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]).
Vehicles with ERA-GLONASS/EVAK: Both SRS curtain shield airbags will deploy in
the event of vehicle rollover.
All SRS side and curtain shield airbags will deploy in the event of a severe frontal colli-
sion.
Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags, SRS side and curtain shield airbags may also deploy if a serious
impact occurs to the underside of your vehicle. Some examples are shown in the illustra-
tion.
Hitting a curb, edge of pavement or hard sur-
face
Falling into or jumping over a deep hole
Landing hard or falling
Vehicles with ERA-GLONASS/EVAK: The SRS curtain shield airbags may also deploy
under the situations shown in the illustration.
The angle of vehicle tip-up is marginal
The vehicle skids and hits a curb stone
