SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:
- anti-lock braking system (ABS),
- electronic brake force distribu-tion (EBFD),
- emergency braking assistance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the
stability and manoeuvrability of your
vehicle when braking, in particular
on poor or slippery surfaces.
Activation
The anti-lock braking system comes
into operation automatically when
there is a risk of wheel lock.
Normal operation of the ABS may
make itself felt by slight vibration of
the brake pedal. Operating fault
When braking in an emergency,
press very fi rmly without releasing
the pressure. If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
it indicates a malfunction of the anti-
lock braking system which could re-
sult in loss of control of the vehicle
when braking.
If this warning lamp comes on,
together with the STOP and

ABS warning lamps, accom-
panied by an audible signal
and a message on the multifunction
screen, it indicates a malfunction of
the electronic brake force distribution
which could result in loss of control of
the vehicle when braking.

You must stop as soon as it is
safe to do so.
In either case, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
Emergency braking assistance
System which, in an emergency,
enables you to obtain the optimum
braking pressure more quickly, thus
reducing the stopping distance.
Activation
It is triggered by the speed at which
the brake pedal is pressed.
The effect of this is a reduction in
the resistance of the pedal and an
increase in braking effi ciency.
When braking in an emergency,
press fi rmly without releasing the
pressure.

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
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
re-winds 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, 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 regu-
larly by a CITROËN dealer and par-
ticularly 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
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 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.

AIRBAGS

System designed to maximise the
safety of the occupants (with the
exception of the rear centre pas-
senger) in the event of violent col-
lisions. It supplements the action of
the force-limiting seat belts.
If a collision occurs, the electronic
detectors record and analyse the
front and side impacts sustained in
the impact detection zones:
- in the case of a serious impact,
the airbags are triggered instant-
ly and protect the occupants of
the vehicle (with the exception of
the rear centre passenger); im-
mediately after the impact, the
airbags defl ate rapidly so that
they do not hinder visibility or the
exit of the occupants,
- in the case of a minor or rear impact or in certain roll-over
conditions, the airbags will not
be triggered; the seat belt alone
is suffi cient to provide optimum
protection in these situations.
The airbags do not operate
when the ignition is switched
off.
This equipment will only operate
once. If a second impact occurs (dur-
ing the same or a subsequent acci-
dent), the airbag will not operate. Impact detection zones

A. Front impact zone.

B. Side impact zone.
Triggering of the airbag(s) is ac-
companied by a slight emission of
harmless smoke and a noise, due to
the activation of the pyrotechnic car-
tridge incorporated in the system.
This smoke is not harmful, but sen-
sitive individuals may experience
slight irritation.
The noise of the detonation may
result in a slight loss of hearing for
a short time. Front airbags
System which protects the head and
chest of the driver and front passenger
in the event of a front impact.
The driver's airbag is incorporated
in the centre of the steering wheel;
the front passenger's airbag is incor-
porated in the dashboard above the
glove box.
Activation
The airbags are triggered simultane-
ously, unless the passenger's front
airbag is deactivated, in the event of
a serious front impact applied to all
or part of the front impact zone
A ,
in the longitudinal centreline of the
vehicle on a horizontal plane and di-
rected from the front to the rear of
the vehicle.
The front airbag infl ates between the
front occupant of the vehicle and the
dashboard to cushion their forward
movement.

audible signal is heard.

Maximum application is essential:
- when towing a caravan or a trail- er, if the automatic functions are
activated but you are applying
the parking brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- when towing, when loaded or when parking on a gradient, turn
the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer.

Dynamic emergency braking
In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) a con-
tinuous pull on the control lever A will
stop the vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed in the
multifunction screen:
- "Parking brake faulty".
- "Parking brake control faulty". If a failure of the ESP sys-
tem is signalled by the light-
ing of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull-release"
actions on control lever A .
The dynamic emergency
braking must only be used in
exceptional circumstances.
