Seat belt tensioners
Standard seat belt tensioners
All seat belts are equipped with a standard seat belt tensioner.
In a collision of sufficiently violent force, the seat belt tensioners will tension the seat belts in order to more effectively restrain the occupants.
Electric seat belt tensioners*
The driver's and front passenger's seat belts are equipped with electric seat belt tensioners.
The seat belt tensioners interact and can be activated in conjunction with the assistance during collision risks and Rear Collision Warning* driver support systems. In critical situations, such as if the vehicle brakes suddenly, begins to skid or runs off the road (e.g if the vehicle rolls into a ditch, lifts off the ground or hits an obstacle in the road), or if there is a risk of collision, the seat belts can be pulled taut by the seat belt tensioner's electric motor.
The electric seat belt tensioner helps to position the occupant more effectively in the seat, which reduces the risk of the occupant striking the interior of the passenger compartment and improves the effect of other safety systems such as the airbags.
When a critical situation has passed, the seat belt and the electric seat belt tensioner are reset automatically. However, they can also be reset manually.
Important
Warning
Never attempt to alter or repair the seat belt on your own. Volvo recommends contacting an authorized Volvo workshop.
If the seat belt has been exposed to extreme forces, e.g. in conjunction with a collision, the entire seat belt must be replaced. Even if the seat belt appears undamaged, some of its protective properties may have been lost. Also replace the seat belt if it is worn or damaged. The new seat belt must be type approved and intended for the same seating position as the replaced seat belt.
