5Electronic 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,
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.

Driving on flooded roads
Before entering into a flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving
recommendations, particularly on flooded
roads, refer to the corresponding section.
Operation
Main conditions for operation
– The driver ’s door must be closed.– The driver's seat belt must be fastened.– The state of charge of the battery must be sufficient.– The temperature of the engine must be within its nominal operating range.– The outside temperature must be between 0°C and 35°C.
Putting the engine into standby
(STOP mode)
The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop.
– With a manual gearbox: with the gear lever in
neutral and the clutch pedal released.
– With an automatic gearbox: with the gear
selector in position D or M, the brake pedal
depressed until the vehicle stops or the gear
selector in position N, with the vehicle stationary.
Time counter
A time counter adds up the time spent in standby
during the journey. It is reset to zero every time
the ignition is switched on.
Special cases:
The engine will not go into standby if all of the
conditions for operation are not met and in the
following cases.
– Steep slope (ascending or descending).– Vehicle has not exceeded 6 mph (10 km/h) since the last engine start (with the key or the
“START/STOP” button).
– Needed to maintain a comfortable temperature in the passenger compartment.– Demisting active.– Braking assistance being used.In these cases, this indicator lamp flashes for a few seconds, then goes off.
After the engine has restarted, STOP
mode is not available until the vehicle
has reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
Engine restarting (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
► With a manual gearbox : with the clutch
pedal fully depressed.
► With an automatic gearbox :• With the selector in position D or M: with the
brake pedal released.
• With the selector in position N and the brake
pedal released: with the selector at D or M.

pedal depressed: with the selector at R, N,
D or M.
• Reverse gear engaged.
Special cases
The engine will restart automatically if all
conditions for operation are met again and in the
following cases.
– Vehicle speed exceeds 2 mph (3 km/h).– Some specific conditions (braking assistance, air conditioning setting, etc.).In these cases, this indicator lamp flashes for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, the button’s
indicator lamp flashes briefly, then remains on.
Have the vehicle checked by a CITROËN dealer
or a qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
► Switch off the ignition then start the engine again with the key or the " START/STOP" button.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a CITROËN dealer or a
qualified workshop.

98
Driving
► In the event of a puncture, use the temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
The reinitialisation of the system is done with the
ignition on and the vehicle stationary:
– Via the vehicle configuration menu for vehicles fitted with a touch screen.– Via the button on the dashboard for vehicles without a touch screen.

In this case, under-inflation monitoring of the
tyres is no longer assured.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the 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)

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.

101
Driving
6In certain extreme weather conditions
(rain and/or snow, bright sunshine, etc.)
the head-up display may not be legible or
may suffer temporary interference.
Some sunglasses may hamper reading of the
information.
To clean the blade, use a clean, soft cloth
(such as a spectacles cloth or microfibre
cloth). Do not use a dry or abrasive cloth
or detergent or solvent products as these
could scratch the blade or damage the anti-
reflection coating.
This system operates when the engine is running, and the settings are saved when
the ignition is switched off.
Memorising speeds
This function allows speeds to be saved, which
can then be offered to set the two systems: the
speed limiter (to limit the speed of the vehicle) or
the cruise control (for a vehicle cruising speed).
You can memorise up to six speed settings for
each of the two systems.
By default, some speed settings are already
memorised.
As a safety measure, the driver must only modify the speed settings when
stationary.
Memorising speeds

This function can be accessed in the Driving / Vehicle menu of the touch
screen.
► Select the "Driving functions " tab.► Select the "Adjusting Speeds " function.

► Select the "Speed limiter" or "Cruise
control" tab corresponding to the equipment you
want to memorise new speed settings for.
► Select the speed setting you want to change.► Enter the new value using the numeric keyboard and confirm.
► By default, some speed settings are already memorised.
“MEM” button

With this button, you can select a memorised
speed setting to use with the speed limiter or the
programmable cruise control.
For more information on the Speed limiter or
Cruise control, refer to the associated section.
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .

102
Driving
This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
– Speed limit signs detected by the camera.– Speed limit details from the navigation system mapping.
Navigation mapping should be regularly
updated in order to receive accurate
speed limit information from the system.
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account so that you
observe the speed limit.
For the system to work correctly when
changing country, the speed unit in the
instrument panel must correspond to that of
the country you are driving in.
The automatic reading of road signs is a driving aid system and does not always
display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
Specific speed limits, such as those for
heavy goods vehicles, are not displayed.
The display of the speed limit in the
instrument panel is updated when passing
a speed limit sign intended for cars (light
vehicles).

exceed the programmed speed by pressing the
accelerator pedal.
The cruise control is temporarily overridden and
the programmed speed setting flashes.
To return to the speed setting, release the
accelerator pedal.
Once the vehicle has returned to the
programmed speed, the cruise control takes over
again: the display of the programmed speed
setting becomes steady again.
When descending a steep hill, the cruise
control system cannot prevent the
vehicle from exceeding the programmed
speed.
You may have to brake to control the speed of
your vehicle. In this case, the cruise control is
automatically paused. To activate the system again, with the speed
of the vehicle above 25 mph (40 km/h), press
button 4.
Switching off
► Turn the thumbwheel
1 to the "OFF" position:
the cruise control information disappears from
the screen.
Malfunction

system.
Have it checked by a CITROËN dealer or a
qualified workshop.
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


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.
