■

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, center 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 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 emer-

gency and helps to dispatch the necessary emergency services. (

SRS airbag deployment conditions (SRS front airbags)

●

The SRS front airbag will deploy in the event of an impact that exceeds the set

threshold level (the level of force corresponding to an approximately 12 - 18 mph

[20 - 30 km/h] frontal collision with a fixed wall that does not move or deform).

However, this threshold velocity will be considerably higher if the vehicle strikes

an object, such as a parked vehicle or sign pole, which can move or deform on

impact, or if the vehicle is involved in an underride collision (e.g. a collision in

which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).

●

It is possible that in some collisions where the forward deceleration of the vehi-

cle is very close to the designed threshold level, the SRS front airbags and the

seat belt pretensioners may not activate together.

●

The SRS front passenger airbag will not activate if there is no passenger sitting

in the front passenger seat. However, the SRS front passenger airbag may

deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is

unoccupied. (
