Notes on climate control
An interior air "Nlter in combination with the pre"Nl-
ter in the engine compartment must always be
used so that the air conditioning system, pollution level monitoring and the air "Nltration work cor-
rectly. Use "Nlters recommended and approved by
Mercedes-Benz. Always have maintenance work
carried out at a quali"Ned specialist workshop.
