Advice
The driver must ensure that passengers use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not interchange the seat belt buckles, as
they will not fulfil their role fully.
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 on 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;– must be pulled in front of you with a smooth movement, ensuring that it is not twisted;– must only be used to secure one person;– must not show signs of tearing or fraying;– must not be changed or modified, in order to avoid affecting its performance.
Recommendations for childrenUse a suitable child seat if the passenger
is less than 12 years old or shorter than one
and a half 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 repairs on your vehicle's
seat belts, go to 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.

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
incorporated in the system makes a noise and
releases a small quantity of smoke.
This smoke is not harmful, but sensitive
individuals may experience slight 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.

Safety
Front airbags

This system protects the driver and front
passenger in the event of a serious front impact,
in order to limit the risk of head and chest
injuries.
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.
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.
* For more information on Deactivating the front passenger airbag, refer to the corresponding section.
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, 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 hip and
shoulder 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
If this warning lamp comes on in the instrument panel, you must contact a
CITROËN dealer or a qualified workshop to have
the system checked.
The airbags may no longer be deployed in the
event of a serious impact.
In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly around
the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must only
be performed by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms cannot be
ruled out when an airbag is deployed. The
airbag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.

Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (clothes, etc.), as this could cause
injuries to the thorax or arm when the lateral
airbag is deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
Such work must only be done by a CITROËN
dealer or a qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof, as they play a part in securing the
curtain airbags.
Child seats
The regulations on carrying children are specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
– In accordance with European regulations, all
children under the age of 12 or less than 4
ft 11” (150 cm) tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.
– Statistically, the safest seats in your
vehicle for carrying children are the rear
seats.
– Children weighing less than 9 kg must
travel in the "rear facing" position, whether in
the front or rear of the vehicle.
