Extended range foglamps
The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
Active: if you are driving at speeds below
70 km/h and you switch on the rear foglamp
Not active: if, following activation, you are
driving at speeds above 100 km/h or if you
switch off the rear foglamp
Adaptive Highbeam Assist Plus
General notes
With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam head-
lamps.
Partial main-beam illumination is a form of
illumination whereby the main beam is direc-
ted past other road users. Other road users
are kept out of the main-beam. This prevents
glare. If there is a vehicle in front, for example,
the main-beam headlamps illuminate the
areas to its right and left, and the vehicle in
front is illuminated by the dipped-beam head-
lamps.
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.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from
traffic signs, the lights are automatically dim-
med and glare for the driver caused by the
reflections is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes
G WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise road users:
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
R
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the main-beam headlamps in
good time.
