New high mile driver questions

[firebob]

I got a 09 Yaris (18 miles) 3 weeks ago. I did lots of internet searching before I got it and decided it would be the best thing for my needs. I’m sitting at 4700 miles and have some questions but don’t think I should make multiple threads for what should be simple stuff.


1. On cold days there is a green temp light that comes with start ups and stays on for about a 3 minutes or so then turns off. It has been -0* if that makes a difference. Do I need to get them to look at something?
2. I would love a set of seat covers and have air bags in the seat. I want fitted covers made for airbags. I have found some on ebay but want to know if others are out there. I don’t want leather and I’m more looking for protection of the seats then to dress it up.
3. It’s going into the shop on Monday for its first time for oil / filter change. But I was thinking about getting the trans oil done. I know how the wet disks are made and how much left over will end up in the trans form there making. Most months I drive 5500 to 6500. I know there’s no filter in the trans but was thinking it might help out in the long run.
