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.

1. A method for pre-climatizing a stopped motor vehicle using a heating and/or cooling unit, which draws energy for heating and/or cooling from an electric storage unit, the method comprising the acts of: operating the heating and/or cooling unit in at least two output stages, wherein (i) when the h
1. A method for pre-climatizing a stopped motor vehicle using a heating and/or cooling unit, which draws energy for heating and/or cooling from an electric storage unit, the method comprising the acts of: operating the heating and/or cooling unit in at least two output stages, wherein (i) when the heating and/or cooling unit is activated by a vehicle external operator control element in a stopped state of the motor vehicle, using a first output stage, wherein when each of a charge state of the electric storage unit is above a predetermined level and when an outside temperature is much less than an interior temperature of the vehicle, the first stage comprises performing both, in a first step, a flushing process of the interior of the vehicle and, in a second step, operating the heating and/or cooling unit at a first capacity; and(ii) switching the heating and/or cooling unit from the first output stage into a second output stage as a function of predetermined conditions, where the second output stage comprises operating the heating and/or cooling unit at a second capacity which is higher than the first capacity. 2. The method according to claim 1, wherein the first output stage comprises: (a) only performing the flushing process of an interior of the vehicle when the charge state of the electric storage unit is below the predetermined level; and(b) wherein when the charge state of the electric storage unit is above the predetermined level but the outside temperature is not much less than the interior temperature of the vehicle by at least the predetermined amount, the first stage comprises only running the heating and/or cooling unit at the first capacity. 3. The method according to claim 1, wherein the first capacity is at or below the average capacity, and the second capacity is a high capacity. 4. The method according to claim 1, wherein the switching from the first output stage to the second output stage occurs when a vehicle door is unlocked or opened. 5. The method according to claim 4, further comprising the act of not activating or deactivating the heating and/or cooling unit when a charge state of the electric storage unit falls below a predetermined minimum value. 6. The method according to claim 4, wherein the vehicle door is a driver door. 7. The method according to claim 1, further comprising the act of not activating or deactivating the heating and/or cooling unit when a charge state of the electric storage unit falls below a predetermined minimum value. 8. The method of claim 1 further comprising: determining, periodically, if a vehicle door is unlocked or opened; anddetermining, in the event the vehicle door is determined to not be unlocked or opened, if a charge level of the electric storage unit is below a predetermined minimum level; anddeactivating the heating and/or cooling unit if it is determined that the charge state of the electric storage unit is below the predetermined minimum value. 9. A motor vehicle, comprising: a heating and/or cooling unit for pre-climatizing the motor vehicle when stopped, the heating and/or cooling unit drawing energy from an electric storage unit of the motor vehicle;a vehicle external operator control element for activating the heating and/or cooling unit; andwherein the heating and/or cooling unit is operable in at least two output stages, the heating and/or cooling unit being activated in the stopped state in a first output stage and being switchable from the first output stage into a second output stage as a function of predetermined conditions,wherein, when each of a charge state of the electric storage unit is above a predetermined level and when an outside temperature is much less than an interior temperature of the vehicle, the first stage comprises performing both, in a first step, a flushing process of the interior of the vehicle and, in a second step, operating the heating and/or cooling unit at a first capacity, andwherein the second output stage comprises operating the heating and/or cooling unit at a second capacity which is higher than the first capacity. 10. The motor vehicle according to claim 9, wherein the first output stage comprises: (a) only performing the flushing process of an interior of the vehicle when the charge state of the electric storage unit is below the predetermined level;(b) wherein when the charge state of the electric storage unit is above the predetermined level but the outside temperature is not much less than the interior temperature of the vehicle by at least the predetermined amount, the first stage comprises only running the heating and/or cooling unit at or below an average capacity. 11. The motor vehicle according to claim 9, wherein the first capacity is at or below the average capacity, and the second capacity is a high capacity. 12. The motor vehicle according to claim 9, wherein the switching from the first output stage to the second output stage occurs when a vehicle door is unlocked or opened. 13. The motor vehicle according to claim 12, wherein the vehicle door is a driver door. 14. The motor vehicle of claim 9 wherein the heating and/or cooling unit is deactivated if it is determined, in accordance with periodic checking, that a vehicle door has not been unlocked or opened and that a charge state of the electric storage unit is below a predetermined minimum value.
