1-1. For safe use
If the SRS airbags deploy (inflate)
■
Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
●
extremely high speed deployment (inflation) by hot gases.
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 will attempt to speak with the occupants to ascertain the
level of emergency and assistance required. If the occupants are unable to communi-
cate, the agent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. (P. 326)
SRS airbag deployment conditions (SRS front airbags)
■
The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
●
old 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 in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move
or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle "underrides", or goes under, the bed of a truck
Depending on the type of collision, it is possible that only the seat belt pretensioners will
●
activate.
The SRS front airbags for the front passenger will not activate if there is no passenger
●
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the seat is unoccupied. (P. 46)
SRS airbag deployment conditions (SRS side and curtain shield airbags)
■
The SRS side and curtain shield airbags will deploy in the event of an impact that
●
exceeds the set threshold level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 - 18 mph [20 - 30 km/h]).
The SRS curtain shield airbags will deploy in the event of vehicle rollover.
●
The SRS side and curtain shield airbags may also deploy in the event of a severe frontal
●
collision.
