Reversible seat belt pretensioners
Reversible seat belt pretensioners is a system in the front seats that pulls the seat belts slightly taut prior to a collision. This function helps position the front seat occupants to help improve the effects of other safety systems, e.g., the airbag system.
Seat belt pretensioners in collisions
The seat belts are equipped with standard pretensioners that are triggered according to the severity of a collision.
Seat belt pretensioners in critical situations
In addition to the standard pretensioners, the seat belts in the front seats are also equipped with electric pretensioners.
The pretensioners interact and can be triggered along with the City Safety and Rear Collision Warning systems. In critical situations such as sudden braking, evasive maneuvers, etc., the seat belt can be pulled taut by the pretensioner's electric motor.
The electric pretensioner positions the occupant in the seat to help reduce the risk of striking the interior of the passenger compartment and improves the effect of other safety systems such as the airbags.
Resetting the electric pretensioners
When a critical situation has passed, the seat belt and the electric pretensioner are reset automatically.
Warning
- Never repair the belt yourself; have this work done by a trained and qualified Volvo service technician only.
- Any device used to induce slack into the shoulder belt portion of the three-point belt system will have a detrimental effect on the amount of protection available to you in the event of a collision.
- The seat back should not be tilted too far back. The shoulder belt must be taut in order to function properly.
- Do not use child safety seats or child booster cushions/backrests in the front passenger's seat. We also recommend that children who have outgrown these devices sit in the rear seat with the seat belt properly fastened.
