Citroen DS4 2012 1.G Owner's Manual

179Safety
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 (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
The anti-slip regulation (also known as traction control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.The electronic stability control 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.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving on snow: 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 snowor compacted snow.
In these situations, the intelligent tractioncontrol limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low levels of adhesion.

Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on softground...), if you are unable to make progress,it may be advisable to temporarily deactivate
these systems, so that the wheels can spinfreely and allow the vehicle to move.
) Press the "ESP OFF"
button,located near the steering wheel.

Reactivation
These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h).)
Press the "ESP OFF"
button again to
reactivate them manually.

Operating fault

The trajectory control systems offer increased 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 is assured provided thatmanufacturer's recommendations areobserved 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.
I
f this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, this
indicates a fault with these systems.
Have it checked by a CITROËN dealer or aqualified workshop.
It is recommended that the systems bereactivated as soon as possible.
If this warnin
g lamp comes on in the instrumentpanel and the indicator lamp in the buttoncomes on, this indicates that these systems aredeactivated.

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 ignition 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 fastenedcorrectly by pulling the strap.



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

Seat belt not fastened/unfastened warning lamp in the instrument panel
When the ignition is switched on,
this warning lamp comes on in the
instrument
panel if the driver and/or
the front 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.

When the ignition is switched on, with the
engine running or when the vehicle is moving at less than 12 mph (20 km/h), the corresponding warning lamps 3, 4 and 5
come on in red for approximately 30 seconds, if the seat belt is not
fastened.
When the vehicle is moving at more than 12 mph (20 km/h), the corresponding warning lamps 3,4and 5come on in red, accompanied by anaudible signal and a message in the screen, if a rear passenger has unfastened their seat belt. From approximatel
y 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 one or more rear 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 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 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.

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 benchseat, 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 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 the event of an impact
Depending on the nature andseriousness 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 theactivation of the pyrotechnic cartridge incorporated in the system.
In all cases, the airbag warning lampcomes on.
Following an impact, have the seat beltssystem checked, and if necessary replaced, by a CITROËN dealer or a qualified workshop.

Safety
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); immediatelyafter the impact, the airbags deflate rapidlyso that they do not hinder visibility or theexit 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
these 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), theairbag will not be deployed again.


Impact detection zones
A.Front impact zone.
B. Side impact zone.

Deployment of the airbag(s) isaccompanied 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.

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
thorax.
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.

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 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 thorax
and head of the front occupant of the vehicle
and the steerin
g wheel, driver's side, and the
dashboard, passenger's side to cushion their
forward movement.

Safety

Deactivation
Only the passenger's front airbag can be deactivated:)inser t the key in the passenger airbagdeactivation switch,)turn it to the "OFF"position, )then, remove the key keeping the switch in
the new position.

According to version, this warninglamp comes on in the instrumentpanel and/or in the seat belt and passenger's front airbag warning lamps displaywhen the ignition is on and until the airbag is
reactivated.
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 the child seat, turn the switch to the "ON"position to reactivate the airbag and so assure the safety of your front passenger in the event of an impact.
With the i
gnition on, this warninglamp comes on in the seat belt andpassenger's front airbag warning lamps display for approximately oneminute, if the passenger's front airbag
is activated.


Operating fault

If this warning lamp flashes in the
instrument panel and/or in the seat belt and
passenger's front airbag warning lamps
display, 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.
If even one of the two airbag warning lamps comes on continuously, do notinstall a child seat on the front passenger seat.
Have the system checked by a CITROËN dealer or a qualified workshop.


If this warning lamp comes on in theinstrument panel, accompanied by an
audible warning and the display of amessage, contact a CITROËN dealer or a qualified
workshop to have the system checked. The airbags mayno longer be deployed in the event of a serious impact.

Lateral airbags
System which protects the driver and frontpassenger in the event of a serious side impact
in order to limit the risk of injury to the chest,
between the hip and the shoulder.
Each lateral airba
g is fitted in the seat backrest frame, door side.

Deployment
Impact detection zones
A.Front impact zone.
B.Side impact zone. The lateral airba
gs are deployed unilaterally in
the event of a serious side impact applied to all
or par t of the side impact zone
B , perpendicular
to the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The lateral airbag inflates between the hip and
shoulder of the front occupant of the vehicle
and the corresponding door trim panel.
