I drive a 2007 Volvo S80. I just had the battery replaced last weekend, and as I was driving home from the battery shop the tire pressure warning light came on. My tire pressure is okay and was at 38psi in all 4 tires. The pressure is not low. Since then, every time I start the car, that light blinks for a minute, then goes off, but about 10 minutes later I get the warning again which stays on while driving. The other thing I noticed is now the power windows require me to hold the button to operate them rather than just press and release. The “auto down or up function stopped working once the battery was replaced. Did replacing the battery cause my computer system to malfunction, and does it need to be rebooted to clear everything and normalize the car? How do I do this?

what about the tire pressure reset issue? what about the tire pressure reset issue?

Don't know about the tire pressure, I had the same thing a few months ago but all tires were fine. Someone said it might be the spare, but we just turned off the light. I DO know how to fix the auto up/down issue..its in the owners manual. Just did it today. With the window up, hold the window button up 1 second (you will hear a click), let go a second, then up a second again (you will hear another click). The auto feature should work now!
