How to Replace the Cabin Filter on a Smart?

Model: Smart Smart 451 - Years 2007-2015
Part: Cabin air filter

To replace the cabin filter on a Smart, start by removing the carpet in the lower footwell on the driver's side: once the carpet is removed, you will locate the cover of the filter box, which needs to be detached to access the underlying cabin filter. After removing the old filter, insert the new one: you can then close the box by repositioning the cover and the carpet, ensuring everything functions correctly.
