Remove your bracketed "and?", and it makes sense.

1.  If the interior lights and personal lights are on when the door is not
fully closed, they will go off automatically after 20 minutes.

2.  If the interior light switch is in the door position and the door is
not fully closed, the interior light will go off after 20 minutes.

Having done this in my 2010, I know for certain that:

If the interior light is on (the one above the console) and the door is
closed, that light will stay on indefinitely.  Fortunately I caught mine in
this state after only an hour and the battery in my 2010 still had enough
juice to power-up the starting system.

So far so good.



Yup.  Just like my Honda.  Stupid, ain't it.

With other cars that use standard size 12v batteries, you can buy
batteries that shut themselves down before they're all the way out.

The ONLY way they're connected is that the car needs the 12v battery to
turn on the car, which means engaging the drive system (and its
integrated electrical component).  If the 12v battery goes dead, the
relays that turn on the drive system don't open.  The drive system is
isolated and drains no energy, either from its gasoline component or its
electrical storage component.

Charge up your 12v battery, or put in a new one, and it will turn the
car on and close the relays that engage the electrical component of the
drive system.  No problem.

Now:  should you leave the car turned ON, and you leave lights on, and
then it runs out of gas, you will exhaust the entire drive system, and
it will turn off.  Then the 12v battery takes over, and then IT
exhausts, and you have nothing left in the system whatsoever.

This is just like any other car.  Any GM would do the same thing.

It would pay for you to examine just how your car works before making
incorrect assumptions and statements.




Not at all.  You put a battery charger to it.  You DO mean the 12v
battery that the user interfaces with, right?  Because that's the ONLY
battery you interface with, the ONLY battery you would be charging.

Again, read up on your car if you're interested.  You'll find that the
traction battery (which the user never interfaces with) is charged when
the car is delivered to the dealer.  Should the dealer service dept have
to replace a traction battery (let's say there's been an accident),
there's a unique machine that travels to that dealership to support
charging the traction battery after a new one has been installed.

It's not as simple as "turn the car on and let it do its thing".



The 12v battery, you mean.  I agree.  My Honda has a system that turns
off interior lights after 5 minutes of leaving the door open.  You have
to pay for the top trim level to get that, though--and if you use the
pushbuttons to turn on the interior lights, it leaves them on
regardless.  When you have kids playing around in a van, that's going to
happen.  Sucks.  It's not rocket science to fix that--but neither Honda
nor Toyota has bothered.



ummmmm....yeah?  So?  If you stick a knife in your eye, you'll hurt
yourself.  I can go on and on stating the blindingly obvious.  Why is
this a problem in your universe?




you know, if you're going down the highway at highway speeds and you cut
the wheel 180 degrees, you're going to have an accident and involve
other people on the road as well.  Why is any of this a problem for you?

If you're uncomfortable with the fact that PHYSICS WORKS, maybe you
should sit home in a plastic bubble.




Sure, it could be better.  On the other hand, a reasonably intelligent
person--say, someone who actually has $5K to spend on a car--won't have
any problems getting through it.




And everyone benefits.

He's right about item 0.

The batteries are not interconnected, and there's no way they could be.
The batteries running the drive system are 280V at very high current.
Every bulb in the car would probably explode at that voltage, and so would
the 12V battery if exposed to this voltage. Hopefully, this person won't
go running out to his Prius to try to conect one system to the other. If
he does, I hope his insurance is paid up...

AAMOF, there is an exact procedure for disconnecting the drive-line
batteries from the system, and has to be done in the proper order or the
batteries will explode, the person will be fried, the driveline ruined or
all three.
