GLC43 tire pressure warning at 36PSI

Got an unexpected tire pressure warning today at 36PSI. Fuel door recommends at least 33PSI, which is cold pressure while the 36PSI is warm.

I will add a few PSI, but I was surprised that it would alert me now because it’s definitely been below 36PSI before with no alerts.

Once you set the proper tire pressure per sticker inside of the fuel door for your typical load scenario (that should be normal load for most of your driving), you have to go into the service menu in the digital instrument cluster and reset the tire pressure system to store your current pressure as the reference values. Most likely your dealer inflated the tires to the max load pressure on the door sticker and then set TPMS for that.
