The issue of people with aftermarket radios not being able to follow the usual instructions.
Here's a link to a thread that addresses this issue and gives a solution.

Hope this works for you.

 

what about the people who have the last model of the montes the 07 7th gen cars if ichange my head unit i am screwed right?? because my oil life and low pressure ights and gadges are controlled by the four bottons by the dash i never had to press the gass peddle to reset my oil lif indicator just hit a booton it is resett the onle thing that i had to do with the tire pressure to low is to replace all the sensors /or take the sensors off and the tire montering system off because i am haveing a problem with it got new tires and sensors now every time i start my car it said all my tires are flat even though the tire montering system has benn reset

 

you should probably check with the shop that installed your new tires. They should be able to replace a few parts for a little extra $. Everything should work like new after the repairs have been made. They should have done this/told you about it when they were installing your new tires.

 

Would this work for a 2000 monte carlo ss supercharged???

 

Thank you very much montejass!!!!

 

it will work to bro

 

k i know this is a old thread, but i went threw my radio functions like stated above, and i couldn't find anywhere threw the settings for the tire mon. why is that? i seen everything else like (reset oil life,alarm,fob horn,trunk lock) but not the tire one?

 

Justin - There is a faster way to do it without the radio.

Start your car.

Pull the headlight *** back one click and push it back in. Repeat the pull/push 2 more times within 5 seconds and the dash will beep and the tire light will go out.

 

I turn the ignition to the acc position, then on and off the park lights 3 times..that resets it on my 02
