Operation Manual

override the laws of physics. It cannot take
account of road, weather and 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 your lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions. If you are following a vehicle which is
driving towards the edge of the road, your vehi-
cle 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 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 system may be impaired or may not function
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 reflections (e.g. when the road surface
is wet)
R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
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 strong shadows cast on the road
The syst
em 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
take your hands off the steering wheel or do
not steer for a prolonged period of time
i
Steering Assist and Stop&Go Pilot are acti-
vated again automatically after a lane change
is completed.
Steering Assist and Stop&Go Pilot do not pro-
vide any support:
R
on very sharp corners
R
when a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS (
Y page 187).
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 are switched to passive.
DISTRONIC PLUS remains active.
