...will not go off.? We are on a car trip in our 2005 Highlander and the tire pressure warning system light went on. Sure enough, we checked our pressures and one of the tires was flat, so we pumped it up. the other tired were ok. However, the warning light will not go off. The instruction manual doesn't give specifics as to the location of the shutoff switch for this light, other than that it is somewhere under the steering wheel. We are unable to find this light, and we are getting worried. The Toyota website also offers no help. Please, if there is a car expert out there that knows where this switch might be, please help us.
