How does the auto start-stop button of the XC60 work?

The working principle of the XC60's auto start-stop button is that when the vehicle stops moving due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. Below is some relevant information about the XC60: 1. Exterior dimensions: The length, width, and height are 4688/1902/1658mm respectively, with a wheelbase of 2865mm. 2. Powertrain: The XC60 T4 is equipped with a 2.0T low-power engine, while the T5 features a 2.0T high-power version, delivering a maximum power of 187kW (254PS) at 5500rpm and a maximum torque of 350Nm between 1500-4800rpm. In terms of the transmission system, all models are fitted with an 8-speed automatic transmission.
The working principle of the XC60's auto start-stop button is actually quite simple: when you press that button (usually marked with an 'A' on the center console), it sends a signal to the vehicle's control unit, instructing the system to temporarily deactivate the auto start-stop function. The system itself automatically shuts off the engine to save fuel when the vehicle comes to a stop (such as at a red light or when braking), provided the battery has sufficient charge and the temperature is appropriate. However, if you press the button to turn it off, it remains disabled and won't automatically shut down. Having driven many cars, I find this design allows drivers to control it as needed, such as avoiding annoying vibrations caused by frequent start-stops in traffic jams. Just remember, the system defaults to 'on' at startup, and the button is only a temporary switch; keeping it off for extended periods may impact fuel savings. I recommend using it regularly for eco-friendly driving but adjusting flexibly based on road conditions.
As an XC60 owner, I'm quite familiar with the auto start-stop button: it's a quick toggle switch that disables the engine auto-stop function with a single press, indicated by a small dashboard icon. The system's default operation automatically shuts off the engine when stationary (like holding the brake) to save fuel, but the button overrides this, making the control unit ignore relevant signals. I typically disable it in city traffic to avoid frequent engine restarts at every start-up, ensuring smoother drives; then reactivate it on highways for fuel efficiency. Operation is simply pressing the button - it responds instantly with no accidental activation concerns. Technically, it's electronic: the button sends a command to the vehicle's computer to pause the stop logic. While highly practical, note that a healthy battery is essential for proper system function; occasional malfunctions should be checked at the dealership.
