and right), only focusing on the vehicle in front if
detected lane markings are not present.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide assis-
tance.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notes
If you fail to adapt your driving style, DISTRONIC
PLUS with Steering Assist and Stop&Go Pilot
can neither reduce the risk of an accident nor
override the laws of physics. It cannot take into
account road, weather or traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If
you are following a vehicle which is driving
towards the edge of the carriageway, your vehi-
cle 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 your vehicle.
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 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 vehicle
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 insufficient
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 windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R
no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R
the lane markings are worn away, dark or cov-
ered 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 detec-
ted
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 highly variable shade conditions on
the road
The system is switched to passive and no longer
assists you by performing steering interventions
if:
R
you actively change lane
R
you switch on the turn signal
R
you take your hands off the steering wheel or
do not steer for a prolonged period of time
i
After you have finished changing lanes,
Steering Assist and Stop&Go Pilot are auto-
matically active again.
Steering Assist and Stop&Go Pilot cannot pro-
vide assistance:
R
on very sharp corners
R
when towing a trailer
R
a loss of tyre pressure or a defective tyre has
been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS (
Y
page 207).
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 symbol
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 switch to passive mode.
DISTRONIC PLUS remains active.
