Lighting and visibility
4To avoid damaging the wiper blades, do not operate the screenwash if the
screenwash reservoir is empty.
Only operate the screenwash if there is no
risk of the fluid freezing on the windscreen
and hindering visibility. During the winter
period, use "very cold climate" rated products.
Never top up with water.
Front intermittent wiping
In Intermittent mode, the driver can adjust the
wiping frequency by turning the ring to one of the
5 available positions.


The first (upper) position corresponds to the
longest time interval between 2 wipes for light
rain.
The last (lower) position corresponds to the
shortest time interval between 2 wipes
for heavy
rain.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off for more than 1 minute with the wiper
control stalk in the INT, 1 or 2 position, when
the ignition is switched on again:
–

the system works as soon as the vehicle
exceeds 6 mph (10 km/h), if the outside
temperature is below +3°C.
–


the system works immediately
, if the
outside temperature is above +3°C.
Automatic windscreen wipers
In AUTO mode, the front wipers work
automatically and adapt to the intensity of
precipitation depending on the sensitivity of the
sensor selected.
The rainfall detection function uses a rain/
sunshine sensor located at the top centre of the
windscreen, behind the rear view mirror.
In certain weather conditions (e.g. fog,
frost, snow , projections on salty roads),
the driver may have to return to manual
wiping.
Switching on/off
To switch on:
► Put the wiper control stalk in the AUT
O
position.
►

T
urn the ring to adjust the sensitivity of the
sensor.
A wiping cycle, accompanied by the display of
a message, confirms that the request has been
taken into account.
►

T
o switch off, put the wiper control stalk in
another position or in the 0 position.
Adjusting the sensitivity

The first position (upper) corresponds to the
lowest sensitivity of the sensor.
The last position (lower) corresponds to the
highest sensitivity of the sensor.
The higher the sensitivity, the faster the system
reacts and increases the wiping frequency.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off
for more than 1 minute with the wiper
control stalk in the AUTO position, when the
ignition is switched on again:
–

the system works, depending on the
volume of rain detected, as soon as the
vehicle exceeds 6 mph (10 km/h), if the
outside temperature is below +3°C.
–


the system works immediately
, depending
on the volume of rain detected, if the outside
temperature is above +3°C.

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).
–


Post Collision Safety Brake (PCSB).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
Anti-lock braking system (ABS)/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.
Electronic brake force distribution (EBFD)
manages overall braking pressure on each
individual wheel.
►

When braking in an emergency
, depress
the pedal very firmly and maintain this
pressure.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
The fixed illumination of this warning lamp signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Have it checked by a CITROËN dealer or a
qualified workshop.
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 the vehicle.
Stop as soon as it is safe to do so and switch off
the ignition.
Contact a CITROËN dealer or a qualified
workshop.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact
Have it checked by a CITROËN dealer or
a qualified workshop.
Post Collision Safety Brake
(PCSB)
If an accident is detected, the vehicle initiates
automatic post collision braking. The goal of this
system is to reduce the risk of further collisions if
the driver does not react.
The system is not operational if the capability
of the vehicle is to trigger and execute the

70
Safety
automatic post collision braking is not available,
as it can occur in destructive accidents or in
other specific accident scenarios.
It is possible to override the automatic braking by
pressing the brake pedal or accelerator pedal.
Operating conditions
The system operates, if the following conditions
are met:
–
Airbags or pyrotechnic seat belt pretensioners
have been deployed by the collision.
–


Braking systems and electric functions remain
continuously operational during and after
collision.
–


Driver has not depressed the brake or
accelerator pedal.
Malfunction
In the event of a
malfunction, one of these
warning lamps will come on fixed on the
instrument panel, accompanied by the Service
warning lamp, the display of a message and an
audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
This system reduces the emergency stopping
distance, by optimising the braking pressure. It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this
is 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 (or traction control) optimises
traction by using engine braking and by applying
the brakes on the driving wheels to avoid one
or more wheels spinning. It also enhances the
vehicle's directional stability.
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.
These systems are activated in the event of a problem with grip or trajectory
(confirmed by this warning lamp flashing on the
instrument panel).
Deactivation/Reactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system as soon as the level of
grip permits.
This function is set via theDriving/Vehicle touch screen menu.
Deactivation is confirmed by the lighting
of this indicator lamp on the instrument
panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched off, or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp comes on on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels

71
Safety
5(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by CITROËN
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings, refer to the
corresponding section.
Seat belts
Inertia reel
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to the shape of the user. The seat
belt returns to its storage automatically when it
is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiting system
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Front seat belts
The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting
system.
Rear seat belts

Each of the rear seats has a three-point seat belt
with inertia reel.
The outer seats are fitted with a pyrotechnic
pretensioning and force limiting system.
Fastening
► Pull the strap, then insert the tongue into the
buckle.
►

Check that the seat belt is fastened correctly
by pulling on the strap.
Unfastening
► Press the red button on the buckle.
► Guide the seat belt as it is reeled in.

73
Safety
5To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodies present (e.g. a coin) before fastening.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible over the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
In order to be effective, a seat belt must:
–

be tightened as close to the body as
possible.
–


be pulled in front of you with a smooth
movement, ensuring that it is not twisted.
–


only be used to secure one person.
–


not show signs of tearing or fraying.
–


not be changed or modified, in order to
avoid affecting its performance.
Recommendations for children
Use a suitable child seat if the passenger
is less than 12 years old or shorter than 1.5
metres.
Never use the same seat belt to secure more
than one child.
Never carry a child on your lap.
For more information on Child seats, refer to
the corresponding section.
Maintenance
In accordance with current safety
regulations, for all work on your vehicle's
seat belts, contact a qualified workshop with
the skills and equipment needed, which a
CITROËN dealer is able to provide.
Have the seat belts checked regularly by a
CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by CITROËN
dealers.
Airbags
General information
System designed to help improve the safety
of the occupants sitting in the front seats and
the rear outer seats, in the event of a violent
collision. The airbags supplement the action
of the seat belts equipped with a force limiting
system.
Electronic detectors record and analyse the
front and side impacts sustained in the impact
detection zones:
–

In the event of violent impact, the airbags
deploy instantly and help better protect the
occupants of the vehicle; immediately after the
impact, the airbags deflate rapidly in order not
to hinder the visibility or the possible exit of the
occupants.
–

In the event of a slight impact, a rear impact
and under certain rollover conditions, the airbags
may not deploy; only the seat belt helps to
protect you in these situations.
The seriousness of the impact depends on the
nature of the obstacle and the speed of the
vehicle at the moment of collision.
The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once. If a
second impact occurs (during the same or a
subsequent accident), the airbag will not be
deployed again.
Impact detection zones
A. Front impact zone
B. Side impact zone
When one or more airbags are deployed,
the detonation of the pyrotechnic charge

74
Safety
incorporated in the system makes a noise and
releases a small quantity of smoke.
This smoke is not harmful, but sensitive
individuals may experience irritation.
The detonation noise associated with the
deployment of one or more airbags may result
in a slight loss of hearing for a short time.
Front airbags

System that protects the driver and front
passenger in the event of a serious front impact,
limiting the risk of head and chest injury.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger airbag is
fitted in the dashboard above the glove box.
* For more information on Deactivating the front passenger airbag, refer t\
o the corresponding section.
Deployment
They deploy, except the front passenger airbag
if it is deactivated*, in the event of a serious front
impact to all or part of the front impact zone A.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the
steering wheel, driver's side, and the dashboard,
passenger's side, to cushion their forward
movement.
Lateral airbags

In the event of a serious side impact, this system
protects the driver and front passenger to
mitigate the risk of injury to the chest, between
the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, on the door side.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all
or part of the side impact zone B.
The lateral airbag inflates between the chest of
the vehicle's occupant and the corresponding
door panel.
Curtain airbags
System contributing towards greater protection
for the driver and passengers (with the exception
of the rear centre passenger) in the event of a
serious side impact in order to limit the risk of
injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
Deployment
It deploys simultaneously with the corresponding
lateral airbag in the event of a serious side
impact applied to all or part of the side impact
zone B.
The curtain airbag inflates between the front
and rear occupants of the vehicle and the
corresponding windows.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel.
