What does it mean when the Buick Envision prompts that the four-wheel drive is turned off?

Buick Envision prompts that the four-wheel drive is turned off means that the current driving conditions do not require the four-wheel drive mode, and only two-wheel drive is needed. Taking the 2020 Buick Envision as an example, its body structure is a five-door, five-seat SUV, with body dimensions of: length 4694mm, width 1839mm, height 1686mm, wheelbase of 2750mm, and a fuel tank capacity of 66l. The 2020 Buick Envision is equipped with a 1.5T inline 4-cylinder turbocharged engine, with a maximum horsepower of 169PS, a maximum power of 124kW, and a maximum torque of 250Nm.
If my Envision's dashboard displays a 'Four-Wheel Drive Off' warning, I would assume it's alerting me that the AWD function has been deactivated, either manually or due to a malfunction. Possible causes include accidentally pressing the mode switch button—there's a selector near the steering wheel that can turn off 4WD if bumped—or a faulty sensor sending false signals. Alternatively, there might be an issue with the drivetrain module, such as a computer control error or a loose connection. In this situation, I would first pull over and check the settings screen to see if it shows 2WD mode; if so, I’d try switching it back. If restarting the car doesn’t resolve it, I’d visit the dealership for diagnostics, as driving with 4WD disabled increases the risk of slipping in rain or on muddy roads. On a related note: the AWD system normally enhances traction, especially during turns, so don’t delay repairs. Having technicians test the AWD function during routine maintenance can prevent such warnings—addressing issues early is safer and more cost-effective overall.
