• wherein the vehicle comprises a powertrain with a transmission system, wherein the transmission system is configured for automatic gear-shifting in an operational automatic mode and manual gear-shifting by a user of the vehicle in an operational manual mode, wherein the transmission system comprises a user input device configured for manually changing the operational mode of the transmission system between the automatic mode and the manual mode, wherein the transmission system comprises a transmission control unit for determining a recommended gear in the automatic mode and the manual mode, wherein the method comprises the steps:
• operating the transmission system in the manual mode, and in the manual mode detecting an operating gear of the transmission system by the transmission control unit;
• detecting a change of the operational mode of the transmission system from the manual mode to the automatic mode by means of the user input device, wherein if the detected operating gear in the manual mode when changing the operational mode to the automatic mode by means of the user input device is lower than the recommended gear the sailing functionality in the automatic mode is deactivated.
