First, turn on the air volume button, which has 4 levels.
Then turn the temperature knob left towards the red zone. The lower you turn it, the hotter it gets.
Finally, select the air supply mode button on the right side of the air volume button. The last two settings are for blowing glass (one of which is under the feet and the glass at the same time) for. prevent the glass from breathing in winter. Note that this equipment cannot be circulated internally!
Here's the important point: don't press the A/C (air conditioning) button, because once it turns on, the air conditioner will run, wasting fuel. In winter, there is no need to turn on the air conditioner. The circulating air that cools the working fluid can fully meet the heating needs)
The internal circulation button is located next to the air conditioning. he isrecommended to circulate the air when in a city traffic jam. Yes, the second thing is that it's hot and won't bring in the exhaust from outside the car.
