If a "GREAT SYSTEM" message is displayed on the Toyota display, it is necessary to stop and turn off the air-conditioner if it has been switched on. At the same time, the hybrid system itself is not needed until it is necessary to open the hood and check whether the hybrid cooling fans are working. If the fans are working, you must wait for the system to complete the overheating message and then turn off the hybrid installation. If the fans are not working, a hybrid installation must be immediately turned off and turned into the service. If you do not have enough antifreeze, you must add it to the highest level. If you do not have the antifreeze, you can fill in the water temporarily, but after that, you have to replace the entire antifreeze in the system.
