Where is the Audi One-Key Start Button?

Audi's one-key start button is located on the right side of the steering wheel, and its functions include: 1. No need for the original car key or remote to unlock the doors; 2. Automatic window closing when leaving the car; 3. Beneficial for nighttime driving; 4. Convenient starting with self-check protection for the original starting system; 5. Equipped with car anti-theft functionality. Taking the 2021 Audi A3 as an example, its body dimensions are: 4321mm in length, 1785mm in width, and 1426mm in height, with a wheelbase of 2629mm. The 2021 Audi A3 features a MacPherson strut front suspension and a multi-link independent rear suspension. It is powered by a 1.4L naturally aspirated engine, delivering a maximum horsepower of 150PS, a maximum power of 110kW, and a maximum torque of 150Nm, paired with a 7-speed dual-clutch transmission.

I've been driving Audis for many years, and the most familiar feature is that start button. When you get in the car, don't rush to look for the keyhole - Audi long abandoned traditional ignition methods. The one-touch start button is usually located on the instrument panel to the right of the steering wheel, while some models position it in front of the gear shift lever. That round silver button with the engine icon is particularly eye-catching. The designers put considerable thought into this placement - your right hand can reach it without leaving the steering wheel, making it extremely convenient while driving. Remember you must press the brake pedal when starting, otherwise pressing the button will only power up the electronics without starting the engine. When I first drove an Audi, it took me some time to find it too, but later I noticed the button glows slightly in dim lighting. Newer models now even add tactile vibration feedback. This design is far more convenient than old-fashioned keys - you don't even need to take the key out of your bag.

A few days ago, my neighbor couldn't find the start button on their newly purchased Audi and asked for my help. Actually, Audi's start buttons are all within easy reach of the driver's seat, with 90% of models placing it at the lower right side of the steering wheel, in the area between the instrument panel and the steering wheel. This position is ergonomically designed so your arm naturally falls onto it. If you can't find it, just look down—it's usually made with a metallic finish and features a ring-shaped backlight. Note that there might be slight variations depending on the model year; for example, the A4 might have it in front of the gearshift, while the Q7 might place it closer to the instrument panel. To start the car, press and hold the button for two seconds while keeping your foot on the brake, and you'll hear the engine start. If the button doesn't work, check the smart key's battery, though in my 20 years of car repair, I've only seen this happen two or three times.

Last week, I finally figured out the location of the one-touch start during an Audi test drive. The salesperson pointed to the lower right side of the steering wheel and said, 'See that metal button with the engine symbol? It's less than ten centimeters from the instrument cluster, and your right hand can naturally reach it.' Later, I found out that Audi placed the button there for safety—to avoid the distraction of looking down for it while driving. It's super easy to use: just press lightly while holding the brake, much faster than inserting a key. At the auto show, I noticed the new model adds red ambient lighting around the button, making it more visible at night. I heard older Audi models didn’t have this feature, but now even the A3 comes with it as standard.
