How to Self-Rescue When a Motor Vehicle Accidentally Submerges and the Doors Cannot Be Opened?

When a motor vehicle accidentally submerges and the doors cannot be opened, the first priority is to remain calm. The fastest self-rescue method is to break the side window glass, so it is essential to have a safety hammer in the vehicle. In the moment the vehicle accidentally submerges, the safety hammer can effectively shatter the window, allowing escape in the shortest possible time. If the vehicle accidentally submerges, due to water pressure, the doors will inevitably be impossible to open. The first step is to stay calm and avoid panic. Do not hastily unfasten the seatbelt. Utilize the precious time before the cabin is completely submerged to quickly determine the direction of the water surface. Generally, the direction with brightness is the water surface. Quickly roll down the window to allow water to enter the cabin. Once the cabin is half-filled with water and the internal and external water pressure equalizes, promptly unfasten the seatbelt and open the door to escape. When the driver urgently breaks the window to escape, the side window should be the first choice for breaking. The front windshield is thicker and often made of laminated glass, making it difficult to break. Even if shattered, it does not easily break away in large pieces to quickly form an escape exit. In contrast, the side window glass is thinner than the front windshield and easier to break. Additionally, when breaking the window, aim for the edges or corners of the glass for a more effective strike.

What are the symptoms of poor ignition in the ignition coil?

Symptoms of poor ignition in the ignition coil: 1. At idle, the car body shakes noticeably. Observe the exhaust pipe outlet, and you will see that the exhaust gas flow has obvious intermittency, accompanied by severe shaking of the exhaust pipe and clearly audible popping sounds. 2. While driving, when the engine speed is below 2500 rpm, the car body shakes noticeably with poor acceleration. However, the shaking disappears once the speed exceeds 2500 rpm. 3. Open the engine hood and observe the running engine; you will notice significant shaking. This level of shaking is clearly abnormal for a properly functioning engine, with a very large amplitude of vibration.

Where to Add Antifreeze?

Automobile antifreeze is added to the car's radiator. The car radiator, also known as the heat exchanger, is a key component of the car's cooling system, and its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator where the heat is dissipated, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. Antifreeze prevents the coolant from freezing when the car is parked in cold winter, which could otherwise cause the radiator to crack or the engine cylinder block to freeze. It also has excellent properties such as year-round anti-scaling and anti-corrosion.

What is a foot brake called?

Foot brake refers to the parking foot brake, a type of parking brake operated by the foot, commonly found in automatic transmission vehicles. Parking brake types refer to the operation methods of parking brakes. Currently, passenger vehicles have three main types of parking brake operations: handbrake, foot brake, and electronic parking brake. The structure of the foot brake is essentially the same as that of a conventional mechanical handbrake, also using a steel wire cable. The only difference is that the control terminal is changed from a handbrake lever to a foot brake pedal, usually positioned near the left foot. Generally, foot brakes are more commonly used in mid-to-high-end vehicles, mainly in medium-sized and larger cars, and are frequently seen in Japanese and Korean brands, predominantly in automatic transmission models. Currently, there are very few Chinese-brand vehicles equipped with foot brakes. Foot brakes are more suitable for female drivers. The actual locking force of a conventional handbrake is typically around 200N, equivalent to lifting a 20-kilogram object. For many female drivers with limited upper body strength, this can be quite a challenge, often resulting in insufficient parking brake force due to inadequate pulling force, leading to vehicle rollback. In contrast, the foot brake relies entirely on the left foot for control, requiring just a light press to exceed 200N, making it more reliable and safer than a handbrake. Service brake: During driving, the service brake (foot brake) is generally used to slow down or stop the vehicle while in motion. It is not only used to keep the car stationary. The parking brake is only used when the service brake fails. Once the vehicle is stationary, the parking brake (handbrake) should be engaged to prevent the vehicle from rolling forward or backward.

What to Do If Your Driver's License Expired One Month Ago?

You can simply renew your driver's license if it has been expired for one month. Below are more relevant details: Important Notes: After your driver's license expires, you are no longer allowed to drive a motor vehicle. Driving without a valid license may result in administrative detention for up to 15 days. If your driver's license has been expired for one month, you need to bring your identity proof and its copy, a passport-sized color photo, your driver's license, and a medical examination report to the vehicle management office to apply for a renewal. If your driver's license has been expired for over one year without renewal, your driving qualification will be revoked, and you will need to retake the exams to regain it. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": A motor vehicle driver should apply for a renewal at the vehicle management office where the license was issued or another office 90 days before the expiration date. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": If a driver's license has been expired for over one year without renewal, the vehicle management office shall revoke the driver's license. Generally, you can still renew your driver's license if it has been expired for one month. However, driving with an expired license will result in a fine: The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulates: Article 95, If a motor vehicle driver commits any of the following acts, the traffic management department of the public security organ shall impose a fine; Obtaining a replacement driver's license through concealment or deception while the original license is legally seized, detained, or suspended; Continuing to drive a motor vehicle despite physical conditions that no longer meet the requirements for driving, or failing to undergo the required review and still driving. If any of the circumstances listed in the first or second item of the first paragraph occurs, the traffic management department of the public security organ shall revoke the driver's license.

What Causes the Steering Wheel to Become Heavier in Electric Power Steering Vehicles?

Reasons for heavier steering wheel in electric power steering vehicles: 1. For hydraulic power steering, the power steering fluid may be contaminated; 2. For electric power steering, check if any fuses are blown or if there are open/short circuits in wiring; 3. Repeatedly turning the steering wheel while stationary or at low speeds places extreme load on the power steering system, easily causing the steering gear to overheat and enter protection mode (resulting in heavy steering) - this will return to normal after cooling down and is a normal phenomenon; 4. If electric power steering becomes heavy, check whether the plane bearing above the shock absorber is functioning properly or if excessive wheel alignment deviation is causing the issue; 5. Insufficient tire pressure can make the steering wheel feel heavier - restoring to standard tire pressure will return it to normal.
