WARNING Risk of accident despite
Ad aptive Highbeam Assist
Ad aptive Highbeam Assist does not recog‐
nize thefo llowing road users:
RRo ad users without lights, e.g. pedes‐
trians
RRo ad users with poor lighting, e.g.
cyclists
RRo ad 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.
Sy stem limitations
Ad aptive Highbeam Assist cannot take into
account road, weather or traf fic conditions.
De tection may be restricted if:
RVi sibility is impaired, forex ample in fog,
heavy rain or sno w.
RThere is dirt on the sensors or the sensors
are obscured.
Ad aptive Highbeam Assist is only an aid.You are

Ac tive Di stance Assist DI STRONIC
Function of Active Di stance Assist
DI STRO NIC
Active Dis tance Assist DISTRONIC maintains the
set speed on free-flowing roads. If vehicles
ahead are de tected, the set dis tance is main‐
ta ined, if necessar y,until theve hicle comes toa
halt. The vehicle accelerates or brakes depend‐
ing on the dis tance totheve hicle in front and
th e set speed. Speed (in thera nge between
15 mp h(2 0 km/h) and 130mp h(210 km/h))
and the dis tance totheve hicle ahead are set
and sa ved on thesteering wheel. Other
features of Active Dis tance Assist
DISTRONIC:
RAd justs the driving style depending on the
selected drive program (fuel-saving, comfort‐
able or dynamic) (
→page 136)
RRe acts tostationary vehicles in urban speed
ra nges (e xcept bicycles and mo torcyc les) if
conditions are suf ficient toenable de tection.
It also does not de tect pedestrians.
RInitiates rapid acceleration tothestored
speed, if the turn signal indicator is switched
on tochange totheove rtaking lane.
RTa ke s one-sided overtaking restrictions into
account on highw ays or on multi-lane roads
with separate roadw ays.
Ve hicles with Active Parking Assis t:ifth eve hicle
has been braked toast andstill on a multi-lane,
separate roadw ay by Active Dis tance Assist
DISTRONIC, it can au tomatical lyfollow th
eve hi‐
cle in front driving off again within 30 seconds. If
a crit

ical situation is de tected when driving off, a
visual and acoustic warning is given indicating
th at the driver must now take control of theve hi‐
cle. The vehicle is not accelerated any fur ther.

Driving and pa rking

Also,the speed is reduced if the turn signal to
ch ange lanes is switch ed on and one ofthefo l‐
lowing situations is de tected:
RTu rning off at intersections
ROn slowing-down lanes
ROn 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 sets of traf fic lights, as route-based
speed adap tation does not brake theve hicle toa
st andstill.
When route guidance isact ive, thefirs t speed
adjustment is car ried out automaticall y.Ifth e
turn signal indica tor is switched on, the selected
ro ute isconf irmed and fur ther speed adjustment
is activated.
Speed adjustment is canceled in thefo llowing
cases:
RIf th e turn signal indicator is switched off
before thero ute event.
RIfth e driver depresses the accelera tor or
brake pedal during the process. Sy
stem limitations
Ro ute-based speed adaptation 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
driving wi tha trailer, the speed adjustment made
by the sy stem may not alw
ays be suitable. In
th ese sit

uations the driver must inter vene
acco rdingly.

tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
RYou are driving on a highwa yor road with
multiple lanes in the direction of tr avel.
RThe neighboring lane is separated bya bro‐

RNovehicle is de tected in the adjacent lane.
RThe driven speed is between 50 mph
(80 km/h) and 110mp h(1 80 km/h).
RAc tive Lane Change Assi stis activated bythe
driver with the turn signal indicator.
RAc tive Lane Change Assi stis switched on in

been activated with the turn signal indicator but
a lane change is not immediately possible, the
st eering wheel symbol remains green and the
ar row appears gray 1. When the lane change
support starts, the turn signal indicator is auto‐
matically activated. If a lane change is not possi‐
ble, the ar row fa des out af ter a short period and
a new lane change must be initiated. An immedi‐
ate lane change is only possible on highw aysec‐
