The 'key' on a car refers to the situation where the key is not detected. The vehicle's dashboard displays 'key' when the onboard computer fails to detect the signal from the key remote. Solutions for when the vehicle dashboard displays 'key' are: 1. Press the lock and unlock buttons on the key; 2. Replace the key's battery. Precautions for using car keys include: 1. Avoid contact with magnetic objects; 2. Avoid exposure to high-temperature environments; 3. Avoid hanging them together with other keys or accessories; 4. If lost, promptly match a new key to prevent property loss; 5. Avoid placing spare keys inside the car; 6. Prevent smart keys from falling or being hit; 7. When replacing the key battery, ensure the battery model matches.

In our driver circles, the term 'key' on a car basically refers to the car key, whether it's the old-fashioned metal key or the now-popular remote or smart key. I've been driving for over ten years, and every day I have to insert the key into the ignition or press a button to start the engine—it mainly handles locking, unlocking, and starting the car. If it's a smart key, it can even enable keyless entry, automatically unlocking when you approach the car, which is super convenient. Sometimes, due to signal interference or a weak battery after long use, the key might malfunction, and then you have to quickly replace the battery or use a spare key. During regular car maintenance, I always check the key's condition to ensure it works properly and doesn’t delay my trips. Also, modifying car keys requires caution, as adding random devices can affect the anti-theft system. In short, the key is an essential tool before driving—without it, the car is like a locked toy.

What Should Be the Minimum Proportion of New Energy Vehicles?

New energy vehicles should account for no less than 80% of the total. Below is relevant information about new energy vehicles: 1. Introduction: These vehicles use unconventional automotive fuels as their power source, integrating advanced technologies in vehicle power control and driving systems to form automobiles with advanced technical principles, new technologies, and novel structures. 2. Hybrid: These models use traditional fuels and are equipped with an electric motor/engine to improve low-speed power output and fuel consumption. 3. Pure Electric: These are mainly electric-powered vehicles. Most of them directly use an electric motor for driving, while some have the motor installed in the engine compartment. Others use the wheels as the rotors for four electric motors, with the main challenge lying in power storage technology.

Where is the camshaft position sensor located on an Audi A4?

Audi A4's camshaft position sensor is located inside the cylinder. Below is relevant information: 1. Camshaft Position Sensor: The camshaft position sensor is a sensing device, also known as a synchronization signal sensor. It serves as a cylinder identification and positioning device, sending camshaft position signals to the ECU and functioning as the primary control signal for ignition. 2. Principle: The function of the camshaft position sensor is to collect position signals from the valve camshaft and input them to the ECU, enabling the ECU to identify cylinder 1's compression top dead center. This facilitates sequential fuel injection control, ignition timing control, and knock control.

What is the problem with obvious jerking when shifting into reverse gear?

Obvious jerking when shifting into reverse gear is caused by transmission issues, such as slipping friction plates. Here are the related causes and solutions: 1. Damage to the reverse gear synchronizer. Solution: Repair or replace the reverse gear synchronizer. 2. Damage to the reverse gear teeth, such as broken or missing teeth. Solution: Repair or replace the reverse gear teeth. 3. Damage to the reverse gear bearing, causing friction noise due to poor lubrication. Solution: Repair or replace the bearing. 4. Releasing the clutch too quickly. Try shifting at 3000 RPM to reduce jerking. When downshifting, wait for the RPM to drop before shifting.

What is the solution for Odyssey idle vibration?

Odyssey vibration causes and solutions are as follows: 1. Severe engine carbon deposits: The most common cause of car vibration is dirty throttle or excessive carbon buildup in fuel injectors. When there's too much carbon inside the engine, the gasoline sprayed by cold start injectors gets largely absorbed by carbon deposits, resulting in over-lean mixture during cold starts and making ignition difficult. The solution is to clean the fuel system and check if the idle speed motor has carbon buildup that needs cleaning. 2. Ignition system issues: Check the working condition of spark plugs, high-voltage wires and ignition coils. Poor ignition system performance or bad spark plug firing can also cause such faults. The solution is to check if spark plugs have excessive carbon buildup and replace them if necessary.

What is the optimal remaining battery level for charging new energy vehicles?

According to Tesla's battery curve analysis, maintaining a charge/discharge range between 25%-75% is considered relatively reasonable. Of course, to alleviate range anxiety, most users opt for a full charge when charging time permits. However, during routine charging, it's advisable to maintain a certain battery level before initiating the charging process. Below are some key points regarding charging practices for new energy vehicles: 1. Market research data from a leading domestic consulting firm indicates that most users choose to recharge only when their battery level drops below 20%, which aligns with real-world usage scenarios. 2. Completely depleting the battery is detrimental to its health. Therefore, it's recommended to initiate charging when approximately 15% of the battery remains, as excessively low battery levels can also be harmful.
