Seat belts and belt tensioners
Each seat belt is equipped with a belt tensioner.
A small mechanism integrated in the inertia reel
is triggered at the moment of impact and
tightens the belt around the body to reduce the
slack caused by soft clothes or the like. This
helps the belt to catch the occupant more
effectively.
WARNING!
If the belt has been subjected to a heavy
load, such as in a collision, the entire belt
including reel, mounting, bolts and buckle
must be replaced. Even if the belt seems
undamaged, some of its protective pro-
perties may have been lost. The belt
should also be replaced if it is worn or
damaged. The new belt should be type
approved and intended for the same seat
as the belt being replaced.
Never modify or repair the belt yourself.
Entrust this work to an authorised Volvo
workshop.
