What’s the correct tire pressure?

I don’t understand why I got this tire pressure warning message. I thought the correct tire pressure is between 37-40psi.

Check the inside of your fuel door. There are at least two. One for normal load and one for max load. The correct tire pressure depends on the number of passengers and the amount of cargo in the car. Then adjust it to the correct one when the tires are cold and go into the settings to reset TPMS to the new pressure. TPMS doesn't have a "correct" pressure preprogrammed. You set it to what you want it to be based on the load.

37-40 psi.
Why am I getting the warning message?
Is this another MBUX bug?

All you need to do is go into Service | Tires and set your current pressure as the reference pressure. Whoever saved it before must have saved a different one. But make sure you do this when the tires are cold. The actual pressure increases as the tires heat up. The picture you posted in your first post when did you take that? Were the tires cold at that time or were you driving? You must check and adjust your tire pressure when the tires are cold, and then save the reference pressure at that time.

OP, you want to check the tire pressures on the fuel door when cold as forum member superswiss mentioned, the picture you shown us is the one on the door sill.

Easy to reset, thank you!
