Emergency or assistance
call
In an emergency, press this
button for more than 2 seconds.
The flashing green LED and
the voice message confirm that
the call has been made to the
"Localised Emergency Call"
service*.
Pressing this button again cancels the
command and the green LED goes off.
The green LED remains on (without flashing)
when communication is established.
It goes off at the end of the call.
"Localised Emergency Call" immediately
locates your vehicle and contacts you in
your own language**, and – if necessary –
requests that relevant emergency ser vices be
dispatched**. In countries where the ser vice is
not available, or when the locating ser vice has
been expressly declined, the call is sent directly
to the emergency services (112) without the
vehicle location.
If an impact is detected by the airbag
control unit, an emergency call is made
automatically and independently of
possible deployment of any airbags.

Advice
The driver must ensure that passengers use
the seat belts correctly and that they are all
fastened before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do not interchange the seat belt buckles as
they will not fulfil their role fully.
The seat belts are fitted with an inertia reel
permitting automatic adjustment of the
length of the strap to your size. The seat belt
is stowed automatically when not in use.
Before and after use, ensure that the seat
belt is reeled in correctly.
The lower part of the strap must be
positioned as low as possible on the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
The inertia reels have an automatic locking
device at the time of a collision, during
sudden braking or if the vehicle turns over.
You can release the device by pulling the
strap firmly and then releasing it so that it
reels in slightly.In order to be effective, a seat belt must:
-
b e tightened as close to the body as
possible,
-

b
e pulled in front of you with a smooth
movement, checking that it does not twist,
-

b
e used to restrain only one person,
-

n
ot show any signs of cuts or fraying,
-

n
ot be converted or modified to avoid
affecting its performance.
In accordance with current safety regulations,
for all repairs on your vehicle's seat belts, go
to a qualified workshop with the skills and
equipment needed, which a CITROËN dealer
is able to provide.
Have your seat belts checked regularly by
a CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by CITROËN
dealers.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly. Recommendations for children
Use a suitable child seat if the passenger is
less than 12 years old or shorter than one and
a half metres.
Never use the same seat belt to secure more
than one person.
Never allow a child to travel on your lap.
For more information on Child seats
, refer to
the corresponding section.
In the event of an impact
Depending on the nature and seriousness
of the impact , the pyrotechnic pretensioner
device may be deployed before and
independently of the airbags. Deployment
of the pretensioners is accompanied by a
slight discharge of harmless smoke and a
noise, due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and, if necessary, replaced,
by a CITROËN dealer or a qualified
workshop.

Airbags
General information
System designed to contribute towards
improving passenger safety (with the exception
of the rear centre passenger) in the event of
violent collisions. The airbags supplement the
action of the seat belts fitted with force limiters
(all except 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:
-
i
n the case of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of 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,
-

i
n the case of a minor or rear impact or
in certain rollover conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
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. The deployment of an airbag is
accompanied by a slight emission of
smoke and a noise, due to the detonation
of the pyrotechnic charge incorporated in
the system.
This smoke is not harmful, but sensitive
individuals may experience slight irritation.
The detonation noise associated with the
deployment of an airbag 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 airbag is
fitted in the dashboard above the glove box.
Safety

82
The front passenger airbag must be
deactivated. Otherwise, the child risks
being seriously injured or killed if the
airbag is deployed.
"Forward facing"
When a "for ward facing" child seat is installed
on the front passenger seat , adjust the
vehicle's seat to the intermediate longitudinal
position with the backrest straightened and
leave the front passenger airbag activated.
Ensure that the seat belt is correctly
tensioned.
For child seats with a support leg, ensure
that the latter is in firm contact with the
floor. If necessary, adjust the passenger
seat. Passenger seat adjusted to the intermediate
longitudinal position.
Deactivating the front
passenger airbag
Never install a "rear ward facing" child
restraint system on a seat protected by an
active front airbag.
This could cause the death of the child or
serious injury.The warning label present on both sides of the
passenger sun visor repeats this advice.
In line with current legislation, this warning is
available in all of the languages required on the
following pages.
Passenger airbag OFF
This label is located on the middle door pillar,
passenger side.
For more information on the Airbags ,
refer to the corresponding section.
Safety

83
Deactivating the front
passenger airbag
Only the front passenger airbag can be
deactivated.
F
W
ith the ignition off , insert the key into the
passenger airbag deactivation switch.
F

T
urn it to the OFF position.
F

R
emove the key, leaving the switch in this
position.
When the ignition is switched on,
this warning lamp comes on in the
seat belts and front passenger
airbag warning lamps display or in
the instrument panel. It stays on
while the airbag is deactivated. To ensure the safety of your child, the front
passenger airbag must be deactivated
when you install a "rear ward facing" child
seat on the front passenger seat.
Otherwise, the child could risk being
seriously injured or killed if the airbag
were deployed.
Reactivating the front
passenger airbag
Once you have removed a "
rearward facing"
child seat, with the ignition off , turn the switch
to the ON position to reactivate the airbag and
so ensure the safety of a front passenger in the
event of an accident.
When the ignition is switched on,
this warning lamp comes on in the
seat belts and front passenger
airbag warning lamps display
or in the instrument panel for
approximately one minute to signal
that the front airbag is activated.
