Principles of operation
Using a radar with a range of about 100 metres,
located at the front of the vehicle, this system
detects a vehicle running in front of your
vehicle.
It automatically adapts the speed of the vehicle
to that of the vehicle in front.
If the vehicle in front is running more slowly,
the system progressively reduces the speed of
your vehicle using just engine braking (as if the
driver had pressed the "-" button).
If your vehicle is too close to or approaching
too quickly the vehicle in front, the dynamic
cruise control is automatically deactivated.
The driver is then alerted by an audible signal,
accompanied by a message.
If the vehicle in front accelerates or changes
lane, the dynamic cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator
to the left (left hand drive) or the right (right
hand drive), to overtake a slower vehicle, the
dynamic cruise control allows your vehicle to
temporarily approach the vehicle in front to
assist the overtaking manoeuvre, though never
exceeding the programmed speed.
