What is this..?

I have a 2.5 inch lift and this thing popped up.. sorry if this is a dumb question but I don’t know what it is.
Idk if the lift has anything to do with this.

 

If you're talking about the yellow light, its your Tire Pressure Monitoring System (TPMS). Just means your tire pressure is low.

 

Tire pressure. Scroll through your screen to see if one of them is low

 

I checked that and all I see is lines, it doesn’t tell me how much psi I have.

I guess it’s mybad for not describing my issue more

 

You should have a button under the steering wheel to reset/recalibrate the TPMS. If light turns on, it doesn't necessarily mean you're low pressure-- it means you're outside of the range it was initially set at.

Did you install new tires with the lift? It also comes on when you have a slow leak.

 

You have to drive around the block at least for the thing that read pressures. Give it a drive then check the screen, or just pump them up to whatever is recommended.

 

Example: tires were at 38psi when last reset. Now you air down to 30psi and the light will turn on.

 

I did get new tires and I got 285/75r16 if that matters.

 

I got them installed on Wednesday, I’ve been driving it ever since. I kinda figured it would’ve read by now. Sorry I’m just new to all of this.

 

Oh if it is a new install then the TPMS needs to be reset for the new tires. Take it back to the shop and have them reset it or have Toyota do it, either way it should be free.

 

Sounds good. Thank you for the help. I was getting worried I screwed up.

 

No worries. I was just having fun...the posts before mine answered your question

 

All good man haha

 

Check your tire pressure, start engine then press the reset button located under the steering wheel until the indicator light blinks 3 times.

Hope this does it for you

 

Push and hold the button under the steering column and it should reset to your current pressure. That's how it works on a 2nd gen. Maybe with 3rd gen you do it on the instrument panel "computer".

Edit: thanks old man. Apparently it's now in the glove box. You shouldn't need to go to the dealer for this.

 

If it was working fine and the light just came on, then your pressure is low. Check them manually and air up where you’re low.

The lines on the TMPS are because it needs to be driven for a few hundred feet before it can register the pressure.

 

Or if you got new wheels too... there may not be any sensors in them.

 

That was what I was thinking too.
