SRS

∗

The system reaches an ignition judgment to deploy the following device based on the signals received from the front
airbag sensor and deceleration sensor.
– Driver Airbag
– Front Passenger Airbag
– Seat Belt Pretensioner

∗

The system reaches an ignition judgment to deploy the following device based on the signals received from the side
airbag sensors.
– Side Airbags
– Curtain Shield Airbags

∗

The dual–stage SRS airbag system has been used for the driver and front passenger airbags. This system controls the
optimal airbag inflation by judging the extent of impact, seat position (driver seat), whether or not the seat belt is fastened
(driver seat) and information from the front passenger occupant classification system.

∗

The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult or
child (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat belt
is buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, and
front passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through the
use of the AIRBAG ON/OFF indicator lights.

∗

A Roll Sensing Curtain Shield Airbag system has been adopted in order to deploy the curtain shield airbags and the
pretensioners, in the event that the vehicle rolls over.

∗

A Roll Sensing Curtain Shield Airbag cutoff SW is provided near the driver side to enable the driver to disable this system.

∗

The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump when the
airbag is deployed.

∗

The airbag sensor assembly transmits a signal to the body ECU in order to release the door lock when the airbag is
deployed.
