Safety and security Occupant safety Rif the system determines that air bag deployment can offer additional protection to that provided by the seat belt on whether the seat belt is in of the head-thorax air bags use The passenger air bag 2 will only be deployed if: Rthe Head-thorax air bags G Observe Safety notes, see page 43. Rdepending system, based on OCS weight sensor readings, detects that the passenger seat is occupied 75 indicator lamp in the center console is not lit (Y page 48) impact exceeds a preset deployment threshold Rindependently Rthe Rthe The front air bags in this vehicle have been designed to inflate in two stages. 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 46). 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. Knee bags The driver side knee bag 4 is located on the driver side lower instrument panel. The passenger side knee bag 3 is located on the passenger side below the glove box. They are designed to operate together with the front air bags in certain frontal impacts exceeding a preset deployment threshold. The knee bags operate best in conjunction with properly positioned and fastened seat belts. 1 Head-thorax air bag When deployed, the head-thorax air bags are designed to provide increased protection for the head and thorax (but not for the arms) on the side of the vehicle on which the impact occurs. The head-thorax air bags are deployed: Ron Rin Rif the impacted side of the vehicle side impacts exceeding a preset deployment threshold the system determines that air bag deployment can offer additional protection to that provided by the seat belt Z 45
