Glare-free high beam
9 Warning
The glare-free high beam function
may dazzle other road users when the vehicle is driven in countrieswhere traffic moves on the
opposite side of the road. E.g.
when the vehicle was designed for

function whenever you are driving in countries mentioned above!
The system enables a glare-free high beam when driving in dark
surroundings.
Each LED on right or left side is
triggered or faded out particularly according to the traffic situation. This
gives the best light distribution
without dazzling other road users.

automatically at a speed above
31 mph. It is switched off at a speed
below 22 mph, but the system
remains active.
Motorway mode
