This system:– warns the driver that their vehicle is at risk of collision with the vehicle in front or a pedestrian.– reduces the vehicle's speed to avoid a collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.– Active Safety Brake (automatic emergency braking).

The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for
vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start-up.
The system can be deactivated or activated via
the vehicle settings menu.
Deactivation of the system is signalled by the illumination of this indicator lamp,
accompanied by the display of a message.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"COLLISION ALT" (Automatic emergency
braking).
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Auto. emergency braking".
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Automatic
emergency braking".
Operating conditions and
limits
ESC system in working order.
ASR system activated.
Seat belts fastened for all passengers.
Stabilised speed on unwinding roads.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
– Towing a trailer.– Carrying long objects on roof bars.– Vehicles with snow chains fitted.– Before using an automatic car wash, with the engine running.– Before placing the vehicle on a rolling road in a workshop.– Towed vehicle, engine running.– When a "space-saver" type spare wheel is fitted (depending on version).– If the brake lamps are not working.– Following impact to the windscreen close to the detection camera.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.

Driving
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Fatigue
Detection System ".
Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65 km/h).This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
– With the engine running, the vehicle has been stationary for more than 15 minutes.– The ignition has been switched off for a few minutes.– The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).
Driver Attention Warning
Depending on version, the "Coffee Break Alert"
system is combined with the "Driver Attention
Warning" system.


Using a camera placed at the top of the windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow , mud) or multiple (roadworks);– close to the vehicle ahead (lane markings not detected);– roads that are narrow, winding, etc.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.


Deactivation / Activation
The system is activated every time the ignition
is switched on.


OFF

► To deactivate the system, press this button.Deactivation is signalled by the lighting
of the indicator lamp on the button and
this warning lamp on the instrument panel.
Reactivation is carried out via another press; the
indicator lamp on the button and the warning
lamp go out.
Detection
If an unexpected change of direction is detected, this warning lamp flashes in the
instrument panel accompanied by an audible
signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20

Driving
“Go forwards".
The manoeuvring status is indicated by these
symbols:
Manoeuvre in progress (green).
Manoeuvre cancelled or finished (red) (the arrows indicate that the driver must
resume control of the vehicle).
The maximum speeds during manoeuvres are
indicated by these symbols:
75 mph or 7 km/h, for parking space entry.
53 mph or 5 km/h, for parking space exit.
During manoeuvring phases, the steering
wheel performs rapid turns: do not hold
the steering wheel or put your hands between
the spokes of the steering wheel. Watch out
for any objects that could interfere with the
manoeuvre (loose clothing, scarf, tie, etc.).
Risk of injury!
It is the driver's responsibility to constantly
monitor the traffic, especially vehicles coming
towards you.
The driver should check that no objects or
people are obstructing the vehicle’s path.
The images from the camera(s) displayed on the touch screen may be
distorted by the terrain.
In shady areas, or in inadequate sunlight
or lighting conditions, the image may be
darkened and with lower contrast.
The manoeuvre can be permanently interrupted
at any time, either by the driver or automatically
by the system.
Interruption by the driver:
– taking over control of the steering.– activating the direction indicator lamps on the opposite side to that of the manoeuvre.– unfastening the driver's seat belt.– switching off the ignition.Interruption by the system:– vehicle exceeding the speed limit of 5 mph (7 km/h) during parking space entry manoeuvres, or 3 mph (5 km/h) during parking space exit manoeuvres.– activation of anti-slip regulation on a slippery road.
– opening of a door or the boot.– engine stall.– system malfunction.– after 10 manoeuvres to enter or exit a parallel parking space and after 7 manoeuvres to enter a
parking bay.
Interrupting the manoeuvre automatically
deactivates the function. The manoeuvre symbol is displayed in red,
accompanied by the "
Manoeuvre cancelled"
message on the touch screen.
A message prompts the driver to take back
control of the vehicle.
End of the parking space entry or exit
manoeuvre
The vehicle stops as soon as the manoeuvre is
completed.
The manoeuvre symbol is displayed in red,
accompanied by the message “ Manoeuvre
completed” on the touch screen.
When entering a parking space, the driver may
be required to complete the manoeuvre.
Operating limits
– The system may suggest an unsuitable parking space (No Parking area, work in
progress with damaged road surface, location
alongside a ditch, etc.).
– The system may indicate that a space has been found but not offer it because of a fixed
obstacle on the opposite side of the manoeuvre,
which would not allow the vehicle to follow the
necessary trajectory for parking.
– The system may indicate that a space has been found but not engage the manoeuvre
because the road is too narrow.
– The system is not designed to perform the parking manoeuvre on a sharp bend.– The system does not detect spaces that are much larger than the vehicle or are bounded by
obstacles that are very low (pavements, studs, etc.) or very thin (trees, posts, wire fences, etc.).– Certain obstacles located in the sensors’ blind spots may not be detected or may no longer be
detected during the manoeuvre.
– Certain materials (fabrics) absorb sound waves: pedestrians may not be detected.– A front or rear impact to the vehicle can upset the sensors’ settings, which is not always
detected by the system: distance measurements
may be distorted.
– If the boot is heavily loaded, the vehicle may tilt, affecting distance measurements.
The vehicle's sensors and camera(s) may be
impaired by:
– accumulated snow or fallen leaves on the road,– adverse weather conditions (heavy rain, thick fog, falling snow),– noise interference from noisy vehicles and machinery (lorries, pneumatic drills, etc.).
Do not use the function under the
following exterior conditions:
– Alongside a soft shoulder (e.g. ditch) or quay or on the edge of a drop.– When the road surface is slippery (e.g. ice).
If any of the following malfunctions
occurs, do not use the system:
– If a tyre is under-inflated.– If one of the bumpers is damaged.– If one of the cameras is faulty.

The battery (-) terminal is not accessible, use the
engine mounting.
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a battery booster.
Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery booster.
Check beforehand that the backup battery
has a nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact with
each other.
Switch off all the electrical consumers on both
vehicles (audio system, wipers, lighting, etc.).
Make sure that the jump leads are not close
to moving parts of the engine (fan, belts, etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if your vehicle has one.► Connect the red cable to the positive terminal (+) of flat battery A (at the metal elbow) then to
the positive terminal (+) of backup battery B or
the booster.
► Connect one end of the green or black cable to the negative terminal (-) of backup battery B
or the booster (or an earth point on the other
vehicle).
► Connect the other end of the green or black cable to earth point C on the broken down
vehicle.
► Start the engine of the vehicle with the good battery and leave it running for a few minutes.► Operate the starter on the broken down vehicle and let the engine run.
If the engine does not start straight away, switch
off the ignition and wait a few moments before
trying again.
► Wait until the engine returns to idle then disconnect the jump lead cables in the reverse
order.
