Notes on climate control
For the air-conditioning system, pollution level
monitoring and air filtration to function correctly,
an interior air filter must always be used. Make
sure that the filter is installed correctly. Use filters
recommended and approved by Mercedes-Benz.
Always have maintenance work carried out at a
qualified specialist workshop.
