I see a temp gauge for the temperature outdoors, but not for the interior. I see a goal temperature in the HVAC settings, but not a statement of what the temp is in my cabin.
In order to maximize range last night I drove in 32 weather but without the heater operating in the cabin. I am sort of wondering what the temp was. Also wondering if any fresh air is being brought in and whether I need to crack a window.
Ultimately, maybe more houses and cars should also have CO2 gauges to give a better idea of fresh air (might help with alertness while driving). I bought a CO2 gauge for my house when I was alerted by an energy audit that the house is very tight, and this has helped me to have a better handle on when/where/how-much to ventilate.
