Ac tive Steering Assist
Function of Active Steering Assist
Ac tive Steering Assist is only available for
ve hicles with the Driving Assistance Pack‐
age.
RAc tive Steering Assist is operational at
speeds up to130mp h(210 km/h) and helps yo
uto stay inthe center of the lane by
means of moderate steering inter ventions.
RIt uses theve hicle in front and the lane mark‐
ings as a refere nce depending on the driven
speed.
RAc tive Steering Assist requiresyou as the
driver, tokeep your hands on thesteering
wheel at all times so that you are able to
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
RAc tive Steering Assist can be overridden at
any time bysteering theve hicle yourself.
RWhen the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
Sy stem limitations of Active Steering Assist
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.
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
the active topassiv e
st at
us, theè sym‐
bol is shown as enlar ged and flashes yello w.
Once the sy stem is passive theè symbol is
shown as gr ayinthe multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
RIfth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,
ra in, fog or heavy spr ay.
RIfth ere is glare, e.g. from oncoming traf fic,
dire ct sunlight or reflection from other vehi‐
cles (e.g. if thero ad is wet).
RIfth e windshield is dirty, fogged up, damaged
or co vered, for ins tance byast icke r,in the
vicinity of the camera.
RIf no, or se veral, unclear lane markings are
present for one lane, e.g. in a construction
area.
RIf th e lane markings are wornaw ay, dark or
co vered up, e.g. bydirt or sno w.
RThe distance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.

RIfth e lane markings change quickl y,e.g.
lanes branch off, cross one ano ther or

RThe road is nar row and winding.
RIfth ere are highly variable shade conditions
on thero ad.
RIfth ere are obs tacles such as object mar kers
on the lane or projecting out into the lane.
The sy stem does not pr ovide assis tance in the
fo llowing conditions:
ROn very sharp bends.
RWhen towing a trailer.
RIfyo u act ively change lane without switch ing

activated.
#If indicator lamp 1is off: press button 2.
Fu nction of Active Lane Change Assi st
Ac tive Steering Assist is only an aid. You are
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, make sure
that the neighboring lane is free
(shoulder view).
% The availability of thefo llowing function is
countr y-dependent.
Ac tive Steering Assist remains active even if the
turn signal indica tor is switched on. Active Steer‐
ing Assist then assists the driver when changing
lanes byapplying steering torques toinitiate the
lane change.
Assis tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
RYou are driving on a free wayor high-speed
multi-lan emajo rro ad with multiple lanes in
th e direction of tr avel.
RThe neighboring lane is free and separated
bya broken lane marking.
RThe driven speed is between 50 mph
(80 km/h) and 110mp h(1 80 km/h).
RThe turn signal indicator is switched on for
longer than two seconds.
If th e sy stem is impaired, Active Lane Change

Ac tive Steering Assist requ ires you as the driver,
to keep your hands onthesteering wheel at all
times so that you are abletointer vene at any
time tocor rect the course of theve hicle and
