Low tyre pressure question

[shakjav]

Hi,

Newbie here. My Mercedes c200 Sedan (year 2020) got a warning light for low tyre pressure. Mercedes Me app shows it as 285 kPa. But when I check the recommended amount inside the fuel cap it says it should be 250 kPa.

Am I reading this right? Why would it be low if the recommended is 250? Couple images attached.

Thanks.

Set the pressures to the cap, THEN reset the dash to the new pressures.

Thanks so get it down to 250 and reset?

Always check them and set them when cold. The onboard system simply checks pressures against what they actually are when they are reset so your front left was probably set higher which is why it is now giving you a warning.

Set the pressures to the cap, THEN reset the dash to the new pressures THEN ditch mercedes me app.

Corrected that for you

Corrected that for you

“THEN ditch mercedes me app.”

Why?
