I doubt if we got them but take the Glove box out and have a looksee
I'd be very surprised if you find one though.
Are you looking at the right thing, whats 30,000klm got to do with AC Air Filter, if you had one would need to be cleaned say monthly when you use your AC 30,000klm is not a gauge of when an air filter should be cleaned
They may mean System Gas Filter/Drier but we dont have that either.
