I have a 2017 S90 Inscription with the air suspension, but not the 4C chassis. Whenever I park on either a slight up or downhill slope, the parking brake engages. This isn't necessarily a bad thing, but I can't figure out how to turn it off. The owner's manual describes a way to do it that doesn't appear on my touchscreen. Here's what the owner's manual shows: 1. Tap Settings in Top view. 2. Tap My Car Electric Parking Brake and deselect Auto Activate Parking Brake. My "Settings" doesn't have "Electric Parking Brake" as an option in "My Car." According to the manual, the parking brake is supposed to automatically disengage when you are wearing your self belt and shift from Park into reverse or drive, but mine stays engaged. Do you think there's a software upgrade for this?
