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‐
cle in front, forve hicle speed and for bra

king in
good time. The maximum permissible speed also
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.

Function of route-based speed adjustment
%
The availability of thefo llowing function is
countr y-dependent.
When Dis tance Assist DISTRONIC is acti ve,th e
function adju ststh e speed depending on the
ro ute events ahead. Depending on the drive pro‐
gram selected, theve hicle negotiates thero ute
eve nt ahead in a fuel-s aving, com fortable or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
st ored speed. The set dis tancetotheve hicle
ahead, vehicles de tected ahead and speed
re strictions ahead are take n into account.
Ro ute-based speed adjustment can byconfig‐
ured in the multimedia sy stem (
→page 204). Ro
ute events ahead are:
RBends
RT-intersections, traf fic circles and tollst a‐
tions
RTu rnings and exits
% When theto llst ation is reached, Active Dis‐
ta nce Assist DISTRONIC adopts the speed as
th estored speed.
Also, the speed is reduced if the turn signal to
ch ange lanes is switch ed on and one ofthefo l‐
lowing situations is de tected:
RTu rning off at intersections
ROn slowing-down lanes
ROn lanes adjacent toslowing-down lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tointersections, traf fic cir‐
cles and sets of traf fic lights, as route-
based
speed adjustment does not brake theve hicle to
a st andstill.
Wi th active route guidance, thefirs t speed
adjustment is car ried out automaticall y.Ifth e turn signal indica
tor is switched on, the selected
ro ute isconfirmed and fur ther speed adjustment
is activated.
Speed adjustment is canceled in thefo llowing
cases:
RIf th e turn signal indicator is switched off
before thero ute event.
RIfth e driver depresses the accelera tor or
brake pedal during the process.
Sy stem limitations
Ro ute-based speed adjustment does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
re gulations and driving at a suitable speed.
In dif ficult ambient conditions (e.g. unclear
ro ads, nar rowlanes, wetro ad sur faces, snow or
ice) or when driving wi tha trailer, the speed
adjustment made bythe sy stem may not alw ays
be suitable. In these situations the driver must
inter vene acco rding ly.

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.

The driver is requ ired tokeep their hands on the
