Setting the headlamps correctly is extremely
important. Setting the high-beam headlamps
also sets the low-beam headlamps. (The term
headlamps covers both high and low beam.)
To check and adapt the headlamp setting,

normal range.XSwitch on the low-beam headlamps L.
If the light of the headlamps is not distributed
as shown in the illustration above, follow the
instructions below:
XOpen the hood ( Y page 300).
The adjustment screws are located under the
cover.
XInsert a suitable tool into the openings in
the cover. The directions of arrow =
and ? indicate the angle at which the tool
needs to be inserted in order to reach the
adjustment screws.XTurn both screws uniformly until the
vertical setting of the headlamp
corresponds to :. Turn the screws
clockwise to adjust the headlamp upwards
and counter-clockwise to adjust it
downwards.
Gradation:
R Screw at arrow =: 0.67˚ angle of
inclination
R Screw at arrow ?: 0.50˚ angle of
inclination
The left and right headlamps need to be
adjusted individually.
i If it is not possible to adjust the
