Driver's Front Airbag
WARNING: This page does not describe the selected car, but rather 151 other vehicles, including the 2006 BMW X5, 2006 BMW M3, 2006 BMW 330Ci, 2006 BMW 325Ci, and 2005 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
The deployment threshold for the driver's front airbag is designed so that minor impact forces, will not trigger the airbag, where the seat belt is sufficient to protect the driver. If the seat belt is not connected, the driver's front airbag will deploy to provide the driver with protection.
