How do you check the sleep mode on a BMW x3?

To check the sleep mode on a BMW X3, you can look at the vehicle's dashboard display. When in sleep mode, the display typically dims or goes off entirely after a period of inactivity. Additionally, you can verify if the vehicle is in sleep mode by attempting to access features like the navigation or infotainment system; if they do not respond, the car is likely in sleep mode. Finally, refer to the owner's manual for specific details related to your model year.
