Before performing pre-disposal deployment of any SRS part, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.
1. PRECAUTION
An airbag or pretensioner may be activated by static electricity. To prevent this, be sure to touch a metal surface with your bare hands to discharge static electricity before performing this procedure.
Do not perform this procedure indoors or on rough roads where safety cannot be ensured. Also, do not deploy SRS parts near residential areas.
If this procedure is performed indoors or on rough roads where safety cannot be ensured, unforeseen injuries may occur. Also, the deployment noise creates a nuisance to nearby residents.
When scrapping a vehicle equipped with an SRS or disposing of the lower No. 1 instrument panel airbag assembly, be sure to deploy the airbag first in accordance with the following procedure. If any abnormality occurs with the airbag deployment, contact the Service Department of the distributor.
