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, parts of the front and rear pillars, and roof side rails may be hot for several min-
utes. The airbag itself may also be hot.
The windshield may crack.
●
All of the doors will be unlocked. (P. 160)
●
Fuel supply to the engine will be stopped. (P. 600)

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]).
Both SRS curtain shield airbags may also deploy in the event of a severe frontal colli-
●
sion.
