camera, located at the top of the windscreen.
Operating limits
The system may be disrupted or not work
correctly:
–

When visibility conditions are poor
(e.g.

snowfall, heavy rain).
–

If the windscreen is dirty
, misted-up or
masked (e.g.
sticker) in front of the camera.
–

If the vehicle is facing highly reflective signs
or safety barrier reflectors.
The system is not able to detect:
–


Road users that do not have their own
lighting, such as pedestrians.
–


V

ehicles with hidden lighting (e.g. travelling
behind a safety barrier on the motorway).
–

V

ehicles at the top or bottom of a steep
slope, on winding roads, on crossroads.
Maintenance
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal surface of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
obstruct the camera.

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

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.

Statistically
, the safest seats in your
vehicle for carrying children are the rear
seats.
–

Children weighing less than 9 kg must
travel in the "rearward facing" position,
whether in the front or rear of the vehicle.
It is recommended that children travel
on the rear seats of the vehicle:
–

‘rearward facing’ up to the age of 3,
–

‘forward facing’ over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
Advice
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
harness of child seats, keeping the slack
relative to the child's body to a minimum,
even for short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it secures
the child seat firmly on the seat of the vehicle.
If the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint before
installing a child seat with a backrest on a
passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint once
the child seat has been removed.
Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
Use a booster seat with backrest, equipped
with a belt guide at shoulder level.
Additional protections
To prevent accidental opening of the
doors and rear windows, use the "Child lock".
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of the
sun, fit side blinds on the rear windows.
As a safety precaution, do not leave:
– a child alone and unattended in a vehicle,
– a child or an animal in a vehicle which is
exposed to the sun, with the windows closed,
–

the keys within reach of children inside the
vehicle.
Child seat at the rear
Forward-facing or rearward-facing



► Move the vehicle's front seat forward and
straighten the backrest so that the legs of the
child in the forward-facing or rearward-facing
child seat itself do not touch the vehicle's front
seat.
►

Check that the backrest of the forward-facing
child seat is as close as possible to the backrest
of the vehicle's rear seat, and ideally in contact
with it.
Centre rear seat
A child seat with a support leg must never be
