Mercedes-Benz S-Sedan 2015 Owners Manual - Manual (Page 207)

Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
R
when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else cover-
ing the sensors
R
snow or heavy rain
R
interference by other radar sources
R strong radar reflections, for example, in
parking garages
If DISTRONIC PLUS no longer detects a vehi-
cle in front, DISTRONIC PLUS may unexpect-
edly accelerate the vehicle to the stored
speed.
This speed may:
R be too high if you are driving in a filter lane
or an exit lane
R be so high in the right lane that you pass
vehicles driving on the left (left-hand drive
countries)
R
be so high in the left lane that you pass
vehicles driving on the right (right-hand
drive countries)
If there is a change of drivers, advise the new
driver of the speed stored.
