■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 front seats, parts of the front and rear pillars, and roof side
rail, may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● For Safety Connect subscribers, if the SRS airbags deploy or in the event
of a severe rear-end collision, the system is designed to send an emer-
gency 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 assis-
tance 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.639)
