DISTRONIC PLUS with Steering Assist

General notes
DISTRONIC PLUS Steering Assist aids you in
keeping the vehicle in the center of the driving
lane by means of moderate steering
interventions at speeds of 0 - 125 mph
(0 - 200 km/h).
DISTRONIC PLUS Steering Assist monitors
the area in front of your vehicle by means of
camera system :, at the top of the
windshield.
At speeds of more than 37 mph (60 km/h)
DISTRONIC PLUS Steering Assist focuses on
lane markings that are present.
At speeds of 0 - 37 mph (0 - 60 km/h)
DISTRONIC PLUS Steering Assist focuses on
the vehicle in front, taking into account lane
markings, e.g. when following vehicles in a
traffic jam.
DISTRONIC PLUS must be active in order for
the Steering Assist function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS Steering Assist can neither
reduce the risk of an accident nor override the
laws of physics. DISTRONIC PLUS Steering
Assist cannot take into account road,
weather or traffic conditions. DISTRONIC
PLUS Steering Assist is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
DISTRONIC PLUS Steering Assist does not
detect road and traffic 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. In the case of deviations in road
markings, beware of other road users, e.g.
cyclists, that are in the direct vicinity of 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 Steering Assist 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:
there is poor visibility, e.g. due to
R
insufficient 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
no, or several, unclear lane markings are
R
present for one lane, e.g. in a construction
area
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
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 lane
