183Safety
Deactivation
Only the passenger's front airbag can be deactivated:  with the ignition off , inser t the key in the n offpassenger airbag deactivation switch,  turn it to the "OFF" position,  then, remove the key keeping the switch in the new position.
According to version, this warning lamp comes on either in the instrument panel or in the seat belt and passenger's front airbag warning lamps display when the ignition is on and until the airbag is reactivated.
To assure the safety of your child, the passenger's front airbag must be deactivated when you install a "rear facing" child seat on the front
passenger seat. Other wise, the child would risk being seriously 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 ignition on, this warning
lamp comes on in the seat belt and passenger's front airbag warning lamps display for approximately one minute, if the passenger's front airbag is activated.
Operating fault
If this warning lamp flashes, 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 not install 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 the instrument panel, accompanied by an audible warning 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 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.
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 (see "Practical information - § 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 is deployed. 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 the cur tain airbag is deployed.
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 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 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 same time discharging the hot gas via openings provided for this purpose.

181Safety
Airbags
System designed to maximise the safety of the occupants (with the exception of the rear centre passenger) in the event of violent collisions. It supplements the action of the force-limiting seat belts (with the exception of the rear centre 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 protect 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 cer 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 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.
Impact detection zones
A. Front impact zone. B. Side impact zone.
Deployment of the airbag(s) is
accompanied by a slight emission of harmless smoke and a noise, due to the activation of the pyrotechnic car tridge 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 shor t time.

Lateral airbags
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.
Deployment Impact detection zones
A. Front impact zone. B. Side impact zone.
The lateral airbags 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.

185Safety
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 cur tain airbag is built into the pillars and the upper passenger compar tment 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.
If this warning lamp comes on in the instrument 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.

Electric parking brake
The electric parking brake combines2 operational modes: - Automatic Application/Release Application is automatic when the engine stops, release is automatic on use of the accelerator (activated by default), - Manual Application/Release The parking brake can be applied/released manually by pulling control lever A .
Do not place any object (packet of cigarettes, telephone...) between the gear lever and the electric parking brake control lever.
It is recommended that you do not apply the parking brake in very cold conditions (ice) and during towing (breakdown, caravan...). Deactivate the automatic functions and release the parking brake manually.
If this warning lamp comes on in the instrument panel, the automatic mode is deactivated.
Programming the mode
Depending on the country of sale of the vehicle,
the automatic application when the engine is switched off and the automatic release when you press the accelerator can be deactivated.
Activation/deactivation is done using the vehicle configuration menu; refer to the section covering the configuration of your vehicle's systems.
The parking brake is then applied and released manually. When the driver's door is opened, there is an audible signal and a message is displayed if the brake is not applied.

191Driving
With the ignition on or the engine running, to release the parking brake, press on the brake pedal or the accelerator, pull then release control A .
Manual release
Before leaving the vehicle, check that parking brake warning lamp in the instrument panel is on fixed, not flashing.
Manual application
With the vehicle stationary, to apply the parking brake whether the engine is running or off, pullcontrol lever A .
The application of the parking brake is confirmed by:
- illumination of the braking warning lamp and of the P warning lamp in the control lever A ,
- display of the message "Handbrake on".
When the driver’s door is opened with the engine running, a message is displayed accompanied by an audible signal if the parking brake has not been applied.
The full application of the parking brake is confirmed by:
- the braking warning lamp and the P warning lamp in the control lever A going off,
- display of the message "Handbrake off ".
If you pull control lever A without pressing the brake pedal, the parking brake will not be released and a warning lamp will come on in the instrument panel.
Maximum application
If necessary, you can make a maximum application of the parking brake. This is obtained by means of a long pull on the control lever A , until you see the message "Handbrake on maximum" and a beep is heard. Maximum application is essential: - in the case of a vehicle towing a caravan or a trailer, if the automatic functions are activated but you are applying the parking brake manually, - when the gradient you are parked on may vary (e.g. on a ferry, on a lorry, during towing),
In the case of towing, a loaded vehicle or parking on a gradient, make a maximum application of the parking brake then turn the front wheels towards the pavement and engage a gear when you park. After a maximum application, the release time will be longer.
