This allows the air bags to have different rates of inflation that are based on the vehicle deceleration rate as assessed by the air bag control unit. On the passenger side, the front air bag deployment is additionally influenced by the passenger's weight category as identified by the Occupant Classification System (OCS) (Y page 50). The lighter the passenger side occupant, the higher the vehicle deceleration rate required for second stage inflation of the air bag. The air bags will not deploy in impacts which do not exceed the system's preset deployment thresholds. You will then be protected by the fastened seat belts. The front air bags will not deployed in the event of a rollover unless the vehicle's rate of longitudinal deceleration or acceleration exceeds the preset deployment threshold for the front air bags.
