The specific opening method is:
1. After the car is started, start the engine to warm up. When the engine temperature indicator reaches the middle (about 8 to 15 minutes later), the water temperature rises to the normal temperature, and the warm air can be turned on at this time.
2. Adjust the circulation mode of the air conditioner to in-vehicle circulation.
3. Switch to warm air mode.
4. Don't turn on the air conditioner.
5, air conditioning gear adjustment is suitable for gear, air outlet wind direction can be adjusted.
Precautions:
1. The heating function of the automobile air conditioner is provided by the heater box of the vehicle. If the air conditioner wants to blow out hot air, the premise is that the engine temperature must be in a hot state, otherwise the air conditioner will only blow out cold air. If warm air is used in winter, the wind direction should be adjusted to the position at the foot of the blower, so that good heating effect can be obtained.
You don't need to press the AC key before turning on the warm air. It is suggested to use the internal circulation after turning on the warm air, so that the temperature in the car will rise faster, and then switch to the external circulation after the temperature rises to ensure the air circulation in the car. When driving in winter, the warm air temperature should not be too high, so it is recommended to set the temperature inside the car at about 22 degrees.
It takes some time to turn on the warm air. The heater cannot be turned on immediately after the vehicle is started. It is necessary to let the engine slowly start to warm up. When the temperature reaches a certain value, it is best to turn on the warm air, so that the wind blown out of the air outlet is not cold air. The air volume needs to be adjusted well, neither too big nor too small, and it is best to adjust it at a medium air volume, and the effect will be better.
