Airbag, Belt Tensioner and Battery Cut-Out Units, General Safety Precautions
Airbag, Belt Tensioner and Battery Cut-Out Units, General Safety Precautions
CAUTION!
• Pyrotechnic components always contain chemicals, which turn into an expanding gas when detonated. In some forms, when this gas is produce, it is stored under pressure.
• This gas is contained under high pressure and is stored in a pressurized gas container.
• An electric/mechanical igniter ignites the pyrotechnic components.
• Testing, removing, installing and repair work may only be performed by qualified personnel.
• There is no change interval for airbag units.
• Never test with a test light, volt meter or ohm meter.
• The pyrotechnic components may be check only when they are installed and with a Volkswagen approved vehicle diagnosis, testing and information system.
• When working on pyrotechnic components and on the Airbag control module, the battery ground cable must be disconnected when the ignition is switched on. Then cover the negative terminal.
• Wait for 10 seconds after disconnecting the battery.
• The ignition must be SWITCHED ON when connecting the battery. Nobody should be inside the vehicle with doing this. Exception: Vehicles with a battery inside the passenger compartment. Stay away from the airbags and the safety belts.
• Wash hands after touching ignited restraint system pyrotechnic components.
• Pyrotechnic components may not be opened nor repaired; always use new parts (risk of injury).
• Pyrotechnic components that have fallen onto a hard surface or show signs of damage must not be installed in vehicle.
• Before handling pyrotechnic components and restraint systems, for example, before connecting the connector, the person handling them must discharge static electricity Touching grounded metal parts, for example, touching the door latch, will discharge the static electricity.
• Pyrotechnic components should be installed immediately upon removal from shipping package.
• If the work must be stopped for awhile, put the pyrotechnic component back into its shipping package.
• Do not leave the pyrotechnic component out unattended.
• Do not use any grease or cleaning solutions on pyrotechnic components.
• Pyrotechnic components must not be exposed to temperatures over 212° F (100 °C), even for a short time.
Belt Tensioner, Special Instructions
CAUTION!
• The open end of the belt tensioner should never be pointed at anyone.
• Exercise extreme care when removing and installing a belt tensioner unit. Handling belt tensioner units improperly is very dangerous and could result in serious personal injury.
• When connecting belt tensioner, all mechanical parts including those in three-point seat belt, must be secured correctly. If it is not possible to connect the belt tensioner unit because there is not enough space, then roll the seat belt all the up. In this case there is no increase safety risk, if all other safety instructions are followed. This applies especially to the notes regarding disconnecting the battery and the static discharging of the technician before connecting the belt tensioner unit.
• Even after a crash it is possible that the belt tensioner did ignite, but the belt force limiter did NOT ignite. Treat these components as if they were not ignited!
