Will be going for the 5k tire rotation coupon in a couple weeks as I'm at 4700 miles right now (purchased car in August), but the check air filter screen keeps coming up when I switch the navigation. Any thoughts as to why that might be? I thought those are usually replaced around 30k miles.
I don't have nav, but do you have solar roof that may be why it might be telling you to check the cabin filter.
I agree with Troyroy. That's the first thing I'd check. No way the air filter should be dirty @ 4700 miles.
There have also been reports of mice making a home on the cabin filter! Some have even posted pictures. It might be worth checking! Also, 30k miles is a little high for replacing the cabin filter. I changed mine at 20k and it was full of dirt etc.
In the nav system, there is a maintenance section, where you can program reminders for various maintenance items, and the reminders are displayed on the nav screen (this is different than the oil/filter service reminder which is displayed on the dash display). It could be your dealer programs reminders as a "revenue enhancement" program.
Thanks for the suggestions guys =) Ill check the nav screen tomorrow morning, and the blockage is possible, although after today's snowstorm I know there is snow/ice in there, so maybe I'll wait a little bit til it thaws to check for sure.
