Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or
uneven tire pressures, excessive vehicle
loading, or cold temperatures.
Shifting effort will increase with speed, this is
normal.
During cold weather, you may experience
increased effort in shifting until the transfer
case fluid warms up. This is normal.
4WD High PT/4WD High AUTO To 4WD Low Or
4WD Low To 4WD High PT/4WD High AUTO
With the vehicle rolling at 1 to 3 mph (2 to
5 km/h), shift an automatic transmission into
NEUTRAL (N), or press the clutch pedal on a
manual transmission. While the vehicle is
coasting at 1 to 3 mph (2 to 5 km/h), shift the
transfer case lever firmly to the desired
position. Do not pause with the transfer case in
N (Neutral). Once the shift is completed, place
the automatic transmission into DRIVE or
release the clutch pedal on a manual
transmission.
NOTE:
Shifting into or out of 4WD Low is possible with
the vehicle completely stopped; however, diffi-
culty may occur due to the mating teeth not being
properly aligned. Several attempts may be
required for clutch teeth alignment and shift
completion to occur. The preferred method is with
the vehicle rolling at 1 to 3 mph (2 to 5 km/h).
Avoid attempting to engage or disengage 4WD
Low with the vehicle moving faster than 1 to
3 mph (2 to 5 km/h).
WARNING!
Failure to engage a transfer case position
completely can cause transfer case damage
or loss of power and vehicle control. You
could have a collision. Do not drive the vehi-
cle unless the transfer case is fully engaged.

The Trac-Lok rear axle provides a constant
driving force to both rear wheels and reduces
wheel spin caused by the loss of traction at one
driving wheel. If traction differs between the two
rear wheels, the differential automatically
proportions the usable torque by providing
more torque to the wheel that has traction.
Trac-Lok is especially helpful during slippery
driving conditions. With both rear wheels on a
slippery surface, a slight application of the
accelerator will supply maximum traction.
STARTING AND OPERATING
On vehicles equipped with a limited-slip dif-
ferential, never run the engine with one rear
wheel off the ground. The vehicle may drive
through the rear wheel remaining on the
ground and cause you to lose control of your
vehicle.
