What Does This Button Do On My '09?

At the bottom of the dash there is a little black button just to the right of the hood release that has the word "Set" on it with what looks like the profile of a tire. I have been through the manual and can't find it.

TPMS reset

 

Hi Rick I just found it in my manual it is the reset switch for the tire pressure warning. Page 373 in my manual.

 

Thanks, I must have missed that on in the book. So I guess if I get a low tire light I just have to air up the tire, push the set button and that will turn the light off.

 

its youre tire pressure monitoring system reset button you can adjust youre custom pressure due to towing or you can also reset youre tpsm ligh once its on and youve inflated youre tires. put it in park and hold it for a couple secs it will flash 3 slow times then youre good to go.

Thanks. I will dig the book back out and take a look.

 

Yeah and make sure if it does light up that it can also be your spare tire that is low on air. Happened to me once, put in a couple more pounds and hit the reset and it was go to go.

 

I may be wrong but I think the 09 trucks do not have a sensor on the spare tire that is why on the pictures of tire rotation the do not include the spare

 

Does it depend on which type of spare you have? I thought that there were at least two types of spares. I have the stock AT20 tires and I think mine is full size with the stock rim similar to the ones on the truck so I wouldn't be surprised that it has a sensor in the spare.

 

DON'T PUSH IT! It's the auto-release for your tires. If you push it and your truck isn't on jacks the wheels will fall off and you'll be sorry!

Or... what they said.

 

It's the button for the passenger ejection seat.
