Also, no amount of idling will warm up your transmission fluid (automatic), it needs to go thru the gears, to get the oil circulating/warming up.. so once again, driving a little slower/cautious the first few minutes is better then sitting in the garage warming up... plus your just wasting gas.

All info above can be found in the Yaris shop manual.

Thanks for that info. about the transmission. I'll still idle my car for a few minutes till the engines warmed up though before I drive it. I kind of want it for the next 200,000 miles.
