When the vehicle is in the off state, the engine is not working, so the vehicle's alternator is also not functioning. If the dash cam is turned on, it can only rely on the battery for power, which will consume the battery's charge. It is not recommended to use it this way for extended periods. More information about dash cams is as follows: 1. Power Supply from the Car: The dash cam's operating power is provided by the car, so it can only work when the car is running. Some dash cams have battery power, but the battery capacity is too small to support long-term operation. Connecting the dash cam directly to the car battery will cause the battery to discharge continuously, affecting its lifespan. It is recommended to switch to in-car monitoring devices that can maintain long-term recording, although the power supply issue inside the car remains troublesome. 2. Related Features: Most dash cams on the market now come with matching mobile apps. Through the app, you can set functions such as shutdown time after the car is off, audio and video recording, and more. You can also view dash cam playback in real time, but note that the dash cam will stop recording while playback is being viewed. The playback of the dash cam footage is crucial for determining fault in accidents and serves as the only evidence. It is advisable to lock accident footage for permanent storage. Different brands of dash cams offer varying features. Many dash cams now come with built-in G-sensors that automatically lock footage when sudden acceleration or deceleration exceeds a set threshold, preventing data loss.

After turning off the car, I recommend turning off the dash cam as well. With over 30 years of driving experience, I've seen plenty of troubles caused by small oversights. If the dash cam doesn't have an auto-shutdown feature, keeping it running after engine shut-off can drain the battery, especially for older cars with lead-acid batteries that already have limited lifespan. For short stops like buying cigarettes, the battery might hold up; but parking for hours or overnight could lead to deep discharge, potentially leaving you stranded with a dead battery - a real hassle. My dash cam has parking surveillance, but I've made it a habit to manually check the power switch after turning off the engine to ensure complete shutdown. This prevents emergency calls for jump-starts, saving both money and frustration. Developing this safety habit protects your battery and saves you money.

What Are the Symptoms of a Faulty Clutch?

When there is a problem with the clutch, the following symptoms may appear: 1. Clutch Slipping: Weak acceleration and reduced power performance. 2. Incomplete Clutch Disengagement: The relationship between the pressure plate and the friction disc is interdependent. When there is an issue with the friction disc, it accelerates the wear of the pressure plate and even the flywheel. The main manifestations include difficulty in shifting gears, incomplete disengagement, and shaking during startup. 3. Abnormal Clutch Noise: When the clutch pedal is slightly depressed, the inner end face of the release bearing just contacts the release lever, and the clutch immediately makes a continuous "click, click, click" noise; noise accompanied by shaking occurs during startup engagement or separation while driving. 4. Clutch Vibration: The entire vehicle shakes during startup, especially when idling, shifting into low gear, and gradually lifting the clutch pedal to start. The vehicle experiences continuous impacts.

What is the normal idle speed for a Chery A3?

Chery A3's normal idle speed is 850 rpm. Introduction to idle speed: Idle speed refers to an operating condition of a car. When the engine runs without load, it is called idling, meaning the car is in neutral gear. The engine speed during idling is called idle speed. The idle speed can be adjusted by modifying the throttle opening size, etc. Idling means the engine "produces power without doing work." Classification of idle speed: Normal idle: When the vehicle is in a parked state and the engine is started, the minimum stable operating speed of the engine is called parking idle (the process of the engine transitioning from a cold idle state to reaching the idle state at normal operating temperature is called warm-up or hot start); Driving idle: During gear shifting, if the accelerator pedal is not pressed or is released while driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed, which is referred to as driving idle.

What is the voltage of a Mercedes-Benz battery?

Mercedes-Benz battery voltage is 12V. Introduction to automotive batteries: Automotive batteries are an essential part of a vehicle and can be divided into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses a lead-calcium alloy as the grid frame, the amount of water decomposition during charging is minimal, and water evaporation is also low. Additionally, the sealed structure of the casing releases very little sulfuric acid gas. Compared to traditional batteries, it has the advantages of not requiring any liquid addition and having a long power storage time. Functions of the battery: When starting the engine, it provides a strong starting current (around 10A) to the engine; when the generator is overloaded, it can assist the generator in supplying power to electrical devices; when the engine is idling, it supplies power to electrical devices; the battery also acts as a large-capacity capacitor, protecting the vehicle's electrical appliances; when the generator's terminal voltage is higher than the electromotive force of the lead battery, it converts part of the electrical energy into chemical energy for storage, which is charging.

Should Nissan Sylphy use 0w20 or 5w30?

Nissan Sylphy can use either 0w20 or 5w30 engine oil. Introduction to 0w20 and 5w30 engine oils: The main difference lies in low-temperature fluidity. 0w40 has lower low-temperature fluidity than 5w40. The number 0 indicates that the oil can remain liquid at -40°C, and will solidify below -40°C; the number 5 indicates that the oil can remain liquid at -35°C, and will solidify below -35°C. Generally, 0w40 is used in northern regions, while 5w40 is mainly used in southern regions. Introduction to engine oil: The oil grade usually indicates viscosity and quality. The viscosity of lubricating oil is often identified using SAE grades, where SAE stands for the "Society of Automotive Engineers." The "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. The number after the "W" (after the hyphen) indicates the oil's high-temperature resistance, with a higher number meaning better protection at high temperatures.

Is It Dangerous for a Car to Run Over Glass Shards?

Tires generally won't be damaged if they run over glass shards. Jack up the wheel and rotate it to check—as long as the glass isn't embedded in the tire, there's no issue. Even if it is embedded, as long as there's no slow air leakage, it's fine. This is because the tread structure of car tires is quite robust, containing steel wires inside. Methods to handle a car tire running over glass: 1. Check for air leakage: First, inspect whether the tire has been punctured and is leaking air. If it is, replace it with the spare tire and take the punctured one for repair. 2. Inspect the tread: Examine the extent of damage to the tire tread, assessing the depth and width. If the car is moving at high speed and runs over a large piece of glass in a position where there happens to be a support point, the tire could be punctured and might even be rendered unusable. 3. Check the tire sidewall: The sidewall structure isn't as sturdy as the tread and is relatively weaker. If the glass cut is large and deep, the tire will need to be replaced.
