Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving on snow: intelligent traction control.
This system detects situations of difficult sur face 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. In extremely severe conditions (deep snow, mud, ...), when it proves impossible to move off, it may be useful to temporarily deactivate the ESP/ASR systems to allow the wheels to spin freely and so allow movement of the 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 warning 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 when braking.
When this warning lamp comes on, coupled with the STOP warning lamp, accompanied by an audible signal and a message, it indicates that there is a fault with the electronic brake force distribution (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 of snow tyres is strongly recommended on sur faces offering low levels of adhesion.

DSC/ASR
The DSC and ASR systems offer increased safety in normal driving, but they should not encourage the driver to take extra risks or drive at high speed. It is in conditions of reduced grip (rain, snow, ice) that the risk of loss of grip increases. It is therefore important for your safety to keep the DSC and ASR systems activated in all conditions, and particularly in difficult conditions.
The correct operation of these systems depends on observation of the manufacturer's recommendations regarding as much the wheels (tyres and
rims), braking and electronic components as the assembly and repair procedures used by CITROËN dealers. To benefit in full from the effectiveness of the DSC and ASR systems in wintry conditions, the vehicle must be fitted with four snow tyres, allowing the the vehicle to retain neutral behaviour on the road.
After an impact, have these systems checked by a CITROËN dealer or a qualified workshop.

1. Front and/or rear seat belts not fastened / unfastened warning lamp in the instrument panel. 2. Front left seat belt warning lamp. 3. Front right seat belt warning lamp. 4. Rear right seat belt warning lamp. 5. Rear centre seat belt warning lamp. 6. Rear left seat belt warning lamp.
Front seat belt warning lamps
On switching on the ignition, warning lamp 1 comes on in the instrument panel and the corresponding warning lamp 2 and/or 3 come(s) on in red in the passenger's seat belt and front airbag warning lamp display if the corresponding seat belt is not fastened or is unfastened.
Rear seat belt warning lamps
On switching on the ignition, the corresponding warning lamps 4 , 5 and 6 come on in red for about 30 seconds if a seat belt is not fastened.
Above 12 mph (20 km/h), the corresponding warning lamps 4 , 5 or 6 comes on in red, accompanied by an audible signal and a message in the instrument panel screen, when a rear passenger has unbuckled their seat belt.
* According to version and/or country of sale.

The driver must ensure that passengers use the seat belts correctly and that they are all restrained 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 is stowed automatically when not in use. Before and after use, ensure that the seat belt is reeled in correctly. The lower part of the strap must be positioned as low as possible on the pelvis. The upper part must be positioned in the hollow of the shoulder. The inertia reels are fitted with an automatic locking device which comes into operation in the 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 shorter 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 not twist, - be used to restrain only one person, - not bear any trace of cuts or fraying, - not be converted or modified to avoid affecting its performance. In accordance with current safety regulations, 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 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.
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 to the activation of the pyrotechnic cartridge incorporated in the system. In all cases, the airbag warning lamp comes on. Following an impact, have the seat belts system checked, and if necessary replaced, by a CITROËN dealer or a qualified workshop.

Airbags
System designed to maximise 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: - in 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, - in the case of a minor or rear impact or in certain roll-over conditions, the airbags will 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 the airbag(s) 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 the detonation may result in a slight loss of hearing for a short time.
Impact detection zones
A. Front impact zone. B. Side 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 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 thorax and head of the front occupant of the vehicle and the steering wheel, driver's side, and the dashboard, passenger's side to cushion their forward movement.
System 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 is fitted in the dashboard above the glove box.

207Safety
DS5-HYBRID_EN_CHAP07_SECURITE_ED02-2013
Lateral airbags
Deployment
The lateral airbags are deployed unilaterally in the event of a serious side impact applied to all or part 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.
System which protects the driver and front passenger 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 airbag is fitted in the seat backrest frame, door side.
Impact detection zones
A. Front impact zone. B. Side impact zone.
Curtain airbags
System which protects the driver and passengers (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 the side of the head. Each curtain airbag is built into the pillars and the upper passenger compartment area.
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 curtain airbag is not deployed.
Deployment
The curtain airbag is deployed at the same time as the corresponding lateral airbag in the event of a serious side impact applied to all or part 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 curtain airbag inflates between the front or rear occupant of the vehicle and the windows.
If this warning lamp comes on in the instrument panel, accompanied by an audible signal and a message in the instrument 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.
Operating fault

Sit in a normal upright position. Wear a correctly adjusted seat belt. Do not leave anything between the occupants and 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 been stolen or broken into, have the airbag systems checked. All work on the airbag system must be carried out by a CITROËN dealer or a qualified workshop. Even if all of the precautions mentioned are observed, 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 same time discharging the hot gas via openings provided for this purpose.
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 can contact a CITROËN dealer. Refer to the "Accessories" section. Do not fix or attach anything to the seat backs (clothing...). This could cause injury to the chest or arms if the lateral airbag is deployed. Do not sit with the upper part of the body any nearer to the door than necessary.
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre part of the wheel. Passengers must not place their feet on the dashboard. 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.
For the airbags to be fully effective, observe the following safety rules:
Curtain airbags
Do not fix or attach anything to the roof. This could cause injury to the head if the curtain airbag is deployed. If fitted on your vehicle, do not remove the grab handles installed on the roof, they play a part in securing the curtain airbags.
