DISTRONIC PLU Siso nly an aid designe dto
assis tdriving. Th edrive rremain sfully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's spee dand for braking
in goo dtime.
DISTRONIC PLU Sdoes not react in particular
to:
R pedestrians
R stationar yobstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossin gtraffic
DISTRONIC PLUS may not detect narro wvehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on adifferen tline. Therefore,
always pay attention to traffic condition seven
when DISTRO NICP LUS is activated. Other-
wise ,you may fai ltorecognise danger sin
time, cause an accident and injure yourself
and others. G
Risk of accident
DISTRONI CPLUS cannot take account of road
and traffi cconditions. If DISTRONI Cdoesn ot
recognise or no longer recognises the vehicle
in front ,donot activate DI STRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes R
when changing to alane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on amotor-
way
DI ST RONIC PLUS otherwis emaintains the
current spee dset by you or accelerates up to
the set speed.
DI ST RONIC PLUS cannot take account of
weathe rconditions. Deac tivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could los etheir grip when
brakin goraccelerating .The vehicle could
star ttos kid.
R if the sensors are dirty or there is poo rvis-
ibility, e.g. due to snow, rain or fog. Dis-
tanc econtrol may be impaired.
Always pay attention to traffic conditions
even when DI STRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others.
The radar sensor syste misautomatically

If you want DISTRONIC PLUS to assis tyou,
the radar sensor system must be activated

Risk of accident
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by othe rmeans (e.g. in acar wash or
by towing).
You can activate DISTRONIC PLUS in the fol-
lowing circumstances:
R if the engine has been started and you have
been drivin gfor up to two minutes
R if the parkin gbrake is not applied
R if ESP ®
is acti vated
R if the transmission is in position D
R if the bonnet is closed
R if the driver' sdoor is closed and you shift
from Pto Dor your seat belt is fastened
R if the front-passenger door is closed
Activating while driving
When drivin gatspeeds below 30 km/h, you
can only acti vate DISTRONIC PLUS if the vehi-
cle in fron thas been detected and is shown
in the multifunction display. If the vehicle in
front is not shown in the multifunction display
and is no longe rbeing detected, because it
has changed lanes, for example, DISTRONIC
