There are several methods to open a car when the key is left inside: 1. Use a sharp object to remove the door seal and insert a wire through the gap to press the unlock button; 2. Call the 4S store's after-sales rescue hotline; 3. Use a spare key; 4. Contact a qualified and professional locksmith company; 5. Use adhesive tape to stick to the car window and forcibly pull it open. The working principle of a car key is: it emits a weak radio wave from the owner, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator performs the locking or unlocking action. Car keys are categorized by usage into: 1. Active working mode; 2. Passive working mode; 3. Coil induction mode.

What needs to be replaced in a 30,000-kilometer car maintenance?

For a 30,000-kilometer car maintenance, you need to replace the engine oil, oil filter, air filter, fuel filter, spark plugs, and clean the throttle body. Additionally, depending on the vehicle condition, some 4S shops may recommend other maintenance items, which the car owner should consider and perform based on the actual situation. Replacing the engine oil and oil filter is mandatory. Engine oil, under the harsh conditions of high temperature and high pressure inside the engine, has a significantly shortened shelf life and greatly reduced performance, which over time fails to protect the engine. The oil filter prevents impurities from mixing into the oil, causing oxidation and producing sludge that can block the oil passages. Both the engine oil and oil filter should be replaced simultaneously.

Do new cars need water added to the radiator?

New cars do not require water to be added to the radiator, but it should be checked frequently. Typically, new cars do not need coolant added to the radiator, and if necessary, only antifreeze should be added. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Radiators can be installed in three methods: same-side inlet and outlet, opposite-side inlet and outlet, or bottom inlet and outlet. Regardless of the installation method, the number of pipe fittings should be minimized. Car antifreeze serves multiple functions including cooling, antifreeze, anti-boil, anti-rust, and anti-scale. After use, it forms a protective film on metal surfaces, comprehensively protecting the engine, radiator, water pump, and pipes made of various materials from corrosion. This ensures the normal operation of the engine, effectively improves heat dissipation, and extends the service life of the engine and rubber components.

Why can only 40L be added to a 60L fuel tank?

Because the actual capacity of the fuel tank is greater than the nominal capacity. According to fuel safety regulations, national standards stipulate that the nominal capacity of an automobile fuel tank is 95% of the rated capacity. Therefore, when refueling to full, it can hold 10% more fuel than the nominal capacity. Here is additional information: Refueling precautions: Use automotive gasoline only, as improper fuel entering the fuel system may damage the fuel system and engine; Do not use gasoline containing methanol or alcohol; Avoid spilling fuel on painted surfaces to prevent damage. Purpose: The fuel tank capacity determines the driving range. For two cars with identical engines, the larger the fuel tank, the farther it can travel.
