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 limiters;

– anti-submarining air bags;

– 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:

pretensioners

– seat belt locking;

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 seat belt inertia reel pretensioner

(which engages to correct seat belt

slack);

– the low volume front air bag;

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 lap seat belt pretensioners to

hold the occupant in his seat;

– the large volume front air bag.

– seat belt inertia reel pretensioner 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.

Depending on the vehicle, the pres-

ence of this equipment is indicated

by the word “Airbag” on the steering

wheel, dashboard (air bag zone A) and

a symbol on the lower section of the

windscreen.

A

Anti-submarining air bag

Located on each of the front seats, it

deploys in order to prevent the occu-

pant from sliding under the seat belt.

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 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.

– small 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).

1.27

mETHOds Of REsTRAINT IN AddITION TO THE fRONT sEAT BELTs (4/4)

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).

– When driving, do not sit too close to the steering wheel. 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 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 occur. 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.

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

Warnings concerning the anti-submarining air bag

Do not let a child under the age of 12 sit in this seat. When triggered, the anti-submarining air bag may project objects left on

the seat base with a great deal of force.

force 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.

– Have the entire restraint

system checked following

an accident.

– No operation whatsoever

is permitted on any part of the

system (air bags, electronic con-

trol units, wiring) and the system

components must not be reused

on any other vehicle, even if iden-

tical.

– Only qualified personnel from

our Network may work on the air

bags; otherwise the system may

trigger accidentally and cause

injury.

1.29

sIdE pROTEcTION dEvIcEs

side air bags

These air bags are fitted to the front

seats and are activated at the sides of

the seats (door side) to protect the oc-

cupants in the event of a severe side

impact.

curtain air bags

These are air bags fitted along the sides

of the vehicle in the ceiling which trigger

along the front and rear side windows

to protect the passengers in case of a

severe side impact.

Warnings concerning the side air bag

– fitting seat covers: seats equipped with an air bag require covers

specifically designed for your vehicle. Contact an approved Dealer to find

out if these covers are available. The use of any covers other than those

designed for your vehicle (and including those designed for another vehicle)

may affect the operation of the air bags and reduce your protection.

– Do not place any accessories, objects or even pets between the seatback, the

door and the internal fittings. Do not cover the seatback with any items such as

clothes or accessories. This may prevent the air bag from operating correctly

or cause injury when the air bag is deployed.

– No work or modification whatsoever may be carried out on the seat or internal

fittings, except by qualified personnel from an approved dealer.

– The area between the rear bench seatback and the trim is the area of air bag

operation: no objects must be placed here.

AddITIONAL mETHOds Of REsTRAINT

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.

The air bag is designed to complement the action of the seat belt. Both

the air bags and seat belts are integral parts of the same protection

system. It is therefore essential to wear seat belts at all times. If seat belts

are not worn, the occupants are exposed to the risk of serious injury in

the event of an accident. It may also increase the risk of minor superficial injuries

occurring when the air bag is deployed, although such minor injuries are always

possible with air bags.

If the vehicle should overturn or suffer a rear impact, however severe, the pre-

tensioners and air bags are not always triggered. Shocks to the underbody of the

vehicle, e.g. from pavements, potholes or stones, can all trigger these systems.

– No work or modification whatsoever may be carried out on any part of the air

bag system (air bags, pretensioners, computer, wiring harness, etc.), except

by qualified personnel from an approved dealer.

Operating faults

Warning light 1 will light up on the in-

strument panel when the ignition is

switched on and then go out after a few

seconds.

– To ensure that the system is in good working order and to avoid accidental trig-

gering of the system which may cause injury, only qualified Network personnel

may work on the air bag system.

– As a safety precaution, have the air bag system checked if your vehicle has

been involved in an accident, or is stolen or broken into.

If it does not come on when the ignition

is switched on, or if it comes on when

the engine is running, there is a fault

with the system (air bags, pretension-

ers, etc.) in the front and/or rear seats.

– When selling or lending the vehicle, inform the user of these points and hand

over this driver’s handbook with the vehicle.

– When scrapping your vehicle, contact your approved dealer for disposal of the

gas generator(s).

Contact your approved dealer as soon

as possible. Your protection will be re-

duced until this fault is rectified.
