ruption, the system will no longer automatically 
activate the vehicle brakes, which means the 
driver must intervene and resume manual brak-
ing. You should then reactivate the system only 
when you are fully aware of the prior speed and 
distance settings.

Active cruise control may brake when you 
reduce the stored desired speed; however, the 
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition, 
active cruise control is fully switched off, too, 
and any settings you have selected are can-
celed.
Unexpected lane change
If a vehicle in front of you is behind a stopped 
vehicle and unexpectedly changes lanes, you 
must react yourself, as the system does not 
react to stopped vehicles.
Swerving vehicles
When a vehicle swerves out of adjacent lanes 
into your lane, the system does not detect the 
vehicle until it is completely in your lane.
When a vehicle ahead suddenly swerves 
into your lane, the system may not be able 
to restore the selected distance automatically. 
This also applies to great differences in speed 
between your vehicle and vehicles ahead, e.g. 
when quickly approaching a truck. Once the 
system has established that a vehicle is indeed 
in front of you, it will indicate that you must 
brake and/or maneuver the vehicle yourself. 
Take action yourself, otherwise there is a risk of 
an accident.

Behavior in curves
If the selected desired speed for a curve is too 
high, the system reduces the speed within a 
curve. However, it cannot detect curves in 
advance. Therefore, select a suitable speed at 
the start of a curve.
Because of the limited range of the system, it is 
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to 
the driver to select a speed that is prudent in 
view of the curves and terrain of the roadway.
In approaching a curve, it is possible that active 
cruise control might react briefly to a vehicle in 
the adjacent lane. In addition, the system can 
sense if your vehicle is in a curve and may not 
accelerate. If your vehicle decelerates in either 
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
