Cold weather expectations...

We had our first significantly cold day of the season (highs in the upper 30s). Left work late and the DIC was all lit up with Low Tire Pressure warnings for all four corners. They have been 29/30 psi since I bought the car last July, then BAM! all four were 25 psi after one cold day. Topped them off to 30 psi and have been keeping an eye on them.

Is 5 psi drop for cold weather normal?

Also noticed that my gas gauge doesn't like cold weather either, it squawked Low Fuel on startup, then eventually drifted back up to where it should be.

Are there any other C5 cold weather quirks I need to be aware of?

Thanks

I think I've jacked my up about 5 lbs since it started cooling off. Added 2 or 3 lbs two different times. Bet you're fine.

Low tire warning came on for me. It was 30 degrees last nite. Normal on them is about 30 PSI so I guess the 5 # drop is about normal.

yes it is normal, and by the way, the tires on your other vehicles do it to so now is a good time to check them.

This actually sounds more like a gas gauge issue then cold weather problem - possibly caused by a 'sticky' fuel level sensor. Many have had similar problems that have been resolved by using a bottle of good fuel system cleaner, or a reprogramming of the car's computer to make it less sensitive to sulfur content in gas, or had the sending units replaced.

I heard 1psi per 10-degree drop in temp. Sound about right?

Had the same thing happen here this week when temps dropped into the 20's. Saw several postings to put 30psi in cold. Did that yesterday morning with no alerts since. Hope this helps.
