The reasons for a car not starting are as follows: 1. Improper fuel quality, lack of antifreeze, excessive carbon buildup, excluding improper human operation. 2. Starter motor failure, fuel pump supply issues, injector problems, sensor malfunctions, etc. These more complex situations require professional handling. Below are some vehicle usage precautions: 1. Fuel quality issues: During repairs, it was found that the fuel tank contained water and sludge. Using such fuel will inevitably damage the car. Always refuel at reputable gas stations, and when traveling, you can use a gauze filter over the fuel nozzle to filter out impurities. 2. Lack of antifreeze: Using water or substandard antifreeze in extremely cold winter conditions can cause the entire cooling system to freeze, potentially cracking the engine block, rendering the water pump inoperable, preventing the car from starting, and damaging other engine components. 3. Excessive carbon buildup in the vehicle can also prevent it from starting. Regular use of the car helps reduce carbon buildup.

I've been driving for over a decade and have encountered many situations where the car wouldn't start. The most common reason is a dead battery, either due to aging or leaving the lights on and draining it. You can try turning the key and listening for sounds—if there's no response at all, it's likely a battery issue. Or if the engine doesn't crank when you turn the key, the starter motor might be faulty. Other possibilities include poor contact in the ignition switch or loose battery terminals. I remember last winter when my car was parked in the snow overnight and wouldn't start in the morning—turns out the battery had frozen and short-circuited, but replacing it solved the problem. Additionally, a malfunctioning fuel pump, faulty spark plugs, or a blown fuse in the circuit can also cause starting issues. My advice is to first try jump-starting or push-starting the car, and if that doesn't work, call a tow truck to take it to a professional repair shop immediately to avoid worsening the problem. Regular maintenance is crucial—check your battery's lifespan annually to prevent unexpected failures.

How to Drain Water from Car Doors?

The bottom of car doors is equipped with drainage valves, which automatically open when water accumulates inside, allowing the water to drain out. Here are detailed methods: 1. If there is a large amount of water, visit a 4S shop to remove the door and use tissues or similar items to wipe the water dry, preventing accumulation. The drainage holes will naturally drain water, but if they are clogged, press the drainage valve manually. 2. Press the drainage valve to gradually widen the gap, then gently lift it to let the water drain out. The valve will automatically retract after draining. 3. If the water inside the door is severe, it needs to be cleaned promptly.

Below is relevant information about airbags: 1. How airbags work: An airbag is a passive safety system device that is only activated when the vehicle experiences a severe impact. Airbags determine whether to deploy based on pressure sensors in the airbag system and acceleration sensors in the restraint system ECU. 2.
