What is the small button inside the Audi R8 storage compartment for?

[DiAmy]

A small button inside the Audi R8 storage compartment is the P button, the parking button. Introduction to the P button: The P button can be pulled up or pressed down. It is similar to a traditional handbrake lever: pulling engages the brake, while pressing releases it. After pulling the P button, a red (P) indicator will appear on the dashboard, equivalent to the original handbrake braking. This P function must be manually activated. To release it manually, you need to press the brake pedal and push the P button downward. The P button can also be released by applying throttle: when the handbrake is engaged, if the car is in a driving gear (D, R, S), all doors are closed, and the seatbelt is fastened, applying throttle will automatically release the P function. Introduction to the A button (Auto Hold): The Auto Hold switch. The A button can only be pressed downward. It is a stateful button, similar to the AC (air conditioning) switch. Pressing it once turns on Auto Hold, indicated by the A button's light, and pressing it again turns it off. When Auto Hold is enabled, the car will automatically stop after braking to a complete halt in any gear, displaying a green (P) indicator on the dashboard. At this point, releasing the brake pedal will not cause the car to move. If you don't need to wait for a long time, there's no need to shift to neutral. If the car is in a driving gear (D, R, S), pressing the throttle will allow it to move. The purpose of Auto Hold is to eliminate the need for any manual actions from stopping to starting. It is a very useful feature during traffic lights or congestion. Therefore, the A button is not one that needs to be pressed frequently, nor should it be pressed after the car has come to a complete stop.
