Power Take-Off (PTO)
If your vehicle is equipped
for the addition of a PTO,
this factory installed
switch will be located in
the instrument panel.
When the PTO switch is in the ON position, engine
speed is limited to maximum PTO speed if PTO
is activated during driving; therefore limiting overall
vehicle speed.
Before using a PTO, refer to the manufacturer’s or
installer’s instructions.
Four-Wheel Drive
If your vehicle has four-wheel drive, you can send your
engine’s driving power to all four wheels for extra
traction. To get the most satisfaction out of four-wheel
drive, you must be familiar with its operation. Read
the part that follows before using four-wheel drive. You
should use two-wheel drive high for most normal
driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of time
may cause premature wear on your vehicle’s
powertrain. Do not drive on clean, dry pavement in
four-wheel drive for extended periods of time.

Locking Hubs
Turn the dial of the hublock (A) from the “Free” position
to the “Lock” position to lock the front axle.
Turn the dial of the hublock (A) from the “Lock” position
to the “Free” position to unlock the axle.
You do not have to back the vehicle up to disengage
the hublocks.If your vehicle is equipped
with four-wheel drive, the
transfer case knob is
located to the right of the
steering wheel on the
instrument panel. Use this
knob to shift into and
out of four-wheel drive.
An indicator light will show you which position the
transfer case is in. The indicator lights will come on
briefly when you turn on the ignition and one will stay on.
If the lights do not come on, you should take your
vehicle to your dealer for service. An indicator light will
flash while shifting the transfer case. It will remain
illuminated when the shift is complete. If for some
reason the transfer case cannot make a requested shift,
it will return to the last chosen setting. Hublock Dial Location

m(Two-Wheel High):This setting is for driving in
most street and highway situations. The transfer
case does not drive the front axle in two-wheel drive.
The front-axle will spin if the front wheel hubs are
locked. Be sure to unlock the hubs to achieve the best
fuel economy.
4
m(Four-Wheel High):Use Four-Wheel High when
you need extra traction, such as on snowy or icy
roads or in most off-road situations. Be sure the front
wheel hubs are locked when you want to drive in
Four-Wheel High.4
n(Four-Wheel Low):This setting sends maximum
power to all four wheels. You might choose Four-Wheel
Low if you are driving off-road in deep sand, deep
mud, and climbing or descending steep hills. Be sure
the front wheel hubs are locked when you want to drive
in Four-Wheel Low.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be injured. If you are going to leave
your vehicle, set the parking brake and shift
the transmission to PARK (P) and make sure
the transfer case is in a drive gear.
Notice:If your vehicle has an Allison
®transmission
and you try to put the transmission in PARK (P)
while the transfer case is in Four-Wheel Low,
the transmission may not go into PARK (P) and
could damage your vehicle. When parking your
vehicle, make sure the transfer case is in Two-Wheel
High or Four-Wheel High.
NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.

Shifting Into Four-Wheel High
Turn the knob to four-wheel high. This can be done at
3 mph or less and when you are shifting out of
Four-Wheel Low. The indicator light will flash while
shifting. It will remain illuminated when the shift
is complete.
Shifting Into Two-Wheel High
Turn the knob to Two-Wheel High. This can be done at
3 mph or less and when you are shifting out of
Four-Wheel Low.
Shifting Into Four-Wheel Low
To shift to Four-Wheel Low, the vehicle’s engine must
be running and the vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission
in NEUTRAL (N). The preferred method for shifting
into Four-Wheel Low is to have your vehicle moving
1 or 2 mph (1.6 to 3.2 km/h). Turn the knob to
Four-Wheel Low. You must wait for the Four-Wheel Low
indicator light to stop flashing and remain illuminated
before shifting your transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel Low indicator light has stopped
ashing could damage the transfer case. To
help avoid damaging your vehicle, always wait for
the Four-Wheel Low indicator light to stop ashing
before shifting the transmission into gear.If you turn the knob to Four-Wheel Low when your
vehicle is in gear and/or moving, the Four-Wheel Low
indicator light will flash for 30 seconds and not complete
the shift unless your vehicle is moving less than
3 mph (4.8 km/h) and the transmission is in
NEUTRAL (N). After 30 seconds, the transfer case will
return to the setting last chosen. If your vehicle is in
gear and moving less than 3 mph (4.8 km/h), the
transfer case will shift to Four-Wheel High.
Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High or
Two-Wheel High, your vehicle must be stopped or
moving less than 3 mph (5 km/h) with the transmission in
NEUTRAL (N) and the engine running. The preferred
method for shifting out of Four-Wheel Low is to have your
vehicle moving 1 or 2 mph (1.6 to 3.2 km/h). Turn the
knob to Four-Wheel High or Two-Wheel High. You must
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop flashing and remain illuminated
before shifting your transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel High or Two-Wheel High indicator
light has stopped ashing could damage the transfer
case. To help avoid damaging your vehicle, always
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop ashing before shifting
the transmission into gear.

If the knob is turned to Four-Wheel High or Two-Wheel
High when your vehicle is in gear and/or moving, the
Four-Wheel High or Two-Wheel high indicator light
will flash for 30 seconds. It will not complete the shift
unless your vehicle is moving less than 3 mph (5 km/h)
with the transmission in NEUTRAL (N).
Shifting Into NEUTRAL
Before shifting the transfer case to NEUTRAL, first
make sure the vehicle is parked so that it will not roll.
1. Set the parking brake.
2. Start the vehicle.
3. Put the transmission in NEUTRAL (N).
4. Shift the transfer case to Two-Wheel High.
5. Turn the transfer case knob all of the way past
Four-Wheel Low and hold it there for a minimum
of 10 seconds. The neutral indicator light will
come on.
6. Shift the transmission to REVERSE (R) for
one second, then shift the transmission to
DRIVE (D) for one second.
7. Turn the ignition to OFF.
8. Place the transmission shift lever in PARK. (P).
9. Turn the ignition to LOCK.
Shifting Out of NEUTRAL
To shift the transfer case out of NEUTRAL, do the
following:
1. Set the parking brake and apply the regular brake
pedal.
2. Turn the ignition to RUN with the engine off.
3. Put the transmission in NEUTRAL (N).
4. Turn the transfer case knob to the desired shift
position (Two-Wheel High, Four-Wheel High,
Four-Wheel Low).
5. After the transfer case has shifted out of NEUTRAL,
the indicator light will go out.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
6. Release the parking brake.
7. Start the engine and shift the transmission lever to
the desired position.
Excessively shifting the transfer case into or out of the
different modes may cause the transfer case to enter the
shift protection mode. This will protect the transfer case
from possible damage and will only allow the transfer
case to respond to one shift per 10 seconds. The transfer
case may stay in this mode for up to three minutes.

move very quickly. You or others could be
injured. To be sure your vehicle will not move,
even when you are on level ground, follow the
steps below.
Two-Speed Rear Axle
1. With the engine running, shift the two-speed rear
axle into low. To be sure it is in low, you will need
to move the vehicle in gear just a little.
2. Hold the regular brake pedal down with your
right foot.
3. Apply the parking brake.
4. Shift the transmission to NEUTRAL for manual
transmission or PARK (P) for automatic
transmission.
Hydraulic Brakes
(Parking Brake Operation)
If your vehicle has hydraulic brakes, it has either a
parking brake foot pedal or hand lever. If you have the
parking brake foot pedal, it is located below the
instrument panel to the left of the steering column.
If you have the parking brake hand lever, it is located to
the right of the driver, on the floor.Parking Brake Hand Lever Shown
