Active cruise control
this systems allows the vehicle's speed to be
maintained at a value set by the driver.
In addition it allows (when circumstances
permit) an inter-vehicle time that you have
selected to be maintained between your vehicle
and the one in front.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 your
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 "-" b ut to n).
If your vehicle is too close to, or approaching
too quickly the vehicle in front, the cruise
control is automatically deactivated.
t
h
e
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
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.
Switching between the
types of cruise control
the choice between the "active" and "standard"
cruise control is made in the " Driving
assistance " menu.
th
e cruise control selection thumb wheel must
be in the "CR

th
e active cruise control operates by
day and at night, in fog or moderate
rainfall.th e system does not act on the braking
system, but works only with engine
braking.
th
e regulation range is limited: there will
no longer be any adjustment of speed if
the difference between the programmed
speed setting and the speed of the
vehicle in front becomes too high.
th
e selection of this system deactivates
the display of inter-vehicle time.
If the difference between the
programmed speed setting and the
speed of the vehicle in front is too
great, the speed cannot be adjusted:
the cruise control is automatically
deactivated.

Fluid specification
the brake fluid must conform to the
