Front airbags

Description of front airbags

The airbag system is not a substitute for the seat belts.

The front airbag for the driver is located in the steering wheel ⇒ fig. 17 and

the airbag for the front passenger is located in the instrument panel

⇒ fig. 18. Airbags are identified by the word “AIRBAG”.

In conjunction with the seat belts, the front airbag system gives the front

occupants additional protection for the head and chest in the event of a

severe frontal collision ⇒ page 36, “Safety notes on the frontal airbag

system”.

In addition to their normal function of restraining the occupants, the seat

belts also hold the driver and front passenger in a position where the airbags

can provide maximum protection in a frontal collision.

The airbag system is not a substitute for seat belts, but it is an integral part

of the vehicle's overall passive safety system. Please bear in mind that the

airbag system can only work effectively when the occupants are wearing their

seat belts correctly and have adjusted the head restraints properly. Therefore,

it is most important to wear the seat belts at all times, not only because this

is required by law in most countries, but also for your safety ⇒ page 19,

“Brief Introduction”.

The main parts of the front airbag system are:

• an electronic control and monitoring system (control unit),

• the two front airbags (airbag with gas generator) for the driver and front

passenger,

• a warning lamp  in the dash panel insert ⇒ page 30.

The airbag system operation is monitored electronically. The airbag warning

lamp will light up for a few seconds every time the ignition is switched on

(self-diagnosis).

There is a fault in the system if the warning lamp 

• does not light up when the ignition is switched on ⇒ page 30,

• after the ignition is switched on, it turns off after 4 seconds,

• it turns off and then lights up again after the ignition is switched on,

• lights up or flashes while the car is moving.

The front airbag system will not be triggered if:

• the ignition is switched off,

• there is a minor frontal collision,

• there is a side collision,

• there is a rear-end collision,

• the vehicle turns over.

WARNING

• The seat belts and airbags can only provide maximum protection if the

occupants are seated correctly ⇒ page 10, “Proper sitting position for

occupants”.

• If a fault has occured in the airbag system, have the system checked

immediately by a qualified workshop. Otherwise, during a frontal collision

the system may fail to trigger, or not trigger correctly.

Operation of frontal airbags

Inflated airbags reduce the risk of head or chest injury.

The airbag system is designed so that the airbags for the driver and front

passenger are triggered in a severe frontal collision.

In certain types of accident the front, curtain and side airbags may be trig-

gered together.

When the system is triggered, the airbags fill with a propellant gas and

deploy in front of the driver and front passenger ⇒ fig. 19. The fully deployed

airbags cushion the forward movement of the front occupants and help to

reduce the risk of injury to the head and the upper part of the body.

The special design of the airbag allows the controlled escape of the propel-

lant gas when an occupant puts pressure on the bag. Thus, the head and

chest are surrounded and protected by the airbag. After the collision, the

airbag deflates sufficiently for the front occupants to see forward.

In order to provide the desired extra protection in an accident, the airbags

have to deploy extremely rapidly (within thousandth of a second). A fine dust

may develop when the airbag deploys. This is normal and it is not an indica-

tion of fire in the vehicle.

Airbag covers when the frontal airbags are triggered

The airbag covers fold out of the steering wheel and dash panel when the

driver and front passenger airbags deploy ⇒ fig. 20. The airbag covers

remain connected to the steering wheel or the dash panel.
