A vehicular rearview assembly with a heating element. The heating element is affixed behind and in thermal communication with the mirror element of the assembly. The heating element includes a plurality of heating zones that operate in alternation according to a pre-determined time-sequence. A peripheral area of the mirror element is heated up to at least as high a temperature as an inner area of the mirror element. Switching the heating zones on and off so as to have only one heating zone on at a time is determined by a controlling circuitry at least a portion of which may be separated from the assembly and disposed in a different part of the vehicle.
