How to reset the maintenance wrench on the old Chery e5?

The method to reset the maintenance wrench on the old Chery e5 is as follows: 1. Make sure the car is turned off, locate the menu toggle button on the steering wheel, insert the key, and hold down the toggle button without releasing it. 2. Turn the key to the second position, which is the ON position, to power on the car and start the self-check. 3. Wait for the self-check to complete, while still holding down the toggle button. After five seconds, the maintenance will be reset. More information about the Chery e5 is as follows: 1. The front face design of the Chery e5 features a more rounded clam-shell structure for the engine hood. 2. The newly designed headlights of the Chery e5 incorporate some popular fashion elements, with a sharp, angular quadrilateral shape.

How to Activate the Lock Sound on Volkswagen Tiguan?

It cannot be set by yourself and needs to be activated by flashing the ECU. You can visit a 4S store to have it done. Below is relevant information: 1. Lock sound prompt function In the factory settings of Volkswagen models, the horn does not sound by default when the doors are locked. The lock sound requires flashing the data (OBD vehicle system, modifying settings). After enabling this function, when you hear the horn sound upon locking, you don’t need to worry about the doors not being locked. 2. ECU flashing, currently also known as ECU upgrade, car computer upgrade, or ECU modification in China. The formal translation is actually ECU tuning. How ECU flashing works: It involves rewriting the program to finely adjust the fuel supply and ignition timing based on the original factory data or to unlock hidden functions set by the factory. By optimizing parameter settings, it aims to increase horsepower, enhance torque, or reduce fuel consumption. Increasing horsepower and torque will correspondingly increase fuel consumption, while decreasing horsepower and torque will reduce fuel consumption.

How to Dispose of Old Tires After Replacement?

Replaced old tires can be placed back in the original spare tire storage location. If the damage is not significant, they can be repaired and kept as a spare tire or sold to an auto parts market. Before replacing tires, first, park the car in a relatively safe and flat area, then firmly engage the parking brake, shift the gear to the parking position, turn the ignition switch to the "lock" position, activate the hazard lights, and place a triangular warning sign at a sufficient distance from the vehicle. Below are the disposal methods for sold old tires: 1. Tire Retreading: Tire retreading technology involves refurbishing worn or damaged tires through repair processes to restore their usability. 2. Converting Waste Tires into Fuel Using Catalysts: The technology of converting waste tires into fuel involves heating and pressurizing waste tires to extract fuel. However, using simple and cheap equipment for this process can easily cause secondary pollution. 3. Rubber Powder Regeneration from Tires: This technology first uses waste tire rubber powder equipment to crush tires into 20~30 mesh rubber powder, followed by desulfurization treatment to soften the rubber powder into malleable recycled rubber, which can then be reprocessed into various rubber products. If the desulfurization process is not up to standard, it can also lead to pollution. 4. Rubber Powder for Waterproofing and Leak Prevention: Waterproof membranes are mainly used for building leak prevention. Most buildings now undergo waterproofing and leak prevention measures, making this a widespread industry nationwide. The demand for waterproof membranes is enormous, and rubber powder is a key raw material in this technology, as waterproof membranes also fall under modified asphalt.

What does the engine oil grade 0w20 mean?

The engine oil grade 0w20 means the freezing point temperature of the oil is -35°C, and its kinematic viscosity at 100°C is 20. In 0w20, the 'W' stands for WINTER, indicating winter use. The number before 'W' represents the freezing point temperature: 0W is -35°C, 5W is -30°C, 10W is -25°C, and 15W is -20°C. The number after 'W' represents the oil's kinematic viscosity at 100°C, with higher numbers indicating higher viscosity. Below are some considerations when selecting engine oil: 1. Choose engine oil based on the engine's requirements. It's unnecessary to use overly advanced oil in engines with lower requirements, nor should you use lower-grade oil in engines with higher requirements. 2. Try to choose multi-grade oil. Multi-grade oil is economical, has a long lifespan, and is highly efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, it may appear darker prematurely and have lower oil pressure compared to conventional oil, which is normal.

Manual Transmission Gear Shifting Principle?

Manual transmission works by utilizing combinations of gears with different tooth counts engaged in meshing transmission to achieve changes in rotational speed and torque. A manual transmission is a gear-shifting device used to alter the rotational speed and torque transmitted from the engine to the driving wheels. It enables the vehicle to obtain different traction forces and speeds under various operating conditions such as starting from standstill, climbing hills, turning corners, and accelerating, while also allowing the engine to operate within a more favorable working range. Manual transmissions consist of two main components: the gear-shifting transmission mechanism and the gear-shifting control mechanism. The transmission mechanism primarily includes components such as the input shaft, output shaft, reverse gear shaft, various gear sets, synchronizers, bearings, and housing, with some models also featuring an intermediate shaft. Its function is to alter torque, rotational speed, and direction. The control mechanism mainly comprises operating devices, locking devices, and covers, and its role is to execute gear-shifting operations. During gear-shifting operations, especially when downshifting from higher to lower gears, impacts between gear teeth or spline teeth can easily occur. To prevent inter-tooth impacts, synchronizers are installed in the shifting mechanism. Synchronization involves creating frictional contact between the sleeve's teeth and the gear (blue) before engagement. The conical protrusion on the gear (blue) fits precisely into the conical recess of the sleeve, with the friction between them causing the sleeve and gear (blue) to synchronize. The sleeve then slides externally to engage with the gear.

How are the letters in Gansu license plates arranged?

Gansu license plate letters are arranged as follows: GanA: Lanzhou City; GanB: Jiayuguan City; GanC: Jinchang City; GanD: Baiyin City; GanE: Tianshui City; GanF: Jiuquan City; GanG: Zhangye City; GanH: Wuwei City; GanJ: Dingxi City; GanK: Longnan City; GanL: Pingliang City; GanM: Qingyang City; GanN: Linxia Hui Autonomous Prefecture; GanP: Gannan Tibetan Autonomous Prefecture. Below are the colors of vehicle license plates: 1. Special license plates for new energy vehicles: green background with black characters and black borders. New energy vehicle license plates feature a gradient green color, while large new energy vehicle license plates have a yellow-green dual-color scheme (the regional code part is yellow, and the number part is green). 2. Large vehicle license plates: yellow background with black characters and black borders. These are for medium-sized (and above) passenger and cargo vehicles, special operation vehicles, semi-trailer tractors, and electric vehicles. 3. Small vehicle license plates: blue background with white characters and white borders. These are for medium-sized and below passenger and cargo vehicles and special operation vehicles. 4. Police vehicle license plates: white background with black characters (the character "Jing" is in red) and black borders. There is a dot before and a slash after between Chinese characters and letters. These are for police vehicles.
