What to Pay Attention to When Leaving a Car in an Underground Garage for a Long Time?

Here are the precautions for leaving a car in an underground garage for a long time: 1. Pay attention to the protection of the wiper blades: Wiper blades are components that are prone to aging. They can freeze in very cold weather and stick to the glass in very hot weather, so they can be lifted up. 2. Tire protection: Tires are also prone to aging. When left stationary for a long time, the side in contact with the ground will gradually deform due to gravity, making them uneven when used. Therefore, the tire pressure should be increased to 300 kPa. If possible, lift the car to protect the tires and suspension system effectively. 3. Keep the interior clean and dry: A humid environment can cause rust on the interior components and wiring. If there is uneaten food left inside, it can mold. Also, make sure to close the windows properly, or mice may become interested in anything they can chew.

What is a License Plate Quota?

License plate quota can be considered as the qualification to obtain a license plate. With an increasing number of people needing to purchase cars, the allocation of motor vehicle license plate quotas is determined through a lottery system. Those who win the lottery have obtained the quota, and only with this quota can they proceed to the vehicle management office to receive their license plates after purchasing a car. Additional information about license plates is as follows: 1. Vehicle license plates are plates hung on the front and rear of a vehicle, typically made of aluminum, plastic, or stickers, displaying the vehicle's registration number, registration region, or other basic information. License plates serve as unique identifiers for vehicles. 2. The primary function of vehicle license plates is to identify the province, city, or county to which a vehicle belongs. The vehicle management office can use the license plate to trace the owner of the vehicle.

What is the purpose of the S mode?

S mode is the sport mode of a car (S stands for sport). In S mode, the transmission can shift gears freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer period. This allows the car to maintain a lower gear with higher RPM for an extended duration, resulting in greater torque output and acceleration. Here are some related details: Control usage time: Since S mode only delays upshifting without altering other operational aspects, it inevitably increases the transmission load in a short period, accompanied by rising temperatures and accelerated wear. Therefore, try to avoid prolonged use of S mode.

What is the standard tire pressure for rear car tires?

The standard tire pressure for rear car tires is 2.4-2.5bar. There may be slight variations depending on different vehicle models, and specific values can usually be found on the fuel tank cap, the side of the driver's door, or in the user manual. Normal tire pressure reference standards: According to the international GBT2978-2008 standard, the standard tire pressure for regular tires is around 2.4-2.5bar, while reinforced tires require around 2.8-2.9bar. In winter, it is advisable to increase the tire pressure by approximately 0.2bar based on the standard, whereas in summer, the pressure can be slightly reduced by about 0.1bar from the standard to prevent blowouts due to high temperatures. For empty or half-loaded conditions, adjust to the lower limit of the standard tire pressure; for full load, use the upper limit. On rough roads, it is recommended to reduce the tire pressure by 0.1-0.2bar from the standard. Daily tire pressure precautions: Most cars are equipped with a tire pressure monitoring system that alerts drivers to leaks or abnormal tire pressure to ensure driving safety. Pay attention to the tire pressure monitoring light on the dashboard, as both underinflation and overinflation can affect driving performance and accelerate tire wear.

Does Replacing Car Antifreeze Take an Hour?

Replacing antifreeze generally takes about an hour in winter and half an hour in summer. Method for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way water pipe. The five-way pipe is named for its five connecting interfaces to various parts. Antifreeze flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of antifreeze in this part, the water pipe should be replaced or the interface re-secured as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue injecting water into the reservoir to allow the water to flow continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding clean water until clear water flows out. Remember to disconnect the heater hose and drain the water from the heater core. After about an hour of draining, add the new antifreeze through the radiator hose, which allows the antifreeze to flow quickly into the radiator. Then, add another container of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop as air is expelled from the cooling system. Add more antifreeze until the reservoir reaches the "MAXT" mark.
