THERMATIC automatic climate control ensures there's always a pleasant atmosphere in the CLS-Class, whatever the weather. THERMOTRONIC 4-zone automatic climate control, standard equipped in China for both
CLS 350 and CLS 500, offers additional comfort.

THERMOTRONIC has an additional control unit with display in the rear, enabling driver and passengers to configure their own preferred temperature settings in all four zones. Sensors monitor both the interior temperature and the intensity of the sunlight in all four zones so that the settings can be maintained automatically. A combined filter also improves the air-intake quality. If the outside air quality is poor, the ventilation flaps close automatically.
