Variable SPEEDTRONIC is automatically
deactivated if:
R

and the maximum speed (

Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,

You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown).
DISTRONIC PLUS
Important safety notes
G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R
pedestrians
R
stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R
oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
