Short answer = yes
Long answer from cars.com ...
"The manual has permanent 4WD for use on any surface, with a limited-slip center differential that sends 60 percent of the torque to the rear axle in normal driving. It can automatically transfer up to 70 percent back there, or a maximum of 53 percent to the front axle when slippage occurs.
The transfer case lever can be used to lock the center diff for a 50/50 split, and to engage an additional low gear for off-roading. In normal use on snow and wet pavement, automatic mode should be more than enough. The 50/50 lock might help when stuck and in low gear.
The 4WD that's teamed with the automatic transmission is actually less sophisticated. Rear-wheel drive is the default mode. Here the transfer-case shifter engages a
part-time, 50/50-split 4WD that's for use only on slick surfaces. (Dry pavement causes binding and possibly damage.) Another setting engages the low gear for off-roading. A locking rear differential, controlled by a dashboard button, is optional."

also, they only mention locking rear diff with the auto trannys, but it's available on both.
