ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available with‐
out active route guidance. Notall information
and traf fic situations can be fore seen. The qual‐
ity depends on the map data.
ECO Assist is only an aid. The driver is responsi‐
ble forke eping a safe dis tance from theve hicle
in front, forve hicle speed and for braking in
good time. The driver must be ready tobrake at
all times ir respective of whe ther the sy stem
inter venes.
The sy stem may be impaired or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsuf ficient illu‐
mination of thero ad, high lyvariable shade
conditions, rain, sno w,fog or heavy spr ay.176

Fu
nction of Active Speed Limit Assi st
If a change in the speed limit of 20 km/h or
more is de tected and auto matic adoption of
speed limits is activated, the new speed limit is
automatically adop ted as thestored speed
(/ page 231).
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 unlimited
st re tch of road (e.g. on a mo torw ay),th ere com‐
mended speed is auto maticallyadop 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. Obser
vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 198).
Sy stem limits

Speed limits bel ow20 km/h are not auto mati‐
cally adop tedby the sy stem as thestored speed.
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.

The speed adop tedby Active Speed Limit
Assi stmay be too high or incor rect in some

nction of route-based speed adaptation
When Active Dis tance Assi stDISTRONIC is acti‐
va ted, theve hicle speed will be adap ted accord‐
ingly tothero ute events ahead. Depending on
th e drive prog ram selected, theve hicle negoti‐
ates a route event ahead in an economical, 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.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia sy stem
(/ page 218). 216
Driving and pa rking

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
Information )
% 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 adap tation 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.
The speed adap tation made bythe sy stem may
not alw ays be suitable, particular lyin thefo llow‐
ing situations:
R thero ad's course not clear lyvisible
R road nar rowing
R varying maximum permissible speeds in indi‐
vidual lanes, forex ample at tollst ations R

R when towing a trailer
In these situations the driver must inter vene

Ro ute-based speed adap tation can malfunc‐
