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. The S90 is equipped with an 8-speed automatic transmission and a 2.0L turbocharged engine, delivering a maximum horsepower of 250 hp, a maximum power of 184 kW, a maximum power speed range of 5400 to 5700 rpm, a maximum torque of 350 Nm, a maximum torque speed range of 1800 to 4800 rpm, and utilizes direct fuel injection.

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 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 and reduce wear, making city driving more comfortable.

The start-stop function in my S90 is quite fuel-efficient, but the frequent engine shutdowns at low speeds can be a bit uncomfortable. So, I've developed a habit of turning it off right after getting in the car. The button is located below the dashboard, marked with an 'A' letter—just press it lightly. It defaults to 'on' every time the car starts, so I recommend disabling it immediately to ensure it stays off. Leaving it on for extended periods might have a minor impact on the car , but maintaining battery health through regular use should suffice for daily driving.

As a owner, I have some experience with the start-stop system. Turning it off is quite simple – just locate the 'A' button in the central control area next to the driver's seat and press it to temporarily deactivate the start-stop function. The system automatically reactivates when you start the car again, so you'll need to manually turn it off each time you drive. Although the system is designed for fuel efficiency and environmental protection, deactivating it in urban traffic can reduce noise and vibration, making for a more comfortable drive. Just remember to check the button status regularly to avoid accidental activation that might affect your driving experience.
