Information 

Only ignite airbag units that are securely installed and in original condition in the vehicle. Allow airbag units to cool down under observation following ignition.

• Use only the ignition tool intended for this purpose. First remove all loose objects from the expansion area of the airbag. 
• Every ignition circuit for all airbag units and seat-belt pretensioners must be ignited individually. 
• Persons who may be affected must be informed of the resulting noise beforehand. 
• Wear ear protectors. 
• Keep a safe distance by utilizing the entire cable length of the ignition tool. Do not connect the voltage source until all other preparations are complete. 
• If ignition fails, wait for approx. 3 minutes before approaching the vehicle. 
• Carry out ignition only in suitable, open areas. 
• Do not allow ignited airbag units to come into contact with the skin.
