NOTE:
Do not attempt to make a shift while only
the front or rear wheels are spinning. The
front and rear driveshaft speeds must be
equal for the shift to take place. Shifting
while only the front or rear wheels are
spinning can cause damage to the transfer
case.
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.
4H To 4L Or 4L To 4H
With the vehicle rolling at 2 to 3 mph (3 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 2 to 3 mph (3 to 5 km/h), shift the
transfer case lever firmly to the desired posi-
tion. 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 trans-
mission.
NOTE:
Shifting into or out of 4L 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 2 to
3 mph (3 to 5 km/h). Avoid attempting to
engage or disengage 4L with the vehicle mov-
ing faster than 2 to 3 mph (3 to 5 km/h).
WARNING!
Failure to engage a transfer case position
completely can cause transfer case dam-
age or loss of power and vehicle control.
You could have a collision. Do not drive the
vehicle unless the transfer case is fully
engaged.

tions:
2H (Two-Wheel Drive High Range)
4H Auto (Four-Wheel Drive Auto High Range)
4H PT (Four-Wheel Drive Part Time High Range)
