Front seat belts
The front seat belts are fi tted with a pretensioning and force limiting system.
This system improves safety in the front seats in the event of a front impact.
Depending on the severity of the impact, the pretensioning system instantly tightens the seat belts against the body of the occupants.
The pretensioning seat belts are active when the ignition is on.
The force limiter reduces the pressure of the seat belt on the chest of the occupant, so increasing their protection.

- Check that the seat belt is fastened correctly by pulling the strap.
Unfastening
- Press the red button on the buckle.
