SAFETY
SEAT BELTS

Front seat belts

The front seat belts are fi tted with a
pretensioning system and force limiter.
This system improves safety in the front
seats in the event of a front impact.
Depending on the seriousness of the
impact, the pretensioning system in-
stantly tightens the seat belt against
the body of the occupant.
Fastening


)
Pull the belt down in front of you
in a steady movement, making
sure that it does not become
twisted.

)

Press the fastening into its buckle.

)
Check that it is properly secured
and that the automatic locking
mechanism operates correctly
by pulling sharply on the belt
strap.

)
The lap strap should be posi-
tioned as low down as possible in
the lap and as tight as possible.

)
The diagonal strap should be
positioned across the chest and
away from the neck.
Each belt has a reel that adjusts its
length automatically to the girth of
the seat occupant.

Height adjustment
The pretensioning seat belts are
active when the ignition is on.
The force limiter reduces the pres-
sure of the seat belt against the
chest of the occupant, so increasing
his protection.

When correctly adjusted, the seat
belt shoulder strap falls over the
middle of the shoulder.


)
To adjust the belt, squeeze the
control and slide it in the direc-
tion required.



Unfastening


)
To unfasten the belt, press on
the red button in the buckle.
The belt retracts automatically when
not in use.

Third row rear seat belts
(Grand C4 Picasso)

Instructions for use of
the third row passenger seat belts
Take care to attach the third-row
passenger seat belts securely to the
rings provided for this purpose.

Do not attach the belts to the lug-
gage anchoring rings marked
with a red cross, as shown in the
illustration.



Stowing the tongue of
the third-row seat belt


)
Secure the tongue in the location
provided on the rear pillar trim.
The third-row passenger seat belts
that are not being used can be
stowed in order to free up loadspace
and facilitate use of the luggage
cover.

Before use:

To avoid damaging or jamming the
seat belts, stow them carefully on
the sides of the seat backrests.

VIII
134
SAFETY





The driver must ensure that passen-
gers use the seat belts correctly and
that they are all restrained securely
before setting off.
Wherever you are seated in the ve-
hicle, always fasten your seat belt,
even for short journeys.
Do not interchange the seat belt
buckles as they will not fulfi l their
role fully.
The seat belts are fi tted 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 fi tted 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 re-
lease the device by pulling fi rmly on
the strap and releasing it so that it
reels in slightly. In order to be effective, a seat belt
must:


- be tightened as close to the body
as possible,

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

-
be used to restrain only one person,

- not bear any trace of cuts or fraying,


- not be converted or modifi ed to
avoid affecting its performance.
Recommendations for children
Use a suitable child seat if the pas-
senger is less than 12 years old or
shorter than one and a half metres.
Never use the same seat belt to se-
cure more than one person.
Never allow a child to travel on your
lap.
In accordance with current safety
regulations, for all repairs on your
vehicle, go to a qualifi ed workshop
with the skills and equipment need-
ed, which a CITROËN dealer is able
to provide.
Have your seat belts checked regu-
larly by a CITROËN dealer or a
qualifi ed 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.
In the event of an impact

Depending on the nature and se-
riousness of the impact
, the pre-
tensioning device may be deployed
before and independently of the
airbags. Deployment of the preten-
sioners 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 neces-
sary replaced, by a CITROËN dealer
or a qualifi ed workshop.

VIII
138
SAFETY













For the airbags to be fully
effective, observe the following
safety rules:

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.
If possible, do not smoke as deploy-
ment 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.



Lateral airbags
Use only approved covers on the seats,
compatible with the deployment the
lateral airbags. For information on the
range of seat covers suitable for your
vehicle, you can contact a CITROËN
dealer (see "Practical information - §
Accessories").
Do not fi x 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 fi x or attach anything to the
roof. This could cause injury to the
head if the curtain airbag is de-
ployed.
If fi tted on your vehicle, do not re-
move the grab handles installed on
the roof, they play a part in securing
the curtain airbags.
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 qualifi ed workshop.
Even if all of the precautions men-
tioned 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 infl ates
almost instantly (within a few mil-
liseconds) then defl ates within the
same time discharging the hot gas
via openings provided for this pur-
pose.

PRACTICAL INFORMATION
ROOF BARS

For your safety and to avoid damage
to the roof and tailgate, the design of
your vehicle requires the use of roof
bars and roof boxes that are tested
and approved by CITROËN.
Regardless of the type of load car-
rier to be mounted on the roof (roof
box, bicycle carrier, ski carrier...),
you must fi t transverse roof bars.


Recommendations



)
Distribute the load evenly, avoid-
ing overloading on one side.

)
Arrange the heaviest part of the
load as close as possible to the
roof.

)
Anchor the load securely and fi t
a warning fl ag part of it is over-
hanging.

)
Drive gently, as the vehicle will
be more liable to the effects of
side winds (vehicle stability may
be altered).

)
Remove the roof bars as soon
as they are no longer needed.



Bicycle carrier

Do not attach a strap-fi tting bicycle car-
rier to the following vehicle versions:


- C4 Picasso 5-seater (all versions);

- C4 Picasso 7-seater version with
opening rear screen.



Maximum load, distributed
over the roof bars (for a loading
height not exceeding 40 cm,
except bicycle carrier): 80 kg.
If the height exceeds 40 cm, adapt
your speed to the profi le of the road
to avoid damaging the roof bars
and the fi xings on the roof.
Please refer to national legislation
in order to comply with the regula-
tions concerning the transport of
objects which are longer than the
vehicle.

* According to country.
