Depending on the vehicle, they may comprise:

  • seat belt inertia reel pretensioners;
  • chest force limiters;
  • airbags driver and passenger front.

These systems are designed to act independently or together when the vehicle is subjected to a frontal impact.

Depending on the severity of the impact, the system can cause:

  • blocking of the seat belt;
  • the seat belt inertia reel pretensioner which is triggered to correct seat belt slack;
  • the airbag and force limiter.

Load limiter

Above a certain severity of impact, this mechanism is used to limit the force of the belt against the body so that it is at an acceptable level.

Pretensioners

11010_XJI_028_1_image.jpeg

The pretensioners hold the seat belt against the body, holding the occupant more securely against the seat, thus increasing the seat belt's efficiency.

In the event of a severe frontal impact and if the ignition is switched on, the system may engage the following depending on the force of the impact:

  • the seat belt inertia reel pretensioner 1 which instantly retracts the seat belt.
warning
  • Have the entire restraint system checked following an accident.
  • No operation whatsoever is permitted on any part of the system (airbag, electronic units, wiring) and the system components must not be reused on any other vehicle, even if identical.
  • To avoid premature triggering of the system which may cause injury, only qualified Network personnel are authorised to work on the methods of restraint in addition to the front seat belt.
  • The electrical trigger system may only be tested by a specially trained technician using special equipment.
  • When the vehicle is scrapped, contact an approved dealer for disposal of the gas generators for the pretensioners and airbags.

driver and passenger front Airbags

Fitted to the driver and passenger sides.

The presence of this equipment is indicated by the word "Airbag" on the steering wheel, dashboard (in the area of the airbag2) and, depending on the vehicle, a label on the lower section of the windscreen.

Each airbag system consists of:

  • an airbag and gas generator are fitted on the steering wheel for the driver and on the dashboard for the passenger;
  • an electronic unit for monitoring the system controlling the gas generator electrical trigger;
  • a single warning light 2_ALL_094_1_pictogramme.png on the instrument panel;
  • remote sensors (depending on the vehicle).
warning

The airbag system uses pyrotechnic principles. This explains why, when the airbag inflates, it will generate heat, produce smoke (this does not mean that a fire is about to start) and make a banging noise. In a situation where an airbag is required, it will inflate immediately and this may cause some minor, superficial grazing to the skin or other problems.

Operation

This system is only operational when the ignition is switched on.

In the event of a severe frontal impact, the airbag(s) inflate rapidly, cushioning the impact of the driver's head and chest against the steering wheel and of the front passenger against the dashboard. They then deflate immediately so that the passengers are not in any way hindered when leaving the vehicle.

Operating faults

2_ALL_094_1_pictogramme.png This warning light comes on when the engine is started and then goes out after approximately three seconds.

If it does not come on when the ignition is switched on or if it stays on, there is a fault in the system.

Contact your approved Dealer as soon as possible;

Your protection will be reduced until this fault is rectified.

The following cases trigger the pretensioners or airbags.

In a frontal impact against a rigid (non-deformable) surface at an impact speed equal to or greater than 16 mph (25 km/h).

11010_XJI_031_1_image.jpeg

In a frontal impact with another vehicle of an equivalent or higher category, with an impact area equal to or greater than 40%, where the speed of both vehicles is equal to or greater than 25 mph (40 km/h).

In a side impact with another vehicle of an equivalent or higher category, at an impact speed equal to or greater than 31 mph (50 km/h).

11010_XJI_033_1_image.jpeg

The pretensioners or airbags may be triggered by:

  • an impact underneath the vehicle (e.g. pavement kerb);
  • potholes;
  • a drop or hard landing;
  • stones;
  • ...

The pretensioners or airbags may not be triggered by:

  • a rear impact, however severe;
  • the vehicle overturning;
  • ...

11010_XJI_035_1_image.jpeg

  • side impact at the front or rear of the vehicle;
  • frontal impact, underneath the tail of a lorry;
  • frontal impact against an obstacle with a sharp angle;
  • ...

Warnings

All of the following warnings are intended to ensure that the airbag is not obstructed in any way when it is inflated and also to prevent the risk of serious injury caused by items which may be projected when it inflates.

warning

Warnings in relation to the driver's airbag

  • Do not modify the steering wheel or the boss.
  • Do not cover the steering wheel boss under any circumstances.
  • Do not attach any objects (badge, logo, watch, telephone cradle, etc.) to the steering wheel boss.
  • The steering wheel must not be removed (except by qualified personnel from our Network).
  • Do not sit too close to the steering wheel: sit with your arms slightly bent (see "Adjusting your driving position" Seat belts). This will allow sufficient space for the airbag to deploy correctly and be fully effective.

Warnings in relation to the passenger airbag

  • Do not attach or glue any objects (badge, logo, clock, telephone holder, etc.) to the dashboard on or near the airbag.
  • Do not place anything between the dashboard and the passenger (animal, umbrella, walking stick, parcels, etc.).
  • The passenger must not put his or her feet on the dashboard or seat as there is a risk that serious injuries may be sustained. As a general rule, parts of the body should be kept away from the dashboard (knees, hands, head, etc.).
  • the devices in addition to the front passenger seat belt should be reactivated as soon as a child seat is removed, to ensure the protection of the passenger in the event of an impact.

A REAR-FACING CHILD SEAT MUST NOT BE FITTED TO THE FRONT PASSENGER SEAT UNLESS THE ADDITIONAL RESTRAINT SYSTEMS ARE NOT DEACTIVATED Child safety.
