Resetting the electric seat belt tensioners
The electric seat belt tensioners are designed to be reset automatically, but if the seat belt remains taut it can be reset manually.
Stop the vehicle in a safe location.
Unbuckle the seat belt and then rebuckle it.
The seat belt and the electric seat belt tensioner will be reset.
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.
