Up here in Canada, I had to install winter tires on my IS 250 RWD. I did not install tire pressure sensors and now I have 3 bloody warning lights on my dash that wont go away. Anyone know how to bypass this function? Help is greatly appreciated!!!

 

If you search you will find multiple threads solving this problem.

 

you could do the tpms bomb which in stickied in the DIY thread... or take it to lexus and they could actually turn off your tpms for you...

 

Welcome to Club Lexus! Take a moment to browse through our FAQ thread, stickied at the top of the 2nd generation IS forum. In there you'll find several different solutions to this problem. Since you're in Canada and will have to run winter tires a good part of the year, I'd look into investing into a second set of tire pressure sensors. Your car will accept two sets of sensors to be programmed into the memory, and you can toggle back and forth between them depending on which set of wheels you're running.TPMS cannot be turned off or disabled, even by a dealership.
