How does Auto 4WD work on the Silverado? The Auto 4WD system on the Silverado is designed to automatically engage and disengage four-wheel drive mode based on the traction and road conditions.

Driving in 4WD AUTO means automatically switching between 2WD and 4WD whenever the vehicle determines it needs to. For this system to work, your car’s transfer case must have a differential between the front and the rear, which allows the front and rear axle to rotate at different speeds when going around a corner.
