this error msg keeps coming on in this stupidly cold weather. on a base model '07 H3 it's telling me to top up the tire pressure yes? base model H3's dont have a compressor ....correcT?

Unless you added it.... correct no onboard air compressor on your H3.

You tires likely just need a top up from the cold air. This warning should disappear when your tires warm up driving but if it’s coming on at all you likely need more air. I never had this issue with our H3 running 33” BFG TAs

Possibly your TPS sensors are running out of battery and need replacement.

Either way not a big issue.

Good luck and let us know how it works out.

This message pops up for me too for a second when it’s really cold.

Might need to replace your tire pressure sensors, mine are long over due.

topped up the air msg went away. amazing how much pressure tires lose in the cold

I had such message couple times on my H3 during the coldest winter mornings. After short drive it will be disappeared.
