In the event of the presence of a
vehicle detected by the radar, if the
speed selected is much higher than
the speed of that vehicle, the system
is not activated and the alert message
"Activation not possible, conditions
unsuitable" is displayed until driving
conditions are safe to allow activation of
the system.

Modification of the inter-vehicle
distance
Press button 6 to choose a new inter-vehicle
distance setting from the 3 available (" Close",
" Normal ", "Distant ").
This value remains in memory, whatever the
state of the system.
It is possible to exceed the speed setting
temporarily by depressing the accelerator
pedal.
Then simply release the accelerator pedal to
return to the programmed speed.
If the speed setting is unintentionally exceeded,
descending a steep hill for example, the speed
setting in the instrument panel flashes as a
warning.

Comments
No vehicle detected:
the system operates as a standard cruise control.
Detection of a vehicle, at the limit of the range of the radar:
the system operates as a standard cruise control.
"SPEED ADJUSTED" Detection of a vehicle that is too close or running at a speed lower than your
vehicle's cruise speed setting.
The system uses engine braking to slow your vehicle and then hold it at the speed of
the vehicle in front so as to maintain the programmed inter-vehicle time.
The regulation range is limited to a maximum difference of 20 mph (30 km/h)
between the speed setting and the speed of the vehicle ahead.
"SPEED ADJUSTED" When the adjusted speed reaches the control limit (speed setting - 20 mph
(30
km/h)), the adjusted speed flashes together with the speed setting, to signal that
automatic deactivation of the system is imminent.
"Cruise control
paused" If the system exceeds the limit of speed adjustment possible by the system and
in the absence of any reaction by the driver (operation of the direction indicator,
change of lane, reduction of the speed of the vehicle), the system is automatically
paused.
The display of the deactivation message is accompanied by an audible signal.
Driving situations and associated alerts
The table below describes the alerts and the messages displayed for the different driving situations.
The display of these alerts is not sequential.

When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. The message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the system be
reactivated by pressing button 2 or 3,
which will make the current speed of
your vehicle the new cruise speed
setting, rather than by pressing button 4
(on/pause) which reactivates the system
using the old cruise speed setting,
which may be very different from the
current speed of your vehicle. The dynamic cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
The system is paused automatically:
-

i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle
and the vehicle in front,
-

i
f the system does not slow the vehicle
enough to continue to maintain a safe
distance, for example when descending a
steep hill.
Limits of operation
As the radar's field of view is quite narrow, it is
possible that the system may not detect:
The cruise control does not take account of:
-
s

tationary vehicles,
-

v
ehicles driving in the opposite direction.
-

v
ehicles of reduced width, such as
motorcycles,
-

v
ehicles not running in the middle of the
lane,
-

v
ehicles entering a corner,
-

v
ehicles changing lane at the last moment.
The regulation range is limited to a maximum
difference of 20 mph (30 km/h) between the
speed setting and the speed of the vehicle in
front. Above this, the system goes into pause if
a safe distance is not maintained.
Severe weather conditions (very heavy
rain, accumulations of snow in front
of the radar) can inter fere with the
operation of the system, resulting in
the display of the message "SYSTEM
INACTIVE: Visibility reduced". The
function remains unavailable until the
message disappears.

When the cruise control is paused,
it can only be reactivated when all of
the safety conditions are met. The
message "Activation not possible,
conditions unsuitable" is displayed while
reactivation is not possible.
Wait until the speed of the vehicle
is close to the speed setting before
reactivating the system - by pressing
button 2 or 3 - in order to set your
current speed as the new speed setting.

The speed is then displayed in the instrument
panel as the new speed setting.
As a precaution, it is recommended that
you select a cruise speed setting close
to the current speed of your vehicle, so
as to avoid any sudden acceleration or
deceleration of the vehicle.

section.

+ "Take back control of the
vehicle"
The driver should take control of the vehicle by accelerating or
braking, depending on the circumstances.
+ "Take back control of the
vehicle"
The system cannot manage the critical situation alone
(emergency braking of the target vehicle, rapid insertion of
another vehicle between the two vehicles).
The driver must immediately take back control of the
vehicle.
or "Activation not possible,
conditions unsuitable"
The system refuses to activate the cruise control (speed outside
the operating range, winding road).
or according to the inter-vehicle
distance selected and the actual
distance from the target vehicle "Cruise control paused"
(for a few seconds)
The system has brought the vehicle to a complete stop and is
holding it immobilised.
The driver should accelerate to move off again.
The cruise control remains paused until the driver reactivates it
with the speed of the vehicle above 18 mph (30 km/h).
