Safety
Seat belts


Front seat belts


The front seat belts are fitted with a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side impact.
Depending on the severity of the impact, the
pretensioning 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 fastened
correctly by pulling the strap.



Unfastening



)
Press the red button on the buckle.

)
Guide the seat belt as it reels in.



Seat belt not fastened/

this warning lamp flashes for two minutes
accompanied by an audible signal of increasing
volume. Once these two minutes have elapsed,
this warning lamp remains on until the driver
and/or the front passenger fastens their
seat belt.

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.

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
