304 STARTING AND OPERATING
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the transfer case.
Because four-wheel drive provides improved traction, there
is a
tendency to exceed safe turning and stopping speeds. Do
not go faster than road conditions permit.
Shifting Procedures
2H To 4H Or 4H To 2H
Shifting between 2H and 4H can be made with the vehicle
stop
ped or in motion. The preferred shifting speed would be
0 to 45
mph (72 km/h). With the vehicle in motion, the
tran
sfer case will engage/disengage faster if you momen-
tarily release the accelerator pedal after completing the shift.
D
o n
ot accelerate while shifting the transfer case. Apply a
constant force when shifting the transfer case lever.
NOTE:
• Do not attempt to make a shift while only the front or rear
whee
ls 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.
Dur
ing cold weather, you may experience increased effort in
shif
ting 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
auto
matic 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
leve
r 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 4L is possible with the vehicle
comp
letely stopped; however, difficulty 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
