Overview of climate control systems
Notes on climate control
An interior air filter in combination with the pre‐
filter in the engine compartment must always be
used so that the air conditioning system, pollu‐
tion level monitoring and the air filtration work
correctly. Make sure that the filter is installed
correctly and the filter housing in the engine
compartment is closed correctly using the cap
and always tightly sealed when in operation. Use
filters recommended and approved by
Mercedes-Benz. Always have service work car‐
ried out at a qualified specialist workshop.
