SRS airbag deployment  conditions (SRS side and curtain shield a irbags)
● The  SRS  side  and  curtain  shield  airbags  will  deploy  in  the  even t  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]).
● Both SRS curtain shield airbags will deploy in the event of veh icle rollover.
● Both  SRS  curtain  shield  airbags  may  also  deploy  in  the  event  of  a severe
frontal collision.
■ Conditions under which the SRS ai rbags may deploy (inflate), other than
a collision
The  SRS  front  airbags  and  SRS  curtain  shield  airbags  may  also  d eploy  if  a
serious  impact  occurs  to  the  underside  of  your  vehicle.  Some  ex amples  are
shown in the illustration.
The  SRS  curtain  shield  airbags  may  also  deploy  under  the  situat ions  shown
in the illustration. ● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.
