Oops, apparently I didn't state my case properly.

Auto stop works fine, after about 10 miles with the heat on it stops every time, it just takes longer to warm the car up on cool day (10 miles) than I drive to & from work (6 miles).

I was frustrated because when it is 90 outside, I get Auto stop within a few blocks, now that it is cooler, it is taking me several miles to get it to work.....the heater is drawing heat off the engine therefore making the car take longer to warm up completely.

I am not saying the auto stop does not work, just not as quickly as when it is warm out.

does that make better sense?
