The car power supply is 12 volts, which is capable of converting 12-volt DC power to 220-volt AC power. Here are some relevant precautions regarding the car power supply: 1. Introduction to car power supply usage: Do not exceed the rated power value of the car power supply when using electrical appliances. Ensure good connections between the car power supply, the battery, and the electrical appliances. 2. Usage environment: Avoid using the car power supply in humid environments. The suitable operating temperature range is 0 to 45 degrees Celsius. Unplug the power supply promptly after charging. Regularly clean the dirt around the car inverter plug to prevent poor contact or abnormal overheating of the converter.

Where is the air conditioning filter located in the Golf?

The air conditioning filter in the Golf is located inside the glove compartment on the passenger side. To replace it, simply remove the glove compartment. The air conditioning filter should generally be replaced every six months or 10,000 kilometers. If the replacement interval is exceeded, the filtering performance of the air conditioning filter will deteriorate, allowing particulate pollutants in the air to enter the cylinders directly, which can lead to carbon buildup. This may result in reduced power, increased fuel consumption, and, over time, a shortened engine lifespan. The Golf is a classic compact hatchback family car, with dimensions of 41999mm in length, 17869mm in width, and 14799mm in height, and a wheelbase of 2578mm. It is equipped with EA211 series 1.6L and 1.4T engines.

What to Do If There Are Cracks on Car Tires?

If there are cracks on car tires, they should be replaced. Rubber products have a service life and will age and crack over time. Continuing to use tires with cracks can lead to the risk of a blowout. Precautions for tire use: 1. Do not turn the steering wheel while stationary; 2. Avoid driving over curbs; 3. Prevent scraping the sidewalls of the tires. The functions of tires include: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface, improving the car's power, braking, and passability, and working with the car's suspension to mitigate impacts during driving and dampen vibrations.

Is a 3-month maintenance mandatory for new cars?

New cars require maintenance after 3 months. The first maintenance for a new car is typically recommended within 3 months or 5,000 kilometers. Precautions during the break-in period of a new car include: 1. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It's best to avoid emergency braking within the first 300 kilometers. 2. Avoid overloading: Running a new car at full capacity during the break-in period can damage components. Therefore, within the first 1,000 kilometers, the load should generally not exceed 75%-80% of the rated capacity. 3. Avoid long-distance driving: Long-distance driving during the break-in period increases the continuous operation time of the engine, which can easily lead to component wear.
