112LightingMotorway light
Activated automatically at a speed
above 115 km/h. Illumination is
adapted to the higher speed driven on
motorways. If there is no oncoming
traffic, the visibility on the side of the
vehicle is increased. The visibility
range raises from 70 m to 140 m
allowing distant objects to be
recognised across the entire width of
the road.
Town light
Activated automatically at a speed up to approx. 55 km/h and in situations
with exterior ambient light. The light is
wide and symmetrical. If the speed is
below 30 km/h, the headlamps are
slightly swiveled to the outside to
allow an earlier recognition of of
pedestrians and objects on each side
of the road. A special beam pattern is
designed to avoid glare for other road users.
Corner light
Activated at a speed of up to 40 km/h
when turning off. The light consists of particular LEDs which illuminate the
direction of travel. These LEDs are
triggered depending on the steering
angle or the activation of the turn
lights.
Adverse weather light
Controlled by wiper or rain sensor.
The wide light distribution – slightly
swiveled to the outside – enables
improved orientation at the edge of
the road. The intensity of the light in
the far distance is increased in order
to recognise objects and markings on
the front passenger road side and
obstacles on the lane despite the
weather condition. By lowering the
reflection on wet roads the oncoming
traffic is less dazzled. Adverse
weather light is activated up to a
speed to 70 km/h. 

Lighting115is moved in the opposite direction or
indicator lever is manually moved
back to its neutral position.
Activate temporary flashing by
holding the indicator lever just before
the resistance point. Turn lights will
flash until indicator lever is being
released.
To activate three flashes, tap the
indicator lever briefly without passing
the resistance point.
If you forget to cancel the turn lights
for more than 20 seconds, the volume
of the audible signal will increase if
the speed is above 60 km/h.Front fog lights
