I'm wondering if anyone else has experienced this. I had my C6 out this afternoon the temperature was 6 degrees above zero. It probably sat for about an hour at that temperature, when I statred it and began to drive the Low Tire Pressure indicator was lit, and in the DIC it displayed one after another that every tire was low. After about 5 miles of driving it went away and was back to normal. I'm wondering if this is normal.

Sounds like a cold deal.

Keep in mind that air contracts in the cold so that could be what is happening.

Obviously you are near the set point for the system to say your tires are low and the cold outside air dropped the pressure just below that trigger point. Read the tire pressures using your DIC without driving and adjust them to the spec.

Thanks for the info, I will try that.....
