braking in good time and for staying in your
lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traf-
fic conditions. If you are following a vehicle
which is driving towards the edge of the road,
your vehicle could come into contact with the
curb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that
are directly next to your vehicle.
Obstacles such as building site huts on the
lane or projecting out into the lane are not
detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep 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 provided by the system can be
impaired if:
there is poor visibility, e.g. due to insuffi-
R
cient illumination of the road, or due to
snow, rain, fog or spray
there is glare, e.g. from oncoming traffic,
R
the sun or reflections (e.g. when the road
surface is wet)
the windshield is dirty, fogged up, damaged
R
or covered, for instance by a sticker, in the
vicinity of the camera
there are no, several or unclear lane mark-
R
ings for a lane, e.g. in areas with road con-
struction work
the lane markings are worn away, dark or
R
covered up, e.g. by dirt or snow
the distance to the vehicle in front is too
R
small and the lane markings thus cannot be
detected
Driving systems
the lane markings change quickly, e.g.
R
lanes branch off, cross one another or
merge
the road is narrow and winding
R
there are strong shadows cast on the road
R
The system is switched to passive and no lon-
ger assists you by performing steering inter-
ventions if:
you actively change lane
R
you switch on the turn signal
R
take your hands off the steering wheel or do
R
not steer for a prolonged period of time
i
Steering Assist and Stop&Go Pilot are
activated again automatically after a lane
change is completed.
Steering Assist and Stop&Go Pilot do not pro-
vide any support:
on very sharp corners
R
when a loss of tire pressure or a defective
R
tire has been detected and displayed
Pay attention also to the important safety
notes for DISTRONIC PLUS (
The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you
have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot are
switched to passive. DISTRONIC PLUS
remains active.
