Can you or anyone tell me what the "30 mph" after reset means? I understand what range means but 30 miles per hour, I just don't get. Mine has it too. 2022 RX 450h

 

it means that since you last reset your average speed and fuel consumption by holding the dot button, you have been averaging a speed of 30 MPH.

 

When at a traffic light, your speed is zero. mpg at Zero mph is terrible in a 350, with a hybrid it is dramatically improved.

Unless you put in a lot of 8-hour days at 60 mph without traffic, it is hard to get that above 30.
