What do the gears M+ and M- mean?

Gears M+ and M- refer to the manual mode of an automatic transmission vehicle. In this gear mode, shifting can be done like a manual transmission car, shifting up at high speeds and down at low speeds. Pushing the gear lever to M+ means shifting up one gear, while pushing it to M- means shifting down one gear. Advantages of a manual-automatic transmission car: 1. Faster braking and stopping: When the vehicle is driving at high speed and needs to brake urgently, using the manual method to downshift can slow the vehicle down as quickly as possible. This is easier to master and operate with a manual transmission car, allowing the vehicle to brake and stop faster. 2. Easier exit from turns: Faster cornering. Usually when cornering, you first step on the brake to slow down before entering the turn, then step on the accelerator when about to exit the turn to quickly leave the turn. If you switch to "manual-automatic" mode before entering the turn and downshift to use the engine's traction to control the speed, you can smoothly and safely exit the turn with just a light press on the accelerator when preparing to exit. 3. Reduced brake pad wear: When going downhill, if an automatic transmission car chooses to coast in neutral, it not only harms the car but is also unsafe. If you choose manual mode and use first gear to pull the vehicle, you don't need to keep stepping on the brake, thus reducing wear on the brake pads.

What does 20W-50 motor oil mean?

20W-50 is a specification for motor oil, where 20W indicates that the oil can function normally at temperatures as low as -15 degrees Celsius. The 'W' stands for WINTER, and the number before 'W' represents the oil's flow performance at low temperatures—the smaller the number, the better the starting performance in cold conditions. The number 50 represents the oil's viscosity and flow characteristics, meaning the number after 'W' indicates the oil's stability at high temperatures (i.e., its resistance to thinning). A higher number signifies better high-temperature stability. Functions of motor oil: Motor oil lubricates the engine to reduce friction, aids in cooling, provides sealing to prevent leaks, protects against rust and corrosion, and acts as a shock absorber. It is often referred to as the 'blood' of a car. Choosing the right oil and changing it regularly helps maintain the engine in good condition and extends its lifespan. Selecting motor oil: When choosing motor oil, the most expensive option isn't necessarily the best. Instead, the correct approach is to select oil based on the characteristics of the car's engine and the driver's habits. Oil can be categorized by its suitability for winter or summer use. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, an oil with excellent low-temperature viscosity performance is not required.

What Are the Reasons Why the Passenger Door Won't Open?

Introduction to the reasons why the passenger door won't open: Central locking system is activated: When the door won't open, you can first use the car key to unlock and then lock it again, repeating this twice. Then locate the central locking button on the left front door trim of the driver's side and press the unlock button. Try opening the stuck door again to see if it works. This is one of the reasons why a door might not open. Child lock is activated: When closing the door, always check if the child lock is turned off. If the door won't open, use a flathead screwdriver to turn the child lock to the off position. Door lock cable malfunction: When this issue occurs, the door cannot be opened from the inside because the malfunctioning cable directly affects the lock mechanism. Door hinges or lock post deformation: After the door is subjected to external force, the hinges or lock post may become deformed, which is another reason why the door might not open. Door limiter failure: When this problem occurs, opening the door becomes very difficult or impossible. The solution is to replace the door limiter with a new one to restore smooth operation. Door frozen: In winter, cold weather can easily freeze the door. Sometimes even the door lock mechanism freezes, making the door impossible to open. To fix this, park the car in sunlight or use a heat lamp to thaw the frozen door.

What Causes the Wuling Zhiguang's Radiator to Frequently Boil Over?

The frequent boiling over of the Wuling Zhiguang's radiator may be caused by several factors, including a faulty engine thermostat that fails to open, insufficient coolant, a malfunctioning engine water pump, a clogged radiator, or a non-functioning cooling fan. It is recommended to visit a 4S shop or an auto repair shop to diagnose the specific issue. The detailed reasons are as follows: Reduced Heat Exchange Efficiency: Issues such as a damaged thermostat, a faulty electric fan, or low coolant levels in the cooling system can prevent the coolant in the radiator from cooling down, leading to a rise in water temperature. When the boiling point of water is reached, a large number of bubbles form, occupying part of the radiator's surface area. This results in severe coolant depletion around the cylinder walls, even if there is still coolant in the radiator. Without sufficient coolant around the cylinder walls to dissipate heat, heat exchange efficiency is significantly reduced, making it impossible to transfer heat from the cylinders to the radiator. High-Load Driving: When the temperature inside the cylinders rises rapidly, continued high-load driving without timely heat dissipation can weaken components such as pistons, piston rings, and connecting rods, potentially causing deformation. These parts may then fail to withstand normal loads, and the normal gaps between components can be disrupted, preventing the formation of proper oil films. In mild cases, this can lead to engine cylinder or bearing damage; in severe cases, the entire engine may be damaged or even rendered unusable.

Can someone else take the penalty points for a DiDi operating vehicle's traffic violation?

No, having someone else take the penalty points is illegal. When capturing traffic violations, not only the vehicle but also the driver is photographed. When handling the violation, the driver must present their own driver's license. The staff will strictly check whether the person clearing the points is the one who committed the violation at the time. Only after confirming that the person is the violator and that there are no issues with the driver's license and vehicle registration will the penalty points be processed. Additional information: 1. If the penalty points do not reach 12 in a scoring cycle: If the driver's penalty points in a scoring cycle do not reach 12 and the fines have been paid, the points will be cleared. If the points do not reach 12 but there are unpaid fines, the points will carry over to the next cycle. 2. If the accumulated points reach 12 in a scoring cycle: If a driver's accumulated points reach 12 in a scoring cycle, the public security traffic management department will confiscate their driver's license. The driver must report to the traffic management department of the public security authority where the driver's license was issued or where the violation occurred within 15 days to receive seven days of education on road traffic safety laws, regulations, and related knowledge, and must also take the subject one exam. 3. If the points reach 12 and the driver refuses to participate in the education: If a driver's points reach 12 and they refuse to participate in the education or take the exam as notified by the traffic management department of the public security authority, their driver's license will be suspended by the traffic management department of the public security authority.
