United Automotive Electronic Systems Co., Ltd. (UAES) supplies the transmission for the Great Wall M4. Established in 1995, UAES is a joint venture between China United Automotive Electronic Co., Ltd. and Robert Bosch GmbH in Germany. The company primarily engages in the development, production, and sales of gasoline engine management systems, transmission control systems, body electronics, hybrid and electric drive control systems. Its headquarters is located in Pudong New District, Shanghai. The AMT transmission, short for Automated Manual Transmission, is an automatic shifting system with microcomputer control based on dry clutches and gear transmissions. The 6AT transmission refers to an automatic transmission with six forward gears, meaning it has six sets of gear groups with different transmission ratios. For the Great Wall M4's transmission, the following points should be noted during daily use: Do not delay transmission fluid changes for extended periods. Prolonged failure to change the transmission fluid can damage internal components such as bearings and the housing. Avoid prolonged coasting in neutral. While many experienced drivers coast in neutral with manual transmissions, doing so with an automatic transmission can cause overheating and create a jolt when shifting back to Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers shift into reverse while still moving to demonstrate smooth operation, but this can severely damage the transmission gears and lead to gear grinding over time. Avoid frequently climbing steep slopes in Drive (D). Automatic vehicles may overheat under heavy load or upshift too early, resulting in insufficient power. In such cases, use manual mode to lock in lower gears or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic vehicle breaks down, it should be transported on a flatbed tow truck with the transmission in Neutral (N). Towing with a rope or dragging the vehicle directly is not recommended.

Why is there water dripping from the exhaust pipe when parking?

Finding water dripping from the exhaust pipe when parking is a normal phenomenon, indicating that the engine is working properly with complete combustion and good atomization effect. There is a small hole at the bottom of each exhaust pipe designed to facilitate drainage under normal conditions or special circumstances like wading through water. The conditions for water dripping from the exhaust pipe after parking are: 1. The air-fuel mixture ratio must meet the normal value. Whether the engine is fuel-injected or carbureted, a normal air-fuel mixture ratio means the vehicle's fuel supply system is functioning properly, and fuel consumption will be within the normal range; 2. The engine cylinder pressure is normal, meaning there is no significant wear inside the engine cylinder, and components like cylinder liners and sealing rings are intact. If there is severe internal wear, gasoline will not burn completely, and no water dripping will occur; 3. The exhaust temperature is normal. Most of the heat generated by the engine stays in the cylinders, with only a small amount reaching the exhaust pipe. In this case, the engine's power output is relatively stable. If the exhaust pipe temperature is too high, the water vapor will evaporate.

What is the service life of Michelin tires?

Generally, the service life of Michelin tires is about 3 years or approximately 50,000 kilometers. The lifespan or mileage of Michelin tires is influenced by many factors as follows: 1. Working air pressure: Both under-inflation and over-inflation will affect the tire's service life. If the tire pressure is too low, its radial deformation will increase, causing excessive deformation on both sidewalls, which leads to shoulder wear on the tread crown. This raises the tire temperature and significantly shortens the tire's lifespan. 2. Climate environment: The local climate conditions in different regions can affect the rubber aging speed of tires. Aged tires lose their proper elasticity, and continued use may cause tread deformation, increasing the risk of blowouts and reducing braking effectiveness. 3. Tire temperature: During driving, tires experience tension, compression, and friction, which raises their temperature. Excessive temperature can accelerate tire wear and even cause blowouts. 4. Driving habits: This is a factor directly related to the car owner. Aggressive acceleration, sudden turns, emergency braking, high-speed driving on rough roads, frequently mounting curbs, and scraping obstacles when parking can all cause severe tire wear, thereby shortening the tire's lifespan.

How to adjust the headlights of Hongqi H7

Here is the method to adjust the headlights of Hongqi H7: 1. There is a height adjustment button in the driver's compartment. 2. Turn it up, the lights go off; turn it down, the lights come on. Here is some related information about headlights: 1. Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only relate to the external image of the car owner but are also closely linked to safe driving at night or in bad weather conditions. 2. The use and maintenance of car lights should not be overlooked. 3. Checking for burnt-out bulbs in exterior car lights is an extremely quick and simple task. 4. Timely maintenance of exterior car lights is crucial for drivers, as this not only affects driving comfort but also directly relates to driving safety. Usually, this is noticed before any warning is given.

Where is the carbon canister located in the Ford Edge?

The carbon canister of the Ford Edge is located near the right rear suspension of the vehicle. Below is relevant information about the carbon canister: 1. The carbon canister is part of the Evaporative Emission Control System (EVAP), which prevents fuel vapor from escaping into the atmosphere after the engine is turned off. 2. If you experience issues such as braking while pressing the accelerator and a strong gasoline smell inside the car, pay special attention to whether the pipes in the carbon canister system are damaged; if the engine idles with a regular fluctuation in RPM and the car lacks acceleration power after starting, check whether the air inlet and filter screen of the carbon canister are blocked. 3. During idling, under the suction of the intake vacuum, the fuel vapor adsorbed in the activated carbon canister is drawn into the intake manifold, causing the oxygen sensor to detect an overly rich air-fuel mixture. As a result, the engine control unit reduces the fuel injector output, leading to a leaner mixture and a drop in idle speed. Subsequently, due to the reduced fuel injection, the oxygen sensor detects an overly lean mixture in the next cycle, prompting the ECU to increase fuel injection, which raises the idle speed again. This results in a regular fluctuation in idle RPM. Therefore, if such symptoms occur, promptly check whether the air inlet of the carbon canister is unobstructed.

What are the reasons why a Mercedes-Benz spare key cannot start the car?

Mercedes-Benz spare key cannot start the car for the following reasons: Key battery is dead: When you press any button on the key, check if the indicator light turns on. If not, the battery is likely dead. Poor contact in the key battery: Remove the key cover, rotate the coin battery, or take it out and reinstall it after a while. Signal interference: Nearby electromagnetic interference or signal interference sources, such as near cameras, telecommunication towers, or high-voltage power lines, can prevent the key from being detected. The car will return to normal once it leaves the interference area. Therefore, keep the key away from such devices when in use.
