How to Use the Engine Start-Stop Technology?

Engine start-stop technology usage method: While driving, simply press the brake pedal directly. After the vehicle comes to a complete stop for about two seconds, the engine will automatically shut off. As long as you keep pressing the brake pedal, the engine will remain off. Once you release the brake or turn the steering wheel, the engine will immediately restart automatically, allowing you to press the accelerator and start moving right away. The entire process remains in D gear. Engine start-stop technology is a system that automatically shuts off the engine when the vehicle comes to a temporary stop (such as waiting at a red light) and automatically restarts the engine when it's time to move forward again.

How Often Should Air Filters and Cabin Air Filters Be Replaced?

According to the vehicle's maintenance manual, the air filter should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval, while the cabin air filter should be replaced every 10,000 kilometers or approximately once a year. It is recommended to inspect both the air filter and cabin air filter during each maintenance service. The location of the air filter varies depending on the intake design and engine structure, but it is typically housed in the air cleaner on the engine's intake pipe. The cabin air filter is usually located beneath or inside the glove compartment on the passenger side, though in some models, it may be installed under the windshield in front of the passenger seat. The cabin air filter and engine air filter are different components and serve distinct purposes. Air Filter: This is a type of filter, also known as an air cartridge, air cleaner, or element. It is primarily used in engineering vehicles, automobiles, agricultural machinery, laboratories, sterile operating rooms, and various precision workspaces. During operation, the engine draws in a large volume of air. If the air is not filtered, airborne dust particles can enter the cylinders, accelerating wear on the piston assembly and cylinder walls. Larger particles entering the space between the piston and cylinder can cause severe cylinder scoring, particularly in dry and sandy environments. There are two types of air filters in vehicles: dry and wet. Dry filters are made of paper or organic materials, while wet filters are constructed from metal mesh. The purpose of the air filter is to remove particulate impurities from the air, ensuring that clean air enters the cylinders and preventing airborne dust from being drawn into the engine, which could accelerate wear on the piston assembly and cylinders. Cabin Air Filter: This is a filter installed in the vehicle's air conditioning system. It absorbs fine particles, reduces respiratory irritation, minimizes allergens, and protects the air conditioning cooling system. Without a cabin air filter, these particles can enter the cabin, contaminating the air conditioning system, reducing cooling efficiency, and causing health issues such as allergic reactions, lung damage, and irritation from ozone exposure. Unpleasant odors can also affect driving safety. Cabin air filters generally fall into two categories: standard and activated carbon. Standard filters are typically made from a specific eco-friendly filtration material, folded and processed into a single-layer white filter. Activated carbon filters consist of non-woven fabric layers sandwiching fine activated carbon particles, which are then processed into the filter. Dirty Air Filter: Using a heavily soiled air filter can restrict engine airflow, leading to incomplete fuel combustion, unstable engine performance, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The air filter is a device that removes particulate impurities from the air, composed of one or more filtration components. Its primary function is to filter harmful particles from the air before it enters the cylinders, reducing premature wear on the cylinders, pistons, piston rings, valves, and valve seats. Air must pass through the air filter's fine filtration before entering the cylinders. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. If inspection reveals minimal dust and light clogging, the filter can be cleaned using compressed air blown from the inside out and reused. Severely dirty filters should be replaced promptly. Dirty Cabin Air Filter: A clogged cabin air filter can impede airflow, reduce cooling efficiency, increase fuel consumption, and create noise, negatively impacting the air conditioning system's lifespan. Accumulated debris on the filter can harbor bacteria and mold, posing health risks to occupants and potentially leading to serious illnesses.

What are the methods to defog the car interior on rainy days?

Methods to defog the car interior on rainy days: 1. For manual air conditioning, turn on the front window defogging mode, set the fan speed to maximum, turn on the AC switch, and then adjust the temperature to the lowest; 2. Some car models are equipped with rear window electric heating and external rearview mirrors, and the fog can be eliminated in about a minute by simply clicking the switch to turn them on; 3. For automatic air conditioning, generally just press the one-touch defrost button, after pressing, the fan speed will automatically turn to maximum and the external circulation will be activated; 4. Use the heating system to defog. If the car has just been started, do not turn on the air conditioning temporarily. Wait until the engine has preheated for a few minutes and the water temperature rises, then start the heating, set the fan speed to maximum, and turn on the front window defogging mode. The fog will disappear in a few minutes.

What is the cause of the abnormal noise when braking in reverse?

The causes of abnormal noise when braking in reverse are as follows: 1. Normal noise phenomenon: Brake pads are composed of iron plates, graphite, asbestos, etc. When they rub against the brake disc, some metal powder is inevitably produced. At this time, stepping on the brake will produce some squeaking abnormal noise. If the brake pads make such abnormal noises, there is no need to worry too much, because this is a normal noise phenomenon of the brake pads. Stepping on the brake hard several times or stepping on the brake suddenly several times in an open area will improve this situation. 2. Brake pad wear: Another reason for abnormal noise when braking is that the wear of the brake pads has reached the limit. Friction occurs between the brake warning plate and the brake disc, resulting in a metal-on-metal sound. At this time, the braking effect will be significantly reduced, posing a serious threat to the driver's safety. Therefore, it is necessary to replace the car's brake pads in time to prevent danger.

Where is ZheG?

ZheG is the license plate code for Jinhua City in Zhejiang Province. ZheA represents Hangzhou, ZheB represents Ningbo, ZheC represents Wenzhou, ZheD represents Shaoxing, ZheE represents Huzhou, ZheF represents Jiaxing, ZheG represents Jinhua, ZheH represents Quzhou, ZheJ represents Taizhou, ZheK represents Lishui, and ZheL represents Zhoushan. Here is some information about license plates: 1. The first Chinese character on a license plate is the abbreviation of the province or municipality directly under the central government, and the letter following the first character represents the city or district. 2. A license plate is a permit for a vehicle to legally drive on the road. 3. There are two types of car license plates: one is a temporary license plate; the other is a formal license plate. 4. Temporary license plates need to be affixed to the front and rear windshields according to regulations; formal license plates need to be fixed to the front and rear of the vehicle body according to regulations.
