From the manual for my 2013
Use the following procedure to prepare your vehicle for normal usage.?
1. Bring the vehicle to a complete stop, leaving it connected to the tow vehicle.
2. Firmly apply the parking brake.?
3. Turn the ignition switch to the LOCK/OFF position.?
4. Turn the ignition switch to the ON/RUN position, but do not start the engine.
5. Press and hold the brake pedal.?
6. Shift the transmission into NEUTRAL.?
7. Shift the transfer case lever to the desired position.
With all that said, my transfer case is a bear to get from neutral to 2H. Sometimes, I'll drop it into 4L and continue with the disconnect. Then, I'll drive it a few feet, put the transmission in Neural and then shift to 2H. It seems to work more smoothly this way.
