1. A method for operating a motor vehicle including a drive mechanism having a first drive unit and a second drive unit, comprising:
providing, in a first setting of the drive mechanism, by only the second drive unit, a first drive torque for driving the motor vehicle;
providing, in a second setting of the drive mechanism, by both the first drive unit and the second drive unit, a second drive torque for driving the motor vehicle;
upon exceeding a start-up threshold value by a demanded preset power, switching from the first setting to the second setting; and
upon falling below a shut-off threshold value by the demanded preset power, switching from the second setting to the first setting,
wherein the start-up threshold value and/or the shut-off threshold value is determined in dependence on a driving resistance of the motor vehicle and a vehicle weight of the motor vehicle,
wherein the driving resistance is determined with the aid of a state variable of at least one motor vehicle attachment, the state variable of the at least one motor vehicle attachment relating to the presence of the at least one motor vehicle attachment on the vehicle, and
wherein the driving resistance is increased when the at least one motor vehicle attachment is attached to the motor vehicle.
