If the toilet seat is cold, check if the temperature is set to "OFF" or a low level. When you sit, the heater warms the seat in about 15 minutes. If you've been seated for an extended period, stand up and then sit down again. Ensure you are sitting properly on the seat. Also, remove any toilet lid or seat covers.
