Climate control The system is always at operational readiness, except when manually switched off. The 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 can be selected separately for the left and right side of the passenger compartment. The 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 145. Notes: Do not obstruct the air flow by placing objects on the air flow-through exhaust slots below the rear window. Also keep the air intake grill in front of the windshield free of snow and debris. The storage compartment between the front seats can be ventilated. See page 158 for notes on ventilating the storage space under the armrest in the center console. The air conditioner switches itself off for its own protection if refrigerant is lost. No cooling will then take place. Economy mode S cannot be switched off. Have the air conditioner checked by a Mercedes-Benz Center should this happen. Dust filter Nearly all dust particles and pollen are filtered out before outside air enters the passenger compartment through the air distribution system.
