[LunaDella]

The temperature adjustment for the Mercedes-Benz E300L is located on the mechanical buttons of the center console. Functions like defogging and heating can be directly activated via these buttons. Defogging: There are two separate buttons for front windshield defogging and rear windshield defogging. Pressing the corresponding button will activate the defogging function. Heating: Simply increase the temperature to activate the heating function. When using the heating function, please turn off the A/C switch. This is because the air conditioning compressor is only engaged during cooling. The heating function utilizes the engine's coolant and the heat from the glass heating wires. Internal/External Air Circulation: Internal circulation heats or cools the air inside the car and recirculates it, while external circulation brings in outside air. Use internal circulation in congested areas or environments with poor air quality. On highways, it's advisable to periodically switch from internal to external circulation, with internal circulation ideally not exceeding one hour.
