The driver must ensure that passengers use
the seat belts correctly and that they are all
restrained securely 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 are fitted with an automatic
locking device which comes into operation 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.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, refer to the "Child
seats" section.
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 bear any trace of cuts or fraying,
-

n

ot be converted or modified to avoid
affecting its performance.
In the event of an impact
Depending on the nature and
seriousness of the impact , the
pretensioning 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 belts
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
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.

Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the
occupants and the airbags (a child, pet,
object...). This could hamper the operation of
the airbags or injure the occupants.
After an accident or if the vehicle has been
stolen or broken into, have the airbag
systems checked.
All work on the airbag system must be
carried out by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. 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.
Knee airbag*
Do not sit with your knees any nearer to the
steering wheel than necessary.
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 fit or attach anything to the steering
wheel or dashboard, this could cause
injuries with deployment of the airbags.
For the airbags to be fully effective, observe the following safety rules:Lateral airbags

compatible with the deployment the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, you can

Do not fix or attach anything to the seat
backs (clothing...). This could cause injury
to the chest or arms if the lateral airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.

Curtain airbags
Do not fix or attach anything to the roof. This
could cause injury to the head if the curtain
airbag is deployed.

grab handles installed on the roof, they play
a part in securing the curtain airbags.
Avoid attaching a heavy object to the key as
it could become a dangerous projectile if the
