Cat mt855

Just about to take delivery of a cat 855. It's being trucked as I write. After leaving it running on the truck in temperatures of -20 and below two warning lights have come on. Both lights are for track tension,left and right . Is this a result of the cold and idling with thicker oil or is a sign of more serious problems. When I looked at the tractor and drove it before buying it all worked good.

Thanks
