Operating principle of adaptive cruise
controlNo vehicle detected in front – open road
driving
Adaptive cruise control operates like a cruise
control system. The desired speed that was set is
maintained constantly.
Vehicle detected in front – driving in traffic
If a vehicle travelling ahead of you in the same lane
is detected as driving slower than the selected
desired speed, adaptive cruise control will
automatically maintain a set distance from the
vehicle in front.
If the vehicle in front stop s, adaptive cruise control
will slow your vehicle down to a stop provided this
is possible within the cont rol limits of the system.
Adaptive cruise control actively keeps your vehicle
at a standstill.
If the vehicle in front drives off, automatic speed
control and distance control can be resumed.
