Turning off during Regen

Any harm?

No.

I think I just did twice in the past couple of days. I can here a fan running after I shutdown and detect lots of heat being blown from the engine compartment. I'd say perhaps it was just the electric drive radiator fan, but I was not driving long or hard, so no reason really for the radiator fan to continue running.

I'm just assuming it's the regen doing it's thing.

So what happens? It started about the time I got home - then put about 100 miles on it the next day, with no indication (via the hidden temp menu) of a regen.

I have no idea?

I don't worry about, just enjoy the ride!

Yeah don't worry about it. I have turned my car off countless times during a regen.

How does one know a regen is ocurring.

Sometimes you can smell a slight burning odor. Most of the time you don't even know, especially at freeway speeds.

The way that *I* was able to know was to watch the mpg reading in the instrument cluster.If it's,say,40mpg at a steady 65mph and then suddenly drops to 30 (still at a steady 65mph) then you know one's in progress.

I think it is the only way that your fans will remain running after you shut down the car. At least in my entire ownership it never has seemed my fans stayed on after shutting down and it was not within a regen process. The fans will run for quite awhile too.

As others have observed, there seems to be no real rhyme or reason to when the regens will occur;
I've seen one happen after a very short little hop of less than 10 miles on a cool morning, after an all
night sit. Another occurred after a long freeway run on a hot day. They just happen when they happen,
and I guess (hope) that the car knows what's best for itself. I've only actually smelled the "slight burning
odor" once -- when the car was quite new, and it was the first regen I noticed.

Mine seem to occur around every 500-700 miles with my style of driving. About once every fill up.
