You can charge your phone, but it's best not to do so when the car is turned off. As long as the ignition is on, other electrical devices in the car will also remain powered, which can easily lead to battery drain or even failure to start the car over time, and may also cause damage to the battery. Here are some related points: 1. Automatic Power Cut: Some cars will automatically cut off all power a few minutes after the engine is turned off or the car is locked to protect the battery. For example, the BMW X1 has this feature. It's better to prepare a power bank for charging your phone rather than risking battery drain or damage to the car battery. The battery is simply "draining" when the car is off, which is not worth the trouble. 2. Other Devices Should Not Be Used: Not just phone charging, but other electrical devices should not be used for extended periods after the car is turned off, such as the air conditioning, multimedia system, headlights, and other external electrical devices. Try to avoid overloading the battery. Battery drain not only causes the inconvenience of being unable to start the car but can also lead to more serious damage to the battery.

Can I take the Subject 4 exam with just an ID card?

For Subject 4, you can take the exam with just an ID card. The Subject 4 exam consists of 50 questions, primarily presented in the form of case studies, images, and animations. The maximum score is 100, with a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Since this test is conducted after Subject 3, it is commonly called Subject 4, although officially there is no such designation as Subject 4. If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retest on your own, and no additional fees are required for the retest. There are no scheduling restrictions, but the driving skills test permit is valid for three years. If the applicant fails to complete the test within this period, the results of any passed subjects will become invalid.

How long can license plates be retained after vehicle scrapping?

After a vehicle is scrapped, the motor vehicle license plate can be applied for retention within 1 year, and the application can also be extended for an additional half year. This means car owners who are planning to purchase a new vehicle do not need to rush, nor do they have to worry, as sometimes waiting for a new car can take more than half a year.

What does the triangle exclamation mark in Haval H4 mean?

A triangle with an exclamation mark indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault warning in vehicles. Besides the triangle exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red parentheses and circle with an exclamation mark in the middle, a yellow parentheses with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark indicates an automatic transmission fault warning light, meaning there is a transmission issue or the transmission fluid level is below the normal range. The transmission fluid should be replaced promptly. Brake system fault: A parentheses and circle with an exclamation mark in the middle represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire pressure anomaly: A parentheses with a horizontal line and an exclamation mark in the middle indicates a tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is a lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

What oil can be used as a substitute for a jack?

A jack can temporarily use hydraulic oil as a substitute, but it should be replaced promptly. Flat base: When using a hydraulic jack, place a flat, sturdy, and oil-free wooden board underneath to expand the pressure-bearing surface and ensure safety. Do not use an iron plate instead of a wooden board to prevent slipping. Smooth start: Lift smoothly. After slightly raising the load, check for any abnormalities. If there are no issues, continue lifting. Do not arbitrarily lengthen the handle or operate too forcefully. Avoid overloading or exceeding height limits. When the piston rod shows a red line, it indicates that the rated height has been reached, and lifting should stop.
