cluster displayPractical hints Car care Index 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. Adjust the temperature settings in small 
increments.
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 159. 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 171 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.
If the vehicle interior has been heated by direct sunlight 
and is very hot, ventilate the interior (open door or 
windows for a short period) before driving off.
Dust filter
Nearly all dust particles and pollen are filtered out 
before outside air enters the passenger compartment 
through the air distribution system.
