Press the Mercedes-Benz one-touch start button to activate the engine. Locate and press the recirculation mode button to enable interior air recirculation. After a short period, the system will automatically switch back to fresh air mode. To deactivate this function while parked, simply press the recirculation button again.

The Mercedes-Benz air conditioning's recirculation feature is quite user-friendly. In my GLC, the controls are located on the center console's AC panel—look for the small car icon button: the illuminated circular arrow indicates recirculation mode, which cycles only cabin air for faster cooling on hot days and blocks outside odors; the inward-pointing arrow activates fresh air intake, ideal for defogging during rainy weather. I recommend using fresh air mode more often on highways for ventilation, switching to recirculation in traffic or hazy conditions—but avoid prolonged use to prevent stuffiness that compromises driving safety. Some Mercedes models feature an AUTO mode that intelligently toggles between modes; additional settings like timers or sensitivity can be adjusted via the touchscreen. Remember, proper usage preserves the AC system, extends its lifespan, and enhances driving comfort.
