WARNING Risk of accident despi te
Ad aptive Highbeam Assist
Ad aptive Highbeam Assist does not recog‐
nize thefo llowing road users:
R Road users without lights, e.g. pedes‐
trians
R Road users with poor lighting, e.g.
cyclists
R Road users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist may failto recognize other road users
with their own lighting, or may recognize
th em too late. In
these or similar situations, the automatic
high beam is not deactivated or is activated
despite the presence of other road users. #
Alw ays obser vethe tra ffic carefully and
switch off the high beam in good time. Ad
aptive Highbeam Assist cannot take into
account road, weather or traf fic conditions.
De tection may be restricted in thefo llowing
cases:
R in poor visibilit y,e.g. fog, heavy rain or snow
R ifth ere is dirt on the sensors or the sensors
are obscured
Ad aptive Highbeam Assist is on lyan aid. You are

tive Dis tance Assi stDISTRONIC maintains the
set speed on free-flowing roads. If vehicles in
front are de tected, the set dis tance is main‐
ta ined, if necessar y,until theve hicle comes to a
halt. The vehicle accelerates or brakes depend‐
ing on the dis tance totheve hicle in front and
th e set speed. The speed (in thera nge between
15 mp h (2 0 km/h) and 130mp h (2 10km/h))
and the dis tance totheve hicle in front are set
and sa ved on thesteering wheel. Other

R Reacts tostationary vehicles de tected in
urban speed ranges (e xcept bicycles and
mo torcyc les)
R Initiates acceleration tothestored speed if

Also,
the speed is reduced if the turn signal to
ch ange lanes is swit ched on and one of thefo l‐
lowing situations is de tected:
R Turning off at intersections
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tointersections, traf fic cir‐
cles and traf fic lights, as route-based speed
adap tation does not brake theve hicle toast and‐
st ill.
When route guidance is active, thefirs t speed

Ifth e driver depresses the accelerator or
brake pedal during the process.
Sy stem limitations
Ro ute-based speed adap tation does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
re gulations and driving at a suitable speed.
In dif ficult conditions (e.g. unclear roads, nar row
lanes, wetro ad sur faces, snow or ice) or when

% The availability of thefo llowing function is
countr y-dependent.
Ac tive Lane Change Assi stsupports the driver
when changing lanes byapplying steering torque
if th e driver operates a turn signal.
Assis tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
R You are driving on a free way or road with
multiple lanes in the direction of tr avel.
R The neighboring lane is separated bya bro‐
ke n lane ma rking.
R Novehicle is de tected in the adjacent lane.
R The driven speed is between 50 mph
(80 km/h) and 110mp h (1 80 km/h).
R Active Lane Change Assi stis switched on in
th e multimedia sy stem.
R Active Steering Assist is switched on and
active. If no
vehicle is de tected in the adjacent lane and
a lane change is permit ted, thesteering wheel

suppo rtstarts, the turn signal indicator is auto‐
matically activated.
If a lane change is not possible, the ar row fa des
out af ter a few seconds and a new lane change
must be initiated. An immediate lane change is on
ly possible on free way sections without speed
limits.
If th e sy stem is impaired, Active Lane Change
Assi stmay be canceled. If it is canceled, the
Lane Change Canceled message appears inthe
multifunction display and a warning tone sounds. &
