The "button" that controls Auto S/S is just above the HVAC controls and is readily available to be pressed when the car starts.That's ridiculous! Who wants to scroll through all those menu items every time they start the car!
The Infotainment system will be nearly identical to the one in my Outback, and while it's not perfect, it's been greatly improved with updates. Turning off Auto S/S is now part of my start-up habit (put on seatbealt, deactivate parking brake, check mirrors, select music, etc) while I wait for the engine/CVT to get their fluids flowing and a bit warmed up.
I always deactivate Auto S/S in winter as the heated seats/wheel limit the shut off time to a dozen seconds or less. In the summer I'll use it on occasions where I'll be stopping infrequently, or where I know the lights are long.
