Citroen DS3 2011.5 1.G Owner's Manual

149Safety
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 theresistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.














Trajectory control systems
Anti-slip regulation (ASR)
and electronic stability
pro
gramme (ESP)
The anti-slip regulation (also known as TractionControl) optimises traction to prevent skiddingof the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability programme acts on the
brake of one or more wheels and on the engine
to keep the vehicle on the trajectory required
by the driver, within the limits of the laws of physics.

Activation

These systems are activated automaticallyeach time the vehicle is started.
They come into operation in the event of a gripor trajectory problem.
This is indicated b
y flashing of this
warning lamp in the instrument panel.

Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on softground...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can
move freely and regain grip. )Press the "ESP OFF"button, located on
the left below the steering wheel.

If this warnin
g lamp comes on in the
instrument panel and the indicator
lamp in the button comes on, this
indicates that the ASR and ESP
systems are deactivated.

Reactivation

These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h) except 1.6 litre (THP 150, THP 155 and THP 160) and
RACING petrol engines. )
Press the "ESP OFF"
button again to
reactivate them manually.

Operating fault

The ESP/ASR systems offer exceptional safety in normal driving, butthis should not encourage the driver to take extra risks or drive at high speed.
The correct functioning of these systems depends on obser vation of themanufacturer's recommendations on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair procedures.
After an impact, have these systems checked by a CITROËN dealer or a qualified workshop.

If this warning lamp comes on, accompanied by an audible signal and amessage in the multifunction screen, this
indicates a mal
function of these systems. Have it checked by a CITROËN dealer or a qualified workshop.

Safety
Seat belts


Front seat belts


The front seat belts are fitted with apretensioning and force limiting system.
This system improves safety in the frontseats in the event of a front or side impact.
Dependin
g 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 i
gnition is on.
The force limiter reduces the pressure of the
seat belt on the chest of the occupant, so
improving their protection.Fastening
) Pull the strap, then inser t the tongue in
the buckle.) Check that the seat belt is fastened correctly by pulling the strap.

Unfastening
)

Seat belt not fastened/unfastened warning lamp
When the ignition is switched on,
this warning lamp comes on in the
instrument panel, if the driver and/or thefront passenger has not fastened their seat belt.
From approximately 12 mph (20 km/h)
this warning lamp flashes for two minutes
accompanied by an audible signal of increasingvolume. Once these two minutes have elapsed,
this warning lamp remains on until the driver and/or the front passenger fastens their seat belt.

Rear seat belts

Fastening
)
Pull the strap, then inser t the tongue in
the buckle.) Check that the seat belt is fastened correctly by pulling the strap.


Unfastening
)Press the red button on the buckle.)Guide the seat belt as it is reeled in.

The rear seats are each
fitted with a three-point
inertia reel seat belt.

153Safety
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 asthey will not fulfil their role fully.
The seat belts are fitted with an inertia reel permitting automatic adjustment of the lengthof 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 bepositioned 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 releasethe device by pulling firmly on the strap and releasing it so that it reels in 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 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 safety regulations, for all repairs on your vehicle, go to aqualified 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.
Recommendations for children
Use a suitable child seat if the passenger
is less than 12 years old or shor ter thanone and a half metres.Never use the same seat belt to securemore than one person. Never allow a child to travel on your lap.
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 tothe activation of the pyrotechnic car tridgeincorporated 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 qualifiedworkshop.

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-limiting
seat belts (with the exception of the rear centrepassenger).
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 airbagsare deployed instantly and protect the
occupants of the vehicle (with the exception
of the rear centre passenger); immediately after the impact, the airbags deflate rapidlyso that they do not hinder visibility or the
exit of the occupants,
- in the case of a minor or rear impact or incer tain roll-over conditions, the airbags
will not be deployed; the seat belt alone is
sufficient to provide optimum protection in
th
ese situations.
The airbags do not operate when theignition 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.

Impact detection zones
A.Front impact zone.
B.Side impact zone.
Deployment of the airbag(s) is
accompanied by a slight emissionof harmless smoke and a noise, dueto the activation of the pyrotechnic cartridge incorporated in the system.
This smoke is not harmful, but sensitive individuals may experience slightirritation.
The noise of the detonation may result ina slight loss of hearing for a shor t time.

Safety
Front airbags
System which protects the driver and frontpassenger in the event of a serious front impact
in order to limit the risk of injury to the head and chest.
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.
Deployment
The airbags are deployed simultaneously,unless the passenger's front airbag is
deactivated, in the event of a serious frontimpact applied to all or par t 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 head-
thorax of the front occupant of the vehicle
and the dashboard to cushion their forward
movement.

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.
This warnin
g lamp comes on in the
instrument panel when the ignition is
on and until the airbag is re-activated.
To assure the safety of your child,the passenger's front airbag mustbe deactivated when you install a "rear facing" child seat on the front passenger seat. Other wise, the child would risk beingseriously injured or killed if the airbag were deployed.

Reactivation

When you remove a child seat that has been
fitted "rear wards facing", turn switch to the
"ON"
position to re-activate the airbag and so
assure the safety of your front passenger in theevent of an impact.
With the i
gnition on, this warning lampcomes on in the instrument panel for approximately one minute, if thepassenger's front airbag is activated.


Operating fault
If this warning lamp flashes, contact
a CITROËN dealer or a qualified
workshop. The passen
ger's front
airbag may no longer be deployed in the event
of a serious impact.
If at least one of the two airbag
warning lamps come on continuously, do not install a child seat on the front passenger seat.
Have it checked by a CITROËN dealer or a qualified workshop.
If this warnin
g lamp comes on in the instrument panel, accompanied byan audible warning and a message in
the multifunction screen, contact a CITROËN
dealer or qualified workshop to have thesystem checked. The airbags may no longer be
deployed in the event of a serious impact.
