Airbag Assembly Disposal
Before scrapping any airbag(s) (including one in a wholecar to be scrappedl, the airbag must be deployed. t{ thecar is still within the warranty period, before you deplovthe ai.bag, the Acura District Service Manager must giveapproval and/or special instructions. Onlv after the air-ba9 has been deployed (as the result of vehicle collision,for example),it can be scrapped.lf the airbag(s) appear(s) intact (not deptoyed, treat it{them) with extreme caution.Follow this Drocedure:
Doploying the Airbag(sl: In-car
NOTE: lf an SRS car is to be entirely scrapped. itsairbag(s) should be deployed while still in the car. Theairbag(s) should not be considered as salvageablepan(sl and should never be installed in another car.
