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.

high beam assist will remain after the
ignition is switched on again.
High beam assist includes a special
motorway mode. When driving faster

beam becomes smaller to avoid
dazzling of oncoming traffic. When
following vehicles ahead or passing,
dazzling for these vehicles is
reduced.
