Another couple questions on the 2008.
Owners manual doesn't quite explain this that I've been able to find yet.
On the anti theft system, why would the light blink when the car is turned
off but I'm still sitting in it (looking up something in manual) & the doors
aren't locked? It says to turn off unlock doors or start car?
Also, it did mention that there may be noises when shutting down/starting
from the transmission, etc. It's off & I'm still in it when it sounds for a
seconds that something is running, I'm assuming this is normal?

It's telling the world that the key is not in the ignition, and
therefore the ignition will not activate no matter what.

It's not a door lock thing.  It indicates that the ignition security
system is active.

After you power the car off, the system pumps coolant into a vacuum
bottle to keep it warm (this helps with emissions when the car is

The noise you're hearing is the pump.

Also, during driving you'll hear noises that correlate with your use of
the brake pedal.  That is the brake pressure accumulator, and is
perfectly normal.

Don't be bugged by the security system light blinking when the car is turned
off.  That's common to many cars including my old 1994 Volvo.  The light is
an LED and uses a tiny amount of energy.

One thing we learned about our 2006 Prius though when we left the car parked
for several weeks is to turn off the switch (near the steering column) that
powers the remote key system.  The battery (the small one in the rear, not
the power battery) was flat when we tried to start the car and we needed a
jump start to get the car going.

a) that's one reason it's nice to have a simpler car, like my Prius
without that

b) fortunately, you really only need flashlight batteries to "jump" the
Prius into opening the relays and activating the 201v electrical system.
