Overview of climate control systems
Notes on climate control
An interior air lter in combination with the prel-
ter in the engine compartment must always be
used so that the air conditioning system, pollution
level monitoring and the air ltration work cor-
rectly. Use lters recommended and approved by
Mercedes-Benz. Always have maintenance work
carried out at a qualied specialist workshop.
