Engine Running Full Charge

It was really hot when I started my Volt about 10:30 this morning. It's about a mile to the pavement and I have to drive slowly so not much cooling and I had the air on high.
So I get to the pavement and stop at the mail box and I can hear the engine running. I open the hood and look at it, it's running.

The panel doesn't show it's running but it's running.

I went ahead and went to the store and it ran there when I started it but I heard it stop running after I was driving around.

So it must come on for extra cooling or something?

From my 2014 manual:
Electric Mode
In Electric Mode, the vehicle does
not use fuel or produce tailpipe
emissions. During this primary
mode, the vehicle is powered by
electrical energy stored in the high
voltage battery. The vehicle can
operate in this mode until the
battery has reached a low charge.
There are some conditions when the
battery charge is high enough to
provide Electric Mode operation, but
the engine still runs. They are:
. Cold ambient temperatures.

. "Hot or cold high voltage battery

. The hood being open or not
completely closed and latched.
. Certain high voltage battery fault
. Engine Maintenance Mode or
Fuel Maintenance Mode
being run.

So apparently the high temp will trigger it :)
