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.

Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the
seat belt on the chest of the occupant,
so improving their protection.
Fastening

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
A. Front impact zone.
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.

Deactivation
Only the front passenger's airbag can be
deactivated:
F
i
nsert the key in the passenger airbag
deactivation switch A,
F

t
urn it to the "OFF" position,
F

r
emove the key. This warning lamp comes on in
the centre console panel when the
ignition is on and until the airbag is
reactivated. To ensure the safety of your child, the
passenger's airbag must be deactivated
when you install a "rear ward facing"
child seat on the front passenger seat.
Other wise, the child would risk being
seriously injured or killed if the airbag
were triggered.
If the airbag warning lamp and the
display come on continuously, do not
install a "rear ward facing" child seat on
the front passenger seat.
Contact a CITROËN dealer or a
qualified workshop without delay.
Reactivation
When you remove the "rear ward facing" child
seat, turn switch A to the "ON" position to
reactivate the airbag and so ensure the safety
of your front passenger in the event of an
impact.
The associated warning lamp goes off.
Operating fault
If this warning lamp comes on in the
instrument panel, accompanied by a
message, contact a CITROËN dealer
or a qualified workshop without delay
to have the system checked. The
airbags may no longer be deployed in
the event of a serious impact.
