Safety

The belt tensioners will not be triggered in the

event of minor collisions, if the vehicle over-

turns, or in accidents where no major forces

act on the vehicle.

WARNING

Improper use or repairs not carried out by

qualified mechanics increase the risk of se-

vere or fatal injuries. The belt tensioners

may fail to trigger or may trigger in the

wrong circumstances.

For the inflating airbags to achieve the best

protection, the seat belt must always be worn

properly and the correct sitting position must

be assumed.

observed when the vehicle or components

of the system are scrapped. Specialised

workshops are familiar with these regula-

tions, which are also available to you.

●

Any work on the belt tensioners and seat

belts, including the removal and refitting of

system parts in conjunction with other re-

pair work, must be performed by a special-

ised workshop only.

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 vehicle occupants are

wearing their seat belts correctly and have

adjusted the head restraints properly. There-

fore, it is most important to properly wear the

seat belts at all times, not only because this is

required by law in most countries, but also for

Maintenance and disposal of belt

tensioners

●

The belt tensioners will only provide pro-

tection for one accident and must be

changed if they have been activated.

The belt tensioners are components of the

seat belts that are installed in the seats of

your vehicle. If you work on the belt tension-

ers or remove and install parts of the system

when performing other repair work, the seat

belt may be damaged. The consequence

may be that, in the event of an accident, the

belt tensioners function incorrectly or may

not function at all.

belt.

The airbag inflates in a matter of seconds, so

if you are not properly seated when the air-

bag is triggered, you may sustain fatal inju-

ries. Therefore, it is essential that all vehicle

occupants assume a correct sitting position

while travelling.

So that the effectiveness of the seat belt ten-

sioner is not reduced and that removed parts

do not cause any injuries or environmental

pollution, regulations, which are known to the

specialised workshops, must be observed.

Always maintain the greatest possible dis-

tance between yourself and the front airbag.

This way, the front airbags can completely

deploy when triggered, providing their maxi-

mum protection.

front airbag.

The airbag system operation is monitored

electronically. The airbag control lamp will il-

luminate for a few seconds every time the ig-

nition is switched on (self-diagnosis).

The most important factors for triggering the

airbag are the type of accident, the angle of

impact and the vehicle speed.

●

To reduce the risk of injury from an inflat-

ing airbag, always wear the seat belt prop-

erly page 69.

●

Whether or not the airbags are triggered de-

pends primarily on the vehicle deceleration

rate resulting from the collision and detected

by the control unit. If the vehicle deceleration

occurring during the collision and measured

by the control unit remains below the speci-

fied reference values, the front, side and/or

curtain airbags will not be triggered. Take into

account that the visible damage in a vehicle

involved in an accident, no matter how seri-

ous, is not a determining factor for the air-

bags to have been triggered.

Safety instructions about

airbags

If the deceleration rate is below the prede-

fined reference value in the control unit the

airbags will not be triggered, even though the

accident may cause extensive damage to the

car.

Airbag activation

Front airbags

The airbags deploy extremely rapidly, within

thousandths of a second, to provide addition-

al protection in the event of an accident. A

fine dust may develop when the airbag de-

ploys. This is normal and it is not an indication

of fire in the vehicle.
