A method for operating a cooling system comprises at least the following steps carried out when a vehicle is started: - a first step (E1) which consists in checking whether the temperature of the liquid coolant in a low-temperature cooling circuit is lower than a working temperature of a high-voltage battery of an electric motor; - when the temperature of the liquid coolant in the low-temperature cooling circuit is lower than the working temperature of the battery, a second step (E2) which consists in starting a heat engine; a third step (E3) consisting in opening control means of a transfer circuit in order to cause liquid coolant to flow between a high-temperature cooling circuit and the low-temperature cooling circuit, thus causing the temperature of the liquid coolant in the low-temperature cooling circuit to rise faster in order to heat the battery until it reaches at least the working temperature.
