Your vehicle is equipped with “ADVANCED AIRBAGS” designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver’s seat position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, and parts of the front pillar and roof side rail, may be hot for
several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For vehicles with Safety Connect: For Safety Connect subscribers, if the SRS
airbags deploy or in the event of a severe collision, the system is designed to
send an emergency call to the response center, notifying them of the vehicle’s
location (without needing to push the “SOS” button) and an agent will attempt
to speak with the occupants to ascertain the level of emergency and assistance
required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency
services. (P. 4 3 3 )
