Shifting Into Four-Wheel High
Turn the knob to four-wheel high. This can be done at
3 mph or less. The indicator light flashes while shifting.
It remains on after the shift is complete. Be sure to
lock the front hubs.
Shifting Into Two-Wheel High
Turn the knob to Two-Wheel High. This can be done at
3 mph or less.
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 N (Neutral).
The preferred method for shifting into Four-Wheel Low is
to have the 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 on before shifting the transmission into gear.
Be sure to lock the front hubs.Notice:Shifting the transmission into gear before
the Four-Wheel Drive Low indicator light has
stopped flashing could damage the transfer case.
To help avoid damaging the vehicle, always wait for
the Four-Wheel Drive Low indicator light to stop
flashing before shifting the transmission into gear.
If you turn the knob to Four-Wheel Low while the
vehicle is in gear and/or moving, the Four-Wheel Low
indicator light flashes for 30 seconds and does not
complete the shift unless the vehicle is moving less than
3 mph (4.8 km/h) and the transmission is in N (Neutral).
After 30 seconds, the transfer case returns to the
setting last chosen. If the vehicle is in gear and moving
less than 3 mph (4.8 km/h), the transfer case shifts
to Four-Wheel High.

Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High or
Two-Wheel High, the vehicle must be stopped or moving
less than 3 mph (5 km/h) with the transmission in
N (Neutral) with the engine running. The preferred
method for shifting out of Four-Wheel Low is to have
the 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 on before
shifting the transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel High or Two-Wheel High indicator
light has stopped flashing could damage the transfer
case. To help avoid damaging the vehicle, always
wait for the Four-Wheel High or Two-Wheel High
indicator light to stop flashing before shifting
the transmission into gear.
If the knob is turned to Four-Wheel High or Two-Wheel
High while the vehicle is in gear and/or moving, the
Four-Wheel High or Two-Wheel high indicator light
flashes for 30 seconds. It will not complete the shift
unless the vehicle is moving less than 3 mph (5 km/h)
with the transmission in N (Neutral).
Shifting Into Neutral
Before shifting the transfer case to N (Neutral), first
make sure the vehicle is parked so that it will not roll.
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Start the vehicle.
3. Put the transmission in N (Neutral).
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 N (Neutral) indicator light
comes on.

Shifting Out of Neutral
To shift the transfer case out of N (Neutral), do the
following:
1. Set the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Apply the regular brake pedal.
3. Turn the ignition to ON/RUN with the engine off.
4. Put the transmission in N (Neutral).
5. Turn the transfer case knob to the desired shift
position (Two-Wheel High, Four-Wheel High,
Four-Wheel Low).
6. After the transfer case has shifted out of N (Neutral),
the indicator light goes 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.
7. Release the parking brake.
8. Start the engine and shift the transmission lever to
the desired position.Excessively shifting the transfer case into or out of the
different modes can cause the transfer case to enter the
shift protection mode. This protects the transfer case from
possible damage and only allows the transfer case to
respond to one shift per 10 seconds. The transfer case
can stay in this mode for up to three minutes.
Parking
{CAUTION:
If you do not park the vehicle properly, it can roll.
If you have left the engine running, it can move
very quickly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on level ground, follow the steps below.
2-35

Parking a Vehicle With the 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 brake pedal down.
3. Apply the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
4. Shift the transmission to N (Neutral) for manual
transmission or P (Park) for automatic transmission.
Two-Speed Rear Axle
The Two-Speed rear axle lets the driver select Low
Range and High Range. Low Range provides good
starting torque and pulling power. When selecting High
Range the axle allows for higher road speed and
fuel economy.For better performance during off-road or under a heavy
load, shift the axle into Low Range and then operate
the transmission normally.
For better performance on the highway, shift the axle to
High Range and operate the transmission normally.
High or Low Range can be used when additional shifts
between transmission gears is needed while driving
on grades and for better fuel economy.
Notice:Driving in Low Range above 50 mph
(80.5 kph) will damage driveline components. Drive
below 50 mph (80.5 kph) in Low Range.
If the vehicle has this feature, there is a label on the
headliner above the windshield or in another place near
the driver that shows how to use it. Be sure to follow
the directions carefully.

{CAUTION:
It can be dangerous to get out of the vehicle
without the parking brake firmly set. The vehicle
can roll. If you have left the engine running, the
vehicle can move suddenly. You or others could
be injured. To be sure the vehicle will not move,
even when you are on fairly level ground, always
set the parking brake.
To set the hand lever parking brake, hold the regular
brake pedal down, then pull up on the handle, until
it stops.
If the ignition is on when the parking brake is set, the
brake system warning light will come on.Once the parking brake is applied, slowly remove your
foot from the regular brake pedal, while checking to
see if the vehicle moves. If the vehicle does start
to move, press the regular brake pedal and adjust the
parking brake holding force. See “Parking Brake
Adjustment” later in this section.
If the parking brake still does not set, take the vehicle to
your dealer/retailer for service.
To release the foot pedal parking brake, hold the
regular brake pedal down. Pull the brake release handle,
located just above the parking brake pedal.
To release the hand lever parking brake, hold the
regular brake pedal down and push down on the handle
until it stops.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.

Engine Exhaust
{CAUTION:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to CO
can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
•The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airflow or tail pipes).
•The exhaust smells or sounds strange or
different.
•The exhaust system leaks due to corrosion or
damage.
CAUTION: (Continued)
CAUTION: (Continued)
•
The vehicle’s exhaust system has been
modified, damaged or improperly repaired.
•There are holes or openings in the vehicle
body from damage or after-market
modifications that are not completely sealed.
If unusual fumes are detected or if it is suspected
that exhaust is coming into the vehicle:
•Drive it only with the windows
completely down.
•Have the vehicle repaired immediately.
Never park the vehicle with the engine running in
an enclosed area such as a garage or a building
that has no fresh air ventilation.

Diesel Particulate Filter
The vehicle has a Diesel Particulate Filter (DPF) as part
of the exhaust system to reduce vehicle emissions. The
DPF requires a unique exhaust tailpipe with an exhaust
cooler. The exhaust cooler mixes air with the exhaust to
lower the temperature before it leaves the tailpipe.
The DPF, the tailpipe, or other exhaust system
components must not be altered. Inspect regularly and
clean any mud or dirt from the exhaust cooler,
especially where the exhaust cooler connects to the
tailpipe and the openings where fresh air enters
the cooler. See “Exhaust System Inspection” underAt
Least Twice a Year on page 6-27.
The DPF will clean itself as part of normal operation.
Several factors including fuel consumed, hours of engine
operation and miles driven are monitored by the Engine
Control Module (ECM). The self cleaning occurs
approximately once per tank of fuel.
During self cleaning, the
green DPF indicator light
will come on. See
Diesel Particulate Filter
Warning Light on
page 3-46.To clean the filter, either drive the vehicle above 30 mph
(50 km/h) to activate self cleaning, or stop the vehicle
and perform the manual cleaning procedure. For
self cleaning, drive until the green DPF indicator light
goes off. This will take approximately 20 minutes. Once
self cleaning has started, drive until the green indicator
light goes off to complete the cleaning in a single
operation if possible.
Extended idling can cause exhaust parts and gases to
become very hot. Keep the exhaust area clear of
material that could ignite or burn. SeeParking Over
Things That Burn on page 2-44for more information.
{CAUTION:
During DPF self cleaning or during extended idling
in P (Park), the exhaust system and exhaust
gases are very hot. Things that burn could touch
hot exhaust parts under the vehicle and ignite.
You or others could be burned. Do not park, or
idle for an extended period of time, near or over
papers, leaves, dry grass, or other things that can
burn. Keep the exhaust area clear of material that
could ignite or burn. SeeParking Over Things
That Burn on page 2-44for more information.
2-46

Notice:Extended idle should be avoided because
the DPF system is not capable of self cleaning at
idle. During extended idle operation, monitor the
instrument panel telltale lights and Driver Information
Center for messages and take appropriate indicated
action. Continued idling with the warning light/
message on could cause irreversible damage to the
DPF requiring repair and possible replacement that
might not be covered by the vehicle warranty.
When the yellow DPF indicator comes on, the filter is
dirty and needs cleaning. You will also notice a change
in the exhaust sound and engine idle speed. This is
normal. If you continue to drive and the exhaust filter is
not cleaned as required, the DPF indicator will change
from yellow to red. Continuing to drive the vehicle
with the red indicator can cause filter damage.
Vehicles with DPF have specific fuel and engine oil
requirements. SeeWhat Fuel to Use on page 5-8and
Engine Oil (DURAMAX Diesel Engine) on page 5-24
orEngine Oil (Caterpillar Diesel Engine) on page 5-27or
Engine Oil (Isuzu Diesel Engine) on page 5-28or
Engine Oil (Gasoline Engine) on page 5-32for more
information on those requirements.Notice:Permanent damage can occur to the DPF
or related components if the required Ultra Low
Sulfur Diesel (15 ppm sulfur maximum) or low ash
CJ-4 engine oil is not used. This damage would
not be covered by the vehicle warranty.
For vehicles with Power Take-Off (PTO), monitor the
instrument panel cluster for lights related to the DPF.
All engines consume some amount of engine oil. Ash
is the by-product of engine oil consumption. The ash will
become trapped in the DPF over the life of the vehicle.
Eventually, the buildup of ash will restrict the exhaust
gases and the DPF will need to be cleaned or replaced.
SeeAccessories and Modifications on page 5-3for
important information if you are considering adding
accessories or modifying the vehicle.
