connected to L2 charger I turn on precondition.
if you perform a remote start, I wouldn't think the car would turn the steering wheel heater on. Oh wait, my 2017 isn't automatic so may behave differently. But mine will automatically warm the car (in winter if the car's interior is cold) during a remote start regardless of my heat settings. Once I "start" the car (push the start button in the car), it will go back to my settings at last shutdown which might have the heater off.

I RTFM and it says it will retain previously setting on HVAC. The problem here in the shoulders of winter in Maryland is that I could be leaving the car with outside 50, (HVAC off) and getting in the morning with temps in the 20鈥檚

My 2017 manual has the following which is a little ambiguous:
Use remote start to heat or cool the interior when the vehicle is plugged in to maximize electric range by utilizing electricity from the electrical outlet. Normal operation of the system will return after the vehicle has been turned on.
I bolded the part about it returning to normal operation. I've seen my Bolt on multiple occasions heat the interior even though I had the heat turned off. Likewise for cooling. Also interesting that the manual never mentions preconditioning. This term comes from the app that I've never used. Since there's no settings in the app, I've assumed that it works the same as the remote start that is described in the manual. Would be tragic that the app would behave differently if that's the case.

Nevertheless, that's how it works, so get used to it.

2019s do heat the steering wheel, but it is thermostatically controlled, so unless it is under 50F or so, you may not notice, and as it heats, it turns down the number of dots on the seat heater button, so you might not notice.

I have that issue in Michigan as well, but this is how all my ICE vehicles have always worked too, just a matter of estimating what the morning will be and adjusting the heat settings before turning the car off, it will then use those settings the next morning.

Newbie (picking up new 2021 Bolt later today if all goes week) chiming in FWIW:

I like the way this precool or preheat works on our MiEV.
About 10 to 15 minutes before I intend to druve I use the remote control fob (same one that sets charging time) to tell it to preheat or precool. If I space out and forget it stops preconditioning after 30 minutes.

Sound like from this discussion can,t quite do that on the Bolt.

There are 2 ways to precondition the car:

1. With the keyfob, press the lock button, then hold down the start button.

2. With the MyChevrolet app, hold down the start button

Preconditioning will use the most recent HVAC settings. I just press the Auto button before I shut off the car.

If your Bolt has heated seats and the heated steering wheel, there is a setting in the Infotainment system to allow them to be managed automatically. Leave that setting on if you want them to be included in the preconditioning process.

Preconditioning lasts up to 20 min, and can be done twice before starting the car.

I don't believe that is entirely accurate. I rarely use HVAC, relying on fan only with Heat\AC 'OFF'. Yet, whenever I precondition, it warms the seats and cabin automatically if it is cold out, or cools when it is hot. So, while it may use previous settings, it also seems to sense ambient air temps and condition to a comfortable level.

I can understand the seats being heated automatically based on the vehicle settings. For the actual cabin heater / AC, however, do I understand that you turn both heat / AC off, shut off the car, then see one of them (heat / AC) turn itself on when you precondition later?

I'll have to try it some more, but my memory is that if I turned everything off and just used the fan before I shut off the car, preconditioning would just use the fan. That's why I usually hit the "Auto" button before I shut off the car.

I don't see anything, it preconditions, warming or cooling the cabin when I left the car with heat\AC off. When I get in the car. range shows on the GOM, when I start the car, heat\AC remain off and the GOM jumps up about 20 miles of estimated range. Been so for 3+ years.

will this work with a 2018?
