But you stepped out of your car, so it "shut off" while you ran in. For me, it triggers auto-open/close once after every "startup". So had you simple pulled up, it auto-opened, and a passenger went inside (so you never got up and out to turn off the car), it likely would not have auto-closed.
My theory is the logic works as follows:
- Car must be on (so if car is in garage, this doesn't get ready until you hit the brake/out it in gear)
- Every time the car turns on, set "able to trigger auto-Homelink" to TRUE
- If GPS triggering Homelink popup says car is at home when first turn on, use text "Auto-Close". Else, use text "Auto-Open" when Homelink popup is triggered
- Once countdown hits 0 and auto-open/close is trigger, set "able to trigger auto-Homelink" to FALSE
This likely is missing some detail due to limited experience, but it is the behavior my car exhibits.
