On my 3.0R there is no way to have it pre-select outside air when on full auto, but it always goes to using outside air once it's close to the set temperature.
One thing that's not obvious is that you can manually change one feature such as the outside air intake, and the temperature and fan speed etc are still under auto control. On gripe I have is that the Aircon is always on, even when it's 40F outside.
