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
2WD High To 4WD High Or 4WD High To 2WD
High
Shifting between 2WD High and 4WD High can
be made with the vehicle stopped or in motion.
The preferred shifting speed would be 0 to
45 mph (72 km/h). With the vehicle in motion,
the transfer case will engage/disengage faster
if you momentarily release the accelerator
pedal after completing the shift. Do not
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 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.
4WD High To 4WD Low Or 4WD Low To 4WD
High
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.
