Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-
a
nti-lock braking system (ABS),
-

e
lectronic brake force distribution (EBFD).
Braking assistance systems
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 sur faces.
Activation
The anti-lock braking system is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
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 the vehicle is stationary
If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop as
soon as possible.
When braking in an emergency, press
very firmly without releasing the
pressure. The warning lamp comes on for a few
seconds when the ignition is switched on
(ON position). If it does not switch off or
does not come on, contact a CITROËN
dealer or a qualified workshop.

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.

Airbags
System designed to contribute towards
improving the safety of the occupants (with
the exception of the rear centre passenger)
in the event of violent collisions. The airbags
supplement the action of the force-limiting
seat belts (with the exception of the centre rear
passenger).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-
i
n the case of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of the occupants
of the vehicle (with the exception of the
rear centre passenger); immediately after
the impact, the airbags deflate rapidly so
that they do not hinder visibility or the exit
of the occupants,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
protection in these situations.
The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once.
If a second impact occurs (during the
same or a subsequent accident), the
airbag will not be deployed again. Deployment of one or more of the
airbags is accompanied by a slight
emission of smoke and a noise, due
to the activation of the pyrotechnic
cartridge incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience slight
irritation.
The noise of detonation related to the
deployment of one or more airbags may
result in a slight loss of hearing for a
short time.
Impact detection zones

B. S
ide impact zone.
Front airbags
Deployment
The airbags are deployed, except the
passenger's front airbag if it 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 directed from the front to
the rear of the vehicle.
The front airbag inflates between the front
occupant of the vehicle and the dashboard to
cushion their for ward movement. System which contributes toward improving
protection for the head and chest of the driver
and front passenger in the event of a front
impact.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger's airbag is
fitted in the dashboard above the glove box.

emove the compressor and stow the kit.Do not operate the compressor for more
than 10 minutes continuously.
If the compressor seems extremely
hot, switch it off and disconnect it
immediately. Leave it to cool for at least
30 minutes.
As soon as possible after a repair using
the kit, go to a CITROËN dealer or a
qualified workshop.
Tell the technician that you have used
the kit. After checking, the technician
will advise you whether the tyre can be
repaired or must be replaced.
If the vehicle is fitted with under-
inflation detection, the under-inflation

pressure using the compressor. If the
pressure has dropped slightly, inflate the
tyre again to the specified figure. Carry

(10 km) or 5 minutes: if the pressure
has not held at the specified figure, this
indicates that the puncture repair has not
sealed; contact a CITROËN dealer or a
qualified workshop for roadside assistance.
