A method for operating an exhaust gas treatment device having at least one heater and at least one supply device for a reducing agent includes initially carrying out a test in order to determine if the reducing agent is to be supplied, and subsequently implementing different heating strategies in each case. In the event that the reducing agent is to be supplied, the exhaust gas treatment device is heated with the heater until a first threshold temperature is reached, if a first temperature lies below the first threshold temperature. In the case when no reducing agent is to be fed, the exhaust gas treatment device is heated with the heater until a second threshold temperature is reached, if a second temperature lies below the second threshold temperature. A motor vehicle having the device is also provided.
