New Prius Taxi Owner

Eugene Oregon has its first hybrid taxi!
Its actually my first hybrid also. I just bought a 2007 Prius. I am sure I will have lots of questions. I have been lurking for a few month hoping and saving to upgrade from my Previa.
First question, How do I know what package it is? The last owner didnt know. It has leather seats, Nav, backup, 6 disk cd, some freaky little calendar that doesnt alert me to any of the things I put in it, bluetooth, some great lady that asks me questions, but never understands what I am saying, HID lights, ummm... I think thats it.
Its got 61k miles, and drives like its new, so I think it will make a great Taxi.
Taxi owners -
How often do you change fluids and with what? Same with tires and brakes.
I've got a centrodyne 610 meter, is there anything I need to tell the install guy other than where to put it.
Where is a good place, on top of the monitor seems very high and would restrict vision.
Other than the car, what has been the best advertising strategy to get your number out there as being Hybrid?
I just read a nation poll that ranked Eugene as having the most Prius per capita than any other city in the US. That will either be a good thing or a bad thing, I dont know yet.
Is there anything I should do to the car to help with all the abuse and miles it will get?
Any other pointers? I have been in the taxi business for 5 years, use to own a fleet of 12 Previa but sold it to my biggest competitor with 14 Previa. Now I am just working for a small outfit with three single owner/driver cars. Our goal is to provide better service and better cars than anyone in town since its just us driving we have total control over the passengers taxi experience. We'll see how this works out, its a completely different business model than any of us has tried before.

 

Its all factory.
15in wheels. Is that the only difference between touring?
I also have to go to the dealer for the SKS. The only key I got with the car works harder not smarter, and doesnt open the doors either.

 

Thanks for the reply. No service guide. I got no paperwork with the car, and one non-working smart key.
I look into how to change the transaxle fluid, see if I can do it easily and quick before I take it to a lube store. I've never heard of a mirror meter. We are pretty limited on taxi tech here. The Centrodyne is top dog, only after the new MDT's that the company I use to work for just got. Man that was a nice change from radio dispatch. I hate to go back. If I didnt already have a new Centrodyne here, I would look into the one in the mirror it sounds cool. I am thinking of hooking up some kind of arm from the passenger side floor for it to mount on. That may not work though, too many 300 lb people have to sit in the front seat with me.
BTW- I just put my first 200 miles on the car and decided to go fill up. When it only took 2 gallons, I made the gas attendant try to put more in! 50 MPG will be very easy on the bottom line.
