Claim:
1. A method for operating a motorized actuating device for a selectively liftable and lowerable vehicle part, the method which comprises: moving the selectively liftable and lowerable vehicle part towards a target position by energizing an actuating motor of the actuating device; stopping the actuating motor of the actuating device at a predetermined lead before reaching the target position of the vehicle part; varying the lead in dependence on a rotary speed of the motor or an actuation rate measurement variable correlated with the rotary speed of the motor and in dependence on a temperature measurement variable characteristic of an ambient temperature of the actuating device; upon lowering the vehicle part, increasing the lead relative to a corresponding lead value when lifting by a correction term that is dependent on the temperature measurement variable.
