Tire Pressure Warning Light
I have a 2012 E350 Sport. My pressure warning light is RELENTLESS. I understand the importance of this safety feature but is this an indication of a true problem? I've been to the MB dealer twice about this, but if the car is running absolutely fine, the pressure is off because of the weather(???), is it necessary that I have to drive around with a warning light on all the time? Short of my buying an air pump and keeping it in my garage, does anyone have a solution? Thanks.

Somewhere in the settings for the tire pressure setting display between the speedometer and tachometer there is a way to reset the point where the tire pressure alert goes on. Yours is probably set much too high (as mine was). I forget where it was, but if you hunt around using the buttons on the steering wheel, you'll find it.

Hey,
This is a video for you to learn how to reset TMPS
BTW, I see such a warning message regarding tire pressures but not that symbol between 6 and 7 K RPM
I added some air today at the left rear tire , do not ignore such messages

In Operator's Manual
There is a section in the Operator's Manual on the TPMS indicators and warning lights and how to set the TP level.
The only time mine came on is the first time they rotated the tires (Luxury model) and the tech forgot to adjust the tires.
Bottom line, once you set the TPMS levels, it should never come on unless you have a problem. Not sure, but I think they have to be about 10 lbs. low for warning light to come on.
