Presence warnings
By default, your car alerts you if it detects that passengers or pets are still in the car when you try to lock it. When this happens, your car will not lock and you'll receive a notification in the centre display. However, it's possible to lock the car with a passenger inside if you've temporarily allowed occupant locking in the locking settings.
Warning
Volvo recommends not leaving people or pets in a locked car.
Some regions have laws prohibiting people or pets being left inside a locked vehicle.
