You can precondition (heat or cool) the cabin for up to 20 minutes (10 minutes plus an additional 10 minutes if desired) but you need to initiate the preconditioning using either the key fob or the MyChevrolet App on your phone. You cannot program the Volt to start preconditioning at a certain time each day (if that is what you were asking.) You do not have to have the Volt plugged in to precondition but especially in winter it is desirable to precondition while plugged in. The Volt will draw power from the battery, this can cause your EV range to drop a few miles. If you are plugged in the on-board charger will recharge the battery so you won't start out with less than the expected EV range. In practice this works better if you charge using Level 2 (240V/16amp) as to use Level 1 would take so long to top off the battery that the cabin would be cold again by the time the charging was completed. With Level 2 you need an additional ~15 minutes to top off the battery however with the 2019 Volt and the 7.2kW onboard charger it may not require any additional time to top off the battery charge once the 10 or 20 minute preconditioning period ends.Sorry this is a newb question.
The salesman told me that I could setup the car to preheat the cabin based on my departure time.
Can someone explain how it works?
