Check engine light?

[CamJam1]

Just finished a 3,200 mile trip and the W-22 performed nearly flawlessly. The only hiccup I had was one morning when the temperature had dipped into the low 30s. On startup I had a light illuminate on the dash that looked like an asterisk with an exclamation point in it. Wasn't sure whether this was a check engine light or some other warning. I know my car sometimes gives a warning when the temperature reaches near freezing to warn of the possibility of icy roads, but by the time we hit the road that morning the temperature had climbed back up into the 40s. In any case, the light went out after a few miles and I haven't seen it since. Just wondering if anyone can tell me what that might have been about.

Took a quick look at my owners manual. There are two that have asterisks as part of the symbol. One is for the transmission, the other for the brakes. There is a third for TPMS if your coach has that built in.
