It is necessary to turn off the AC before turning off the car engine. Forgetting to turn off the air conditioning when the engine is off will consume battery power. If not turned off before shutting down the engine, the AC will automatically start the next time the car is turned on, which will place a heavier burden on the battery and cause wear and tear. Additional Information: Principle: The air conditioning system involves the compressor and blower, and the audio system is also a high-power electrical device. If not turned off before shutting down the engine, these systems will automatically start the next time the car is turned on, placing a heavier burden on the battery and causing wear and tear. This is especially true if the car's audio system has been modified, as the usual power consumption increases, and the impact on the battery during startup becomes even greater. Therefore, whether it's a temporary stop or a long-term parking, the air conditioning and audio systems should be turned off before shutting down the engine. Battery Maintenance: Car owners should pay attention to the usage of the car battery, frequently inspecting and maintaining it. With the changing driving habits nowadays, the number of electrical devices in cars is increasing, putting more and more pressure on the car battery. Without careful inspection and maintenance, the car battery can easily malfunction. Therefore, car owners must strengthen the inspection and maintenance of the car battery to avoid malfunctions caused by battery issues, which could bring trouble to driving.
