It's an electronic parking brake. Those are common now because a small switch takes up less interior space than a lever for a cable-actuated parking brake, and the computer can disengage the parking brake if it detects that the driver is attempting to drive with it activated. The computer is involved in brake pad replacement to tell the parking brake motor to open to its widest position to accept new pads, and calibrate itself to their thickness.
This requires a special adapter and software subscription rather than a button on the infotainment screen because Hyundai is engaging in rent-seeking and perhaps trying to direct business to its dealers.
So if your brakes go out and you try to use the parking brake for a slow stop it won't do anything anymore?
Correct, though the car in question here is electric and will almost certainly use the motors to slow the car to reuse that energy. The motors should be able to stop the car even if the hydraulic brakes fail, and probably more effectively than a mechanical parking brake.
apparently some do and some don't. or they require a particular cheat code when pressing the button, idk.
the point is, you can't trust your parking brake to be an emergency brake anymore, you press a button and hope something happens
Every vehicle I've had with an electric parking brake operated the same way. Hold the park button while moving and it starts clamping the parking brake down, let off the button and it starts to release. So you can basically PWM the parking brake in an emergency.
~~Capitalism~~ Progress!
Guess I'll add this to the list of reasons I'm keeping my current car until it falls apart.
