Set button

Hi was cleaning my car out when I noticed this button. What’s it for and how do I use it?

 

It's the set the bomb

 

Technically to reset the tire pressure monitor system TPMS

 

Haha thanks. So I’d use it for example if I air down then air back up later?

 

I guess you could, I’m not sure how low it will let you reset the parameter. Doesn’t hurt to try. I think you hold it down with the key off and then turn the key on while holding it down, when you have the tire pressures set where you want them. I want to say if it drops 5 pounds the light will come on to let you know you have a low tire. Should be in the manual for exact directions. When I air down I just live with the light LOL.

 

Once you turn your truck on you have to push that SET button so the MPGs are 20+. Most people ignore it then complain about sucky mpgs on their Tundras.

 

From the manual:

 

Gotcha was thinking it was like a change oil light but this is for resetting to why you want the pressures to be at. Thanks!

So if the button doesn't make the light flash (because it's already on) probably check the actual TPMS sensors next?
