How to use the auto start-stop function in Audi Q3?

The usage of the auto start-stop function in Audi Q3 is: Press the auto start-stop button once after each ignition to turn off this function. When the engine is restarted after shutting down, the auto start-stop function will be activated again. Taking the 2021 Audi Q3 as an example, it is a compact SUV with body dimensions of: length 4481mm, width 1848mm, height 1616mm, wheelbase 2680mm, minimum ground clearance 152mm, and curb weight 1570kg. The 2021 Audi Q3 is equipped with a 1.4T turbocharged engine, delivering a maximum horsepower of 150PS, maximum torque of 250Nm, and maximum power of 110kW.

I've been driving an Audi Q3 for almost three years now, and after getting used to the auto start-stop function, I find it quite convenient. It's enabled by default every time I start the car, and I can turn it off by pressing the button with an 'A' on the left side of the steering wheel. When I come to a red light, if I press the brake pedal firmly and hold it for two seconds, the engine shuts off quietly. As soon as the light turns green and I release the brake, I can immediately feel the slight vibration of the engine restarting. It's most practical for commuting in the city—waiting at long red lights does save some money on fuel. However, I always turn it off in heavy traffic, as the constant start-stop jolts can be quite annoying. Before driving through waterlogged areas in rain or snow, I make sure to manually disable the start-stop to prevent water from entering the engine during an automatic restart—this is an important lesson. Also, after two years of driving, I noticed the start-stop occasionally malfunctioning. The mechanic said it was due to an aging battery, and replacing it fixed the issue.

As a commuter who frequently drives in the city, I pay special attention to fuel consumption. The auto start-stop system in the Audi Q3 has helped me save a lot on fuel costs. The system is enabled by default. When the car comes to a complete stop and the brake is firmly pressed, a green 'A' indicator appears on the dashboard, indicating that the engine has shut off. To start moving again, simply release the brake lightly without any additional operations. I've tested it, and during the morning rush hour, stopping at red lights for more than 30 seconds can save about 15% on fuel. However, there are three situations where I turn it off: first, when reversing into a parking space, as the start-stop can cause a delay in power delivery; second, when the air conditioning is on, as the engine shutting down affects cooling; third, when the system automatically turns off due to low battery voltage, which requires a check-up. I recommend flexibly turning it on or off based on road conditions. The central control button is conveniently located next to the handbrake.

The auto start-stop principle is to let the engine rest when the vehicle is stationary. In my Audi Q3, activating it is very simple: the function is enabled by default after ignition, and a green 'A' light on the dashboard indicates it's working. To turn it off, just press the start-stop button located at the lower left of the steering wheel. There are a few key points in practical use: you must press the brake pedal firmly to trigger the engine shutdown; if the air conditioning is set too high or the temperature is extreme, the system may not work; always disable auto start-stop before driving through water, as an automatic restart during water immersion could destroy the engine; it's recommended to turn it off during stop-and-go traffic to reduce jerking. For older vehicles, remember to test the battery during maintenance—if the voltage is insufficient, the auto start-stop will stop functioning.
