WARNING Risk of an accident despite
Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traf fic situa‐
tions.
In addition, thesteering support of Evasive
St eering Assist is generally not suff icientto
av oid a collision.
In such cases Evasive Steering Assist can:
Rgive an unnecessary warning or pr ovide
assis tance
Rnot give awa rning or not pr ovide assis‐
ta nce
#Alw ays pay careful attention tothe traf‐
fi c situation; do not rely on Ev asive
St eering Assist alone.
#Be ready tobrake and take evasive
action if necessar y.
#Preve ntthe assis tance byactively steer‐
ing in non-critical driving situations.
#Drive at an appropriate speed if pedes‐
trians are close tothe path of your vehi‐
cle.
Also obser vethe sy stem limitations of Evasive
St eering Assist.

Function of Active Speed Limit Assi st
%
The availability of thefo llowing function is
countr y-dependent.
If a change in the speed limit is de tected and
Ac tive Dis tance Assist DISTRONIC is acti vated,
Ac tive Dis tance Assist DISTRONIC assumes this
new speed as thestored speed.
The driven speed is adjus ted when theve hicle is
le ve l with the traf fic sign at the latest. In the
case of signs indicating entry into an urban area,
th e speed is adap ted beforehand. The speed
limit display in the Instrument Display is alw ays
updated when theve hicle is le vel with the tra ffic
sign.
If th ere is no speed restriction on an unlimi ted
st re tch of road (e.g. on a free way), there com‐
mended speed is adop ted as thestored speed.
The sy stem uses the speed stored on an unlimi‐
te dstre tch of road as there commended speed.
If yo udo not alter thestored speed on an unlimi‐
te dstre tch of road, there commended speed is
80 mph (130 km/h).
If Ac tive Dis tance Assist DISTRONIC has been
put into passive modebypressing the accelera‐
to r pedal, only speed limits which are higher
th an the set speed are adop ted. Ac
tive Speed Limit Assi stcan be configu red in
th e multimedia sy stem (→page 235).
Ac tive Speed Limit Assi stis only an aid. The
driver is responsible forth e dis tance
totheve hi‐

depends on factors such asthero ad sur face and
traf fic conditions.
Sy stem limitations
Te mp orary speed restrictions (e.g. for a cer tain
time or due towe ather conditions) cannot be
proper lyde tected bythe sy stem. The maximum
permissible speed applying for a vehicle with a
trailer is not de tected bythe sy stem. In these sit‐
uations you must adjust your speed yourself.

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

Ifth 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

st eer theve hicle himself or herself, or still has
not take n hold of thesteering wheel, a repeated
wa rning tone sounds in addition tothe visual

control of theve 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).
Sy stem 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

St eering Assist cann otprov ide the driver with
st eering assis tance at traf fic circles, T-intersec‐
