    There are two separate coolant systems, one for the gas engine (larger tank on the left side) and one for the electric drive (smaller tank on the right side). Hybrid system error and subsequent shutdown of the drive system could occur if the inverter coolant system is not working and the car is protecting the electric drive. Also, in addition to the warning screens, you need to pull the codes to be sure.
