So this morning it was 6 below zero F. I remotely started my 2016 TH (70,000 miles, automatic transmission) to let it warm up for about 5 minutes before I got into it. I noticed an amber warning light lit just above the P. It looks similar to the transmission over temperature warning light. It was a gear symbol with a small flat rectangle box at the top and an exclamation mark in the center. (It didn't have the combination thermometer/exclamation mark like the transmission over temperature warning light) Is this a "service transmission" symbol? There was no other message displayed with this. I cannot find it in the owners manual. It disappeared after 15 minutes of driving and it drove normal with no issues. Just wondering what the symbol may mean and why Jeep doesn't show this in a manual. It's a gear symbol. Shouldn't that be important enough to make the list in the manual.
