METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS (1/4)

Depending on the vehicle, they are

composed of:

– seat belt inertia reel pretension-

ers;

– Have the entire restraint

system checked following

an accident.

– No operation whatso-

ever is permitted on any part of

the system (pretensioners, air

bags, computers, wiring) and the

system components must not

be reused on any other vehicle,

even if identical.

– lap belt pretensioners;

– chest-level load limiter;

– air bags for driver and front pas-

senger.

These systems are designed to act in-

dependently or together when the vehi-

cle is subjected to a frontal impact.

– To avoid incorrect triggering of

the system which may cause

injury, only qualified personnel

from an approved Dealer may

work on the pretensioner and air

bag system.

Depending on the severity of the

impact, the system can trigger:

– seat belt locking;

Pretensioners

– the seat belt inertia reel pretensioner

(which engages to correct seat belt

slack);

The pretensioners hold the seat belt

against the body, holding the occupant

more securely against the seat, thus in-

creasing the seat belt’s efficiency.

– The electric trigger system may

only be tested by a specially

trained technician using special

equipment.

– the low volume front air bag;

– the lap belt pretensioners to hold the

occupant in his seat;

In the event of a severe frontal impact

and if the ignition is switched on, the

system may engage the following de-

pending on the force of the impact:

– When the vehicle is scrapped,

contact an approved Dealer for

disposal of the pretensioner and

air bag gas generators.

– the large volume front air bag.

– the seat belt inertia reel preten-

sioner 1 which instantly retracts the

seat belt;

– the lap pretensioner 2 on the front

seats.

Load limiter

Air bags for driver and front

passenger

Fitted to the driver and passenger side.

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.

The presence of this equipment is in-

dicated by the word “Air bag” on the

steering wheel and dashboard (air bag

zone A) and, depending on the vehicle,

a symbol on the lower section of the

windscreen.

Each air bag system consists of:

– an air bag and gas generator fitted

on the steering wheel for the driver

and in the dashboard for the front

passenger;

– an electronic unit for system monitor-

ing which controls the gas generator

electrical trigger system;

– remote sensors;

The air bag system uses

pyrotechnic principles. This

explains why, when the air

– a single warning light

instrument panel.

on the

bag inflates, it will gener-

ate heat, produce smoke (this does

not mean that a fire is about to start)

and make a noise upon detonation.

In a situation where an air bag is

required, it will inflate immediately

and this may cause some minor, su-

perficial grazing to the skin or other

problems.

Operation

This system is only operational when

the ignition is switched on.

Special feature of the front air

bag

After a violent impact, it has two deploy-

ment volumes and integrates a ventila-

tion system:

In a severe frontal impact, the air bags

inflate rapidly, cushioning the impact

of the driver’s head and chest against

the steering wheel and of the front pas-

senger against the dashboard. The air

bags then deflate immediately so that

the passengers are not in any way hin-

dered from leaving the vehicle.

– low volume air bag, this is the first

stage of operation;

– large volume air bag, the air bag

seams rip so that a larger volume of

gas is released into the bag (for the

most severe impacts).

All of the warnings below are given so that the air bag is not obstructed in any way when it is inflated and also to prevent

the risk of serious injuries caused by items which may be dislodged when the air bag inflates.

Warnings concerning the driver’s air bag

– Do not modify the steering wheel or the steering wheel boss.

– Do not cover the steering wheel boss under any circumstances.

– Do not attach any objects (badge, logo, clock, telephone holder, 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 when driving: Sit with your arms slightly bent (see the information on “Adjusting

your driving position” in Section 1). This will allow sufficient space for the air bag to deploy correctly and to be fully effective.

Warnings concerning the passenger air bag

– Do not attach or glue any objects (badge, logo, clock, telephone holder, etc.) to the dashboard on or near the air bag.

– Do not place anything between the dashboard and the passenger (pet, 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.

In general, 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, I.E. THE PASSENGER AIR BAG, ARE DEACTIVATED.

(refer to the information on “Child safety: deactivating/activating the front passenger air bag” in Section 1)
