Operating Instructions


  1. Relax the throttle - no acceleration or deceleration.
  2. Shift the transfer case to desired 4x4 mode.
  3. Press the button and pull the cable into full engaged position. (Light on-off throttle action will help align gears for smooth engagement.)
  4. Release the button.


  1. Place transfer case in 2WD mode.
  2. Press the button, push the cable into full disengaged position, and release the button. If moving, light on-off throttle action will help to relax the drive train. Disengagement may be easier with some models if the vehicle is stopped and put into reverse for a few inches while pushing the cable in.


  1. 2WD Lo-range–Place the transfer case in 4WD Lo range, but do not engage the 4x4 Posi-Lok system. Warning: Do not apply excessive torque in this mode.
  2. If a differential gear locker is used in the front axle, the driver can manually unlock the front axle to make very tight right turns on hard ground, then re-lock to continue.
