Can You Still Drive with a Tire Pressure of 200?

A tire pressure of 200 is too low to drive safely. It is best to adjust it to the normal tire pressure before driving. Normally, the tire pressure for a car should be between 2.2 and 2.5, which is considered safe as long as it falls within this range. The standard original tire pressure for passenger cars is between 2.3 and 2.5 bar, which is within the normal range. The maximum should not exceed 3.0, and the minimum should not be below 2.1. Hazards and impacts of abnormal tire pressure on driving: Impact on braking performance: The friction and adhesion of the tires will decrease, affecting braking performance. Reduced comfort: It can cause steering wheel vibration and deviation, reducing driving comfort. Decreased tire lifespan: It accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan.

Why Does the Car Unlock Automatically?

The reason for the car unlocking automatically might be that one of the four doors was not properly closed when locking the car, or the trunk door was not properly closed. For most car models, if any door is not properly closed, it will prevent the car from being fully locked. Other reasons are as follows: Doors not fully locked: When locking the car, the doors are closed and locked but not fully secured. In this case, even if the lock button is pressed, the doors will not remain locked. Accidentally pressing the unlock button on the remote: After locking the car, other objects in the pocket within the remote's range might accidentally press the unlock button. Many people like to keep their car keys bundled with other keys, making this situation quite common.

What are the consequences if the car expansion tank cap fails to release pressure?

The failure of the radiator cap to release pressure will cause the radiator to malfunction, affecting the normal working performance of the engine. The radiator cap, also known as the pressure radiator cap, is installed on the car's radiator and is an important component of the car's cooling system. The radiator cap is equipped with a valve that generates pressure, helping to maintain the engine at an effective temperature. How the radiator works: When the car is running, the temperature of the radiator increases, and the pressure inside the radiator rises. When the pressure reaches a certain level, the pressure valve is pushed open, allowing the coolant to flow into the adjacent overflow tank. When the car stops running, the cooling system will draw the water back from the overflow tank. Precautions for radiator use: Never fill the car radiator with tap water, as prolonged use of tap water can cause rust or scale buildup in the radiator. This is a very common issue. Rust and scale can restrict the flow of antifreeze in the cooling system, reducing the radiator's heat dissipation performance and, in severe cases, damaging the engine.

Can Water Damage to Car Film Self-Recover?

Water damage to car film cannot self-recover. If the amount of water is relatively small, it may cause the film to become loose, and the film may peel off later. If there is too much water ingress, spreading to some circuits, it may cause a short circuit. Here are some precautions regarding car film application: Wash the car in advance: When applying film to the car, washing the car provides thorough preparation. Dirty car windows will affect the film application effect. Leave sufficient blank space for side mirrors: When applying film to the front two windows, special attention should be paid. The car owner should personally test it by sitting in the car - the film must not obstruct the driver's view of the mirrors. Pay attention to protection: After completing the film application, do not roll down the windows for 3 days, otherwise it will affect the film. Sometimes this may cause the film to become less secure.

What's the reason for a car not performing self-check after power-on?

If a car does not perform self-check after power-on, it may be due to wiring or computer malfunctions. It is necessary to check whether there is an issue with the power supply to the engine control unit (ECU), followed by verifying if the ECU itself is functioning properly. Common reasons for the self-check light to illuminate: Sensor issues: Sensors include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen levels, etc. When these sensors are damaged, have poor connections, or experience signal interruptions, the car's ECU cannot accurately obtain engine data, which may trigger the engine self-check light. Maintenance issues: Poor engine maintenance is the most common reason for the engine self-check light to illuminate. Vehicles have specific maintenance schedules, and if the owner does not adhere to these schedules, combined with poor driving habits, it can increase the operational burden on the engine.

What does turning the car signal lever upward indicate?

Pulling the lever upward activates the right turn signal. The switch is typically located on the left side of the steering wheel. Generally, pushing the lever downward turns on the left turn signal, while lifting it upward activates the right turn signal. Function of turn signals: Although turn signals are electronically controlled devices, they still use sound simulations of relays through audio systems. These important indicator lights are activated when vehicles change direction, serving to alert the driver that the turn signal is flashing while simultaneously notifying surrounding vehicles and pedestrians. Types of turn signals: They can be primarily categorized into three types: resistance wire type, capacitor type, and electronic type. The resistance wire type can be further divided into thermal wire type (electrothermal) and vane type (spring-loaded). The electronic type can also be subdivided into hybrid type (using contact-type relays with electronic components) and fully electronic type (relay-free).
