How to solve the low temperature of cars in winter?

The following is the solution to the low temperature inside the car in winter: 1, turn on the air conditioner heater. It is not advisable to turn on the warm air immediately after the car starts, and wait for about 3-5 minutes. After the engine temperature indicator reaches the central position, turn on the warm air conditioner, and ensure that the air circulation is set to external circulation, let the cold air inside the car sweep outside the car, wait for 2 minutes, and then set the air circulation to internal circulation, so that the temperature inside the car can rise rapidly. The suitable temperature of warm air is 20℃. 2. Choose car mats. Silicone pad and rubber pad are both good choices. These two kinds of foot pads have good cold resistance, low temperature resistance, no deformation at MINUS 10 degrees and easy cleaning. Be sure to try the new mat first after installing it. Step on the accelerator, brake and clutch pedal by hand to see if you can step on it to the end. 3. Put a warm cushion on it. Cushions are divided into pure wool and artificial wool. The wool cushion looks luxurious and comfortable, just like a fur coat. But the disadvantage is that it is not easy to clean.
