Break-in period.  Again.

Yesterday, I got to test-drive my car.  It was sweet.  (I have
a lot of reading to do, though.  <g>)  I mentioned something
about the break-in time, and the salesman said there was NO
break-in time.  I am going to have to check this out very
carefully.  I obviously have to err on the side of caution....
 Mebbe I will go ask at the two major Prius forums today too....

Anyway, I could have picked the car up tonight, but since that
required the salesman to stay after his normal hours, I
decided to be kind and get it tomorrow morning....

"How do you know when a salesman is lying?  His lips are moving."

Or maybe he really didn't know, or maybe he was comparing it to the
"always vary your speed" break-in recommendation for old technology
cars.  Anyway, Prius does have a simple break-in procedure, given in the
owner's manual.  Paraphrasing: no "excessive speed" (? more than 60
MPH?) in the first 600 miles, and avoid hard braking in the first 200
miles.

Well, I will study the manual--and be cautious....  This
dealership/salesman is odd....

Actually, the car was already braked fairly hard, because a
car pulled out right in front of us during the test ride.  The
salesman was not amused at that near miss and thought the car
was unavoidable.  Obviously, one does have to brake hard under
such circumstances, but one can usually avoid it.

When I got mine, the dealer said the ad naseum 60-40mph routine and repeat.
However, in the real world once I got on the Interstate I had a long stretch
to go on I-5 and it moved along at 80mph without a hitch and some of it up
over the Grapevine's uphill 5 mile stretch.

So much for babying it..

Well, I did look at the manual, and it cautions re
accelerating, braking, and something else (which I guess
either must have been obvious to me or ???).  Anyhoo, I got it
home with nothing untoward happening.

I wonder how long it will take the battery to be fully charged?

Also, I gather when there is no green or orange on the energy
consumption screen, that is the famous stealth mode?

Hi Jean,

The Prius battery array (not the small battery in back) is primarily for
energy storage.  You will rarely see it fully charged and hopefully never
see it discharged.  In a conventional car the battery has only two purposes,
starting and as a voltage regulator, and is returned to a full charge
quickly once the car has been started.  The Prius battery is an energy
reservoir.  It would be counter productive to maintain it at a full charge
because then you would not have a place to store energy recovered going down
hill, coasting or braking.

"Stealth mode" is achieved when the engine shuts down and you are running on
energy stored in the battery.  Generally speaking you will be in stealth
mode when no arrow is coming from the engine and an arrow is going from the
battery to the front wheels.   With experience you will learn to manage your
acceleration in order to maximize the stealth experience and achieve better
gas mileage.  For example, if you see a light turning red a block ahead of
you, backing-off on the pedal and using the electric motor will give you a
free ride to the light and when you gently brake as you approach the light,
you will recover that energy and possibly more.  While you are sitting at
that light listening to the idling SUVs all around you, hold your breath and
smile.  :-)

I am seeing a lot of 99.9 mpg readings.  I already have been
backing off the gas pedal, starting with my last car.  It
seems like the battery regenerates from coasting too, at least
according to the arrows.  (?)  I do have to learn that braking
is a good thing though.

Thanks for the info re the battery.  That makes sense.  I'll
stop wondering why the lost two bars aren't there.

What I REALLY want to know is what it is doing when there are
NO lines/arrows (and I am not stopped).  I guess that's not as
good as when you are recharging the battery, with that not
coming from the engine.

I have lots to study.  It's clouding up here, so I can now do
it without broiling myself.  This is good....  :-)

No lines at all:  Coasting on a slight downhill incline or with a good
tailwind.  No energy required from ICE or battery to maintain speed, battery
not being charged in order to maintain coast.  Holding it there causes a
cramp in my ankle.

I think I will drive myself crazy looking at that screen and
trying to figure out all the whys and wherefores--and seeing
bars drop and being added.

That instrumentation is a great teaching tool.  After a while you'll feel
the force, Jean.

Well?  Any surprises?  Do you like it?  Are your neighbors suffering Prius
envy?

I don't know whether they have noticed.  Anyway, they wouldn't
understand.  They don't understand my not wanting to use
pesticides and herbicides, so this will be no different.

There are already about 90 miles on the car.  There were 5
when I went for the test drive--and 26 or 36 today.  I don't
know if it went somewhere for its inspection sticker.  At some
point, the calculations got reset, because they are a few
miles out of synch with the odometer.  My average for the
first ca 87 miles was 49.5 mph.  Not bad at all!  I love
seeing those 99.9s!

Very different experience from my W8, as one would expect.  I
think my pleasure with the Prius will be that great mileage
and all those screens to play with!  Also interesting that I
don't have to quite touch the handle of the car to get in.  :-)

My main impression is WHY DID I WAIT SO LONG TO DO THIS?????
It is sweet!  I'll gladly trade my aggressive acceleration for
its virtues.
