Headlight beam regulator
The height of the headlight beams can be re-
gulated to the laden condition of the vehicle
with the knob (B). This enables maximum
road illumination without dazzling other road
users.
The normal headlight beam setting is obtain-
ed by turning the rotary knob as far as the
noticeable stop, i. e. the white dot must be
in line with "0" (see also "Headlight adjust-
ment").

The beam setting must be corrected as
shown in the table when the vehicle load is
increased. Turning the knob clockwise rai-
ses the beams and vice versa. The correc-
tion should be checked by observing the
dipped beam cut-off (e. g. on the back of the
vehicle driving ahead of you).
Loudspeaker balance control
The volume of the loudspeakers in the door
and in the rear of the vehicle can be balanc-
ed by turning the loudspeaker balance con-
trol knob (A).
