Is a Paper Insurance Policy Mandatory for Annual Vehicle Inspection?

When undergoing annual vehicle inspection, an insurance policy is required. In regions where electronic insurance policies are implemented, there is no need to carry a paper policy as the inspection authority can verify the vehicle's electronic insurance policy. Introduction to Annual Inspection: Before the inspection, ensure the vehicle's braking performance is optimal—replace brake pads if necessary. Braking performance is one of the most critical safety indicators and a mandatory check during the inspection. Prior to the inspection, conduct a thorough check of the braking system. Pay special attention to brake fluid and brake pads. Dirty or moisture-contaminated brake fluid may cause soft braking, while excessively worn brake pads can lead to reduced braking force and unusual noises. Address any issues through maintenance to ensure your vehicle passes the inspection smoothly. Inspection Pass: You may apply for the inspection pass mark at the vehicle registration authority up to three months before the expiration of the current inspection period. Before applying, the vehicle owner must resolve all traffic violations and accidents related to the vehicle. During the application, the owner must complete an application form and submit the vehicle's license, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or exemption proof, and the vehicle safety technical inspection pass certificate.

How to reset the tire pressure on a Mercedes-Benz C200L?

Method to reset the tire pressure on a Mercedes-Benz C200: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button. After hearing a "dong" sound, release the button. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system will usually alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, a tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to remain on. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, such as by hitting the tire, it will also cause the tire pressure warning light to illuminate. For sensor damage issues, the only solution is to replace it with a new part.

What does the semicircular arrow on the remote car key represent?

The semicircular arrow on the remote car key represents starting the engine. When outside the car, first press the lock button, then hold the engine start button for more than three seconds to start the car. Typically, a remote car key has four buttons with the following functions: unlock, lock, open trunk, and locate car. Unlock button: Pressing the unlock button once only opens the driver's door; pressing it twice unlocks all four doors. Holding down the unlock button for several seconds will simultaneously open all four windows. On some models, the sunroof will also open. Lock button: Pressing it locks all four doors. It also has a hidden feature: remote window closing. Trunk release button: The car key has a button to open the trunk. Long-pressing the trunk release button (or pressing it twice on some models) will automatically pop open the trunk. Locate car button: Some car keys have a red button with a horn symbol or the word "Panic." This button is technically called the "locate car button."

Can Motorcycles Use Automotive Full Synthetic Oil?

Motorcycles can use automotive full synthetic oil. Here are some precautions regarding oil filling: Do not exceed the upper mark on the dipstick: Otherwise, excessive oil in the oil pan may enter the combustion chamber, causing the exhaust pipe to emit blue smoke. This not only increases fuel consumption but also leads to the accumulation of unburned or incompletely burned oil on the piston top and valves, creating a large amount of carbon deposits. This accelerates component wear and reduces engine power. Oil quantity should not be too low either: Especially when the oil level is below the dipstick mark, if not replenished in time, situations like climbing a slope, crossing a bump, or sudden braking may cause the oil pickup to expose the oil surface, leading to severe accidents such as cylinder seizure. This not only affects driving safety but also significantly shortens the lifespan of components. New and old oil should not be mixed: Because old oil contains substances with strong oxidation capabilities, which can accelerate the oxidation and deterioration of new oil, shorten its service life, and cause the loss of lubrication performance. This results in increased component wear and a shortened lifespan.
