2012 Citroen DS4 Air con

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.

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.

189Safety
Curtain airbags
System which protects the driver andpassengers (with the exception of the rear centre passenger) in the event of a serious side
impact in order to limit the risk of injury to theside of the head.
Each curtain airbag is built into the pillars andthe upper passenger compartment area.

Deployment

The cur tain airbag is deployed at the same
time as the corresponding lateral airbag 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 cur tain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Operating fault
In the event of a minor impact or bump on the side of the vehicle or if the vehicle rolls over, the airbag may not be deployed.
In the event of a rear or front collision, the airbag is not deployed.
I
f this warning lamp comes on in theinstrument panel, accompanied by
an audible signal and a message in
the 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.

For the airbags to be fully effective, observe the following safety rules:
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre par t of the wheel.
Passengers must not place their feet on thedashboard.
If possible, do not smoke as deployment of the airbags can cause burns or the risk of injury from a cigarette or pipe.
Never remove or pierce the steering wheel or hit it violently.



Lateral airbags

Use only approved covers on the seats,compatible with the deployment the lateral airbags. For information on the range of seat covers suitable for your vehicle, you cancontact a CITROËN dealer (see "Practicalinformation - § Accessories").
Do not fix or attach anything to the seat backs (clothing...). This could cause injury to the chest or arms if the lateral airbag isdeployed.
Do not sit with the upper par t of the body any nearer to the door than necessary.


Curtain airbags

Do not fix or attach anything to the roof. This could cause injury to the head if thecurtain airbag is deployed.
If fitted on your vehicle, do not remove the grab handles installed on the roof, they play a par t in securing the cur tain airbags.


Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupantsand the airbags (a child, pet, object...). This could hamper the operation of the airbags or injure the occupants. After an accident or if the vehicle has beenstolen or broken into, have the airbagsystems checked. All work on the airbag system must be carriedout by a CITROËN dealer or a qualified workshop.
Even if all of the precautions mentioned are obser ved, a risk of injury or of minor burns to the head, chest or arms when an airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few milliseconds) then deflates within the sametime discharging the hot gas via openings provided for this purpose.
