2-32 Seats and RestraintsFrontal airbags may inflate atdifferent crash speeds. Forexample:. If the vehicle hits a stationaryobject, the airbags could inflateat a different crash speed than ifthe vehicle hits a moving object.. If the vehicle hits an object thatdeforms, the airbags couldinflate at a different crash speedthan if the vehicle hits an objectthat does not deform.. If the vehicle hits a narrow object(like a pole), the airbags couldinflate at a different crash speedthan if the vehicle hits a wideobject (like a wall).. If the vehicle goes into an objectat an angle, the airbags couldinflate at a different crash speedthan if the vehicle goes straightinto the object.Thresholds can also vary withspecific vehicle design.Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.In addition, the vehicle hasdual-stage frontal airbags.Dual-stage airbags adjust therestraint according to crash severity.The vehicle has electronic frontalsensors, which help the sensingsystem distinguish between amoderate frontal impact and a moresevere frontal impact. For moderatefrontal impacts, dual-stage airbagsinflate at a level less than fulldeployment. For more severe frontalimpacts, full deployment occurs.The vehicle has seat-mounted sideimpact and roof-rail airbags. SeeAirbag System on page 2‑27.Seat-mounted side impact androof-rail airbags are intended toinflate in moderate to severe sidecrashes. In addition, these roof-railairbags are intended to inflateduring a rollover. Seat-mounted sideimpact and roof-rail airbags willinflate if the crash severity is abovethe system's designed thresholdlevel. The threshold level can varywith specific vehicle design.Seat-mounted side impact airbagsare not intended to inflate in frontalimpacts, near-frontal impacts,rollovers, or rear impacts. Roof-railairbags are not intended to inflate inrear impacts. A seat-mounted sideimpact airbag is intended to deployon the side of the vehicle that isstruck. Both roof-rail airbags willdeploy when either side of thevehicle is struck, or if the sensingsystem predicts that the vehicle isabout to roll over, or in a severefrontal impact.If the vehicle does not have a rightfront passenger seat and a rearseat, only the driver frontal airbagwill deploy in a frontal impact.
