You can check the interior temperature and heat or cool the cabin before driving (even if it's in a garage), control the seat heaters, and defrost the windshield:
Using the mobile app to precondition Model S also warms the Battery as needed. The mobile app will notify you once your vehicle has reached the desired preconditioning temperature.
NOTE: In extremely cold weather or icy conditions, it is possible that your charge port latch may freeze in place. In cases where you cannot remove or insert the charge cable, or the vehicle is not Supercharging due to the latch being frozen in place, use your Tesla mobile app to enable Defrost Car for approximately 30-45 minutes. This can help thaw ice on the charge port latch so the charge cable can be removed or inserted.
