Overview of climate control systems

Notes on climate control
An interior air filter in combination with the prefil-
ter in the engine compartment must always be
used so that the air conditioning system, pollution
level monitoring and the air filtration work cor-
rectly. Use filters recommended and approved by
Mercedes-Benz. Always have maintenance work
carried out at a qualified specialist workshop.
