116Lightingto recognise objects and markings on
the right 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 43 mph.
Curve light
Particular LEDs, based on steering
angle and speed, are additionally
triggered to improve lighting in
curves. This function is activated at
speeds from 25 mph to 43 mph.
High beam assistThis feature activates the high beam
at night when the vehicle speed is
faster than 15 mph.
The camera in the windscreen
detects the lights of oncoming or
preceding vehicles. Each LED on
right or left side can be triggered or
faded out particularly according to the traffic situation. This gives the best
light distribution without dazzling
other road users. Once activated,
high beam assist remains active and
switches high beam on and off
depending on surrounding
conditions. The latest setting of the
high beam assist will remain after the
ignition is switched on again.
High beam assist includes a special
motorway mode. When driving faster
than 71 mph on motorways, the light
beam becomes smaller to avoid
dazzling of oncoming traffic. When
following vehicles ahead or passing,
dazzling for these vehicles is
reduced.
Activation

pressing f. The LED of the button
illuminates if the high beam assist is
activated. High beam is switched on automatically at a speed above
15 mph . High beam is switched off at
