How to turn on the warm air in winter?

In winter, many car owners turn on the air conditioning heater as soon as the vehicle starts because they are afraid of the cold. In fact, because the engine has just started in winter and the temperature of the water tank is still very low, turning on the air conditioner can not only make the temperature inside the car rise rapidly, but also increase the burden on the engine and delay the normal rise of the engine temperature.

The correct way: Start the engine to warm up first. After the engine temperature indicator reaches the middle position, first turn on the warm air conditioner, and set the air circulation to external circulation, so that the cold air in the car can be discharged outside the car. After waiting for 2 to 3 minutes, set the air circulation to internal circulation.
