What is the reason for the lack of sound prompt when the Lavida front passenger seat belt is not fastened?

Lavida front passenger seat belt does not have a sound prompt because the front passenger seat belt warning function is faulty. It is recommended to check at a 4S shop or repair shop, mostly due to poor contact. Main functions of seat belts: The main functions of the seat belt shoulder strap and waist belt are to cushion the inertia of the driver and passengers forward or backward in the event of an accident, and to fix them in the seat as much as possible. When wearing the seat belt correctly, the shoulder strap should cross the chest cavity, and the waist belt should fit snugly against the hip bone. Avoid friction: When using the seat belt, be careful not to let the seat belt rub against sharp blades to avoid damaging the seat belt; do not tilt the seat back too much, otherwise the seat belt will not extend and retract correctly; when no one is in the seat, the seat belt should be sent to the retractor to avoid the buckle tongue hitting other objects during emergency braking.
The lack of sound prompts for the co-driver's seatbelt in the Lavida is mainly due to sensor issues. A sensor is installed under the co-driver's seat to detect when someone sits down. If it's covered with too much dust or the wiring is aged, the system may fail to detect a person and thus won't remind about the seatbelt. The seatbelt buckle switch might also have poor contact or a stuck spring that doesn't retract, preventing the signal from reaching the computer. A blown fuse is another common cause, as it cuts off power affecting not only the headlights but also the seatbelt reminder. I've personally experienced this; cleaning the seat sensor improved the situation. It's advisable to test the warning sound after starting the vehicle to identify issues early. Long-term neglect could lead to more faults, making repairs more costly and troublesome.
