STARTING AND OPERATING 211
positions at a given road speed. Take care not
to overspeed the engine.
Proper operation of four-wheel drive vehicles
dep
ends on tires of equal size, type, and circum-
ference on each wheel. Any difference will
a
dv
ersely affect shifting and cause damage to
the transfer case.
Because four-wheel drive provides improved
tra
ction, 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 stopped or in motion. The preferred
shifting speed would be 0 to 45
mph (72 km/h).
Wit
h 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
inc
reased 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
N
EU
TRAL (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
tra
nsfer 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 4L is possible with the
veh
icle completely 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 vehicle rolling at 2 to 3
mph
(3 to 5 km/h). Avoid attempting to engage or
dis
engage 4L with the vehicle moving faster
than 2 to 3
mph (3 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
vehicle unless the transfer case is fully
engaged.
