Abstract

A method and a correspondingly designed motor vehicle are provided for pre-climatizing the motor vehicle when shut-off by way of a heating and/or cooling unit, which draws its energy for heating and/or cooling from an electric storage unit. When the heating and/or cooling unit is activated by a vehicle external operator control element, the heating and/or cooling unit is initially activated in a first output stage. Then, the heating and/or cooling unit is switched from the first output stage to a second output stage as a function of predetermined conditions.
