Active Distance Assist DISTRONIC 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
cannot take into account road, weather or traf-
fic conditions. Active Distance Assist
DISTRONIC 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.
Do not use Active Distance Assist DISTRONIC:
In road and traffic conditions which do not
R
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
On slippery road surfaces. Braking or accel-
R
erating could cause the drive wheels to lose
traction and the vehicle could then skid
In poor visibility, e.g. due to fog, heavy rain
R
or snow
Active Distance Assist DISTRONIC may not
detect narrow vehicles driving in front, e.g.
motorcycles, or vehicles driving in a staggered
formation.
In particular, the detection of obstacles can be
impaired if:
There is dirt on the sensors or anything else
R
covering the sensors
There is snow or heavy rain
R
There is interference by other radar sources
R
There are strong radar reflections, for exam-
R
ple in parking garages
If Active Distance Assist DISTRONIC no longer
detects a vehicle in front, Distance Pilot
DISTRONIC may unexpectedly accelerate to
the speed stored.
This speed may:
Be too high if you are driving in a turning
R
lane or an exit lane
Be so high when driving in the right-hand
R
lane that you overtake vehicles in the left-
hand lane
Be so high in the left lane that you pass
R
vehicles driving on the right
If there is a change of drivers, advise the new
driver of the speed stored.
