The heater switch is usually displayed as a "thermometer" or marked with red and blue colors on both sides. By turning the knob, the red area indicates gradually increasing temperature. Here are the specific instructions for using the car heater in winter: 1. How to turn it on: First, start the engine for preheating. Wait until the engine temperature pointer reaches the middle position, then turn on the heater air conditioning. At the same time, set the air circulation to external circulation to expel the cold air from the car. After waiting for 2~3 minutes, set the air circulation to internal circulation. 2. Opening the window is necessary when using the heater for a long time: The warm air should not blow directly on the head, as prolonged exposure can cause driver fatigue and affect driving safety. Therefore, it is recommended to open the window slightly to allow air circulation when using the heater for an extended period. This ensures the oxygen level inside the car and keeps the driver alert.
