The wearing of seat belts is compulsory for all vehi-cle occupants. Inside the cabin, the seat belt is the most important protection for passengers.
The airbag is a protection in addi-tion to the seat belt. Its effective-ness requires the seat belt to be worn correctly.
Children under ten years of age should always be carried in the rear seats. See "Child safety".
The driver and passengers must adopt a normal, vertical sitting posi-tion that is compatible with deploy-ment of the airbags. See "Driving position".
Never attach anything to the stee-ring wheel central cover, to the sides of the front seats or to the vehicle pillars or roof (risk of injuries should the airbags deploy).
Hold the steering wheel in the "quar-ter-past-nine" position: do not hold it by the branches or rest your hands on its central cover.
Smoke as little as possible in the vehicle (risk of burns or injury should the airbag be deployed).
Do not leave any accessory or object on the dashboard or between your body and the airbag (risk of malfunction or personal injury).
Fit only seat covers that are approved by CITROËN.Fit only seat covers that are approved Fit only seat covers that are approved
Do not put your feet on the dash-board (risk of injury should the front passenger airbag deploy).
The airbags do not deploy in the case of a slight collision or an impact at the rear of the vehicle or in certain manoeuvring conditions.
The deployment of one or more air-bags is accompanied by a small release of unharmful smoke, as well as by a detonation that is caused by the activation of the pyrotechnic car-tridge integral to the system. This smoke is not toxic but may be an irritant to persons who are sensitive.
The noise of the detonation may affect hearing for a brief time.
Vacate the vehicle as soon as pos-sible after the accident (provided it is safe to do so). If this is not possible, open the windows or doors.
Even observing all the advised pre-cautions, the risk of injury or slight burning to the head, chest or arms during deployment of an airbag can-not be ruled out. In fact, infl ation of the airbag is virtually instantaneous (approx. 30 milliseconds); then it defl ates in the same time, emitting hot gases through holes provided for this purpose. This equipment works only once. It cannot operate to pro-vide further protection in the event of a second impact.
It is imperative to have the system overhauled in strict compliance with the manufacturer's specifi -cations.

AIRBAGS
Replacement of the pyro-technic systems associa-ted with the airbags
After the airbags have been deployed, the pyrotechnic sys-tems have to be changed in strict compliance with the manufac-turer's specifi cations.
Your vehicle may have:
A driver’s airbag located in the Asteering wheel, under the central cover.
A passenger's airbag in the dash-Aboard.
Two side airbags located in the backrests of the driver’s seat and front passenger’s seat (door side).Two curtain airbags located on the interior edges of the roof.The control unit for the airbags and sensors analyses any frontal and lateral impacts suffered in the colli-sion detection zones (see illustration p 91).

Area of frontal impact
Side airbags and curtain airbags
Deployment of these airbags requires a violent lateral impact applied on all or part of one of the lateral collision zones, coming in a horizontal plane from the side.
The role of the side airbag is to place itself between the occupant (driver or front passenger) and the door panel, thus limiting the risk of injuries to the chest.
Front airbags and knees airbags
For these airbags to deploy, it requires a violent frontal impact applied on all or part of the frontal impact zone (see illustration) from forward of the vehicle in a horizontal plane.
The airbag interposes itself between the vehicle's front occupant and the dashboard to cushion the person from being thrown forward. The air-bag thus limits the risk of trauma to the head and chest. For the driver, the knees airbag protects the knees.
The front passenger’s airbag can be deactivated. see "Passenger's air-bag deactivation".
Examples of impact detection zones
The role of the curtain airbag is to place itself between the front or rear occupant and the windows, thus limiting the risk of injuries to the head.
These airbags may not deploy if there is only a slight collision on the side of the vehicle, or if the vehicle rolls over. They will not deploy for a front or rear collision.

Any operation under the bonnet necessitates a number of safety pre-cautions.
Be particularly careful both before and during all checks under the bonnet:
Allow the engine to cool down.
Keep children away from the ve-hicle.
Make sure that you possess the necessary tools and expertise.
Bonnet
Before opening the bonnet, make sure that your hands and clothing are protected. Allow the engine to cool down.
Make sure that the bonnet is stable in the open position. Beware of gusts of wind that could cause the bonnet to fall and cause seriuous injuries.

Radiator
In normal usage, the coolant tempe-rature reaches or exceeds 100 °C. Never remove the cap of a radia-tor that is hot: there is danger from projection of scalding liquid and steam. See "Levels".
The antifreeze contained in the cool-ant lends it the following properties:
Protection against low tempera-tures (initial protection: -35 °C).
Anti-corrosion protection.
Resistance to high operating temperatures.See the Maintenance Guide.

This driving assistance device alerts you if you are wandering from your lane (continuous or dotted line marking on the road surface).
It is designed especially for use on motorways and dual carriageways, operating only at speeds above 80 km/h (approx. 50 mph).
The driver must still remain attentive and in complete control of the vehicle.
Operation
Provided you are travelling at over 80 km/h (approx. 50 mph), if you cross a lane marking, you are alerted by a vibration within the cushion of your seat:
- oriented to the right for crossing a lane marking to the right,
- oriented to the left for crossing a lane marking to the left.
The system does not alert you while your direction indicator is operating, nor for about 20 seconds after your direction indicator has stopped.
Activation/Deactivation
A press on control A activates the function, the warning lamp on the control lights up.
A second press on control A deacti-vates the function, the warning lamp on the control goes out.
Whenever you start the engine, the mode (activated/deactivated), selected when you last switched off the engine, is retained.
LANE DEPARTURE WARNING SYSTEMThe effectiveness of the system may be temporarily affected by conditions external to the vehicle:
• Detection of lanes made diffi cult by:
- Markings that are worn or erased.
- Insuffi cient contrast with the sur-face of the road.

The parking brake is applied, with the vehicle stationary, by pulling on the lever with a force that is proportionate to the steepness of the slope.
To facilitate the action on the lever, you are recommended to press the brake pedal at the same time.
In all circumstances, as a precautionary measure, engage fi rst gear. For vehicles equipped with an automatic gearbox, ensure that the parking position (P) is selected.
On steep slopes, turn the steering wheel towards the kerb.
To release the handbrake, press on the end of the lever, pull the lever up then lower it fully.
HANDBRAKE
Before leaving the vehicle, make sure that the parking brake is suffi -ciently applied to prevent the vehicle from moving if on a slope, or if acci-dentally or deliberately pushed.
As an additional precaution on steep slopes:Apply the parking brake.
Engage a gear.Turn the steering wheel towards the kerb (if there is one).
