TPMS

A couple of weeks ago low tire pressure message appeared - see attached photo. What is weird that the actual tire pressure is OK. When the temperature changes so does the tire pressure. Yet I am consistently getting this annoying message.
Any ideas what the issue is? I know I can drive 20 miles to the dealer

, but maybe there is a sort of reset I can do myself.
Thank

Try this:

Step-by-Step Reset Procedure
  1. Check and Adjust Tire Pressure:
    Before you begin the reset process, confirm that all your tires are inflated to the correct PSI, as indicated on the sticker inside your driver's side door. (Or set your own PSI settings)
  2. Turn On the Vehicle:
    Turn the ignition to the "On" position but do not start the engine.
  3. Access the Service Menu:
    Press the Home button on the left side of your steering wheel to bring up the main menu.
  4. Navigate to Tires:
    Scroll right on the steering wheel's touchpad until you reach the "Service" menu, then press the "OK" or "Enter" button to select it.
  5. Select Tire Pressure:
    Navigate down or across to the "Tire Pressure" option in the service menu and press "OK".
  6. Accept New Pressure:
    You will likely see an option to confirm or accept the current tire pressures as the new reference values.
  7. Drive to Calibrate:
    After selecting to accept the new pressure, the system will need to recalibrate. Drive the vehicle for a few minutes (around five minutes) at a moderate speed to complete the recalibration process, and the light should go off.

Thanks. Found this in manual and on YouTube. Now I need to lower the tire pressure to 32 psi before i proceed with the reset/restart. I normally run 35 PSI but the limit has to be lower.

Use the cold tire pressures on the fuel cap door and then reset as previously mentioned by pressing OK and accepting new values.
