The transfer case provides the following
mode positions:
2H
Two-Wheel Drive High Range — This range is
f
or n
ormal street and highway driving on dry,
hard surfaced roads.
4H
Four-Wheel Drive High Range — This range
maxim
izes torque to the front driveshaft,
forcing the front and rear wheels to rotate at
the same speed. This range provides addi
-
tional traction for loose, slippery road
surfa
ces only.
NEUTRAL (N)
Neutral — This range disengages both the
f
ront
and rear driveshafts from the power-
train. To be used for flat towing behind
a
noth
er vehicle.
4L
Four-Wheel Drive Low Range — This range
p
rovi
des low speed four-wheel drive. It maxi-
mizes torque to the front driveshaft, forcing
t
he f
ront and rear wheels to rotate at the
same speed. This range provides additional
traction and maximum pulling power for
loose, slippery road surfaces only. Do not
exceed 25
mph (40 km/h).
In the event that additional traction is
requi
red, the transfer case 4H and 4L posi-
tions can be used to lock the front and rear
d
rive
shafts together, forcing the front and
rear wheels to rotate at the same speed. The
4H and 4L positions are intended for loose,
slippery road surfaces only and not intended
for normal driving. Driving in the 4H and 4L
positions on hard-surfaced roads will cause
increased tire wear and damage to the drive
-
line components. Refer to “Shifting Proce-
dures” in this section for further information
o
n sh
ifting into 4H or 4L.
When operating your vehicle in 4L, the
engin
e speed will be approximately three
times (four times for Rubicon models) that of
the 2H or 4H positions at a given road speed.
Take care not to overspeed the engine.
Shifting Procedures
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made
w
ith
the vehicle stopped or in motion. The
preferred shifting speed would be 0 to
45
mph (72 km/h). With the vehicle in
motio
n, the transfer case will engage/disen-
gage faster if you momentarily release the
a
ccel
erator 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 and 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 e
xperienced 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
incre
ased effort in shifting until the transfer
case fluid warms up. This is normal.
