Seatbelt tensioner

The car is fitted with standard seatbelt tensioners and electric* seatbelt tensioners that can tension the seatbelts in critical situations and collisions.

Standard seatbelt tensioner

The seatbelts in the front seat and at the outer seats in the rear are equipped with a standard belt pretensioner.

The seatbelt tensioner tensions the seatbelt in the event of a collision with sufficient force in order to more effectively restrain the occupant.

Electric seatbelt tensioner*

The driver and front passenger seatbelts are equipped with an electric seatbelt tensioner.

The seatbelt pretensioner works together and can be activated together with the driver support systems for assistance at risk of collision and Rear Collision Warning*. In critical situations, such as panic braking, driving off the road (e.g. the car rolls into a ditch, lifts off the ground or hits something in the terrain), skidding, or risk of collision, the seatbelt can be tensioned by the seatbelt tensioner's electric motor.

The electric seatbelt tensioner helps to adjust the occupant to a better position, reducing the risk of striking the car's interior and improving the effect of safety systems, such as the car's airbags.

When the critical situation has come to an end, the seatbelt and the electric seatbelt pretensioner are restored automatically, but they can also be restored manually.


If the passenger airbag is deactivated, the electric seatbelt tensioner on the passenger side will also be deactivated.


Never modify or repair the seatbelts yourself. Contact Polestar Customer Support.

If the seatbelt has been subjected to a major load, such as in conjunction with a collision, the entire seatbelt must be replaced. Some of the seatbelt's protective properties may have been lost even if the seatbelt does not appear damaged. The seatbelt must also be replaced if it shows signs of wear or damage. The new seatbelt must be type-approved and designed for installation at the same location as the replaced seatbelt.
