I had new tires installed with new TPMS sensors installed. How do I relearn the senors for my GX470?

Where you bought the tires from should be able to sync your new TPMS sensors to your GX470. Current sensors will last about 5 years because of the batteries in them. You will get the warning light even if tire pressure is good when the battery in them expires.

Thank you for the feedback. Unfortunately, I live in an area where there is no Lexus dealership and the Toyota dealership in the area has a poor reputation. I did buy the tires from Tire Rack online and had them mounted at a Honda dealership. Honda did have the technology to complete the learning process. Dave

Hi Dave, Glad you got your sensors working at the Honda dealer. My suggestion was that most places (need not be the particular car dealer associated with your car) that install tires usually can get the sensors to work correctly which the Honda dealer did as you mention. We have use Costco and they have done two tire sets on our cars (Nissan & Lexus) with sensors we provided and they work perfectly. They did charge a little extra for doing this but worked out less cost than using the TPMS brand they had.
