Nissan LEAF 2023 Owners Manual
5.6.3. Pre-tensioner seat belt system
The pre-tensioner seat belt cannot be reused after activation. It must be replaced together with the retractor and buckle as a unit.
If the vehicle becomes involved in a collision but the pre-tensioner is not activated, be sure to have the pre-tensioner system checked and, if necessary, replaced by a knowledgeable LEAF repairer such as a NISSAN certified electric vehicle dealer.
No unauthorised changes should be made to any components or wiring of the pre-tensioner seat belt system. This is to prevent accidental activation of the pre-tensioner seat belt or damage to the pre-tensioner seat belt system.
Work around or on the pre-tensioner seat belt system should be done by a knowledgeable LEAF repairer such as a NISSAN certified electric vehicle dealer. The SRS wiring should not be modified or disconnected. Unauthorised electrical test equipment and probing devices should not be used on the pre-tensioner seat belt system.
If you need to dispose of the pre-tensioner seat belt system, or scrap the vehicle, contact a knowledgeable LEAF repairer such as a NISSAN certified electric vehicle dealer. Correct pre-tensioner disposal procedures are set forth in the appropriate NISSAN Service Manual. Incorrect disposal procedures could cause personal injury.
The pre-tensioner seat belt system may activate with the supplemental air bag system in certain types of collisions.
Working with the seat belt retractor, it helps tighten the seat belt when the vehicle becomes involved in certain types of collisions, helping to restrain front seat occupants.
The pre-tensioner is encased with the front seat belt's retractor and anchor. These seat belts are used the same as conventional seat belts.
When the pre-tensioner seat belt activates, a fairly loud noise may be heard, followed by the release of smoke. This smoke is not harmful and does not indicate a fire. Care should be taken not to inhale it, as it may cause irritation and choking. Those with a history of a breathing condition should get fresh air promptly.
