You should turn off the air conditioner before turning off the engine. Forgetting to turn off the air conditioner after shutting down the engine can be harmful to the engine. This is because, during the next vehicle startup, the engine will have to bear the additional load of the air conditioner, which may cause damage due to the high stress. Below are some additional misconceptions about parking and turning off the engine: 1. Listening to music after turning off the engine: After the engine is turned off, devices such as the radio, CD player, navigation system, lights, and other electrical appliances can still be used. However, prolonged use can lead to excessive battery discharge, which may shorten the battery's lifespan. 2. Forgetting to turn off the lights before turning off the engine: Many new car owners often make the mistake of forgetting to turn off interior lights when parking and shutting down the engine. Experts warn that the battery may be drained overnight, making it difficult to start the car the next day.
