Seat belts


Front seat belts


The front seat belts are fitted with apretensioning and force limiting system.
This system improves safety in the frontseats in the event of a front or side impact.
Dependin
g on the severity of the impact, thepretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the seat belt on the chest of the occupant, so improving their protection.

Fastening
)Pull the strap, then inser t the tongue in the buckle.)Check that the seat belt is fastenedcorrectly by pulling the strap.



Unfastening
)Press the red button on the buckle.)Guide the seat belt as it reels in.

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.

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
