Safety
Airbags


System designed to maximise the safety of the
occupants (with the exception of the rear centre
passenger) in the event of violent collisions.
It supplements the action of the force-limiting
seat belts (with the exception of the rear centre
passenger).
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 airbags
are deployed instantly and protect the
occupants of the vehicle (with the exception
of the rear centre passenger); immediately
after the impact, the airbags deflate rapidly
so that they do not hinder visibility or the
exit of the occupants,

- in the case of a minor or rear impact or in
cer 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 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.
Deployment of the airbag(s) is
accompanied by a slight emission
of harmless smoke and a noise, due
to the activation of the pyrotechnic
car tridge incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience slight
irritation.
The noise of the detonation may result in
a slight loss of hearing for a short time.

Front airbags

System which protects the driver and front
passenger 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 steering wheel, driver's side, and the
dashboard, passenger's side to cushion their
for ward movement.

Safety

Deactivation

Only the passenger's front airbag can be
deactivated:


)
with the ignition off
, inser t the key in the
passenger airbag deactivation switch,

)
turn it to the "OFF"
position,

)
then, remove the key keeping the switch in
the new position.
According to version, this warning
lamp comes on in the instrument
panel and/or in the seat belt and
passenger's front airbag warning lamps display
when the ignition is on and until the airbag is
reactivated. To assure the safety of your child,
the passenger's front airbag must
be deactivated when you install a
"rear facing" child seat on the front
passenger seat.
Other wise, the child would risk being
seriously 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 ignition on, this warning
lamp comes on in the seat belt and
passenger's front airbag warning
lamps display for approximately one
minute, 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 not
install 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 the
instrument panel, accompanied by
an audible warning 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.

Lateral airbags

System which protects the driver and front
passenger 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 airbag is fitted in the seat backrest
frame, door side.

Deployment
Impact detection zones



A.
Front impact zone.

B.
Side impact zone.

The lateral airbags 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.

Safety






Curtain airbags

System which protects 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 cur tain airbag is built into the pillars and
the upper passenger compar tment 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.
If this warning lamp comes on in the
instrument 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
part of the wheel.
Passengers must not place their feet on the
dashboard.
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 can
contact a CITROËN dealer (see "Practical
information - § 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 is
deployed.
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 the
cur tain 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 occupants
and 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 been
stolen or broken into, have the airbag
systems checked.
All work on the airbag system must be carried
out 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 same
time discharging the hot gas via openings
provided for this purpose.
