The AC switch in a car air conditioner is the switch for the vehicle's air conditioning compressor. Here are some introductions about the car air conditioner: 1. AC switch: The A/C button in the car is the switch for the vehicle's air conditioning compressor, and its function is to control the on and off of the vehicle's compressor. The cold air for car air conditioning comes from the operation of the vehicle's air conditioning system, which requires the vehicle's compressor to work. When the A/C button is pressed, the air conditioner's compressor will operate, and the air blown out by the blower will be cold. 2. Home air conditioner: Unlike the heating method of home air conditioners, the heat source for car air conditioning heating comes from the engine's coolant. The coolant absorbs the heat from the engine and is blown into the car by the blower. Therefore, heating does not require turning on the air conditioning compressor.

It also delivers stronger performance during subsequent usage. You may consider this option based on your vehicle's actual conditions. Overall, if your car's operating costs don't require strict control, I recommend directly choosing 95-octane gasoline as it offers relatively better safety, comfort, reliability, and stability.

What Does the Turtle Warning Light Symbol Mean in New Energy Vehicles?

It indicates a malfunction in the vehicle's powertrain system. Here is some relevant information about new energy vehicles: 1. Advantages: The most notable advantage is significantly reduced pollution, as these vehicles achieve better energy efficiency and environmental protection since they don't rely on combustion engines and thus produce no exhaust emissions. They also offer pricing advantages with certain purchase subsidies available, helping buyers save on costs. Additionally, these vehicles operate with minimal noise, providing a comfortable driving experience. 2. Vehicle Classification: Pure electric vehicles can be registered with green license plates. Fuel hybrid vehicles belong to the conventional vehicle category and are not classified as new energy vehicles, thus ineligible for green plates. Plug-in hybrid vehicles qualify as new energy vehicles and can use green license plates. Range-extended hybrid vehicles are also eligible for green plates.
