Reset Tire Pressure Warning on 2009 Toyota Highlander Hybrid

The Tire Pressure Warning is sitting on my center console screen, the warning lights are on. I checked my tire pressure and they are ok. I want to turn off the warning but it wants me to go to the dealer. We have a 1,000 mile trip to look at this. Any suggestions on how to reset it? The normal hylander tire pressure reset button that is below the one off switch at the end of the molding is empty. (you have to get on your back on the floor to see there is no longer a reset switch in that location). Any help would be appreciated!

If the tire pressures are OK, check the spare wheel tire pressure. Lexus and Toyota monitor the spare wheel if is a full size spare. If the spare wheel tir pressure is OK. let 10 psi out of each tire and refill it to the correct tire pressure. Drive the car a few miles if the tire pressure monitor light is still on a scan tool needs to be connected to the 16 pin diagnostic socket under the dash. The scan tool checks the battery voltage at each sensor, the tire pressure and tire temperature at each wheel and sees that communication between each wheel and the computer is OK.

Yes! Thanks for the suggestion, this worked for me. Other sites suggested I look for nonexistent tire-pressure reset switches on my 2009 Highlander, when it was just the spare needed some inflation.
