SUPPLEMENTAL RESTRAINT SYSTEM (SRS}
This model has an SRS which includes a driver's airbag in the steering wheel hub, a passenger's airbag in the dashboard
above the glove box ('97,00 models). and seat belt tensioners in the seat belt retractors ('98 - 00 models). Information
necessary to safely service the SRS is included in this Service Manual. ltems marked with an asterisk (*) on the contents
page include. or are located near, SRS components. Servicing, disassembling or replacing these items will require special
precautions and tools, and should only be done by an authorized Honda dealer.
@. To avoid rendering the SRS inoperative, which could lead to personal iniury or death in the event of 8 severe frontal
collision, all SRS service work must be performed by an authotized Honda dealer.
lmproper service procedures, including incorrect removal and installation of the SRS, could lead to personal iniury
caused by unintentional deployment of the airbags ('97 - 00 models), and seat belt tensioners 138 - 00 models).
Do not bump the SRS unit. Otherwise, the system may fail in case of a collision, or the airbags may deploy when the
ignition switch is ON {lll.
SRS eleqtrical wiring harnesses are identified by yellow color coding. Related components are located in the steering
column, front console, dashboard, dashboard lower panel, and in the dashboard above the glove box. Do not use elec-
tricaltest equipment on thes€ cilcuils.
