Hello everyone. Just bought myself a 2007 registered GS300SE (leather, sunroof, multimedia.) I consider myself pretty savvy when it comes to cars and electronic systems on board but even after reading the manual and playing with all of the toys there is just one thing that I need help on. The tyre pressure system dash light comes on and goes off with the ignition in a normal self test way suggesting the car has this on board BUT there is no button where the manual says it should be to initialise it. So does that mean the light is bogus and it is not fitted or is the manual wrong?
