Yup. When stopped, I turn up the thermostat from "LO" to some temperature and the ICE comes on. When I lower the thermostat back to "LO", the ICE turns off! Am I extracting any heat when the thermostat is set to "LO"? I assume not as that's just venting outside air. (Which is what I need in the summer to avoid the A/C) Sam.

Is there some combination of settings that will extract whatever heat there is from the engine without triggering the engine to start. Yes I realize by cooling the engine it uses fuel but that's got to be less fuel than outright running the engine when the vehicle's not moving and the battery is fully charged. Does anyone have more experience on the impact of cabin heat on fuel economy? I tried driving today without turning on the cabin heat (approx -15 C outside) and it appeared to only improve fuel economy from 7.2 L/100km to 7.0 L/100km. (When it was warmer I was getting 5.9 L/100km) Any other tips for conserving heat in the vehicle (short of grill blocks)? Thanks! Sam.
