The "A Off" button in a 2019 Hyundai Santa Fe is used to control the auto start stop system in Your vehicle. This is designed to turn the engine off whenever You come to a full stop to help save gasoline. Many vehicles now come standard with auto start stop on them and this helps reduce the emissions from Your car. If You want to disable the auto start stop system You can press this button and then Your car will stay running whenever You are stopped in traffic or at a red light. This will consume more fuel, but it also can help keep Your A/C system and other accessories running at optimal efficiency.

The 2019 hyundai santa fe a off button is located on the dash.
The a button with the circle around it is located on the middle console. I wish there was some way to permanently turn it off it's a pain in the butt you have to turn it off and constantly I hate it when the car starts jerking when you want to take off after you've been sitting still for a while.
