Why doesn't the Q5L passenger seat belt warning sound?

[SanIsabelle]

Whether the passenger seat unbuckled seat belt warning sounds depends on whether the vehicle is equipped with this feature. If equipped, the warning will sound when the seat belt is not fastened; if not equipped, there will be no warning. Many vehicles have this feature only in higher trims, not in base models. Additional information: 1. Working principle: Most car seats have a pressure-sensitive switch hidden in the seat cushion. The alarm will only sound when the vehicle reaches a certain speed, the sensor is triggered, and the seat belt is not fastened. 2. Alarm: If the warning sounds when no one is sitting in the passenger seat, it could be due to a blown fuse. If the fuse is not the issue, the seat pressure sensor might be faulty. Replacing it is very troublesome, requiring the seat to be disassembled, the upholstery removed, and then sewn back after installation. Hopefully, the issue is simply a poorly connected sensor. Therefore, if the seat belt warning light doesn't alert when the seat belt is unbuckled, you should check whether the seat sensor is functioning properly.
