active cruise control

This systems allows, in addition to maintaining your vehicle's speed at a value that you have
defined, the inter-vehicle time you have selected between your vehicle and the one ahead to be
maintained.
Choice of the type of cruise control
If you want to use the standard cruise control,
it is possible to deactivate the active cruise
control in the the touch screen tablet.
F Place the cruise control thumb
wheel at "CRUISE".
F In the "Driving assistance"
menu, press this button; its
indicator lamp goes off.

This is confirmed by the display of
this symbol in the control.
Refer to the previous section for the
details of the operation of the standard
cruise control.
You can return to the active cruise
control at any time by pressing this
button again.
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 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 active 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 active
cruise control allows your vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, though never exceeding
the programmed speed.
