When to turn on auto 4 wheel drive?
The “AUTO” setting will cause it to automatically engage the 4wd when it detects slippery conditions.

How does a four wheel drive system work?
Locking Hubs. To engage four-wheel drive, the driver actually had to get out of the truck and turn a knob on the front wheels until the hubs locked. Newer systems have automatic locking hubs that engage when the driver switches into four-wheel drive. This type of system can usually be engaged while the vehicle is moving.

What is the actuator on a 4 wheel drive?
The actuator is a component found mostly on modern four wheel drives and is designed to electronically engage 4 wheel drive. It accomplishes this by means of a small electric motor bolted onto the transfer case that shifts a pin in place to lock the center transfer differential.
