hey guys quick question. I just notice this, under where the fuse box on the driver side is next to the OBD port what is that button that says "SET" ? and next to it i have a empty slot am i missing something there?
car is a 2014 is350 f sport.

 

Do you have TPMS? i think its for setting the low tire PSI range.

 

Yep i have TPMS. i see so pretty much is this how it works? put the amount of psi in the tires then click the set button once it falls below that it would alert you on the dash?
and as for the other slot next to it am i missing something? or its suppose to be blank?

 

upload a picture so i can see.

TPMS, hold the button and when it goes under a certain value ( i think its like 10 psi? under what you pushed the button at) there will be a warning.

 

Here is the picture i took

 

not sure what that empty spot is, i have it as well.

 

oh, at least its not only me LOL, let see if someone else can confirm that slot. But thank for the reply.

 

Why don’t other cars have this? 2015 is250 f sport

 

are you saying you dont have the "set" button ? Do you have tpms?

 

My bad I just saw it. I’ve been under there a few times and nerve noticed it. Just pressed it a few times nothing happened while driving

 

Oh, my, what's next to the button? . The TPMS sign...., LOL! Haven't read or looked up the owner's manual?

 

Isn't the TMPS sign like this (!) most car i seen have that. lol why look up when you can just ask.

 

I have no idea what the blank spot is for, but the TPMS "Set" button is used for when rotating the tires according to the owner's manual.

 

Found out what the blank spot is...
Adaptive Front Lighting system.

 

You all found the ejection seat button! Don’t press it. Or read Hefferners post.
