The driver and front passenger seats are equipped with a seat belt pretensioner that deploys simultaneously with the airbags in the event of a moderate to severe frontal collision. In various frontal collisions from moderate to severe, the seat belt pretensioner instantly retracts the belt, holding the occupant's body tightly with the seat belt, which, in combination with the airbag, makes the passive safety system more effective. The pretensioner is located in the seat belt inertia reel housing. Using such belts is similar to standard seat belts. When the seat belt pretensioner is deployed, a loud bang is heard and smoke is released. This smoke is practically harmless to humans, but you should not inhale it, as this can cause difficulty breathing and coughing. The seat belt pretensioner is deployed by any strong impact applied to the front of the car, even in cases where the seat belt is not fastened.
The seat belt pretensioners may not deploy in certain frontal collisions, even if the vehicle is severely damaged. This failure does not indicate a malfunction of the SRS system, but rather that the collision forces were not strong enough to activate the SRS system.
Warnings
- (1) The seat belt with pre-tensioner mechanism cannot be used once it has been activated and must be replaced together with the belt tensioner.
- (2) If the vehicle has been involved in a frontal collision but the seat belt pre-tensioner mechanism has not been activated, have the mechanism checked and, if necessary, replaced by a MITSUBISHI dealer.
