When a Mercedes-Benz displays the 'check tire pressure' message, it means the tire pressure monitoring system is alerting you. The tire pressure monitoring indicator is a yellow symbol featuring an irregular circle without a seal on top, with four small spikes at the bottom and an exclamation mark inside. The illumination of this indicator signifies abnormal tire pressure. There are generally three reasons for abnormal tire pressure in a Mercedes-Benz: Abnormal tire pressure: The system typically alerts when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system retains the previous data, causing the tire pressure monitoring indicator to light up. 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 a curb, it can trigger the tire pressure warning light. In case of sensor damage, the only solution is to replace it with a new one.

What is the structure of an engine radiator?

Engine radiator structure consists of an inlet pipe and an outlet pipe. Introduction to engine radiator: The car radiator, also known as a heat exchanger, is a key component in the automobile cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. Working principle of the engine radiator: The radiator is a crucial component of a water-cooled engine. As a major part of the heat dissipation circuit in a water-cooled engine, it absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, the temperature rise after absorbing heat from the engine block is relatively small. Thus, the engine's heat is transferred through the liquid cooling circuit, using water as a heat carrier. The heat is then dissipated via large-area cooling fins through convection, maintaining the engine's optimal operating temperature.

How to Pass Through a Highway Toll Station?

When approaching a toll station, drivers should reduce speed in advance and select the appropriate lane beforehand. Below are relevant details: 1. ETC: It's best to choose a lane with a green light signal above and fewer vehicles to avoid sudden lane changes. When entering the toll station, vehicles should queue up in order without cutting in line. If you have an ETC card, you can opt for an ETC lane with fewer vehicles. 2. Precautions: When nearing the toll booth, position your vehicle close to it, aligning the driver's window with the toll window for smooth cash, ticket, or pass card transactions. After receiving the pass card or ticket, store it properly to avoid misplacement, which could cause delays when exiting the highway if the pass card or ticket cannot be found.

Is there a difference in highway tolls for yellow license plates and blue license plates?

There is a difference in highway tolls for yellow license plates and blue license plates. Generally, yellow license plates are charged more, while blue license plates are charged less. Small trucks under two tons usually have blue license plates. Conditions for obtaining a blue license plate: The vehicle length must be less than or equal to 6 meters; the registered tonnage must be less than or equal to 1.5 tons; the total mass must be less than or equal to 4.5 tons. Conditions for obtaining a yellow license plate: Yellow license plates require an operating permit and must undergo an annual inspection every quarter (i.e., every 3 months).
