How often should a car be started?

It is generally recommended to start the car once a week and let it idle for a few minutes. When a car is not started for a long time, most of the lubricating oil adhering to the parts that should be lubricated will flow back to the oil pan under the influence of gravity, reducing the lubrication effect on various moving parts. Without the protection of an oil film, metal is prone to react with oxygen to form an oxide film, increasing friction and making it difficult to start. When the battery does not receive a charge for a long time, the sulfation process of the battery plates accelerates, increasing the internal resistance of the battery and reducing its lifespan. Due to the self-discharge effect of the battery, the terminal voltage may drop below 85%, causing irreversible damage to the battery. After the car is turned off, the battery still supplies power to the vehicle. It continuously provides power to the car's computer, TV, and circuit boards. Once the car is started, the alternator begins to work, replenishing the battery's charge. Starting the car once a week ensures the battery does not run into issues due to power depletion. If the car is not started for more than a month, it is advisable to disconnect the negative terminal of the car battery.

What Are the Functions of Driving Assistance?

Driving assistance consists of lane keeping assist, automatic parking assist, brake assist, reverse assist, and driving assist functions. Below is an introduction to the driving assistance system: 1. Lane keeping assist provides support for maintaining the lane while driving. It uses a camera to identify the lane markings. 2. In automatic parking assist, the reverse system mainly includes reverse radar and reverse camera, which alert the driver through warning sounds or visual rear conditions, enabling proactive avoidance to reduce accident damage. 3. Brake assist: Sensors determine whether to initiate emergency braking by analyzing the driver's pedal operation. The system can immediately apply maximum braking pressure to achieve the highest possible braking effect. 4. The reverse assist system uses ultrasonic and machine vision as detection methods for fully intelligent parking. 5. The driving assist function features ultra-strong anti-shake cameras for clearer images. To meet the requirements of mobile operation, all internal hardware and connectors are vibration-proof and reinforced.

What are the left-side function buttons on the Lynk & Co 01 steering wheel?

The left-side function buttons on the Lynk & Co 01 steering wheel are for the adaptive cruise control feature. This is a multifunction steering wheel primarily designed for urban traffic congestion, allowing drivers to avoid constantly pressing the brake pedal. During follow-the-car mode, it can automatically adjust to an appropriate speed based on the vehicle ahead and maintain a preset following distance. Relevant information about the adaptive cruise control system is as follows: 1. The greatest advantage of the adaptive cruise control system is that it can not only maintain the driver's preset speed but also reduce speed as needed under specific driving conditions, even automatically applying the brakes. 2. The adaptive cruise control system generally activates when the speed exceeds 25 km/h. When the speed drops below 25 km/h, manual control by the driver is required. Through system software upgrades, the adaptive cruise control system can achieve stop/start functionality.

How to Replace the Battery in a Car Remote?

Here are the steps to replace the battery in a car remote: 1. If the car remote key has a protective cover and key ring, remove them first. 2. Turn the key sideways, insert a flathead screwdriver into the gap, and apply upward force to partially lift the back cover. 3. Move the screwdriver along the gap to both sides, gradually expanding the gap and fully lifting the back cover. 4. Use your hand to pry the back cover open in the direction of the opening and remove it. 5. On one side of the battery, you will see a protruding clip. Press the battery at the clip part, and the battery will pop up. Then slide the battery out to remove it. 6. Prepare a new battery, ensuring it is the same model as the original one. 7. Insert the new battery into the car remote key in the reverse order of removal, paying attention to the positive and negative poles to avoid incorrect installation. 8. Align the back cover with the car remote key, place it down from the top, and press slightly downward until you hear a clicking sound, ensuring the back cover is fully secured.

What is the best engine oil for Geely Boyue?

Geely Boyue uses 5W-40 engine oil, and the official recommendation is Shell semi-synthetic oil. Below are detailed specifications for engine oil usage in Geely Boyue: 1. Currently, Geely Boyue is equipped with two powertrains: JLD-4G20 and JLE-4G18TD. 2. For JLD-4G20 engine: SAE5W-30 oil; API quality grade: SL or higher. For JLE-4G18TD engine: SAE5W-40 oil; API quality grade: SN or higher. 3. Taking 0W-20 as an example: The "0W" in 0W-20 indicates the cold-start performance of the oil. Oil with a lower number before the W can start the engine more easily in cold weather. The "20" indicates the oil's viscosity characteristics at high temperatures. 3. High-viscosity oils (with higher values) may be more suitable for high-speed driving or heavy-load vehicles. If SAE 10W-30 or higher viscosity oil is used in cold weather, the engine may be difficult to start. 4. It is recommended to use SAE 0W-20, 5W-20, or 5W-30 engine oil. Relatively speaking, using 0W-20 oil can maximize fuel savings.

What are the effects of not changing engine oil for a long time?

If engine oil is not changed for a long time, it will cause the following effects: 1. As the oil's lifespan declines, its lubricating ability will also rapidly decrease, preventing the engine from receiving proper lubrication, leading to abnormal wear. 2. Metal debris cleaned by the oil cannot be expelled and will accumulate inside the engine, causing dirt to form a large amount of sludge. 3. The engine may also experience increased fuel consumption, reduced power, difficulty starting, abnormal shaking, and poor operation. Below are the functions of engine oil: 1. Lubrication: There are many moving friction surfaces inside the engine (e.g., piston and cylinder, crankshaft and crankshaft bearing, valve and valve guide, etc.). The role of engine oil is to establish an oil film between these friction surfaces to achieve lubrication and anti-wear effects. 2. Cleaning: The movement of engine components causes wear and produces metal debris. Engine oil continuously circulates inside the engine through the action of the oil pump and carries these metal debris back to the oil pan. 3. Cooling: The continuous circulation of engine oil inside the engine can carry away the heat generated by the engine and cool it through the oil cooler. (The cooling effect of engine oil is only auxiliary.) 4. Sealing: The oil film formed by engine oil on the surface of the engine cylinder wall and the inner surface of the valve guide can provide a sealing and leak-proof effect.
