Fu
nction of Active Speed Limit Assi st%
The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package. If a
change in the speed limit is de tected and
au tomatic adoption of speed limits is activated,
th e new speed is automatically adop ted as the
st ored speed (/ page 285). 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 according tothe speed
permitted within the urban area. The speed limit
display in the Instrument Display is alw ays upda‐
te d 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 mo torw ay),th ere com‐
mended speed is au tomatical lyadop ted as the
st ored speed. The sy stem uses the speed stored
on an unlimited stre tch of road as there com‐
mended speed. If you do not alter thestored
speed on an unlimited stre tch of road, there c‐
ommended speed is 130 km/h.
If Ac tive Dis tance Assi stDISTRONIC has been
put into passi vemode bypressing the accelera‐
to r pedal, only speed limits which are higher
th an the set speed are adop ted.
Ac tive Speed Limit Assi stis only an aid. The
driver is responsible forke eping a safe dis tance
from theve hicle in front, forve hicle speed and
fo r braking in good time. The maximum permissi‐
ble speed also depends on factors su chasthe
ro ad sur face and traf fic conditions. Sy
stem limits
Te mp orary speed restrictions (e.g. for a cer tain
time or due towe ather conditions) cannot be
proper ly detected bythe sy stem. The maximum
permissible speed applying toave hicle with a
trailer is not de tected bythe sy stem. In these sit‐
uations you must adjust your speed yourself. &

Fu
nction of route-based speed adaptation %
The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package.
When Active Dis tance Assi stDISTRONIC is acti‐
va ted, theve hicle speed will be adjus ted accord‐
ingly tothero ute events ahead. Depending on
th e drive prog ram selected, theve hicle negoti‐
ates a route event ahead in a fuel-s aving, com‐
fo rtable or dynamic manner. When thero ute
eve nt has been passed, theve hicle accelerates
again tothestored speed. The set dis tance to
th eve hicle in front, vehicles de tected ahead and
speed restrictions ahead are take n into account.
Ro ute-based speed adap tation can be config‐
ured in the multimedia sy stem (/ page 238).
The following route events are take n into
account:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
( / page 413)) %
When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed.
Also, the speed is reduced if the turn signal indi‐
cator tochange lanes is swit ched on and one of
th efo llowing situations is de tected:
R Turning off at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts
and traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
When route guidance is active, thefirs t speed
adjustment is car ried out automaticall y.Ifthe
turn signal indica tor is switched on, the selected
ro ute is confirmed and fur ther speed adjustment
is activated. Speed adjustment is cancelled in
thefo llowing
cases:
R Ifth e turn signal indicator is switched off
before thero ute event.
R Ifth e driver depresses the accelerator or
brake pedal during the process.
Sy stem limits
Ro ute-based speed adap tation 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 conditions, forex ample unclear roads,
lane nar rowing, wetro ad sur faces, snow or ice,
or when driving wi tha trailer, the speed adap ta‐
tion made bythe sy stem may not alw ays be suit‐
able. In these situations the driver must inter‐
ve ne acco rding ly. &

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‐

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 is
issued and a warning tone sounds.
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,

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‐

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

Swipe left or right tochange the articulation

% The maximum articulation angle depends on
the length of the trailer. This is calculated by
th e sy stem bydriving theve hicle forw ards,
including cornering. Before the length of the
trailer has been calculated, the maximum
articulation angle is appr oximately 23°. The
longer the trailer is, the higher the maximum
articulation angle (max. appr oximately 60°). #
