sensors in the airb ag c ontrol mod ule d etec t a c erta in p red etermined
amount of forc e d uring a frontal c ollision, the c on trol mod ule send s
sig nals to the airb ag mod ules instruc ting them to i nflate the SRS air-

d river ’s and p asseng er ’s SRS airb ag s. After the d ep loyment, the SRS
airb ag s immed iately start to d eflate so that the d r iver’s vision is not
ob struc ted . The time req uired from d etec ting imp ac t to the d eflating
SRS airb ag after d ep loyment is shorter than the b li nk of eye.
The front p asseng er ’s SRS airb ag d ep loys tog ether with d river ’s SRS
airb ag even when no one oc c up ies the front p asseng e r’s seat.
Althoug h it is hig hly unlikely that the SRS airb ag would ac tivate in a
non-ac c id ent situation, should it oc c ur, the SRS ai rb ag will d eflate
q uic kly, not ob sc uring vision and will not interfer e with the d river’s
ab ility to maintain c ontrol of the vehic le.
When the SRS airb ag d ep loys, a sud d en, fairly loud inflation noise will
