Park overnight. Once fully cold, remove crossover cap and check if crossover is full of coolant. Top off as necessary and replace cap. Then you can top off reservoir as needed. *Do not open reservoir with crossover cap removed.*While on the freeway the low coolant message came on... for about 2 minutes.. then turned off (!?!)
Pulled over.. checked the reservoir and it is 2 inches low... no leaks at all anywhere I can see.
Parked in the garage now. No leaks still. Is this a common thing to have happen as the system gets running after a change?
