Running a checklist
Go step by step, in order. Critical steps ask you to confirm; finishing turns the banner green.
Step by step
Check off or skip each step in order. A step that depends on an earlier one waits its turn until that one is done.
Critical steps
Some steps — like the black tank valve — are marked critical. They need a confirm, not just a tap. Skip one, and the banner turns red so you don't drive off and miss it.
You can turn a step critical, or write the question the hands-free walk-through asks for it, in the step editor — see Adding, changing, reordering and deleting steps.
Finishing
Finish every step, and the banner turns green and says so.
Run history shows who checked each step, by the name you set in Settings › Your name (or a device name, if you haven't set one). If you check something by mistake, Undo brings it back.
