AIR BAGS
System designed to maximise the
safety of the occupants (with the
exception of the rear centre pas-
senger) in the event of violent col-
lisions. It supplements the action of
the force-limiting seat belts.
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 air bags are triggered instant-
ly and protect the occupants of
the vehicle (with the exception of
the rear centre passenger); im-
mediately after the impact, the
air bags deﬂ ate rapidly so that
they do not hinder visibility or the
exit of the occupants,
- in the case of a minor or rear im- pact or in certain roll-over con-
ditions, the air bags will not be
triggered; the seat belt alone is
sufﬁ cient to provide optimum
protection in these situations.
The air bags do not operate when
the ignition is switched off.
This equipment will only operate
once. If a second impact occurs
(during the same or a subsequent
accident), the air bag will not operate. Impact detection zones

A. Front impact zone.

B. Side impact zone.
Triggering of the air bag(s) is ac-
companied by a slight emission of
harmless smoke and a noise, due
to the activation of the pyrotechnic
cartridge incorporated in the system.
This smoke is not harmful, but sen-
sitive 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 head and
chest of the driver and front passen-
ger in the event of a front impact.
The driver's airbag is incorporated in
the centre of the steering wheel; the
front passenger's airbag is incorpo-
rated in the fascia above the glove
box.
Operation
The airbags are triggered simultane-
ously, unless the passenger's front
airbag is deactivated, in the event of
a serious front impact to all or part of
the front impact zone
A , in the lon-
gitudinal centreline of the vehicle on
a horizontal plane and directed from
the front to the rear of the vehicle.
The front airbag inﬂ ates between
the front occupant of the vehicle and
the fascia to cushion their forward
movement.

Deactivation
This warning lamp comes on
in the instrument panel when
the ignition is on and until the
airbag is reactivated.
To guarantee the safety of your
child, it is imperative that the pas-
senger airbag is deactivated when
you install a "rearwards-facing" child
seat on the front passenger seat.
Otherwise, the child would risk be-
ing seriously injured or killed if the
airbag were triggered. Reactivation
When you remove the child seat,
turn switch
1 to the "ON" position to
reactivate the airbag and so guaran-
tee the safety of your front passen-
ger in the event of an impact.
Operating fault

If this warning lamp comes
on in the instrument panel,
accompanied by an audible
warning and a message on
the multifunction screen, contact a
CITROËN dealer to have the sys-
tem checked. The airbags may no
longer be triggered in the event of a
serious impact.
If this warning lamp ﬂ ashes,
contact a CITROËN dealer.
If both airbag warning lamps come
on continuously, do not install a
"rearwards-facing" child seat on
the front passenger seat.
Have it checked by a CITROËN
dealer.
Only the front passenger's airbag
can be deactivated:

 with the ignition off , insert the
key in the passenger airbag de-
activation switch 1 ,

 turn it to the "OFF" position,

 then, remove the key keeping
the switch in this position.
