40 Occupant safety The front air bags increase protection for the driver's and front passenger's head and chest. vehicle deceleration rate required for second stage inflation of the front-passenger front air bag. In the second stage, the front air bags are inflated with the maximum amount of propellant gas available. 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 seat belt. Safety Driver's air bag : deploys in front of the steering wheel; front-passenger air bag ; deploys in front of and above the glove box. They are deployed: the event of certain frontal impacts the system determines that air bag deployment can offer additional protection to that provided by the seat belt Rif the seat belt is fastened Rindependently of other air bags in the vehicle If the vehicle overturns, the front air bags are generally not deployed unless the system detects high vehicle deceleration in a longitudinal direction. Your vehicle has adaptive, dual-stage front air bags. In the event of a collision, the air bag control unit evaluates the vehicle deceleration. When the first deployment threshold is reached, the front air bag is filled with enough propellant gas to reduce the risk of injuries. The front air bag is fully deployed if a second deployment threshold is exceeded within a few milliseconds. Vehicles with OCS (USA only): frontpassenger front air bag deployment is also influenced by the passenger's weight category as identified by the Occupant Classification System (OCS) (Y page 42). Vehicles with OCS (USA only): the lighter the passenger side occupant, the higher the Rif Rin ! Vehicles with BabySmart™ (Canada only): do not place objects heavier than 20 lb (9 kg) on the front-passenger seat, as this could be interpreted as the seat being occupied. In the event of an accident, the restraint systems on the front-passenger side are deployed. Have restraint systems replaced that have been deployed. The front-passenger front air bag will only deploy if: Rthe system, based on the OCS weight sensor readings, detects that the frontpassenger seat is occupied (USA only). Rthe 42 indicator lamp in the center console is not lit, USA: (Y page 42), Canada: (Y page 48). Rthe impact exceeds a preset deployment threshold Side impact air bags G Warning Observe "Important safety instructions" (Y page 38). G Warning! The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers. Improper repair work on the doors or the modification or addition of components to the doors create a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment.
