Functions and activation conditions
The distance control assistant controls the
speed and supports you in automatically
maintaining the distance from a vehicle
detected in front. If there is no vehicle in front,
the distance control assistant operates in the
same way as cruise control in the speed range
between 15 and 90 km/h. If a vehicle is
detected in front, it operates in the speed
range between 0 and 90 km/h.
If the distance control assistant detects a
vehicle in front driving at a slower speed, your
vehicle is slowed and the specified minimum
distance selected is maintained.
The distance control assistant brakes the
vehicle with the continuous brake if:
the vehicle exceeds the set speed, includ-
R
ing the set speed tolerance, e.g. on a down-
hill gradient
a slower vehicle in front is detected
R
When the continuous brake slows the vehicle,
the à indicator lamp lights up in the instru-
ment cluster.
The distance control assistant may also brake
the vehicle using the service brake in order to
maintain the specified minimum distance. If
the vehicle in front is no longer detected, e.g.
if it changes lane, your vehicle will accelerate
up to the set speed.
