How to use the WEY VV6 electronic gear lever?

WEY VV6 electronic gear lever operation method is as follows: 1. When the ignition switch is in ON mode and the engine is not started, gear shifting is only possible between N (Neutral) and P (Park) positions. When the vehicle speed is below 2 km/h, opening the driver's door or turning off the engine will automatically shift the vehicle to P position. 2. Engaging P position: When the vehicle is stationary, press the parking gear button. (To avoid vehicle damage or accidents, ensure the vehicle is completely stopped before shifting to P or R positions.) Always depress the brake pedal before starting the vehicle, otherwise the vehicle may move automatically if the gear lever is in a driving position. 3. Briefly push the gear lever in the desired direction, surpassing the pressure point if necessary, then release it to automatically return to the center position. To disengage P position or engage R (Reverse) position, depress the brake pedal and press the unlock button; to engage D (Drive) position, depress the brake pedal. 4. After engaging D position, pulling the gear lever backward switches to M (Manual) position; pulling it backward again switches back to D position. The currently engaged gear will be displayed on both the gear lever and the instrument information center.

What are the precautions for making a left turn while driving?

Precautions for making a left turn in a vehicle are as follows: 1. Try to make the turn as wide as possible to avoid obstruction or collision with other hazards. 2. Check the rearview mirror while turning to ensure there are no vehicles or pedestrians behind or to the side. 3. Be aware of blind spots during the turn to avoid hitting the curb or causing a scrape. Before turning, always check for obstacles below the rearview mirror; if necessary, open the door to take a look before proceeding. 4. Maintain control of the steering wheel. Proper steering control is crucial when turning. For a tight turn, turn the steering wheel as much as possible and gradually straighten it after completing the turn; for a wide turn, steer slowly.

Should You Use Internal or External Air Circulation When Turning on the AC?

The best practice when turning on the AC is to alternate between internal and external air circulation. Although using internal circulation in summer is more fuel-efficient and provides the best cooling effect, prolonged use can lead to "air conditioning sickness," especially when idling in the car with the AC on, which may cause carbon monoxide poisoning. Below is an introduction to the two air circulation modes: 1. Internal circulation: The air blown by the blower circulates only inside the car. Since no external air is involved, internal circulation is fuel-efficient and cools (or heats) quickly, but the downside is that it hinders air renewal inside the car. 2. External circulation: The blower draws air from outside the car and blows it inside. The advantage is that external circulation maintains fresh air inside the car, but it consumes more fuel and cools (or heats) more slowly.

What Are the Effects of Overfilling Engine Oil?

Overfilling engine oil can have the following specific effects on a vehicle: 1. Oil may enter the combustion chamber through the gap between the cylinder and piston, leading to carbon buildup. 2. It increases the stirring resistance of the crankshaft and connecting rod, resulting in higher fuel consumption. 3. It may cause oil leakage. Below are some key points about adding engine oil: 1. Adding too little oil can reduce lubrication effectiveness, leading to severe engine wear and potentially causing cylinder scuffing; it may even shorten the engine's lifespan. 2. To maintain the lubrication system, the most important step is to regularly change the engine oil; it is best not to simply add oil. If oil is added frequently over time, it can lead to excessive buildup of sludge and carbon deposits inside the engine, clogging the oil pickup screen and preventing proper lubrication of engine components, which can severely damage engine parts.

What Causes Difficulty in Starting a Car?

The reasons for difficulty in starting a car are as follows: 1. Weak spark plug ignition energy: Not replacing spark plugs after their maintenance cycle can lead to a severe drop in ignition energy, making the car hard to start. 2. Severe carbon buildup in the car: Excessive carbon deposits inside the engine can cause the fuel injectors to spray gasoline that gets largely absorbed by the carbon deposits, resulting in difficulty starting. 3. Insufficient battery power: Low battery power reduces engine power, making it difficult to start the vehicle. 4. Clogged exhaust pipe: A clogged exhaust pipe leads to an overly lean air-fuel mixture during startup, causing difficulty in starting the car. 5. Faulty fuel pressure regulator: The fuel system's pressure directly affects the air-fuel mixture concentration. If the car is hard to start, the fuel pressure should be checked first, and the fault location can be determined by inspecting the fuel pressure regulator. 6. Incorrect engine timing: Incorrect engine timing can prevent the car from starting.

Does the Engine Hood Affect Heat Dissipation?

The engine hood does not affect the heat dissipation of the engine. The engine hood, also known as the engine cover, primarily serves an aesthetic purpose and therefore does not significantly impact the engine's performance. Engine heat dissipation mainly involves two processes. One is the water-cooling circulation system, where the water pump drives the circulation of coolant in the engine water jacket, pipes, and radiator to dissipate the heat generated during engine operation, keeping the engine temperature within the allowable range. The other is the engine compartment cooling system, where the heat generated during engine operation is mainly dissipated to the outside through the radiator and the engine body. In theory, the engine hood also plays a certain role in heat dissipation. Since the engine hood is made of special materials, if it cannot dissipate heat in time during engine operation, the high temperature generated by the engine can cause the paint on the hood to crack and peel quickly, affecting the aesthetics of the engine compartment.
