Increasing complexity brings with it the desire to combine the various display schemes necessary for the different automatic transmission variants in one display unit or one display module. To this end, provision is made to integrate the electronics for the display unit in the combined display scheme, wherein the electronics automatically detect which transmission is installed, preferably by a system cable harness of the motor vehicle, and hence which of the display schemes is needed in order to operate the appropriate light or display in accordance with the shift position. The unneeded display scheme or schemes remain in the deactivated state, and hence are not visible to the driver of the vehicle.

A coolant temperature control system for an internal-combustion engine in a motor vehicle having an electrically heatable thermostatic valve whose method of operation can be shifted by electrical heating in the radiator operation direction. Control devices are provided for recognizing a defect of another system in the motor vehicle which controls the coolant flow. When a defect of this other system is recognized, the thermostatic valve is heated. Particularly when a defect is recognized, the heating of the thermostatic valve is controlled such that the coolant temperature is maintained below a preset coolant temperature threshold. Preferably, the recognition of a defect is carried out by means logically monitoring output signals of the other system.
