What is the purpose of the hole under the car steering wheel?

The hole under the car steering wheel serves as an exit point for the airbag to deploy in the event of a collision, functioning as a crucial safety device to protect the driver. The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective crash protection for the driver. In the event of a collision, car airbags can reduce head injury rates by 25% and facial injury rates by 80%. An airbag is a type of vehicle occupant restraint system, designed to inflate rapidly during a collision and then quickly deflate, aiming to provide a soft cushion and restraint for the occupants during a crash. The steering wheel is primarily composed of a frame, foam, and mounting clips or screw holes corresponding to the driver airbag (DAB).

How to Identify Whether a Tire is Retreaded?

Methods to identify whether a tire is retreaded: 1. Tire production date: Generally, tires should not be stored for more than 3 years from the production date and should not be used for more than 8 years after installation; 2. Observe the tread pattern and color: In terms of the tread, retreaded tires of inferior quality often have shallower grooves due to irregular processing, and retreaded tires are usually dyed in very bright colors, whereas new tires from reputable manufacturers are not; 3. Check the tread pattern code: Mainly verify if the pattern matches the identification, and also check if there are any signs of bonding on the tire sidewall; 4. Inspect the tire markings: Generally, the markings on retreaded tires are reattached. If you can scratch them off with your fingernail, it is a retreaded tire.

What do China 5 and China 6 vehicles mean?

China 5 and China 6 vehicles refer to automotive exhaust emission standards, which regulate the content of harmful gases such as carbon monoxide, PM, and soot emitted from vehicle exhaust. The higher the number, the later the standard was issued, and the stricter the energy-saving and emission-reduction requirements for vehicles. The transition from China 5 to China 6 includes improvements in intake and exhaust efficiency, exhaust gas recirculation efficiency, etc., with the aim of reducing the levels of harmful gases. The China 6 emission standard is an upgraded version of the current China 5 standard, imposing more stringent limits on the emission of carbon monoxide, total hydrocarbons, non-methane hydrocarbons, nitrogen oxides, and particulate matter mass compared to the China 5 standard. Additionally, it introduces new regulations on the number of particulate matter emissions.

What part does the safety headrest in Subject One protect?

Subject One safety headrest protects the neck safety of drivers and passengers. Here are the relevant introductions: 1. Position of the headrest: Adjust the height of the headrest to the level of the occupant's eyes or the upper edge of the ears, and the closer the back of the head is to the car headrest, the better, preferably not exceeding 10 cm, which can maximize the protection of the driver and passenger's neck safety. 2. Function of the headrest: While providing comfort for drivers and passengers, the car headrest can better protect the neck safety of drivers and passengers in the event of a traffic accident. For example, in collision accidents such as rear-end collisions, a huge impact force will be generated, causing the head of the driver and passenger to violently tilt backward. In this case, the fragile neck is very vulnerable to injury, and even fatal injuries may occur.

When practicing driving on rainy days, choose shoes with textured soles. Shake off any water on the soles before getting in the car, and rub the shoes against the floorboard a few times before placing them on the clutch or brake to avoid slipping. Dry your hands before placing them on the steering wheel to prevent slipping. 3. On the lower right side of the steering wheel, opposite the turn signal button, is the windshield wiper button.
