System Outline
∗ The SRS airbag are provided for the driver and front passenger. The SRS airbags have been designed to help reducing
the shocks to the heads and chests of the driver and front passenger in the event of a severe frontal impact collision as
supplements to the seat belts.
This system is a 3–sensor type airbag system to detect the impact during a front collision using the airbag sensor
assembly center and airbag sensor (Front LH, RH), and to make the airbag system and pretensioner (LH, RH) operate as
well.
∗ In this system, a front side collision is detected by the side airbag sensor (LH, RH) in order to simultaneously deploy the
side and curtain shield airbags. A rear side collision is detected by the airbag sensor (Rear LH, RH) in order to deploy only
the curtain shield airbag.
∗ Dual–stage SRS airbags system, that controls the airbag inflating output optimum by judging the extent of impact and seat
position (Driver seat), has been used for the driver and front passenger airbags.
∗ In accordance with the adoption of the dual–stage SRS airbag system, a seat position sensor has been established for the
driver seat.
∗ This system has adopted a fuel cut control that stops the fuel pump when the airbag is deployed.
∗ The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
∗ The airbag stored inside the passenger's instrument panel is instantaneously expanded to soften the shock to the front
passenger.
∗ Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.
∗ The curtain shield airbag can ease an impact on the head of the front and rear passengers and reduce risks of injury.
∗ In a head–on crash, the driver moves forward and may strike his/her lower limbs against the instrument panel, etc. The
knee airbag is equipped to protect the lower limbs of the driver in head–on crashes.
∗ The pretensioners make sure of the seat belt restrainability.
