Methods to turn off the start-stop function in S90: 1. Locate the vehicle settings in the central control screen; 2. Find the start-stop system settings and click to turn it off. The S90 is a mid-to-large-sized sedan with exterior dimensions of 5090 mm in length, 1879 mm in width, and 1450 mm in height, with a wheelbase of 3061 mm.

I've been driving this S90 for a while now. At first, the auto start-stop function shutting off the engine at red lights took some getting used to. Later, after checking the manual, I found it's quite simple to turn off—just locate the small A button with a circle icon on the left control panel of the steering wheel and press it gently. The button will light up to indicate it's deactivated. You have to press it every time you start the car because the system defaults to on to prevent forgetting to disable it and having the engine auto-start next time. I think frequent start-stops in the city aren't great for the engine, but occasionally turning it off during heavy traffic makes for a smoother drive and helps protect the battery life by reducing constant charge-discharge cycles. It's good to regularly check the button status to avoid accidental operations.

When using this S90 to take my kids to school, I noticed that the start-stop system tends to cause the car to shake on rainy or snowy days, so I usually turn it off immediately after getting in to avoid affecting driving comfort. The button is located on the driver's side of the center console, a physical button with an 'A' letter. Pressing it once lights up the indicator, indicating the start-stop is disabled. One thing to note: if the car has just been turned off and restarted, sometimes it automatically reactivates, requiring manual deactivation again. I think it's important to develop the habit of pressing it every time you get in the car, especially for passengers sensitive to noise. Turning it off makes the car start more smoothly, reducing unnecessary shaking and fuel consumption.

I found the auto start-stop on my S90 quite annoying, so I looked up how to disable it. There's a button with an 'A' logo on the lower left of the steering wheel – just press it to immediately turn off the auto start-stop. You can operate it anytime after starting the car. Note that you'll need to press it again after each restart, and don't forget to confirm the indicator light is on. Keeping it off long-term may save battery and reduce wear, making city driving more comfortable.
