% 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
pr ov ide assis tance when driving outside the
centre of the lane toform are scue lane, for
ex ample.
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
gr ey inthe multifunction displa y.
Ste ering and touch de tection
The driver is requiredtokeep their hands on the
st eering wheel at all times and be able tointer‐
ve ne at any time tocor rect the course of the
ve hicle and keep it in lane. The driver must
ex pect a change from active topassive mode or
vice versa at any time. If
th e sy stem de tects that the driver has not
st eered theve hicle for a considerable period of
time or has remo vedth eir hands from thesteer‐
ing wheel, an optical warning is given firs t. Dis‐
pl ay 1 appears in the multifunction displa y.If
th e driver still does not steer theve hicle, or
gives no confirmation tothe sy stem, a warning
to ne sounds in addition tothe 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

and forst ay ing in lane. Before changing lanes,
th e driver must make sure that the neighbouring

Fu nction of Active Lane Change Assi st
% The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package.
Ac tive Lane Change Assi stsupports the driver
when changing lanes byapplying steering torque
if th e driver operates a turn signal indicator.
Assis tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
R You are driving on a mo torw ay orroad with
multiple lanes in the direction of tr avel.
R The neighbouring 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 80 km/h and
180 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, 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 (/ page247).
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. &
