I first want to apologize for what's sure to be a large number of questions. Just put a deposit down on a TCH and have more questions than anything else.

1. I know that it will depend on speed, temperature, etc., but just wondering approximately how far the electric motors can drive the car on a flat road, say if you ran out of gas.
2. There is an ECO setting for the AC unit. What does that do?
3. The brochure says the car is XM/Sirius capable, but a footnote adds that it needs a receiver. What exactly does this mean? Do I purchase an XM or Sirius specific receiver that mounts in the dash or somewhere else?
4. I've seen a picture with a display that shows the engine, batteries, electric motor, etc. It shows how energy is flowing (e.g. engine powering wheels, electric motor powering wheels, etc.) Is this display only available with the DVD nav system or is it on all TCHs?

Thanks in advance for all answers.
