We have an '08 RXh w/ nav. It has instantaneous MPG, the rolling 5-minute bar chart plus an MPG readout 'since last reset,' with a prominent 'RESET' button next to it (which we hit at refueling.)
To bump up from 26.9 and 7k miles to 30.3, I figure you'd have to coast for 885 miles. I'm guessing you somehow triggered the reset, maybe it's tied to a trip-odometer reset? Read the manual. Whatever you've been doing since the reset -- keep doing it. On one round-trip work commute, I got 35 MPG, so the highlander/RX's are capable of decent numbers, but you do have to work at it.
Break-in and warmer summer weather have made our last several tanks substantially better than the number in the sig.
