a few stupid questions

[anyyan]

Hi all. I'm not sure if this post deserves to be in the technical forums, since the questions in it are pretty basic. I'm a complete idiot when it comes to car, so there. A new co-owner of an automatic transmission 2006 Yaris. I've driven cars before but this is the first time that the car is really owned by me.

* What does the Cool sign in the dashboard mean? Is the normal condition for this sign on or off? When I first start the car from cold, should I wait until the Cool sign is off?

* I'm still not sure what to do should my car suddenly go dead in the middle of the road. Will I be able to push it, with the transmission not in the neutral position?

* I don't use the car everyday, but do I still have to warm it, a la the traditional cars? Or is once a week enough?

Thanks in advance!
