Speed control cruise control
Function of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Cruise contro l is operated using the cor respond‐
ing steering wheel buttons. You can store any
ro ad speed abo ve15 mp h (20 km/h) up tothe
maximum speed.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
ing in lane. Displa

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) (

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

Active Steering Assist
Function of Active Steering Assist
Active Steering Assist assists the driver at
speeds up to130mp h (2 10km/h) and helps the
driver tostay inthe center of the lane bymeans
of moderate steering inter ventions. The sy stem
orients itself using de tected lane markings.
Depending on the speed driven, Active Steering
Assist uses theve hicles ahead as a refere nce. If
th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem does not
pr ov ide support in thefo rm ofsteering inter ven‐
tions.
RThe driver is requ ired tokeep their hands on
th esteering wheel at all times and be able to
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
RThe status of Active Steering Assist is dis‐
pla yed in thest atus bar of the multifunction
displa y.
Ste ering and contact de tection
The driver is requ ired tokeep their hands on the
st eering wheel at all times and tobe able to
inter vene at any time. The driver must expect a
ch ange from active topassive mode or vice
ve rsa at any time.
If th e sy stem reaches a sy stem limitation or the
driver has not steered theve hicle for a consider‐
able period of time or has remo vedth eir hands
from thesteering wheel, the sy stem will,
depending on the situation, firs t alert the driver
with a visual warning. Display 1appears in the
multifunction displa y.Ifth e driver still does not
st eer theve hicle, or still has not take n hold of
th esteering wheel, a repeated warning tone
sounds in addition tothe visual warning mes‐
sage toremind the driver totake control of the
ve hicle.
The warning message does not appear or disap‐
pears if one of thefo llowing conditions are me t:
RThe driversteers theve hicle.
RThe driver presses a steering wheel button or
operates Touch Control.
Ac tive Steering Assist is only an aid. The driver is
re sponsible forth e dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane. Before changing lanes,
th e driver must make sure that the neighboring
lane is free (glance over the shoulder).

System limitations
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not suff icienttokeep the
ve hicle in the lane or todrive past exits. Active
St eering Assist cann otprov ide the driver with
st eering assis tance at traf fic circles, T-intersec‐
tions, intersections, tollst ations or turns, for
ex ample.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
RIn sno w,rain, fog, heavy spr ay, if there is
gl are, direct sunlight, greatly varying light
conditions, reflections or strong shado wson
th e car riag ewa y.
RInsuf ficient road illumination.
RThe windshield in the area of the camera is
dirty, fogged up, damaged or co vered.
RAbsence of lane markings, or se veral unclear
lane markings, or if the markings change rap‐
idl y.
RThe dis tance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
RThe car riag ewa yis nar rowand winding.
RObstacles on the lane or projecting out into
th e lane.
The sy stem does not pr ovide assis tance in the
fo llowing conditions:
ROn tight bends, traf fic circles and when turn‐
ing.
RIf yo u act ively change lane without switch ing
on the turn signal indicator.

RYou are driving on a highwa yor road with
multiple lanes in the direction of tr avel.
RThe neighboring lane is separated bya bro‐

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
