[SanArabella]

Tiguan L air conditioning heating steps: Locate the temperature control switch on the air conditioning control panel; Adjust the temperature to the highest setting to activate heating; Find the airflow control knob and select an appropriate fan speed. Note that you don't need to press the AC button when using the heating function, as the AC button is the cooling switch for the car's air conditioning system. The compressor does not need to operate during heating. The Tiguan L's air conditioning system utilizes engine heat for warming. During heating, high-temperature coolant from the engine flows through the heater core, while the blower forces air to pass through this core, allowing warm air to be discharged from the air vents.
