SRSComponents
Airbags
The SRSis a safetydevicewhich, when used with the seat belt, is designedto help protectthe driver and front
passenger a frontal impact exceedinga certainset limit. The system consistsofthe SRS unit, includingsafing
in
sensorand impactsensor(A),the cable reel (B),the driver's airbag(C),the front passenger,s airbag (D).seat belt
tensioners(l),seat belt buckletensioners(J), and front impactsensors(K).
Sincethe driver'sand front passenger's airbagsusethe same sensors,both normally inflateat the same ttme.
However,it is possiblefor only one airbagto inflate.This can occurwhen the severityof a collision is at the margin,or
threshold,that determineswhether or not the airbagswill deploy.In such cases, the seat belt will provide sufficient
protection,and the supplemental protectionofferedby the airbagwould be mininal.
Side Airbags
The side airbags(E)are in eachfront seat-back. They help protectthe upper torso of the driver or front seat passenger
during a moderateto severeside impact.Side impact sensors(F) in each door sill and in the SRS unit detectsuch an
impactand instantlyinflatethe driver'sor the passenger's side airbag.Only one side airbagwill deploy during a side
impacl. lf the impact is on the passenger's
side,the passenger's side airbagwill deploy even if there is no passenger.
Seat Belt and Seat Belt Buckle Tensioners
The seat belt and seat belt buckletensionersare linkedwith the SRSairbagsto further increase the effectiveness
of
the seat belt. ln a front-endcollision,the tensionersinstantlyretractthe belt and bucklefirmly to securethe occupants
in their seats.
OPDS
The side airbagsystemalso includesan occupantpositiondetectionsystem (OpDS). This systemconsistsof sensors

side airbag is disabled, the side airbagcutoff indicatoron the instrumentpanel alertsthe driver that the passenger's
side airbagwill not deploy in a side impact.When the object is removed,or the passenger sits upright,the side airbag
cutoff indicatorwill go off after a few seconds, alertingthe driver that the passenger's side airbagwill deploy in a side
