Safety
Electronic Stability Programme incorporating
the following systems:


- the anti-lock braking system (ABS) and the electronic brake force distribution (EBFD),

- the emergency braking assistance,

- the anti-slip regulation (ASR) or tractioncontrol,

- the dynamic stability control (DSC).






























Electronic stability programme (ESP)
Definitions
Anti-lock braking system (ABS)and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and provides improved control in corners, in par ticular on poor or slippery road surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to reach the optimum braking pressure more quickly and therefore reduce the stopping distance. It is triggered in relation to 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.

Anti-slip regulation (ASR)

The ASR system (also known as Traction Control) optimises traction in order to avoid
wheel slip b
y acting on the brakes of the drivingwheels and on the engine. It also improves
the directional stability of the vehicle onacceleration.


Dynamic stability control (DSC)

If there is a difference between the path followed by the vehicle and that required bythe driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws of physics.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving onsnow: intelligent traction control.This system detects situations of difficult surface adhesion that could make it difficult to move off or make progress on deep fresh snow
or compacted snow.In these situations, the intelligent traction control
limits the amount of wheel slip to provide the best traction and trajectory control
for your vehicle.

Operation


Anti-lock braking system (ABS)
and electronic brake force
distribution
(EBFD)
In emergency braking, press very firmly without releasing the pressure.

When changing wheels (tyres and rims),make sure that these are approved for your vehicle.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal. When this warnin
g lamp comes on,
accompanied by an audible signal
and a message, it indicates that
there is a fault with the ABS, which
could cause loss of control of the vehicle whenbraking.
When this warnin
g lamp comes on, coupled with the STOPwarning lamp,
accompanied by an audible signal
and a message, it indicates that
th
ere is a fault with the electronic brake forcedistribution (EBFD), which could cause loss of control of the vehicle when braking.
You must stop as soon as it is safe to do so. In both cases, contact a CITROËN dealer or a qualified workshop. The use o
f snow tyres is strongly recommended on surfaces offering low levels of adhesion.

Safety
Dynamic stability control (DSC)

Activation
This system is activated automatically eachtime the vehicle is started.
It comes into operation in the event of a grip or
tra
jectory problem.
This is indicated by
flashing of thiswarning lamp in the instrument panel.

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate
the DSC system, so that the wheels can move freely and regain grip.

The DSC system offers exceptional
safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed.
The correct operation of the system depends on obser vation of the manufacturer's recommendationsregarding the wheels (tyres and rims),the braking components, the electronic components and the CITROËN assembly and operation procedures.
After an impact, have the systemchecked by a CITROËN dealer or a qualified workshop.

Operating fault


If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, this indicates a fault
with the s
ystem.
Contact a CITROËN dealer or a qualifiedworkshop to have the system checked.
Reactivation
The system is reactivated automatically each
time the ignition is switched back on or from 30 mph (50 km/h).
) Press the button.
This warnin
g lamp and the indicator
lamp in the button come on:
the DSC s
ystem no longer acts on
the operation of the engine.
)
Press the button again to
reactivate it manually. But it is recommended that the s
ystem be
reactivated as soon as possible.

Seat belts

Rear seat belts

The rear seats are each fitted with a seat belt,
three-point anchorages with iner tia reel and
force limiter (except for the centre rear seat).
Fastening
)Pull the strap, then inser t the tongue in thebuckle.)Check that the seat belt is fastenedcorrectly by pulling the strap.



Unfastening
)Press the red button on the buckle.)Guide the seat belt as it reels in. Th
e front seat belts are fitted with a pretensioning and force limiting system.
This s
ystem improves safety in the frontseats in the event of a front or side impact.
Depending on the severity of the impact, thepretensioning 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, soimproving their protection.

)To adjust the anchorage point, squeeze the control and slide it until you find a notch.



From approximatel
y 12 mph (20 km/h),
the warning lamp(s) flash for two
minutes accompanied by an audible signal. Once these two minutes have
elapsed, the warning lamp(s) remain on until the
driver or one or more passengers fasten their
seat belt.

The driver must ensure that passengers usethe seat belts correctly and that they are allrestrained 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 isstowed automatically when not in use.
Before and after use, ensure that the seatbelt is reeled in correctly.
The lower part of the strap must be positioned as low as possible on the pelvis.
The upper par t must be positioned in the hollow of the shoulder.
The inertia reels are fitted with an automatic locking device which comes into operation inthe event of a collision, emergency braking or if the vehicle rolls over. You can release the device by pulling firmly on the strap and 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 shor ter 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.

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 nottwist,

- be used to restrain only one person,

- not bear any trace of cuts or fraying,

- not be converted or modified to avoidaffecting its per formance.
In accordance with current safetyregulations, for all repairs on your vehicle, 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 soapywater or a textile cleaning product, sold by CITROËN dealers.
After folding or moving a seat or rear benchseat, 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 impact
, thepretensioning device may be deployedbefore and independently of the airbags.Deployment of the pretensioners isaccompanied by a slight discharge of harmless smoke and a noise, due to theactivation of the pyrotechnic car tridge incorporated in the system. In all cases, the airbag warning lampcomes on.Following an impact, have the seat belts system checked, and if necessary replaced,
by a CITROËN dealer or a qualified workshop.

173Safety
Airbags

System designed to maximise the safety of the
occupants
(with the exception of the rear centrepassenger) in the event of violent collisions.
It supplements the action of the force-limitingseat belts (with the exception of the rear centrepassenger).
I
f 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 deployed instantly and protect
the occupants of the vehicle (with theexception 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,

- in the case of a minor or rear impact or incertain roll-over conditions, the airbags
will not be deployed; the seat belt alone is
sufficient to provide optimum 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 the airbag(s) is accompanied by a slight emission of harmless smoke and a noise, due to the activation of the pyrotechniccar tridge incorporated in the system. This smoke is not harmful, but sensitiveindividuals may experience slight irritation.
The noise of the detonation may resultin a slight loss of hearing for a shor ttime.

Front airbags


Deployment

The airbags are deployed simultaneously, unless
the passenger's front airbag is deactivated, in the event of a serious front impact to all or part of thefront impact zone A, in the longitudinal centreline of the vehicle on a horizontal plane and directedfrom the front to the rear of the vehicle.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the steering wheel, driver's side, and the dashboard,
passen
ger's side to cushion their for ward
movement. S
ystem which protects the driver and front
passenger in the event of a serious front impact
in order to limit the risk of injury to the head and
thorax.
The driver's airbag is fitted in the centre of the steering wheel; the front passenger's airbag isfitted in the dashboard above the glove box.

Deactivation
Only the passenger's front airbag can be deactivated:)with the ignition off, inser t the key in thefpassenger airbag deactivation switch, )turn it to the "OFF"position,)then, remove the key keeping the switch in
the new position.
Accordin
g to version, this warning lamp comes on either in the instrument panel
or in the seat belt and passenger's frontairbag warning lamp display when the ignition is on
and until the airbag is reactivated.
To assure the safety of your child,the passenger's front airbag must be deactivated when you install a "rear facing" child seat on the front passenger seat. Otherwise, the child would risk beingseriously injured or killed if the airbag were deployed.
If even one of the two airbag warning lamps comes on continuously, donot install a child seat on the frontpassenger seat.
Have it checked by a CITROËN dealer or qualified workshop.



Reactivation

When you remove the child seat, with
the ignitionoff, turn the switch to the f"ON"
position to reactivate the airbag and so assure
the safety of your front passenger in the event
of an impact.
With the ignition on, this warninglamp comes on in the seat belt andpassenger's front airbag warninglamp display for approximately
one minute, if the passenger's front
airbag is activated.


Operating fault

If this warning lamp comes on in theinstrument panel, accompanied by an
audible warning and a message in theinstrument panel screen, contact a CITROËN dealer or a qualified workshop to have
the system checked. The airbags may no longer
be deployed in the event of a serious impact.
If this warnin
g lamp flashes, contact
a CITROËN dealer or a qualified workshop. The passenger's front
airbag may no longer be deployed in
the event of a serious impact.
