Hello, Currently my weather is -30. Normally to warm up a battery to help the engine, I can turn my ignition on to the start option and have the battery warm up to around 10-15 seconds then start my precious vehicle. i have a 2019 silverado keyless ignition. How can I do the same or is this longer an option as I haven't found any area to do the same with my key in my key fob. Any suggestions would be greatly appreciated. thank you
