The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lightin gisnot clearly visi-
ble, e.g. road users behind acras hb arrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. You can use this function to set the head-
lamps to change between dippe dbeam and
mai nbeam 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 headlam prange depending on the dis- tanc
etot he other vehicle. Onc ethe system
no longer detec tsany other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical senso risl ocated behind
the windscreen near the overhead con trol
panel.

If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in fron thas slowed down, it brakes your vehi-
cle. In this way, the distanc eyou have selec-
ted is maintained.
If DI STRONIC PLUS detects afaster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up
to the spee dyou have stored.

tance to avehicle in front.

if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.

monitors the left lane for left-hand-drive
vehicles and the right lane for right-hand-
drive vehicles.
