Driving Shifting from 4x4 HIGH to 2WD Rotate the 4x4 control to 2WD at any forward speed. Disengagement of the transfer case and front hubs may be delayed due to torque bind which is caused by driving on dry hard surfaces or performing tight turns while using the 4x4 system. • You do not need to operate the vehicle in R (Reverse) to disengage your front hubs, but it will eliminate any torque bind and allow the system to immediately disengage. Shifting from 4x4 HIGH to 4x4 LOW If the range shift requirements are not met, the 4x4 Low indicator will flash continuously. 1. Bring the vehicle to a complete stop. 2. Place the gearshift in N (Neutral). If the vehicle is equipped with a manual transmission, also depress the clutch pedal. 3. Move the 4x4 control to the 4x4 LOW position. 4. Hold the shift conditions until the 4x4 LOW indicator light illuminates. 5. If the 4x4 LOW indicator light flashes continuously for more than 10 seconds, allow the vehicle to move at a speed below 5 mph (8 km/h), then repeat steps 2 through 5 while the vehicle is rolling before reporting any shift concerns to your authorized dealer.
