The invention relates to a method for operating a cooling system (10) for a hybrid electric vehicle comprising at least one heat engine (12) and an electric motor (14), the method for operating the cooling system (10) in the electric mode comprising at least the following steps: - a step E1 consisting in determining whether the temperature of the liquid coolant in a high-temperature cooling circuit (100) is lower or higher than a threshold working temperature (TFmax) of a low-temperature cooling circuit (200); and - when the temperature of the liquid coolant in the high-temperature cooling circuit (100) is lower than the threshold working temperature (TFmax) of the low-temperature cooling circuit (200), a step E2 which consists in opening control means (302, 306) for controlling a transfer circuit (300) which interconnects the high-temperature cooling circuit (100) and the low-temperature cooling circuit (200).
