I'm on the road with my 2008 535xi. Got a message that the RF tire was low. I've corrected the problem, but can't cancel the warning message. I don't have my owner's manual with me. How do I reset it? I have to say, I hate this car more than any vehicle I've ever owned. I bought it because I was enthralled with the way the drive train works. Great power, transmission shifts crisp and sure, good brakes - it's like a sports car that's big and comfy for long trips (which I do a lot). I thought I would get used to the idiotic controls, but it's been a year and I haven't. It is so frustrating to be driving a car that is so capable and have to divide my attention between driving it and screwing around with the idiotic controls they saddled it with. The car is a real tragedy. It would be a fantastic car if they gutted the interior and let to the folks at Mercedes redesign the interior and controls.
