If th eve hicle should ne verex ceed a speci/c
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
Yo u do this by limiting the speed between
160 km/h and 240 km/h in the multimedia sys-
te m (/ page 232).
Shortly before the set speed is reached, it
appears in the Instrument Displa y.When you con-
/rm the message, display messages no longer
appear until you switch o. theve hicle. The speed
will only be displ ayed again once theve hicle has
been restar ted or if the set speed is changed.
The permanent limi ter does not switch topassive
mode even during kickdown and the driven speed
re mains below the set speed. Se

Ac tive Distance Assist DISTRONIC maintains the
set speed on free-0owing roads. If vehicles in
front are de tected, the set distance is maintained,
if necessar y,until theve hicle comes toa halt. The
ve hicle accelerates or brakes depending on the
distance totheve hicle in front and the set speed.
The speed and distance totheve hicle in front are
set and sa ved using the steering wheel.

WARNING
ARNING Risk of accident due toActive
Speed Limit Assist ada pting theve hicle's
speed
The speed adop tedby Active Speed Limit
Assist may be too high or incor rect in some
individual cases, such as:
R at speed limits below 20 km/h
R inwe t conditions or in fog
R when towing a trailer #
Ensure that the driven speed complies
with tra1c regulations. #
Adjust the driving speed tosuit cur rent
tra1c and weather conditions. F F

ation
When Active Distance Assist DISTRONIC is acti va-
te d, theve hicle speed will be adap ted accordingly
to thero ute events ahead. Depending on the drive prog
ram selected, theve hicle neg otiates a route
ev ent ahead in an economical, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-
tions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 238).
The following route events are take n into account:
R Bends
R T-junctions, roundabouts and toll stations
R Turns and exits
R Tra1c jams ahead (only with Live Tra1c Infor-
mation )
% When theto ll station is reached, Active Dis-
ta nce Assist DISTRONIC ado ptsth e speed as
th e stored speed.
Also, the speed is reduced if the turn signal indi-
cator tochange lanes is switched on and one of
th efo llowing situations is de tected:
R Turning o. 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
tra1c lights, as route-based speed adap tation
does not brake theve hicle toa standstill.
When route guidance is active, the /rst speed
adjustment is car ried out automaticall y.Ifth e turn
signal indicator is switched on, the selected route
is con/rmed and fur ther speed adjustment is acti-
va ted.
Speed adap tation is cancelled in thefo llowing
cases:
R Ifth e turn signal indicator is switched o.
before thero ute event.
R Ifth e driver depresses the accelerator or
brake pedal during the process.
