62 SAFETY INFORMATION
General Information
When is the Airbag Deployed?
The airbag is only deployed during a head-on collision, where the vehicle hits a fixed or
heavy object with sufficient force. The SRS system registers both the force of the collision
and the internal forces caused by the collision. The control unit determines if the collision is
sufficiently violent for the airbag to be deployed.
Note: The SRS system is only activated once in a collision. If the airbag has deployed, the
following is recommended:
* Have the vehicle towed to an authorized Volvo Truck dealer. Even if the vehicle can be
driven after a collision, it is not recommended to drive the truck with the airbag deployed.
* Have an authorized Volvo Truck dealer change the components in the SRS system.
* Only use original Volvo parts when replacing the SRS system components (airbag, safety
belt, etc.).
