If you live in a semi-colder climate, you are likely well aware that winter is here. Thanksgiving has come and gone, and Christmas is now just around the corner. And for those who don’t live in the far south, that means colder temperatures and possibly snow and ice have already brought goosebumps to your skin at least once this year.

It also means that you’ve likely had to make a few changes to your driving routine. You know, things like starting your car early to let it warm up, brushing off snow and ice, and taking the roads a little slower and more carefully than you might do in the summer months.

But for EV drivers, at least those driving Ford’s F-150 Lightning electric pickup truck, there are a few more things you should take note of. And not necessarily welcome ones.

Tip number four on the manufacturer’s guidelines for using your Lightning during the winter, for example, says, “If equipped, use the heated seats and steering wheel as primary heat to reduce energy consumed by HVAC.”

Now, this is somewhat practical. After all, if it’s only 50 or so degrees out, you might be able to get away with just turning on your heated seats to remain comfortable. Hell, I do that in my gas-guzzling car.

But at the same time, it’s a bit off-putting. Essentially, it means that turning on the actual heat will drain the battery, making you have to stop and charge your vehicle a lot more often. So don’t if you don’t have to unless you are prepared to stop and charge quite a bit sooner than usual.

Similarly, the next tip tells you, “when charging, turn off the heater if possible.” So, if you have to stop somewhere anywhere other than home, be prepared to get cold as your Lightning charges, as this, too, drains the battery. Maybe you should pack some extra blankets, hand warmers, etc.

Hell, we could always go back to how they used to do it and heat up rocks, wrap them in blankets and place them at our feet… Because that sounds practical.
