They may damage the hood. You should first put them into the maintenance position. Do so by powering off the car, then within 10 seconds hold the wiper switch in the MIST position for at least 2 seconds (source: 2020 manual, p. 604). When done, turn power on and hold the wiper switch in the MIST position until both wiper arms return (p. 606).
You need to lock it by pressing the “lock” button on the key, or touching the ridged part at the top of the front door handles (using two fingers works best), or pressing the button inside the tailgate handle.
The car knows to apply the “home” charging schedule by checking the “home” location you’ve set in the built-in satnav. If you don’t set one, it won’t apply this schedule.
If you e.g. want your car to charge 00:30 to 04:30, the schedule should start at 04:30 and end at 00:30.
The car likely came with “locking wheel nuts” – there will be one specially keyed nut on each wheel. It should also come with the unique key for these wheel nuts. Keep this key in the car as you’ll need it in case of a puncture. For a new car, the key may be in a box in the glove compartment together with the replaced regular wheel nuts.
In this test (via this page), the Honda e Advance could go another 31.8 km (19.8 miles) after showing 0% state of charge. It’s likely bad for the battery to do this regularly, but could be good to know in an emergency situation.
