Yes, but the fuel economy will be reduced somewhat.

Which is why I usually do not use the heater much at all unless I must.

I have to say I "just drive it" and let the car manage itself. If I'm cold
I'll use the heat and if I'm hot I'll use the cooler. Don't see a lot of
point in switching off the heater when the car is being driven - all it
means is the heat generated by the engine will go outside the car rather
than inside! Only if the car is standing for long periods will the engine
be needed solely for cabin heat. In my case (UK) the difference in gas
mileage between winter and summer is about 5 mp(UK)g I'm prepared to
tolerate this for a bit of comfort!
Cheers

Hi Chas,
My wife just drives it and that is all fine. I find myself being tuned in
to the little things. It is all good. Between us I find that I will get a
couple of MPG higher (by this I mean that I generally push the tank's MPG
average up a bit and she generally brings it down a bit to over-generalize).
I do find that the engine does indeed start up when I would expect it to be
of, solely due to the call for cabin heat. There will be times when I do
the foot trick to get it to stealth on a flat road and it just will not turn
the engine off. Turning off the heat at that moment fixes that problem I
have found.
Over the last 4 thankfulls we (together) have been getting 53 MPG average
here in NJ.

The car's battery was probably low, which can happen as a result of
inefficient driving.
