Driving
The system is reactivated automaticallyevery time the engine is star ted by the driver.
Reactivation
Press this button again.
Operating fault
Have it checked by a CITROËN dealer or aqualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall.
All of the instrument panel warning lamps come on.
Depending on version, an alert message may
also be displa
yed, asking you to place the gear
selector lever in position Nand put your foot on
the brake pedal.
It is then necessar
y to switch off the ignition
and star t the engine again using the "START/STOP" button.In th
e event of a fault with the system, this warning lamp comes
on continuously.
The system is active again; this is confirmed by the indicator lamp in thebutton going off and illumination of
this symbol.
The Stop & Start system makes use of advanced technology. For any work onthe system go to a qualified workshop with the skills and equipment required, which a CITROËN dealer is able toprovide.
Before doing anything under the bonnet,deactivate the Stop & Start system toavoid any risk of injury resulting fromautomatic operation of STA R T m o d e .
Maintenance
This system requires a 12 V battery with a special specification and technology (reference numbers available from CITROËN dealers).
Fitting a battery not listed by CITROËN introduces the risk of malfunction of
the system.
For charging, use a 12 V charger and do not
reverse the polarity.

Cruise control
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control system cannot, in any circumstances, replace the need to obser ve speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver.
You are advised to keep your feet near the pedals at all times.
Th
e cruise control is switched on
manually: it
requires a minimum vehicle speed of 25 mph
(40 km/h) and engagement of:
- at least four th gear on a manual gearbox,
- second gear on an electronic or automatic gearbox, in manual driving mode,
- position A
on an electronic gearbox or D
on an automatic gearbox.

Displays in the instrument panel
Switching off the ignition cancels any programmed speed value. Th
e cruise control is paused
manually or
by pressing the brake or clutch pedal or
on triggering of the ESP system for safety
reasons.
It is possible to exceed the programmed speed
temporarily by pressing the accelerator pedal.
To return to the programmed speed, simply
release the accelerator pedal until the programmed cruise speed is reached again.

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.

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
The change from one level of alertto the next takes place if the drivingconditions do not change (speedunchanged, no change of lane...)
Severe weather conditions (very heavy rain, accumulation of snow in front of the radar) may interfere with the operation of the system, resulting inthe display of the message " Systeminactive: Reduced visibility
". T hesystem remains unavailable until themessage disappears.
If the speed of your vehicle is too high when approaching another vehicle, the first level of aler t may not be displayed: the level 2 aler t may be displayeddirectly.
On the other hand, the level 1 aler t is never displayed with the triggeringthreshold 3 (close).
Alerts
According to the collision risk detected by thesystem and the aler t threshold chosen, three
levels of aler t can be triggered:
Level 1: visual aler t only (orange)indicating that the vehicle in front is
very close. The message " Vehicle close" is displayed.
Level 2 : visual (red) and audible alerts indicating that a collision is imminent. The message "Brake!
" is
displayed. Thi
s level of alert is based on the inter-vehicletime between your vehicle and the one in front.
Thi
s level of alert is based on a time beforecollision. It takes account of the vehicle
dynamics, the speed of your vehicle and
the speed of the vehicle in front, the driving
conditions, the situation with your vehicle (cornering, pedals pressed, etc.) to trigger the
alert at the right moment. Level
3: an increase in
the tension of the driver'sseat belt, to hold the driver
against the backrest of their seat.
The 3rdlevel of aler t is not triggered or is interrupted in the event of an impactbetween the two vehicles. The increase in the tension of the driver's seat belt is not intended as analer t for the driver: it does not in anycircumstances assure the function of driver safety.The triggering of this aler t does not act on the safety functions provided by theseat belts.

Driving
Park Assist
This system provides active assistance with parking, detecting a parking space then controlling the steering to park in the space. It controls the steering while the driver manages the accelerator, brakes, gears andclutch (manual gearbox). During phases of entry into and exit from a parking space, the system provides visual and audible information
to the driver in order to make the manoeuvres safe. It may be necessary to move for wards and backwards more than once.
During a manoeuvre the steering wheelturns quickly: do not hold the steeringwheel, do not place your hand between
the spokes of the steering wheel and take care with loose and bulky clothing, scarves, handbags... There is a risk of injury.
When Park Assist is activated, itprevents a change to STOP mode of Stop & Start. In STOP mode, activation of Park Assist restarts the engine.
The Park Assist system cannot in anycircumstances replace the care and responsibility of the driver.
The driver must remain in control of their vehicle ensuring that thespace remains clear throughout themanoeuvre. In some circumstances, the sensors may not detect small obstacles located in their blind spots.
The driver can take control at any time bygripping the steering wheel.
The Park Assist s
ystem provides assistance for
the following manoeuvres:
- entr
y into a parallel parking space
- exitin
g from a parallel parking space
- ba
y parking
The Park Assist system takes control of the power steering for a maximumof 4 manoeuvre cycles. The functionis deactivated after these 4 cycles.If you think that your vehicle is notpositioned correctly, you should then take control of the steering to carry outthe manoeuvre.
The Park Assist system cannot workwith the engine off.

Safety
Electronic Stability Programme (ESC: Electronic Stability Control) incorporating the
following systems:
- the anti-lock braking system (ABS) and the electronic brake force distribution (EBFD),
- the emergency braking assistance,
- the anti-slip regulation (ASR) or tractioncontrol,
- the dynamic stability control (DSC).
Electronic stability programme (ESC)
Definitions
Anti-lock braking system (ABS)and electronic brake force
distribution
(EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and provides improved control in corners, in par ticular on poor or slippery road surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to reach the optimum braking pressure more quickly and therefore reduce the stopping
distance.
It is triggered according to the speed at which
the brake pedal is pressed. This is felt by a reduction in the resistance of the pedal and an increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control) optimises traction in order to avoid
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle onacceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed by the vehicle and that required bythe driver, the DSC monitors each wheel and
automaticall
y acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.

Safety
Intelligent traction control
s
ystem ("Snow motion")
When this warning lamp comes on,coupled with the STOPwarning lamp,
accompanied by an audible signal and a
message, it indicates that there is a fault
with the electronic brake force distribution(EBFD), which could cause loss of control of the vehicle when braking.
Operation
When this warning lamp comes on,
accompanied by an audible signaland a message, it indicates that there
is a fault with the ABS, which could cause loss of control of the vehicle
when braking.
Your vehicle has a system to help driving onsnow: intelligent traction control.This system detects situations of difficult surface adhesion that could make it difficult to move off or make progress on deep fresh snow
or compacted snow.
In these situations
, the intelligent traction control limits the amount of wheel slip to provide the best traction and trajectory controlfor your vehicle.
In extremely severe conditions (deep snow,mud, ...), when it proves impossible to move off,
it may be useful to temporarily deactivate theESP/ASR systems to allow the wheels to spin
freely and so allow movement of the vehicle.
The use o
f snow tyres is strongly recommended on sur faces offering low levels of adhesion.
Anti-lock braking system (ABS)
and electronic brake force
distribution
(EBFD)
When changing wheels (tyres and rims),make sure that these are approved for your vehicle.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal.
In emergency braking, press very firmly without releasing the pressure.
You must stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a qualified workshop.
