No. NO. !!! NO !!!
That is a terrible offer, and your dealer should be told
that it makes you suspicious of everything else he will
ever tell you. On priuschat or one of the other forums
you can get 100k/7y for under $k. And check the
warranty on the hybrid system in your state - be amazed.

Read the forums - greenhybrid is a good source.

Not if you install it yourself (voids the warranty).
Those who do so usually find it entertaining only for a
short while. The traction battery stores energy
equivalent to 3-4 ounces of gasoline. THIS IS NOT AN

The electric drive enables the Miller-cycle ICE to
provide acceleration that is acceptable to us (electric
motor has max torque at zero RPM). A Miller-cycle or
Atkinson-cycle engine has terrible low-end acceleration
but great economy once it gets going. The Prius hybrid
drive gives you the benefit of both. We must wait for at
least one more generation of Prius before we can begin
thinking of this as an "electric car charged by an
on-board ICE".

I bought my 2008 Prius with package #2 in January for $2,400 in

Do what makes you sleep well at night. I opted not to buy an extended
warranty on my Prius.

Avoid stopping suddenly as much as possible. Gentle use of the breaks
allows for more time for them to regenerate the battery's power.

Beats me. I have no idea what an EV switch is.

I don't know.

Here in the UK we have the option to extend the warranty at any time up to 3
years old.  I intend to extend mine for 2 years before July, when the car
will be three years old.  UK owners also have an 8 year/100k miles (I
think!) warranty on all the Hybrid components in addition to the 3 year
warranty on the rest.  Given Toyota's reputation for reliability it may be
that the extension of the 3 year warranty for the regular bits might be a
waste of money, but I'm prepared to do this for a couple of years and see
what transpires.

Leave it at home ;-).  Seriously, though, there is a huge set of received
wisdom about tyre pressures, Prius "foot" and general driving style that can
be found here and on other sites (try Priuschat.com) if you really want to
be bothered.  Personally, I find all of this a little tiresome after a while
and it detracts from my enjoyment of the car.  Most of the suggestions are
no different than would apply to any car in terms of fuel economy, so by all
means practice such habits, but I remain doubtful about inflating tyres
beyond the manufacturer's recommended pressures and the so-called Prius
Foot" or pulse-glide technique is simply a pain in the butt for the driver
and those that have to follow.  If I were you I'd just drive it and enjoy
it.  The difference between your gas mileage doing this and doing all the
other stuff as well won't amount to more than a few mpg and I don't reckon
it's worth the bother, considering how much gas you'll likely save in any
case.  The Prius was designed clever to take the grief away from you, the
driver.  Why become an add-on engine management system?

The EV switch does little more than "encourage" the car to use battery
traction when there is a power source choice that doesn't compromise the
Prius battery management systems.  In practice (as has already been said)
this amounts to maybe a mile or so under 30mph on the flat with a trailing
wind and a warm engine.  About the only practical purpose I've found for
mine is to creep away from the house quietly in the early morning and to
arrive quietly late at night.  I still reckon it's only fitted in countries
that have tax laws that are advantageous for alternative fuel vehicles, in
that the EV switch theoretically throws the car into electric traction mode.
Beyond that it has very little practical value in everyday driving.

No.  The Prius battery was never designed to be charged (ie managed) by
anything other than the on-board systems and to attempt to do so would
probably lead to an early death for the battery and give you no measurable
benefit in terms of mpg.  The ICE will run anyway when it's cold, to rapid
heat the exhaust catalyser, thus reducing undesirable emissions more
quickly.  Remember the Prius is a balanced package of innovation that not
only addresses gas consumption but also emissions control.  It's all been
designed to work as an integrated whole and IMHO interference with this very
spohisticated group of systems is unwise.  It is a fascinating piece of
machinery designed to work silently and unobtrusively at minimising your
impact on the environment and dwindling oil supplies.  Be interested in it
by all means, as I am, but after three years I have found that the best way
to treat the car is to just get in it, drive it and enjoy it.

In other words:

this is a gasoline car, people.  The only form of energy that you, the
owner, put into the car is gasoline.  Period.  It is not an electric
car.  Never was, never will be.

Your words Elmo, not mine.  The car generates it's own energy on
deceleration (actually claws back some of the energy used for acceleration)
and converts this to electrical energy stored in a battery.  So, whilst what
you say is true, it is an economical truth in that it doesn't tell the whole
story.  Although it may be a "gasoline" car it is a very efficient one and
gets more work done out of the gas than most other cars on the road, very
comfortably and with some style.  This is it's real attraction.  That it
does this using batteries is incidental.
