It could be due to a blown seat belt fuse. The function of seat belts is to reduce the likelihood of death or serious injury in traffic collisions by minimizing the secondary impact force caused by internal collisions. Here are the relevant details: Hazards of not wearing seat belts: During a vehicle accident or emergency braking, tremendous inertial force is generated. This force varies depending on driving speed and impact severity, causing drivers and passengers to collide with interior components like the steering wheel, windshield, seat backs, and doors, which can easily result in severe injuries or even eject occupants from their seats or the vehicle. Seat belt introduction: A seat belt is a vehicle safety device designed to protect occupants from harmful movement during collisions or sudden stops. By properly positioning occupants, it ensures maximum airbag effectiveness and prevents occupant ejection or vehicle rollover during crashes.

What are the techniques for 0-100km/h acceleration with a manual transmission?

Manual transmission 0-100km/h acceleration techniques are as follows: 1. Preparations: Memorize the positions of all gears. Do not look down at the gearshift while driving, and practice quick and smooth gear changes. 2. Practical techniques: Prepare for takeoff by starting the car, pulling the handbrake, and engaging first gear. Fully depress the clutch, lightly tap the accelerator, slowly release the clutch, and disengage the handbrake to start moving in first gear. Watch the tachometer - when RPM reaches around 2000, quickly depress the clutch and shift to second gear. After shifting, release the clutch and continue accelerating. When RPM reaches around 3000, quickly depress the clutch and shift to third gear. After shifting, release the clutch and continue accelerating. You'll feel clear acceleration and hear the engine roar as RPM approaches 4000, indicating full engine engagement - shift directly to fifth gear. Maintain acceleration in fifth gear, but remember to downshift when speed decreases - shift back to third gear when RPM drops below 3500. 3. Testing requirements: For fifth-gear acceleration in the driving test (Subject 3), some regions allow direct shifting from third to fifth gear, while others require sequential shifting (3→4→5). This depends on local testing regulations.
