Pay particular attention in the following traffic
situations:
R cornering, entering and exitin gabend
R vehicles which are not driving in the middle
of their lane
R other vehicles changin glane
R narrow vehicles
R obstructions and stationary vehicles
R crossin gvehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, entering and exiting abend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles which are not driving in the mid- dle of their lane DISTRONIC PLUS may not detect vehicles
which are not driving in the middle of their Driving systems

lane. The distanc
etothe vehicle in front will
be too short.
Other vehicles changing lane DISTRONIC PLUS has not detected the vehi-
cle cuttin ginyet. The distanc etothis vehicle
will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the carriageway
because of its narrow width .The distanc eto
the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brak
efor obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns acorner and reveals
an obstacle or stationary vehicle, DISTRONIC PLUS will not brak efor these.
Crossin gvehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossin
gyour lane. Activat-
ing DISTRONIC PLUS at traffic light swith
crossin gtraffic ,for example, could cause
your vehicle to pull away unintentionally.
DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steerin
gAssist and
Stop&Go Pilot aids you in keeping the vehicle in the centr eofthe drivin glane by mean sof
moderate steerin ginterventions in aspeed
rang efrom0-2 00 km/h.
It monitor sthe area in front of your vehicle by

In
as peed range from 0-60km/h,Stop&Go
Pilotf ocuses on the vehicle in front, taking
into account lane markings, e.g. when follow- ing vehicle sinatraffic jam.
At speedsofm ore than 60 km/h ,Steering
Assist focuses on detected lane markings
(left and right), only focusing on the vehicle in
front if detected lane markings are not pres-
ent.
If these conditions are not present, Steering
Assist and Stop&Go Pilotc annot provide
assistance.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt yourd riving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotc an neither reduce the risk of
an accident nor override the lawsofp hysics.
It cannot take into account road, weather or
traffic conditions. DISTRONIC PLUS with
Steering Assist and Stop&Go Pilotiso nly an
aid.Y ou are responsible for the distance to
the vehicle in front, for vehicle speed,f or
braking in good time, and for staying in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotd oes not detect road and traf-
fic conditions and does not detect all road
users. If you are following avehicle which is
driving towards the edge of the carriageway,
yourv ehicle could come into contact with the
kerb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that
are directly next to yourv ehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g.
after intentionally driving over alane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotc annot continuousl ykeep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it
does not leave the lane.
The support offered by the system may be
impaired if:
R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windscree nisdirty, misted up, dam-
aged or covered, for instance by asticker,

R no, or several ,unclea rlane markings are
present for one lane, e.g. in aconstruction
area
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highlyv ariable shade conditions
on the road
The system is switched to passive and no lon-
ger assists you by performing steering inter-
ventions if:
