■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, and 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.622)

CAUTION
■SRS airbag precautions
● Do not attach anything to or lean any-
thing against areas such as the dash-
board or steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when SRS driver, front passenger and
knee airbags deploy.
● Do not attach anything to areas such as
the door, windshield glass, side door
glass, front or side pillars, roof side rail
or assist grip.
● Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and
may cause death or serious injury,
should the SRS curtain shield airbag
deploy.
● Vehicles without a smart key system:
Do not attach any heavy, sharp or hard
objects such as keys and accessories
to the key. The objects may restrict the
SRS knee airbag inflation or be thrust
into the driver’s seat area by the force
of the deploying airbag, thus causing a
danger.
