How to Escape If a Car Falls into Water?

When a car falls into water, it does not sink immediately. You can use the one and a half to even two minutes before sinking to escape through the doors or windows. Even if the car submerges to the bottom, there are methods to escape because it may take about half an hour for the cabin to fill with water. The exact time depends on whether the windows are open, the car's sealing, and the depth of the water. The deeper the car sinks, the greater the water pressure, and the faster the cabin fills. Here are the steps to handle a car falling into water: 1. Once submerged, do not panic. Hold onto the handrail or the back of the seat tightly, lean back against the seat, and roll with the car as it turns. This prevents passengers from being knocked unconscious before the car rolls into the water, which could lead to drowning due to inability to self-rescue. 2. During the fall, keep your lips closed and teeth clenched to avoid biting your tongue. Cars have some watertight capabilities, so after entering the water, do not rush to open the windows or doors. Instead, close all doors and windows to prevent water from rushing in. The end with the engine will sink first, while the other end's roof will trap a pocket of air, which can be used to survive. If time permits, turn on the headlights and interior lights to see your surroundings and aid rescuers in locating you. Unfasten your seatbelt. Stick your head into the air pocket to breathe. If the engine is in the front, climb to the back seat. Use the time to close windows and ventilation ducts to preserve air inside the cabin. 3. As the car gradually sinks, water will enter through gaps until the pressure inside and outside equalizes, at which point the water level inside the cabin will stop rising. Stay calm and wait patiently during this time. Trying to force open the door when the pressures are unequal will only cause chaos and reduce your chances of escape. 4. Once the water level stops rising, take a deep breath, then open the door or window and jump out. Remove your outer clothing first. If the door cannot be opened, use a car repair tool or wrap clothes around your hand to break the window glass. Exhale slowly as you rise. The air pressure in the car and your lungs matches the water pressure. As you rise, the air in your lungs will expand, and failing to exhale excess air can damage your lungs. 5. If there is more than one person in the car, hold hands and escape together, ensuring no one is left behind.

What is the purpose of automotive urea?

Automotive urea serves the function of treating exhaust gases to reduce pollutants in the emissions. It is a liquid used in SCR (Selective Catalytic Reduction) technology to decrease nitrogen oxide pollution in diesel vehicle exhaust. Its composition consists of 32.5% high-purity urea and 67.5% deionized water. The operation process of the SCR system is as follows: when nitrogen oxides are detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid (DEF). The DEF and nitrogen oxides undergo a redox reaction in the SCR catalytic converter, producing harmless nitrogen gas and water vapor that are then emitted.

What Car Insurance Should You Buy?

Car insurance that should be purchased includes: 1. Compulsory Traffic Insurance: This is a mandatory insurance required by the state, and all vehicles must purchase it; 2. Third-Party Commercial Liability Insurance: Since the compensation amount of compulsory traffic insurance is limited, purchasing third-party insurance can cover the excess amount that compulsory traffic insurance does not cover; 3. No-Deductible Insurance: When compensation is required for an accident, the insurance company normally covers 80% of the loss; 4. Vehicle Damage Insurance: Vehicle damage insurance is a necessary coverage. Whether the car suffers from collisions, scratches, water damage, etc., it can be compensated by the insurance company.

Why do newly replaced brake pads not brake effectively?

Newly replaced brake pads may not brake effectively because their surfaces are not perfectly flat. During braking, small protrusions on the surface will contact the brake disc first, resulting in reduced contact area and lower friction force. This condition will improve after a break-in period. Brake pads are crucial components in the braking system and are also wear-prone parts. It's normal to experience reduced braking force immediately after replacing brake pads. Automotive brake pads, also known as brake linings, refer to the friction materials fixed on the rotating brake drums or discs. The friction linings and blocks bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration.

Can an automatic transmission vehicle be shifted to P gear after turning off the engine?

An automatic transmission vehicle can be shifted to P gear after turning off the engine, but many models do not support this operation. They are factory-set to require shifting to P gear before turning off the engine; otherwise, the engine cannot be turned off. When parking and turning off an automatic transmission vehicle, it is essential to ensure that the handbrake is engaged, and the handbrake must be applied before shifting to P gear. The P (Parking) gear is used for parking and employs a mechanical device to lock the rotating parts of the vehicle, preventing it from moving. When the vehicle needs to remain stationary for an extended period or when leaving the vehicle after parking, the handbrake should be engaged, and the gear lever should be shifted to the P position.
