Adaptive SEATBELT Force Limiter
Never use an ohmmeter or similar tool to test airbags, door mounted inflatable curtains, adaptive seat belt tensioners, the adaptive steering column, rollover bar cassette or seat belt tensioners. Disconnect airbags, door mounted inflatable curtains, adaptive seat belt tensioners, adaptive steering column, rollover bar cassette or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
The adaptive seatbelt force limiter improves the seatbelt function in the event of a frontal collision when the airbag has been activated. There are two adaptive seatbelt force limiters in the car. These are integrated in the seat belt reel, positioned at shoulder height on the driver's and front passenger seatbelts.
The adaptive seatbelt force limiters are electrically separated from each other. The adaptive seatbelt force limiters have a pyrotechnic charge which adapts the seatbelt force to a lower level against the chest on activation.
The adaptive seatbelt force limiter, seat belt reel, seat belt (inertia) reel sensor and seat belt tensioner are installed in a single unit. In the event of a fault in any of these the whole unit must be replaced.
