BST Trigger Logic
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.
Triggering of the BST requires no additional sensors. The MRS II control module will trigger the BST as follows:
FRONTAL COLLISION: During a frontal collision that involves deployment of any front air bag, the BST will also be triggered
SIDE IMPACT: Depending on the severity of the side impact, the BST may also be activated.
REAR IMPACT: Detection of server rear impact will cause the MRS II to activate the seat belt tensioners and simultaneously activate the BST.
