This is the tire pressure monitoring indicator light of the car. If the tire pressure monitoring indicator light stays on after the car completes its self-check, it indicates a fault in the tire pressure of the car, and it is necessary to promptly go to a 4S shop for inspection and repair to prevent tire blowouts and other failures. More details are as follows: 1. The indicator lights on the dashboard can help detect car problems in time. The dashboard indicator lights include the seat belt indicator light, front and rear fog light indicator lights, battery indicator light, fuel indicator light, etc. 2. When an indicator light for a certain system on the car's dashboard lights up, it means that the system has a fault, and the driver needs to be vigilant. 3. If a red indicator light appears, it indicates that the fault has affected the safe driving of the car, and it is necessary to go to a 4S shop for inspection and repair in time.

As a seasoned driver with years of experience, I'm quite familiar with the symbols on the dashboard. That exclamation mark with a wavy line actually represents the tire pressure warning light, indicating insufficient tire pressure. Most modern vehicles are equipped with a Tire Pressure Monitoring System (TPMS), which continuously monitors tire pressure and illuminates the warning light when it falls below the normal range. Possible causes include tire punctures, pressure loss due to temperature changes, or natural depletion from prolonged driving. I've encountered this issue several times—typically, I check for nails or damage in the tires. If none are found, I simply measure the pressure and add some air. Remember, low tire pressure accelerates tire wear, increases fuel consumption, and in severe cases, compromises handling safety. This issue is more common in cold weather, so it's advisable to check and adjust tire pressure before winter sets in.

I remember last time when I was driving on the highway, I suddenly saw that exclamation mark with a wavy line, which made me nervous for a while. Later, I learned it was the tire pressure warning light, indicating abnormally low tire pressure. I immediately pulled over at a rest area to check. Using a portable tire pressure gauge, I found the front tire was underinflated, probably because I hadn't adjusted it as the weather turned cooler. After inflating the tire, the light went off. Don't ignore this warning light—it affects driving stability and braking distance, especially in rainy conditions or when carrying heavy loads, which can be more dangerous. I recommend keeping a small tire pressure gauge in your car and making it a habit to check the pressure every time you refuel. It's easy, convenient, and safer.

I just got my driver's license, and my instructor taught me about that dashboard light. It means the tire pressure warning. When you see the exclamation mark with a wavy line lit up, it indicates low tire pressure. You should find a place to pull over and check if there's a leak, like a nail puncture. If not, it might just be low pressure, and you can go to a gas station or repair shop to add some air. Don't take it lightly, otherwise, the tire could easily burst or make turning difficult while driving. It's good to regularly check and maintain the tire pressure within the normal range.

Where is the car fuel pump installed?

Car fuel pumps are installed inside the fuel tank. The function of the fuel pump is to draw gasoline from the fuel tank and deliver it through pipelines and fuel filters to the float chamber of the carburetor. It is precisely because of the fuel pump that the fuel tank can be installed at the rear of the car, far from the engine and below the engine level. Fuel pumps can be divided into two types based on their driving methods: mechanically driven diaphragm type and electrically driven type. The car fuel pump is one of the fundamental components of the fuel injection system in electronic fuel injection vehicles. It operates during engine startup and while the engine is running. If the engine stops but the ignition switch remains in the ON position, the HFMSFI control module will cut off the power supply to the fuel pump to prevent accidental ignition.
