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

WARNING
DI ST RONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
The ydon ot relieve you of the responsibility
of payin gattention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in time, cause an accident and injure yourself
and others.
If you change to the overtakin glane, DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintaining the dis-
tance to avehicle in front.
R you switc honthe respective tur nsignals.
R DISTRONIC PLU Sdoes not detec tadanger
of collision.
If these condition sare met, your vehicl eis
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane for left-hand-drive
vehicles and the right lane for right-hand-
drive vehicles.
Vehicles with COMAND Online Example: roundabout

The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
adapt to certain traffic situations. This is the
