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 vehi-
cle in front driving at a slower speed, your vehi-
cle is slowed and the specified minimum dis-
tance selected by you is maintained.
The distance control assistant brakes the vehi-
cle with the continuous brake if:
R
the vehicle exceeds the set speed, including
the set speed tolerance, e.g. on a downhill
gradient
R
a slower vehicle in front is detected
When the continuous brake slows the vehicle,
the
Ã
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.
The distance control assistant cannot be acti-
vated or is deactivated automatically if:
R
you are driving slower than 15 km/h on roads
with more than a 10% downhill/uphill gradi-
ent
R
you are driving slower than 5 km/h and a
vehicle in front is not detected
R
you shift the transmission into neutral for
more than approximately 5 seconds
R
you select the reverse gear

complete
If the distance control assistant is deactivated
automatically, a warning tone sounds.

vated, the on-board computer will display
- - .- km/h in grey.

ted if:
