Driving
The active cruise control is switched onmanually: it requires that the speed of the vehicle
be between 25 mph (40 km/h) and 90 mph (15 0 km / h), as well as the engagement of:


- at least four th gear with a manual gearbox,

- second gear with an electronic or automatic gearbox in manual mode,

- position A
with an electronic gearbox or Dwith an automatic gearbox.


General points
The active cruise control can above be pausedmanually with the control, or automatically:
- b
y pressing the brake or clutch pedal,
- in the event of operation of the DSC, for
safety reasons,
- in the event of an action of the electric
parking brake control,
- when an inter-vehicle time threshold isreached (calculated according to therelative speeds of your vehicle and the
vehicle in front and the inter-vehicle time setting chosen),
- when the distance between your vehicle
and the one in front becomes to small,
- when the speed of the vehicle in front is to
low,
- when the speed of your vehicle becomes
too low.


The active cruise control cannot in any
circumstances replace the obser vation of speed limits, nor the the vigilanceand responsibility of the driver. It is recommended that you always keepyour feet close to the pedals.



If the speed setting selected is above93 mph (15 0 km/h), the system switches
to normal cruise control operation(a message appears in the instrument panel).
Switching off the ignition cancels any
programmed value, and the inter-vehicle time is reset to 2 seconds.

As a precaution, it is recommended that
you
select a speed setting close to the current
speed of your vehicle.


If the active cruise control has not beenswitched on, pressing this button hasno effect.

Driving

In the event of the presence of a vehicle detected by the radar, if thespeed selected is much higher than the speed of that vehicle, the systemis not activated and the aler t message "Activation not possible, conditions unsuitable" is displayed until driving conditions are safe to allow activation of the system.
Exceeding the programmed
speed
It is possible to exceed the programmed speed
temporarily by depressing the accelerator pedal. Simply release the accelerator pedal to return to the programmed speed.
If the programmed speed is unintentionally
exceeded, descending a steep hill for example,
the speed setting in the instrument panel
flashes as a warning. The in
formation is grouped together in the
instrument panel.

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 cruise control using the old cruise speed setting, which may be very different from the current speed of your vehicle.

"
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.
"
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.

180
Driving
The active cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle looses speed slowly, as when releasingthe accelerator pedal.
The system is paused automatically:
- if the vehicle in front slows down to much
or too suddenl
y, and the driver does notbrake,
- if a vehicle comes between your vehicle and the vehicle in front,
- if 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:
Th
e cruise control does not take account of:


- stationary vehicles,

- vehicles driving in the opposite direction.

- vehicles o
f reduced width, such as
motorcycles, for example,


- vehicles not runnin
g in the middle of the lane,


- ve
hicles entering a corner,


- vehicles changing lane at the last moment.
The re
gulation range is limited to a maximum
difference of 20 mph (30 km/h) between thespeed setting and the speed of the vehicle ahead. Above this, the system goes into pause
if a safe distance is not maintained.
Severe weather conditions (very heavy rain, accumulations of snow in frontof the radar) can interfere with theoperation of the system, resulting inthe display of the message "SYSTEMINACTIVE: Visibility reduced". Thefunction remains unavailable until themessage disappears.

Driving
In the event of a fault with the active cruisecontrol, you are alerted by an audible signal
and display of the message message "Drivingaid functions fault".
Have the system checked by a CITROËN
dealer or a qualified workshop.
When the cruise control is working, takecare if making a maintained press onone of the cruise control programmedspeed modification buttons: this can lead to a very quick change in thespeed of your vehicle. Do not use the active cruise control onslippery surfaces or in heavy traffic. When descending a steep hill, thecruise control may not be able to prevent the vehicle from exceeding theprogrammed speed.When ascending a steep hill or whentowing, it might not be possible to attainor maintain the programmed speed. The use of mats not approved by CITROËN may inter fere with the
operation of the cruise control. To avoid any risk of jamming the pedals:- ensure that mats are positioned correctly, - never fit one mat on top of another.


Operating fault


The operation of the radar, located in the front bumper, may be disturbed by accumulations of grime (dust, mud...) or in certain weather conditions (snow,ice...).
The message "SYSTEM INACTIVE:Visibility reduced" is displayed to signal that the system has been put intostandby.
Clean the front bumper regularly.

Driving





Collision risk alert
System providing a warning to the driver that their vehicle is at risk of collision with the vehicle in front.

The collision risk aler t system can be activated
or deactivated b
y the driver.
From the secondary page of the " Drivingassistance" menu:)
select the " Vehicle settings
" menu, )
check the "Collision risk alert" line andconfirm.


This system has been designed to improve driving safety.
It is the responsibility of the driver to keep a constant check on the state of the traffic, to assess the relative speedand distance of other vehicles. The collision risk aler t system can never replace the vigilance and responsibilityof the driver.


This system operates from 20 mph (30 km/h), only when other vehicles are running in the same direction as your vehicle; the system does not detect stationary objects. A radar is fitted at the front of the vehicle.
The aler t thresholds determine how
you want to
be aler ted to the presence of a vehicle running
in front of you.
You can choose from three thresholds:


- 1: "Distant", to be given an early alert
(cautious driving).

- 2: "Normal".

- 3: "Close", to be given a later aler t (sportydriving).



Setting the thresholds for
the alert
This function can be deactivatedpermanently by a CITROËN dealer or aqualified workshop.

From the secondary page o
f the "Driving assistance
" menu: )select the "Vehicle settings" menu,)check the " Collision risk alert
" line, )press on the magnifying glass, )modify the aler t threshold and press on"Finish" to memorise the threshold andleave the menu.
