Airbags


System designed to maximise the safety of the
occupants (with the exception of the rear centrepassenger) in the event of violent collisions.
It supplements the action of the force-limiting
seat belts (with the exception of the rear centrepassenger).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts sustained in the impact detection zones:


- in the case of a serious impact, the airbagsare deployed instantly and protect the
occupants of the vehicle (with the exception
of the rear centre passenger); immediatelyafter the impact, the airbags deflate rapidlyso that they do not hinder visibility or theexit of the occupants,

- in the case of a minor or rear impact or incer tain roll-over conditions, the airbags
will not be deployed; the seat belt alone is sufficient to provide optimum protection in
these situations.
The airbags do not operate when theignition is switched off.This equipment will only deploy once. If a second impact occurs (during the same or a subsequent accident), theairbag will not be deployed again.


Impact detection zones
A.Front impact zone.
B. Side impact zone.

Deployment of the airbag(s) isaccompanied by a slight emissionof harmless smoke and a noise, dueto the activation of the pyrotechnic cartridge incorporated in the system.
This smoke is not harmful, but sensitive individuals may experience slightirritation.
The noise of the detonation may result ina slight loss of hearing for a shor t time.

Front airbags
System which protects the driver and frontpassenger in the event of a serious front impact
in order to limit the risk of injury to the head and
thorax.
The driver's airbag is fitted in the centre of the steering wheel; the front passenger's airbag is fitted in the dashboard above the glove box.

Deployment

The airbags are deployed simultaneously,unless the passenger's front airbag is
deactivated, in the event of a serious front
impact to all or par t of the front impact zone A ,
in the longitudinal centreline of the vehicle on a
horizontal plane and directed from the front to
the rear of the vehicle.
The front airbag inflates between the thorax
and head of the front occupant of the vehicle
and the steerin
g wheel, driver's side, and the
dashboard, passenger's side to cushion their
forward movement.

Safety

Deactivation
Only the passenger's front airbag can be deactivated:)inser t the key in the passenger airbagdeactivation switch,)turn it to the "OFF"position, )then, remove the key keeping the switch in
the new position.

According to version, this warninglamp comes on in the instrumentpanel and/or in the seat belt and passenger's front airbag warning lamps displaywhen the ignition is on and until the airbag is
reactivated.
To assure the safety of your child,the passenger's front airbag mustbe deactivated when you install a "rear facing" child seat on the front passenger seat. Other wise, the child would risk beingseriously injured or killed if the airbag were deployed.
Reactivation
When you remove the child seat, turn the switch to the "ON"position to reactivate the airbag and so assure the safety of your front passenger in the event of an impact.
With the i
gnition on, this warninglamp comes on in the seat belt andpassenger's front airbag warning lamps display for approximately oneminute, if the passenger's front airbag
is activated.


Operating fault

If this warning lamp flashes in the
instrument panel and/or in the seat belt and
passenger's front airbag warning lamps
display, contact a CITROËN dealer or a qualified
workshop. The passenger's front airbag may no longer
be deployed in the event of a serious impact.
If even one of the two airbag warning lamps comes on continuously, do notinstall a child seat on the front passenger seat.
Have the system checked by a CITROËN dealer or a qualified workshop.


If this warning lamp comes on in theinstrument panel, accompanied by an
audible warning and the display of amessage, contact a CITROËN dealer or a qualified
workshop to have the system checked. The airbags mayno longer be deployed in the event of a serious impact.

Lateral airbags
System which protects the driver and frontpassenger in the event of a serious side impact
in order to limit the risk of injury to the chest,
between the hip and the shoulder.
Each lateral airba
g is fitted in the seat backrest frame, door side.

Deployment
Impact detection zones
A.Front impact zone.
B.Side impact zone. The lateral airba
gs are deployed unilaterally in
the event of a serious side impact applied to all
or par t of the side impact zone
B , perpendicular
to the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The lateral airbag inflates between the hip and
shoulder of the front occupant of the vehicle
and the corresponding door trim panel.

187
Safety
Curtain airbags
System which protects the driver andpassengers (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 theside of the head.
Each curtain airbag is built into the pillars andthe upper passenger compartment area.

Deployment

The cur tain airbag is deployed at the same
time as the corresponding lateral airbag in the event of a serious side impact applied to all or par t of the side impact zone B, perpendicular
to the longitudinal centreline of the vehicle on a horizontal plane and directed from the outside
towards the inside of the vehicle.
The cur tain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Operating fault
In the event of a minor impact or bump on the side of the vehicle or if the vehicle rolls over, the airbag may not be deployed.
In the event of a rear or front collision, the airbag is not deployed.
I
f this warning lamp comes on in theinstrument panel, accompanied by
an audible signal and a message in
the screen, 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.

For the airbags to be fully effective, observe the following safety rules:
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre par t of the wheel.
Passengers must not place their feet on thedashboard.
If possible, 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.



Lateral airbags

Use only approved covers on the seats,compatible with the deployment the lateral airbags. For information on the range of seat covers suitable for your vehicle, you cancontact a CITROËN dealer (see "Practicalinformation - § Accessories").
Do not fix or attach anything to the seat backs (clothing...). This could cause injury to the chest or arms if the lateral airbag isdeployed.
Do not sit with the upper par t of the body any nearer to the door than necessary.


Curtain airbags

Do not fix or attach anything to the roof. This could cause injury to the head if thecurtain airbag is deployed.
If fitted on your vehicle, do not remove the grab handles installed on the roof, they play a par t in securing the cur tain airbags.


Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupantsand the airbags (a child, pet, object...). This could hamper the operation of the airbags or injure the occupants. After an accident or if the vehicle has beenstolen or broken into, have the airbagsystems checked. All work on the airbag system must be carriedout by a CITROËN dealer or a qualified workshop.
Even if all of the precautions mentioned are obser ved, a risk of injury or of minor burns to the head, chest or arms when an airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few milliseconds) then deflates within the sametime discharging the hot gas via openings provided for this purpose.
