The reasons why the airbag light stays on are: 1. Circuit issues; 2. Loose connectors; 3. Sensor failure; 4. Instrument self-check. The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, the airbag can reduce head injury rates by 25% and facial injury rates by 80%. Precautions for using airbags include: 1. Use airbags together with seat belts; 2. Maintain an appropriate distance from the airbag when seated; 3. Do not place objects in front of, above, or near the airbag; 4. Avoid high temperatures, and the components of the airbag device should be properly stored; 5. Do not modify the airbag system or its surrounding layout without authorization.

That airbag warning light staying on is really unsettling, and I reckon there could be several reasons behind it. The most common one is a loose sensor connection—like the wiring under the seat that can get knocked loose or corroded, leading to poor contact. Also, starting the car with a low battery voltage might trigger a false fault and light up the warning. You should also consider issues with the airbag control module, such as a faulty circuit board that prevents it from functioning properly. Or, after hitting a big bump, connectors might loosen and short-circuit. I’ve tried restarting the car a few times myself, and sometimes the light goes off, but if it stays on, you must take it seriously because it means the airbag system might fail to deploy in an emergency. It’s best not to delay—first, check if the wiring under the seat is secure, and if that doesn’t help, head to a professional auto shop to scan for trouble codes and pinpoint the root cause to ensure safety. Don’t skimp or ignore this little light—it’s about protecting your life while driving. Timely repairs can save you from bigger trouble.

What is the 0-100 km/h acceleration time of the Audi S4?

According to official data, the Audi S4 has a 3.0T engine displacement with a 0-100 km/h acceleration time of 9.1 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in layman's terms, represents how much force is available. The greater the torque, the stronger the force pushing the vehicle, resulting in naturally faster acceleration. The BMW 320i has a maximum torque of 205 Nm and a 0-100 km/h acceleration time of 9 seconds. The Audi S4 has a torque of 500 Nm and a 0-100 km/h acceleration time of 4.7 seconds. Transmission efficiency: The transmission serves as the medium for power delivery, inevitably involving power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Audi S4 is equipped with a manual-automatic transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is referred to as the power-to-weight ratio (unit: Hp/T). The higher the power-to-weight ratio, the faster the acceleration. The BMW 320i has a power-to-weight ratio of 106 Hp/T and a 0-100 km/h acceleration time of 9 seconds. The Audi S4 has a power-to-weight ratio of 199 Hp/T and a 0-100 km/h acceleration time of 4.7 seconds.

How to Use Reference Points for Parallel Parking?

Parallel parking using reference points involves the following steps: 1. Before parallel parking, adjust the vehicle position. When the front wheels cross the parking line, slow down and observe the left rearview mirror. When the lower edge of the mirror aligns with the parking line, prepare for parallel parking. 2. While reversing, observe the right rearview mirror. When the right rear wheel appears parallel to the curb line, immediately turn the steering wheel fully to the right. 3. Observe the left rearview mirror. When the inner corner of the parking space becomes visible, straighten the steering wheel. 4. Continue observing the left rearview mirror. When the left rear wheel touches the curb line, turn the steering wheel fully to the left. 5. Following this method, the vehicle will gradually align. Observe both left and right rearview mirrors. When the car body is parallel to the curb lines on both sides, straighten the steering wheel to complete the parallel parking.

What is the treatment method for yellowing headlight covers?

Use white Headlight-Lens-Restorer to wipe, apply transparent paste on a dry cloth, and then scrub vigorously. At this point, the car headlights should have become completely transparent, so there is no need to use sandpaper to polish them. Sandpaper polishing is only required for headlights with severe yellowing and oxidation. The following introduces the repair method for yellowing headlight covers: 1. First, spray a small amount of degreaser on the surface of the headlight cover, then wipe the headlight surface with a damp cloth until the moisture or dirt is completely removed. 2. Use pre-prepared single-sided adhesive tape to stick around the outline of the headlight (green part), and cover the outer outline of the headlight with newspaper or similar material where the tape is applied. 3. Next, begin the repair work. First, spray the repair agent on the headlight part, keeping a distance of 15-20cm from the headlight to prevent splashing of the repair liquid during spraying.
