all times.
If there is no vehicle in front,DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detectsthat the vehicle
in front has slowed down, it brakes your
vehicle. In this way, the distance you have
selected is maintained.
If DISTRONIC PLUS detectsafaster-moving
vehicle in front,itincreases the driving speed.
However, the vehicle is only accelerated up
to the speed you have stored.

If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 40 mph
(60 km/h)
RDISTRONIC PLUS is maintaining the
distance toavehicle in front
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not detectadanger
of collision
If these conditions are fulfilled, your vehicle
is accelerated. Acceleration will be
interrupted if changing lanes takes too long
or if the distance between your vehicle and
the vehicle in front becomes too small.
iWhen changing lanes, DISTRONIC PLUS

react appropriately to certain traffic
situations. This is the case if, while following
avehicle, DISTRONIC PLUS is active and you:
Rapproach or drive throughatraffic circle
RapproachaT-intersection
Rturn off atahighwayexit
Even if the vehicleinfront leaves the
detection range, DISTRONIC PLUS
