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.
●
Vehicles with ERA-GLONASS: If the SRS airbags deploy, the system is designed to
●
send an emergency call
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 emergency and helps to dispatch the necessary emergency services.
(P. 384)
*
: In some cases, the call cannot be made. (P. 386)
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 20 - 30 km/h [12 - 18
mph] 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.
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 1500 kg [3300 lb.] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 20 - 30 km/h [12 - 18 mph]).
The SRS side and curtain shield airbags may also deploy in the event of a severe frontal
●
collision.
