For safety and security
■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, the glove box, parts of the front and rear pillars, and roof side rails may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Lexus Enform 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 emergency
call to the response center, notifying them of the vehicle’s location (without needing
to push the “SOS” button) and an agent wi ll 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. 3 6 8 )
