Automatic climate control The system is always at operational readiness, except when manually switched off. The automatic climate control only operates with the engine running. The temperature selector should be left at the desired temperature setting. The temperature selected is reached as quickly as possible. The system will not heat or cool any quicker by setting a higher or lower temperature. The desired interior temperature and air distribution can be selected separately for the left and right side of the passenger compartment. The automatic climate control removes considerable moisture from the air during operation in the cooling mode. It is normal for water to drip on the ground through ducts in the underbody. The air conditioning will not engage (no cooling) if the economy mode S is selected, see page 155. 1 Temperature, left 2 Temperature, right 3 Air volume 4 Automatic mode is selected Automatic climate control Instruments and controls Operation Driving 149 Instrument cluster display Practical hints Car care Technical data Index
