There is a circular button behind the gear lever of the Audi, which serves as the home return button. Here are the functions of other buttons in the Audi: Electronic Stability Program (ESP): It is enabled by default and generally not recommended to be manually turned off by the driver. This system effectively prevents the vehicle from losing control during extreme driving conditions. Hazard Warning Lights (commonly known as double flash lights): Used in special situations such as vehicle breakdown or temporary parking, primarily to alert other vehicles. Volume adjustment buttons: In addition to the normal knob for adjusting volume, moving it left or right can also switch songs.

Just helped my sister figure out her new A4L a couple of days ago. The current MMI system's return operation is mainly handled via the rotary knob area near the gear lever. See that small arrow button at the top left of the knob? The one with backlighting is the home return key. Press it once to go directly back to the main interface, and hold it down to activate the voice assistant. If the central control has been upgraded to the latest touchscreen version, there will be a floating house icon in the upper right corner—clicking that works too. Personally, I find the physical button on the rotary knob more convenient, especially when driving, as you don’t need to look down to find it. Also, a heads-up: the return button is quite close to the drive mode button, so be careful not to press the wrong one by mistake.

Having driven the A4L for three years, the return button is located right where your right hand touches the control knob area. Look down at the center console—the silver circular knob's top-left corner has a button marked with a left arrow. Pressing it takes you straight back to the main menu with clear tactile feedback. For higher-trim models with touchscreens, you can also tap the small home icon on the far right of the status bar at the top of the screen. In real-world use, the knob button responds slightly faster than the touchscreen, especially when wearing gloves in winter. Note: the button has a matte finish, so avoid getting oils on it—last time I smudged it with milk tea fingerprints and had to wipe it for ages.

The current Audi A4L offers two ways to return: hardware and software. The physical button is located at the upper left of the MMI knob area, marked with a return arrow. On the software side, it's the house icon on the far right of the navigation bar at the top of the 10.1-inch touchscreen, which serves as the home button. Using the physical button is recommended as it triggers 0.3 seconds faster than the touchscreen. Important note: Operating the screen for more than 3 seconds while driving will trigger an alarm, so it's advised to use the knob buttons. An unexpected discovery: holding the return button for 2 seconds brings up the background app list.

Hey! Last time I almost turned off the air conditioning while searching for the return button in my friend's A4L. Remember this location: the mouse-like knob next to the gearshift with the "↩" symbol in the upper left corner—that's the one! Press it to instantly return to the main interface, faster than flipping through your phone. For the touchscreen version, pay attention to the small house icon in the upper right corner, but it's prone to accidental touches in rainy weather. The knob button is actually quite refined, with metal edging and haptic feedback. Last time, the car washer scrubbed this spot really hard, so owners should remind them to press gently.
