Not active: if, following activation, you are
driving at speeds above 100 km/h or if you
switch off the rear foglamp.
Off-road lights The off-road lights facilitate the early recog-
nition of objects/obstacles when driving off-
road thanks to a symmetrical, wider and
brighter distribution of light from the dipped-
beam headlamps.
Active: when driving at speeds not faster
than 50 km/h and the off-road program is
selected (Y page 205).
Not active: when driving at speeds above
50 km/h. When the off-road lights are switched on, the
active light function is deactivated and the
headlamp range control is set to static mode. Adaptive Highbeam Assist
General notes You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped- beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it
switches on the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. Exterior lighting

WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
recognises road users too late or not at all. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You
are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or if the sensors are
obscured

when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
