MRS deployment logic provides two
thresholds for the activation of the safety
system, depending upon the severity of
impact and whether or not occupants
have fastened their seat belts:
Belts fastened, low impact speed:
Lower deployment threshold. Only
seat belt pyrotechnic tensioners are
deployed.
Belts fastened, high impact speed:
Higher deployment threshold.
Tensioners and front-impact airbags
are deployed.
Belts not fastened, low or high
impact speed: Airbags are
deployed.
Passenger seat not occupied:
Neither belt tensioner nor airbag is
deployed on that side.
