open up the Kilometer/mile display on the MFD then cycle inside that menu until you reach the tire pressure monitor then the screen will tell you to press + to reactivate the TPMS, so go ahead and press + and wait a few seconds then the MFD will tell you "TPMS Reactivated!" now please note the "!" because that's Mercedes's way of mocking us for the terrible way of resetting the system and making us second guess that its reset.

But first make sure it needs to be reset. The people who put your tires on may have simply inflated the tires to less than normal, and the system is simply telling you that. Resetting it does not simply turn off the light, it makes whatever pressure is in your tires at the moment the new normal. You don't want that. Inflate them correctly and then reset it.

Good point to check the pressure before resetting it. Did find the reset option in Tire Pressure page under Settings, and need to hold the reset button to trigger the reset.
