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 and dis tance tothe
ve hicle in front are set and sa ved on thesteering
wheel on vehicles without the Driving Assis tance
Pa ckage, in thera nge between 20 km/h and
200 km/h and, on vehicles with the Driving Assis
tance Package, in thera nge between
20 km/h and 210 km/h.
The adju stable set speed can vary due tothefo l‐
lowing factors:
R Plug-in hybrid: drive prog ram selected,
obser vethere leva nt no tes in the Supple‐
ment.
R Maximum speed, e.g. winter tyre limit
(/ page 226)
Other features of Active Dis tance Assi st
DISTRONIC:
R Adjusts the driving style depending on the
selected drive program (fuel ef ficient, com‐
fo rtable or dynamic) (/ page186)
R Vehicles with Driving Assistance Pack‐
age: reacts tostationary vehicles de tected in
urban speed ranges (e xcept bicycles and

% The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package.
Ac tive Steering Assist is only available up to a
speed of 210 km/h. The sy stem helps youto
st ay inthe cent reofthe lane bymeans of mod‐
erate steering inter ventions. Depending on the
speed driven, Active Steering Assist uses the
ve hicles ahead and lane markings as a refer‐
ence. %
Depending on the count ry, in the lo wer
speed range Active Steering Assist can use
th e sur rounding traf fic as a refere nce. If nec‐
essar y,Ac tive Steering Assist can then also

When the sy stem is actively steering, theà
symbol is shown in green in the multifunction
displa y.
If th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem pr ovides
no support in this case. During the transition
from active topassive status, theà symbol is
shown as enlar ged and flashing. Once the sys‐
te m is passive, theà symbol is shown as

visual warning message.
The warning is not issued, or is stopped, when
th e driver gives confi rmation tothe sy stem:
R The driver steers theve hicle. R
The driver presses a steering wheel button or
operates Touch Control.
If Ac tive Steering Assist de tects that a sy stem
limit has been reached, a visual warning and
wa rning tone is issued.
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 neighbouring
lane is free (glance overth e shoulder).
Sy stem limits
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not su fficient tokeep the
ve hicle in the lane or todrive thro ugh exits.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
R The reis poor visibilit y,e.g. due tosno w,rain,
fo g, heavy spr ay,greatly varying light condi‐
tions or strong shado wsonthe car riag ewa y.
R There is glare, e.g. from oncoming traf fic,
di re ct sunlight or reflections. R
Insuf ficient road illumination.
R The windsc reen is dirty, mis ted up, damaged
or co vered in the vicinity of the camera, e.g.
by ast icke r.
R No, or se veral, unclear lane markings are
present for one lane, or the markings change
qu ickl y,e.g. in a const ruction area or junc‐
tions.
R The lane markings are wornaw ay, dark or
co vered up, e.g. bydirt or sno w.
R The dis tance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
R The road is nar row and winding.
R There are obs tacles on the lane or projecting
out into the lane, such as object mar kers.
The sy stem does not pr ovide assis tance in the
fo llowing conditions:
R On tight bends and when turning.
R When crossing junctions.
R Atroundabouts or tollst ations.
R When towing a trailer. Driving and parking

If no
vehicle is de tected in the adjacent lane and
a lane change is permit ted, the lane change
begins af terth e driver has activated the turn sig‐
nal indicator. This is shown tothe driver with a
green ar row 2 next tothesteering wheel sym‐
bol. The Lane change to the left message also
appears, forex ample. If Active Lane Change
Assi sthas been activated with the turn signal
indicator but a lane change is not immediately
possible, a gr eyarrow 1appears next tothe
st eering wheel symbol, which remains green.
When the lane change assis tance starts, the turn
signal indicator is automatically activated along
with the display in the multifunction displa y.If
th e assis tance graphic is shown when chang‐
ing lanes, the lane change display appears with
an additional ar rowpointing towa rdsth e adja‐
cent lane (/ page 238).
If a lane change is not possible, the ar row fades
out af ter a few seconds and a new lane change
must be initiated. An immediate lane change is
on lypossible on mo torw ay sections without
speed limits.
If th e sy stem is impaired, Active Lane Change
Assi stmay be cancelled. If it is cancelled, the
Lane change cancelled message appears inthe
multifunction display and a warning tone sounds. &
