i have an 08 chevy impala and the computer is showing that my tire pressure is low but im sure that it isnt. i would appreciate if anyone can tell me what buttons to press in the information center in the dash so that the system will relearn the information and update. thank you very much for your time in reading this post an possibly responding

 

I looked through the owners manual for the 2008 Chevrolet Impala and found that in section 5 page 67 you can find the Tire Presure Monitoring System learning process. It goes through all the steps you need to go through for your system to relearn tire positions and pressures. I hope this helps you.
