Strange tire pressure alert
I got this alert.
the strange part is that there is both yellow and white color fonts. What do they mean? Also there is nothing wrong with the pressure. I even checked with a manual gauge. Anyone know what is going on?

Just guessing since the pic is broken, but i dont trust the digital gauge
i always use a manual one, and it generally never matches perfectly. The computer rounds up or down the PSI...
Whatever your psi is at, when you hit the 'reset TPS button' in the dash, it will warn you when the tires are within 3-5 psi of that number for each wheel.
So if each wheel is different by one or two, and u accidentrally or intnetionally set the TPS to remember those values, it will give you odd lights sometimes especially when the weathers changing and the PSi fluctuating

You need to inflate all four tires to the exact same psi. Then click the "reset TPMS" in COMAND. Assuming the TPMS has registered the values as the same values you got in the compressor/manual gauge, it will use those values as a benchmark and warn you whenever one of the tires deviate a certain percentage below. White = normal; Yellow = losing pressure; Orange/Red = low. So that would explain why some tires are listed as white and some are listed as yellow (because the individual tires' benchmark values were different to begin with).

Sometimes it takes doing it twice, but here it is.
Now what is strange in "correct pressure"?
Sounds like paranoia to me
