edit, from above doc :
Outside temperature sensor: Autostop is prevented if:
Outside temperature is lower than -16 C (3F)
Outside temperature is higher than 82 C (180F)
NOTE: The temperature limits that have been set on the outside temperature sensor are
extreme and therefore must always be considered .
ATC: Autostop is prevented if the difference between the climate control temperature set by the
customer and the temperature inside the passenger compartment is greater than 4C (39F)
If the outside temperature is > 180F the start/stop status would be the least of your worries! I wonder if they really mean that.

Who knows, however, if the car is sitting stationary in the sun I could imagine the outside temp gauge will indicate quite high temperatures....

Having it on the coldest setting won't make it cool any faster. This is like ladies (sorry but true) that want house at 72 but crank it to 80 thinking it will heat faster. Has to go by 72 on way to 80....Max with recirc only quicker if inside temp cooler than outside. Now cranking the fan may work IF you have enough effective cooling surface on evap to not overwhelm it with excessive volume. 99% of the time on any of my cars, i leave it in auto...works for me. Why is it these folks are also the ones that want AA or Apple whatever....realize I am bustin here.
