Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
– Anti-lock braking system (ABS) and Electronic brake force distribution (EBFD).– Emergency braking assistance (EBA).– Anti-slip regulation (ASR).– Dynamic stability control (DSC).
Anti-lock braking system
(ABS) and Electronic brake
force distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
This warning lamp, when lit together with the STOP and ABS warning lamps,

This warning lamp, when lit together with the STOP and ABS warning lamps,
accompanied by a message and an audible
signal, indicates an EBFD malfunction.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.
The normal operation of the ABS may result in slight vibrations in the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems checked by a CITROËN dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
In an emergency, this system enables you
to reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation 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 braking efficiency.
Anti-slip regulation (ASR) / Dynamic stability control
(DSC)
Anti-slip regulation optimises traction using
engine braking and by applying the brakes on
the driving wheels to avoid wheel spinning. It
also enhances the vehicle's directional stability
while accelerating.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
This warning lamp on the instrument panel flashes to indicate that they are
operating.
Deactivation / Reactivation
In exceptional conditions (starting a vehicle stuck
in mud, immobilised in snow, on soft ground,
etc.), it may be useful to deactivate the ASR
system to freely spin the wheels and regain
traction.
Reactivate the system as soon as the level of
grip permits.
It is set via the Driving / Vehicle touch
screen menu.

mirrors.


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
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.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
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.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away from the sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
– Ensure that the mat is secured correctly .– Never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
in the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Head-up display
System which projects various information onto a
smoked blade in the driver's field of vision so that
they do not have to take their eyes off the road.

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.
