wrxhoon Posted November 29, 2013 Share Posted November 29, 2013 Does anyone know if the new (GSE31) sport luxury IS350 has it? If yes do you have to initiate it? Quote Link to comment Share on other sites More sharing options...
Lexus Nerd Posted November 29, 2013 Share Posted November 29, 2013 (edited) All third-generation IS models in Australia, including GSE31, are fitted with tyre pressure warning sensors. It is always active; it is not designed to be disabled.There is a button located below the steering column that will initiate calibration of the tyre pressure monitor over the space of two minutes. The Owners Manual does not suggest that you need to press the button following delivery of the car; however, I prefer to over-inflate my tyres by 4-6 psi, and so I calibrated the monitor after the first time I pumped my tyres.

wrxhoon Posted November 30, 2013 Author Share Posted November 30, 2013 Thanks for the heads up, I will look out for the button. Do you know how the TPS works? Does it detect the diff in rolling of the lower pressure tyre? I know tahts how it worked in my old Bimmer, it could detect as little as 4 psi difference. Has yours ever come up?

Lexus Nerd Posted December 1, 2013 Share Posted December 1, 2013 I'm not sure how it works. Unfortunately, the manual doesn't say exactly how much air pressure needs to be lost before the alert appears. I'm yet to see the alert myself, but I've only had to pump 1-2 psi each time I've checked my tyres. Quote Link to comment Share on other sites More sharing options...
