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
left hand drive traffic and it is
driven in a country with right hand
drive traffic.
Switch off glare-free high beam
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.
Glare-free high beam is switched on
automatically at a speed above
31 mph. It is switched off at a speed
below 22 mph, but the system
remains active.
Motorway mode
Activated automatically at a speed
above 65 mph. 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. When following
vehicles ahead or passing, dazzling
for these vehicles is reduced.
Fault in LED headlight system
When the system detects a failure in
the LED headlight system, it selects a preset position to avoid dazzling of
oncoming traffic. A warning is
displayed in the Driver Information
Centre.

deactivated when the steering wheel
is 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 50 mph.
