (in “%”) are marked on the top of the headlight. The
headlights must be adjusted in accordance with these values. The
percentage value is for a range of 10 m. Example: Converting a
dip setting of 1.0 % = 10 cm.
4.4.2 Checking headlight settings
– Start engine.
– Switch on dipped headlights.
– Set vehicle level to normal.
– To do so, press the function selector button “CAR” on the MMI
operating unit. The main menu “adaptive air suspension” will
appear.

Further information on the vehicle level can be found in the ⇒
MMI Operating Manual
♦ The horizontal light-dark border should coincide with the set‐
ting line -1- of the test surface.
♦ The break-away point -2- between the horizontal section of the
light-dark border on the left and the rising section on the right
should coincide with the vertical line running through the cen‐
tral point -3-. The bright spot in the centre of the beam should
be to the right of the vertical line.
Note
♦ To make it easier to find the break-away point -2-, cover and
uncover the left half of the headlight (as seen in direction of
travel) a few times. Then check the dipped beam again.
♦ If dipped beams have been adjusted correctly the centre point
of the main beam should lie on central point -3-.
♦ If using an old test screen with a 15 ° setting line, the adjust‐
ment procedure is the same as for the new screen. Disregard
the 15° setting line to avoid incorrect settings.
– If headlight setting is not OK, adjust headlights ⇒ page 151 .
