Crossing vehicles: Active Distance Assist
DISTRONIC may mistakenly detect vehicles
that are crossing your lane. Activating Active
Distance Assist DISTRONIC at, for example, a
traffic light with crossing traffic could cause
your vehicle to pull away at the wrong time.
In such situations, brake if necessary. Active
Distance Assist DISTRONIC will then be deacti-
vated.
Active Distance Assist DISTRONIC with
Active Steering Assist
General notes
Active Distance Assist DISTRONIC with Active
Steering Assist aids you in keeping the vehicle in
the center of the driving lane by means of mod-
erate steering interventions in a speed range
from 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle by
means of multifunction camera :, which is
mounted at the top of the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
Active Steering Assist focuses on the vehicle in
front, taking into account lane markings, e.g.
when following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Active Steering Assist focuses on clear lane
markings (left and right), focusing on the vehicle
in front only if clear lane markings are not pres-
ent.
If these conditions are not present, Active Steer-
ing Assist cannot provide assistance.
Active Distance Assist DISTRONIC must be
active in order for the function to be available.
Important safety notes
Active Distance Assist DISTRONIC with Active
Steering Assist can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. Active Distance
Assist DISTRONIC with Active Steering Assist
cannot take into account road, weather or traffic
conditions. Active Distance Assist DISTRONIC
with Active Steering Assist is only an aid. You are
responsible for maintaining a safe distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Active Distance Assist DISTRONIC with Active
Steering Assist 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 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 traffic pylons at roadworks 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.
Active Distance Assist DISTRONIC with Active
Steering Assist cannot continuously keep your
vehicle in lane. In some cases, steering inter-
vention 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 heavy 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 windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
R
there are no or several unclear lane markings
for one lane, e.g. roadworks
R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
