tive Dis tance Assi stDISTRONIC maintains the
set speed on free-flowing roads. If vehicles in
front are de tected, the set dis tance is main‐
ta ined, if necessar y,until theve hicle comes to a
halt. The vehicle accelerates or brakes depend‐
ing on the dis tance totheve hicle in front and th
e set speed. The speed and dis tance tothe
ve hicle in front are set and sa ved on thesteering
wheel on vehicles without the Driving Assis tance
Pa ckage, in thera nge between 20 km/h and
200 km/h and, on vehicles with the Driving
Assis tance Package, in thera nge between
20 km/h and 210 km/h.
Other features of Active Dis tance Assi st
DISTRONIC:
R Adjusts the driving style depending on the
selected drive program (fuel ef ficient, com‐
fo rtable or dynamic) (/ page198)

and for braking in good time.
Sy stem limits
The sy stem may be impaired or may not function
in thefo llowing situations:
R In sno w,rain, fog, heavy spr ay, if there is
gl are, in direct sunlight or in great lyvarying
light conditions.
R Ifth ere is swirling dust, e.g. when driving off-
ro ad or on sandy sur faces. Driving and pa

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 (/ page249).
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 404))
% 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 adjust‐
ment made bythe sy stem may not alw ays be
suitable. In these situations the driver must
inter vene acco rdingly. &
WARNING Risk of accident in spi teof
ro ute-based speed adjustment
Ro ute-based speed adjustment might mal‐
function or be temp orarily una vailable in the
fo llowing situations:
R Ifth e driver does not follow the calcula‐
te dro ute
R If map data is not up todate or available
R Inroad con stru ction areas
R In bad weather or road conditions 248
