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 equipped with an
inertia reel which allows the strap length
to automatically adjust to your shape.
The seat belt returns to its storage
automatically when it is not used.
The inertia reels are fitted with a device
which automatically locks the strap in the
event of a
collision, emergency braking or
if the vehicle rolls over. You can release
the device by pulling the strap firmly and
then releasing it so that it reels in slightly.
Before and after use, ensure that the seat
belt is reeled in correctly.
After folding or moving a
seat or rear
bench seat, ensure that the seat belt is
positioned and reeled in correctly. Installation
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.
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 in order
not to affect its per formance.
Recommendations for children
Use a
child seat appropriate to the child's
age, weight and size.
Never use the same seat belt to secure
more than one child.
Never allow a
child to travel on your lap.
For more information on Child seats , refer
to the corresponding section. Servicing
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.
In the event of an impact
Depending on the nature and seriousness
of the impacts, the pyrotechnic device
may trigger before and independently of
airbag deployment. 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.
Safety

103
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting
position.
Wear a
correctly adjusted seat belt.
Do not leave anything between the
occupants and the airbags (a child, pet,
object, etc.), nor fix or attach anything
close to or in the way of the airbag release
trajectory; this could cause injuries during
their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly
around the airbags.
After an accident or if the vehicle has
been stolen, have the airbag systems
checked.
All work on the airbag systems must only
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 cannot
be ruled out when an airbag is deployed.
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. 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.
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.
Do not fix or attach anything to the
steering wheel or dashboard, as this
could cause injuries when the airbags are
deployed.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed. Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the
lateral airbags. For information on the
range of seat covers suitable for your
vehicle, contact the CITROËN network.
Do not fix or attach anything to the seat
backrests (clothes, etc.), as this could
cause injuries to the thorax or arm when
the lateral airbag is deployed.
Do not sit with the upper part of the body
any nearer to the door than necessary.
The vehicle's front door panels include
side impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior
trim could compromise the operation of
these sensors – risk of malfunction of the
lateral airbags!
Such work must only be done by
a
CITROËN dealer or a qualified
workshop.

General points relating to
child seats
The legislation on carrying children is
specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please obser ve the
following recommendations:
-

I

n accordance with European regulations,
all children under the age of 12
or less
than one and a
half metres tall must
travel in approved child seats suited to
their weight , on seats fitted with a
seat belt
or ISOFIX mountings.
-

S
tatistically, the safest seats in your
vehicle for carr ying children are the rear
seats.
-

A c
hild weighing less than 9 kg must
travel in the " rearward facing " position
both in the front and in the rear.
It is recommended that children travel on
the rear seats of your vehicle:
-
"rearward facing " up to the age of 3,
-
"forward facing " over the age of 3. Ensure that the seat belt is positioned and
tightened correctly.
For child seats with a
support leg, ensure
that the support leg is in firm and steady
contact with the floor.
At the front: if necessary, adjust the
passenger seat.
At the rear: if necessary, adjust the
relevant front seat.
Remove and stow the head restraint
before installing a
child seat with backrest
on a


passenger seat. Refit the head
restraint once the child seat has been
removed.
Advice
An incorrectly installed child seat
compromises the child's safety in the
event of an accident.
Ensure that there is no seat belt or seat
belt buckle under the child seat, as this
could destabilise it.
Remember to fasten the seat belts or
the child seat harness keeping the slack
relative to the child's body to a
minimum,
even for short journeys.
When installing a


child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it
secures the child seat firmly on the seat
of your vehicle. If your passenger seat is
adjustable, move it forwards if necessary.
The head restraint must be removed
before installing a
child seat with
a
backrest on a passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event
of sharp braking. Refit the head restraint
once the child seat has been removed.
