A method and a device for operating a heat accumulator in a motor vehicle are provided. When the driver switches off the ignition, it is determined on the basis of the current coolant temperature whether there is a need for heat accumulation at this time and whether the benefit thereof depends on when the internal combustion engine is activated again. If the response to both of these is positive the driver is requested to state whether heat accumulation is to be carried out now. Heat accumulation is carried out or is not carried out depending on the driver's response.
