Deployment of Emergency Tensioning

Devices and air bags

Important safety notes

WARNING

The air bag parts are hot after an air bag has

been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a

deployed air bag replaced at a qualified spe-

cialist workshop as soon as possible.

WARNING

A deployed air bag no longer offers any pro-

tection and cannot provide the intended pro-

tection in an accident. There is an increased

risk of injury.
Have the vehicle towed to a qualified special-

ist workshop in order to have a deployed air

bag replaced.

It is important for your safety and that of your

passenger to have deployed air bags replaced

and to have any malfunctioning air bags

repaired. This will help to make sure the air

bags continue to perform their protective

function for the vehicle occupants in the

event of a crash.

WARNING

Pyrotechnic Emergency Tensioning Devices

that have been deployed are no longer opera-

tional and are unable to perform their inten-

ded protective function. This poses an

increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-

sioning Devices which have been triggered

immediately replaced at a qualified specialist

workshop.

An electric motor is used by PRE-SAFE

trigger the tightening of the seat belt in haz-

ardous situations. This procedure is reversi-

ble.
If the Emergency Tensioning Devices or air

bags are deployed, you will hear a bang and a

small amount of powder may also be

released. The 6 restraint system warning

lamp will light up.
Only in rare cases will the bang affect your

hearing. The powder released is generally not

hazardous to health, it could however cause

short-term breathing difficulties in people

with asthma or other respiratory problems. In

order to prevent breathing difficulties, you

should leave the vehicle as soon as it is safe to

do so, or open the window.
Air bags and pyrotechnic seat belt tensioners

contain perchlorate material, which may

require special handling or environmental

protection measures. Check with your local

government’s disposal guidelines. California

Method of operation

During the first stage of a collision, the

restraint system control unit evaluates impor-

tant physical data relating to vehicle deceler-

ation or acceleration, such as:

Duration

Direction

Intensity

Based on the evaluation of this data, the

restraint system control unit triggers the belt

tensioners in the event of a frontal or rear

collision.
If the restraint system control unit detects a

high accident severity, additional compo-

nents of the restraint system are activated

independently of one another in certain fron-

tal collision situations:

Front air bags as well as driver's and front-

passenger kneebag

Depending on the person occupying the front-

passenger seat, the front-passenger air bag is

activated or deactivated. The front-passenger

front air bag can only be deployed in an acci-

dent if the PASSENGER AIR BAG OFF indica-

tor lamp is off. Observe the information on the
