A FULLY automatic, thermostatically controlled climate system with microfilter is standard across the 5 Series range. The driver and front passenger can each choose their own airflow and fan intensity via the push-button controls. No less than 14 nozzles ensure draught-free supply of air. The microfilter is designed to remove pollen, dust, soot and the like from the air drawn into the passenger compartment. The filter has a large surface area to ensure optimum efficiency without limiting air feed.
