Which Button to Press for Car Heater?

Heater switch is generally displayed as a "thermometer" symbol or marked with red-blue color indicators on both sides. Rotating the knob towards the red zone gradually increases temperature. For automatic air conditioning systems, you can set a desired temperature and then press the "AUTO" button, allowing the system to automatically adjust based on the cabin temperature. Precautions for using car heaters are as follows: 1. Avoid directing warm air straight at the head, as prolonged exposure may cause driver fatigue and compromise driving safety. It is recommended to slightly open a window for air circulation during extended heater use to maintain oxygen levels and keep the driver alert. 2. When the heater is on, the enclosed cabin space creates an ideal environment for bacterial growth and transmission. If someone smokes in the car, nicotine and amines from the smoke will adhere to the evaporator surface. Under infrequent AC usage or humid conditions, bacteria can proliferate on the evaporator, causing air pollution when the AC is reactivated.
