Thanks a lot, that does make a lot of sence, since the "Trac Off" light came on after I had accelerated at a traffic light. I registered my car at Lexus.com and ordered the manual. I did notice the "Trac Off" button on the drivers side around the knee area, and i tried pressing it to try and reverse the action but it failed to turn the light off. I did notice however that the light flashes once every time i turn the car on. Abnormal? Thanks again for the advice
