A method for performing a cold start in a vehicle having a power-spat transmission with a hydrostatic element comprising hydrostatic units. Several cold-start steps are performed sequentially for a cold start, the length of at least one of the cold-start steps is adapted depending on a temperature representing the start temperature of the power-split transmission. A state of the power-split transmission deviating from the temperature of the power-split transmission is monitored, during the execution of at least one of the cold-start steps, and, depending on this state, a transition from the respective cold-start steps to the subsequent cold-start step is performed, thus adapting the length of time of the respective cold-start steps.
