ing wheel.
HAZARD WARNING LAMPS
Press the button, the direction indica-
tors fl ash.
They can operate with the ignition off.
ANTI-LOCK BRAKING SYSTEM (ABS) AND BRAKING SYSTEMS (EBFD AND CSC * )
When the vehicle is being driv-
en, illumination of this warning
lamp indicates that the parking
brake is still on or has not been
properly released.

When parking on a slope,
direct your wheels towards
the pavement and pull the
parking brake
on
.
PARKING BRAKE
Applying
Pull the parking brake to immobilise
your vehicle.
When changing wheels
(tyres), make sure that these
are approved.
The anti-lock braking system comes
into operation automatically when
there is a risk of wheel lock.
Releasing
Pull on the handle and press the button
to release the parking brake.
* The CSC system is linked with the EBFD on vehicles which are not fi tted
with ASR/ESP systems.
EMERGENCY BRAKING ASSISTANCE
The ABS, in conjunction with the EBFD and CSC * braking systems, increases
the stability and manoeuvrability of
your vehicle on braking and provides
improved control, in particular on poor
or slippery road surfaces.
The ABS prevents wheel lock in the
event of emergency braking.
The EBFD and CSC * systems pro-
vide full control of the braking pres-
sure wheel by wheel. A distribution
between:
- the front and the rear in the case of the EBFD (Electronic Brake
Force Distribution),
- the left and the right in the case of the CSC * (Cornering Stability
Control).
In an emergency, this system enables you to reach the optimum braking
pressure more quickly and therefore
reduce the stopping distance.
It is triggered by the speed at which
the brake pedal is pressed. This is
felt by a reduction in the resistance
of the pedal and an increase in the
effectiveness of the braking.

SAFETY
When this warning lamp
comes on, it indicates that
there is a fault with the ABS,
which could cause a loss of
control of the vehicle when
braking.
Contact a CITROËN dealer or a
qualifi ed workshop.
When these warn-
ing lamps come on
simultaneously, it
indicates that there
is a fault with the braking system or
that the parking brake has not been
released fully, which can cause a
loss of control of the vehicle when
braking.

You must stop as soon as it is safe
to do so.
Contact a CITROËN dealer or a
qualifi ed workshop.
Normal operation of the ABS
may make itself felt by slight
vibrations of the brake pedal.

In emergency braking,
press very fi rmly without
releasing the pressure.
ANTI-SLIP REGULATION (ASR) AND ELECTRONIC STABILITY PROGRAMME (ESP)
Operating check
Operation of the ASR and ESP
systems
When one of these two sys-
tems is operating, this warning
lamp comes on.
If a fault occurs with the
systems, this warning lamp
comes on. The ASR/ESP systems offer
exceptional safety during nor-
mal driving, but this should not encourage the driver to take
extra risks or drive at high speed.
Correct operation of these systems
depends on observation of the manu-
facturer's recommendations regarding
the wheels (tyres and rims), the brak-
ing components and the electronic
components as well as the repair pro-
cedures use by a CITROËN dealer or
qualifi ed workshop.
After an impact, have these systems
checked by a CITROËN dealer or a
qualifi ed workshop.
Contact a CITROËN dealer or a
qualifi ed workshop to have the sys-
tems checked.
These systems are linked and sup-
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act-
ing on the brakes of the driving wheels and on the engine. It also allows the
directional stability of the vehicle to
be improved on acceleration.
If there is a variation between the tra-
jectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
brake of one or more wheels and on
the engine to put the vehicle back on
course, within the limits of the laws
of physics.

SEAT BELTS Pretensioning front seat
belts with force limiter
Safety in the event of front
impacts has been improved
by means of the introduction of pre-
tensioning seat belts with force lim-
iter for the front seats. Depending on
the force of the impact, the preten-
sioning system instantly tightens the
seat belts and pulls them against the
body of the occupants.
The pretensioning seat belts are ac-
tive when the ignition is on.
The force limiter reduces the pressure
of the seat belt on the chest of the oc-
cupant, increasing their protection. 3-door
5-door
Rear seat belts
The rear seats are equipped with two
three-point inertia reel seat belts.
You can store the seat belt buckles in
the housing
A .
Fastening/Unfastening the seat
belts
Pull the strap, then insert the buckle
into the stalk.
Check that the seat belt is fastened
correctly by pulling the strap.
To unfasten the seat belts, press the
button on the stalk.

61
SAFETY
The driver must ensure that
the passengers use the seat
belts correctly and that they
are all properly restrained
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.
If the seats have armrests * , the lap
part of the seat belt must always
pass under the armrest.
The seat belts are fi tted with an in-
ertia reel permitting automatic adjust-ment of the length of the strap to your
size. The seat belt is stored automat-
ically 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, on emergency braking or if the
vehicle 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 adult 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 transformed or modifi ed to avoid altering its
performance.
In accordance with current safety
regulations, all repairs and checks
must be carried out by a CITROËN
dealer who can guarantee that the
work is carried out correctly, or quali-
fi ed workshop.
Have your seat belts checked regu-
larly by a CITROËN dealer or a quali-
fi ed workshop 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 rolled up correctly. Recommendations for children:
- use a suitable child seat if the
passenger is less than 12 years
old or shorter than one metre
fi fty,
- do not use the strap-guide * when a child seat is installed.
- never use the same seat belt to secure more than one person,
- never allow a child to travel on your lap.

Depending on the nature and se-
riousness of the impacts , the pre-
tensioning device may be triggered
before and independently of the air
bags. Triggering of the pre-tension-
ers is accompanied by a slight emis-
sion of harmless smoke and a noise,
due to the activation of the pyrotech-
nic cartridge incorporated in the sys-
tem.
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.

AIRBAGS
FRONT AIRBAGS
Front airbag fault
Flashing indicates an airbag fault, contact a CITROËN
dealer or a qualifi ed work-
shop to have the system
checked. The airbags may
no longer be deployed in the event of
a serious impact.

Note: the gas escaping from
the airbags can be a minor
irritant.
Immediately after the impact, the air-
bags defl ate rapidly so that they do
not hinder the visibility of the occu-
pants nor their exit if necessary from
the vehicle. The air bags are not de-
ployed in the case of minor impacts,
rear impacts or in certain roll-over
conditions. The seat belt is suffi cient
to ensure maximum protection in
these situations. The seriousness of
a collision depends on the nature of
the obstacle and the speed of the ve-
hicle at the moment of the collision.

Airbags only operate when the igni-tion is switched on. When they are
deployed, a noise is heard during
infl ation.
Impact detection zones
A. Front impact zone.

B. Side impact zone.
The airbags have been designed to
maximise the safety of the occupants
in the event of serious collisions. They
work in conjunction with the force-
limiting seat belts. The electronic
detectors register and analyse any
abrupt deceleration of the vehicle in
the impact detection zones (see dia-
gram): if the deployment threshold is
reached, the airbags infl ate instantly
and protect the occupants of the ve-
hicle.
These are fi tted in the centre of the steer-
ing wheel for the driver and in the dash-
board for the front passenger. They are
deployed simultaneously, except in cases
where the passenger's airbag is deacti-
vated, in the event of a serious front im-
pact applied in the impact zone
A in the
longitudinal centreline of the vehicle, on
a horizontal plane and from the front of
the vehicle towards the rear. The airbag
infl ates between the front occupant of the
vehicle and the dashboard to cushion his
forward movement. The airbags there-
fore limit the risk of injury to the head and
chest.

SAFETY
Deactivating the passenger
airbag

To ensure the safety of your child,
it is essential to deactivate the
passenger airbag when you install a "rear-facing" child seat on the
front passenger seat. Otherwise,
the child would risk being seri-
ously injured or killed if the air bag
were to infl ate.

 With the ignition switched off ,
insert the key into the passenger
airbag deactivation switch 1 ,
turn it to the "OFF" position,
then remove the key keeping the
switch in this position.
In the "OFF" position, the passen-
ger airbag will not be deployed in the
event of an impact.
As soon as the child seat is removed,
turn the airbag switch to the "ON"
position to re-activate the airbag and
thus ensure the safety of your pas-
senger in the event of an impact. If the passenger airbag is de-
activated, the warning lamp
in the instrument panel re-
mains on until the passenger
airbag is reactivated.
Flashing indicates a fault
with at least one of these
airbags.
Contact a CITROËN deal-
er or a qualifi ed workshop
to have the system checked. The
airbags may no longer be deployed
in the event of a serious impact.
Deactivation (check)
Airbag fault
* According to version.
LATERAL AIRBAGS * AND CURTAIN AIRBAGS *
The lateral airbags are built into the
front seat backs on the door side.
The deployment of these airbags re-
quires a serious side impact applied
in the side impact zone B , perpen-
dicular to the longitudinal centreline
of the vehicle, on a horizontal plane
and from the outside of the vehicle
towards the inside. The lateral airbag
infl ates between the front occupant
of the vehicle and the door trim panel.
It therefore limits the risk of injury to
the chest.
The rear lateral airbags afford the
rear passengers the same protection
which the front lateral airbags offer
the front passengers.
The curtain airbags are built into the
headlining. The curtain airbag infl ates between
the front or rear occupant and the
windows. It therefore limits the risk
of head injuries. In the event of a
minor impact or bump on the side of
the vehicle or if the vehicle rolls over,
the airbag may not be deployed. The
airbag is not deployed in the event of
a front or rear collision.

SAFETY
For the front, lateral and
curtain airbags to be fully
effective, observe the fol-
lowing safety rules:
Wear a correctly adjusted seat belt.
Sit in a normal upright position.
Do not leave anything between the
occupants and the airbags (child,
animal, object...). This could hamper
the operation of the airbags or injure
the occupants.
All work on the airbag systems is
strictly prohibited unless it is car-
ried out by qualifi ed personnel of the
CITROËN dealer network or a quali-
fi ed workshop.
After an accident or if the vehicle has
been stolen or broken into, have the
airbag systems checked. 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.
Smoke as little as possible; 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.
Curtain airbags
Do not fi x or attach anything to the
pillars or the roof. This could cause
injury to the head when the curtain
airbag infl ates.
The deployment of an airbag or air-
bags is accompanied by a slight
emission of harmless smoke and
a noise due to the activation of the
pyrotechnic cartridge incorporated in
the system. This smoke is not harm-
ful but sensitive individuals may ex-
perience some irritation.
The detonation noise may result in
a slight loss of hearing for a short
time.
Even if all of the precautions men-
tioned are observed, injury or slight
burns to the head, chest or arms
when the air bag is deployed can-
not be ruled out. Indeed, the bag in-
fl ates almost instantly (approximately
30 milliseconds) then defl ates within
the same time discharging hot gas
via the openings provided for this
purpose.
This equipment will only operate
once. If a second impact occurs
(during the same or a subsequent
accident), the airbag will not infl ate.
Lateral airbags
Only put approved covers on the seats,
these will not hamper the infl ation of the
lateral airbags. Contact a CITROËN
dealer or a qualifi ed workshop.
Do not fi x or attach anything to the
front seat backs. This could cause
injury to the chest or arms when the
lateral airbag infl ates.
Do not sit with the upper part of the
body any nearer to the door than
necessary.
