Agreed. Just had this happen yesterday. Started car, EMM message pops up. I knew the first leg of my drive would be less than 10 minutes, so I hit the "delay" button. Finished first errand, got back in and restarted, then let the car do its thing during the 20 minute drive to the next destination.The car is smarter than any of us. Let it do it's thing. That is unless you are making a really short trip and expect to do a longer one later, in which case I've selected to delay EMM. Once I used hold and there was no benefit. I think EMM uses specific RPMs and times to achieve a specific objective and there's no point in trying to out think it.
EMM usually uses less than a cup of gasoline, and I'm not sure that the gas-o-meter even pays attention to less than a tenth of a gallon.Agreed. Just had this happen yesterday.

Didn't seem to add anything to the battery (though I had the A/C blasting and was going 70 mph most of the way, so couldn't really tell), and my gas miles remained unchanged (which would NOT be the case in Hold mode).
Do you have low gas or an active MIL? Remote start will not go in either condition.Whenever I have a pending EMM, remote start fails.
It's higher than ERDTT and has to hold it there for longer. ERDTT peaks and drops instantly as heat is being sucked out of the system.I believe it has to get the engine to optimal temperature (same temp it climbs to for winter ERDTT) based on watching the engine temp for each. I seem to recall hearing this elsewhere to, but will leave ya to do the Googling to confirm or deny
The net result of a gen1 EMM is electricity used.When the EMM message pops up, it usually is the first thing in the morning when the battery is fully charged. I always say "no," and drive several miles to get the battery SOC down a bit. I found if the battery is already full EMM cannot run the engine very hard, so it does not warm up fast, extending the time required for EMM a great deal. Since I am just driving on slow streets the car doesn't use much power, but if the battery is not full the Volt will charge it up to load the engine properly.
On the next start-up of the day I will say "yes" to EMM, but only if I plan to drive further than about 5 miles. That way EMM will be completed before I reach my destination. Otherwise EMM will resume on the next engine start.
I drive a 2014, gen 1 Volt.
(And when you ask yourself why not generate? Because unloaded engines use a hell of a lot less fuel, and EMM's goal is just to get some number of revolutions done as efficiently as possible and make sure oil and coolant go where they're supposed to go when they need to go there.)The net result of a gen1 EMM is electricity used.
It does not generate electricity for the duration of the test. It will end up using more than it generates, which only happens for the first minute or so @ ~6kW (not even enough to fill the over-regen buffer).
I guess it depends on what your goal is. If your trying to get the most EV miles. Delay it. Then when parked somewhere. Let it run while the car is parked, and you wont get an miles under gas. If your just wondering on energy saving, hopefully within that 24 hr window, you have some highway driving. Delay it then when you get on the highway, go into hold mode.I haven't had it happen yet, but what do you do when EMM pops up? Is it best to switch to hold mode and just drive normally? Basically, what would be the most efficient thing to do when it pops up?
