AC button in a car refers to the air conditioning switch. AC is the abbreviation for Aircondition, and the A/C switch is essentially the air conditioning switch, which controls whether the compressor operates. More information about car air conditioning is as follows: 1. There is an electromagnetically controlled clutch inside the compressor. When its coil is energized, the electromagnetic clutch engages, and the compressor operates. Otherwise, the compressor's pulley just spins idly, and the compressor does not work. 2. If the light on this button is on, it indicates that the air conditioning is working, meaning that the compressor operates only when this button is pressed, and the air blown by the blower will be cold. For example, during hot summer days when you need to lower the temperature inside the car, press this button and turn the temperature selector switch to the blue part, and cold air will start blowing.

What does the yellow wrench on the dashboard mean?

The yellow wrench in a car is a maintenance indicator. When the yellow wrench appears on the dashboard, it serves as a reminder for the driver to perform timely maintenance on the vehicle. This icon needs to be manually reset after each maintenance service. If forgotten, the icon will continue to display even after maintenance has been performed. Not all vehicles display the small wrench symbol; some may show a yellow oil can icon instead, which similarly indicates that the car requires maintenance. When the yellow wrench light comes on, the owner should take the car to a 4S dealership for maintenance. Different car manufacturers set varying maintenance intervals for their models, so it's best to refer to the vehicle's user manual for specific guidance. After maintenance is completed, there is a reset procedure that needs to be followed to turn off the maintenance light. Maintenance mileage reminder cycle: The maintenance cycle is preset when the vehicle leaves the factory, so the "small wrench" will appear at certain mileage intervals to remind the driver to perform maintenance. Typically, the maintenance cycle is every 5,000–8,000 kilometers driven, though the factory-set interval is usually slightly longer than 8,000 kilometers.

Does high temperature in the car affect cigarettes left inside?

Cigarettes stored in a car are sensitive to high temperatures, as their shelf life is closely related to storage conditions. Cigarettes are highly susceptible to changes in environmental conditions and temperature. Prolonged exposure to high temperatures can cause them to deteriorate and develop an off taste. Below is an introduction to cooling down a car's interior: 1. Overview: Car interior cooling refers to measures taken during summer when the vehicle is exposed to direct sunlight, causing the interior temperature to rise significantly. In scorching summer heat, leaving a car parked outdoors for just half an hour can turn the cabin into a furnace with temperatures exceeding 60°C (140°F). Upon entering, the intense heat makes it unbearable to sit directly on the seats and may even lead to skin conditions like rashes or hemorrhoids. 2. Tips: When adding coolant, always pour it into the overflow tank. Never open the radiator cap while the engine is hot, as boiling water may gush out.

What is the ground clearance of the Trumpchi M8?

The ground clearance of the Trumpchi GM8 is 150mm. Smaller ground clearance: The smaller the ground clearance, the worse the ability to overcome obstacles. Regarding the minimum ground clearance, in previous standards, there was a strict requirement for the minimum ground clearance, approximately between 150-160mm, but this requirement has been removed in the current standards. Larger ground clearance: For sedans, the larger the ground clearance (exceeding 130mm), the better the off-road performance, but the worse the high-speed stability; the smaller the ground clearance (below 110mm), the better the high-speed stability, but the worse the off-road performance. If you frequently drive on mountain roads, choose a car with higher ground clearance. If you mainly drive on city roads or highways, a car with lower ground clearance is sufficient.
