Activating The Collision Protection System
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
The collision safety system is extremely advanced. It is able to adapt the collision protection system to suit the specific circumstances of a collision. In general it is extremely unlikely that all airbags and seat belt tensioners will be deployed in the same accident. It is possible that only one airbag or seat belt tensioner is deployed. This is determined by the supplemental restraint system module (SRS) based on the forces that occur during the collision.
If the control module deploys the front airbags, all stages will always be activated. By varying the time between the deployment phases, the inflation of the airbag is more gentle for a low speed collision.
