How to Turn on the Heating in Audi A4 Air Conditioning?

[LaCarson]

Audi A4 air conditioning heating activation method: 1. After starting the car, wait approximately 8-15 minutes for the water temperature to reach normal operating temperature, then you can turn on the heating. 2. Adjust the air conditioning circulation mode to internal circulation and switch to heating mode. 3. Do not turn on the AC switch because the heating system utilizes the car's own heat cycle, which saves energy. 4. Adjust the air conditioning level to a suitable setting and direct the air vents. Additional information: 1. During the use of heating, it is not advisable to turn on the heating immediately after entering the car. When the car is in a cold start state, the engine's water temperature is very low. Turning on the heating in this state will not only fail to raise the temperature quickly but will also slow down the warming process and increase the engine's burden. 2. The correct approach is to warm up the car first. Wait until the temperature gauge reaches the middle position before using the heating, and set the air circulation to external circulation initially. After a while, switch to internal circulation to rapidly increase the temperature inside the car.
