ADVICE ON CHILD SEATS
Installing a booster seat
The chest part of the seat belt must
be positioned on the child's shoulder
without touching the neck.
Ensure that the lap part of the
seat belt passes correctly over the
child's thighs.
CITROËN recommends the use of
a booster seat which has a back,
fi tted with a seat belt guide at
shoulder level. As a safety precaution, do not leave:
- one or more children alone and
unsupervised in a vehicle,
- a child or an animal in a vehicle which is exposed to the sun, with
the windows closed,
- the keys within reach of children inside the vehicle.
To prevent accidental opening of the
doors, use the "Child lock".
Take care not to open the rear win-
dows by more than one third.
To protect young children from the
rays of the sun, fi t side blinds on the
rear windows.
The incorrect installation of a child
seat in a vehicle compromises the
child's protection in the event of an
accident.
When installing a child seat using the
seat belt, check that the seat belt is
tightened correctly on the child seat
and that it secures the child seat
fi rmly on the seat of your vehicle.
Remember to fasten the seat belts
or the child seat harnesses
keeping
the slack in relation to the child's
body to a minimum, even for short
journeys.
For optimum installation of the
"forwards-facing" child seat, ensure
that the back of the child seat is in
contact with the back of the vehicle's
seat and that the head restraint does
not cause any discomfort.
If the head restraint has to be re-
moved, ensure that it is stored or
attached securely to prevent it from
being thrown around the vehicle in
the event of sharp braking. Children under the age of 10 must
not travel in the "forwards-facing"
position on the front passenger
seat, unless the rear seats are al-
ready occupied by other children,
cannot be used or are absent.
Deactivate the passenger air bag *
when a "rearwards-facing" child
seat is installed on the front seat.
Otherwise, the child would risk be-
ing seriously injured or killed if the
air bag were to infl ate.

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. 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 abdominal part of the strap
should be positioned as low
down as possible in the lap and
as tight as possible.

 The chest part should be posi-
tioned if possible in the channel
of the shoulder.
Each belt has a reel that adjusts its
length automatically to the girth of
the seat occupant.
Depending on the seriousness of the
impact, the pretensioning system in-
stantly tightens the seat belt against
the body of the occupant.
The pretensioning seat belts are ac-
tive when the ignition is on.
The force limiter reduces the pres-
sure of the seat belt against the
chest of the occupant, so increasing
their protection.

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 invert the seat belt buckles
as they will not fulfi l their role fully.
The seat belts are fi tted with an in-
ertia reel permitting automatic ad-
justment of the length of the strap
to your size. The seat belt is stored
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 au-
tomatic locking device which comes
into operation in the event of a colli-
sion, emergency braking or if the ve-
hicle rolls over. You can release the
device by pulling rapidly on the strap
and releasing it. In order to be effective, a seat belt:
- must be tightened as close to the
body as possible,
- must restrain one person of adult size only,
- must not bear any trace of cuts or fraying,
- must be pulled in front of you with a smooth movement, checking
that it does not twist,
- must not be altered or modifi ed to avoid altering 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, all repairs and checks
must be carried out by a CITROËN
dealer who guarantees that the work
is carried out correctly.
Have your seat belts checked regularly
by a CITROËN dealer and 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.
Depending on the nature and
seriousness of the impacts
, the
pre-tensioning device may be trig-
gered before and independently
of the airbags. Triggering of the
pre-tensioners is accompanied
by a slight discharge of harmless
smoke and a noise, due to the acti-
vation 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.

For the airbags to be fully
effective, observe the following
safety rules:
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 is
strictly forbidden unless it is carried
out by qualifi ed personnel of the
CITROËN network.
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 triggered
cannot be ruled out. The bag infl ates
almost instantly (within a few millisec-
onds) then defl ates within the same
time discharging the hot gas via open-
ings 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.
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.
Side airbags
Use only approved covers on the
seats. These will not hinder infl a-
tion of the side airbags. Consult a
CITROËN dealer.
Do not fi x or apply anything to the
seat backs. This could cause injury
to the chest or arms if the side air
bag is triggered.
Do not sit with the upper part of the
body any nearer to the door than
necessary. Curtain airbags
Do not fi x or apply anything to the
roof. This could cause injury to the
head if the curtain airbag is trig-
gered.
Do not remove the grab handles in-
stalled on the roof, they play a part
in securing the curtain airbags.

Refi tting the wheel Dimension of the spare wheel
If your spare wheel is of different
dimensions to those on the vehicle
(identifi ed by a label), it is essential
to use it only on a temporary basis,
to drive not above 50 mph (80 km/h)
and to have the original wheel refi t-
ted as soon as possible.

Switch on your hazard
warning lamps.

It is imperative to ensure
that the occupants get out of the
vehicle and wait in a safe location.

Never get underneath the vehi-
cle if it is supported only by the
jack; use an axle stand.

The jack is designed specifi cally
for your vehicle, do not use it for
other applications.

Refi t the repaired original wheel
as soon as possible.

With a spare wheel fi tted, drive
with caution.

The wheel should be correctly
positioned fl at in the centre of
its well. Light alloy wheels
If your vehicle is equipped with
light alloy wheels and a steel spare
wheel, then if fi tting the latter it is
normal to note that the heads of the
wheel bolts do not come to bear on
the wheel rim.
The steel spare wheel is secured
by the conical tapering of the wheel
bolts’ shafts, see diagram.
When refi tting the light alloy wheel,
ensure that the wheel bolt heads are
in undamaged condition.

 Refi t the wheel in place.

 Undo the yellow central screw by
a few turns, then position it at the
centre of the wheel.

 Do up the central screw until tight
so that the wheel is securely re-
tained in place.
