Happened to me as well. Got a warning when when the car was started from cold which disappeared when the car warmed, even on a restart. The difference in total coolant required to bring the level from just below minimum on the guage, which will trip the low coolant sensor, to maximum is pretty small. Apparently it's quite common to get a low coolant warning when the weather turns cold if the level wasn't close to maximum.
