SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The NSX includes a driver's side Airbag, located in the steering wheel hub, as part of a Supplemental Restraint
System (SRS). Information necessary to safely service the SRS is included in this Service Manual. Items marked
will require special cautions and tools and should therefore be done by an authorized Acura dealer.
l To avoid rendering the SRS inoperative, which can lead to personal injury or death in the event of a severe fron-
tal collision, all maintenance must be performed by an authorized Acura dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused
l
by unintentional activation of the Airbag.
All SRS selectrical wiring harnesses are covered with yellow outer insulation and related components are locat-
l
ed in the steering column, center console, dash, and dashboard lower panel. Do not use electrical test equip-
ment on these circuits.
