WHEN TO USE "DISENGAGE", OR "ENGAGE"' POSITION:
Use "DISENGAGE" for all driving that does not require four-
wheel drive power and traction.
Use "ENGAGE" whenever four-wheel drive is used.
To avoid excessive torque loads on the rear axle, DO NOT
drive vehicle in low range of transfer case with locking hubs
set in "DISENGAGE" position.
For the first 320 km (200 miles) operate your new vehicle with
the locking hubs in "ENGAGE" position to assist in initial
break-in of the front driving axle. Place transfer case control
in 2-wheel drive position.
DO NOT DRIVE unless controls on both hubs are set properly
and both are set the same!
Always shift transfer case to 2WH before attempting to
disengage locking hubs.
