Overview of climate control systems
Notes on climate control
An interior air filter must always be used so that
the air conditioning system, pollution level moni‐
toring and the air filtering function work cor‐
rectly. Make sure that the filter is installed cor‐
rectly and the filter housing in the engine com‐
partment is closed correctly using the cap and
always tightly sealed when in operation. Use fil‐
ters recommended and approved by Mercedes-
Benz. Always have service work carried out at a
qualified specialist workshop.
