118LightingCurve light
Particular LEDs, based on steering
angle and speed, are additionally
triggered to improve lighting in
curves. This function is activated at
speeds from 40 km/h to 70 km/h.
High beam assist This feature allows the high beam to
function as main driving light at night.
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 115 km/h 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
Activate the high beam assist by
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
25 km/h. High beam is switched off at a speed below 15 km/h, but high
beam assist remains active.
The green control indicator f
illuminates continuously when the
high beam assist is activated, the blue
7 illuminates when high beam is on.
Control indicator f 3 99, 7 3 99.

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.

hazard warning flashers are switched
on automatically depending on the
