FIVE-POSITION/ON-DEMAND TRANSFER CASE
•
This electronically shifted transfer case
provides five mode positions:
• Two-wheel drive high range (2WD)
• Four-wheel drive automatic range
(4WD AUTO)
• Four-wheel drive lock range (4WD LOCK)
• Four-wheel drive low range (4WD LOW)
• NEUTRAL (N)
•
This electronically shifted transfer case
is designed to be driven in the two-wheel
drive position (2WD) or four-wheel drive
position (4WD AUTO) for normal street
and highway conditions on dry, hard-
surfaced roads.
• Driving the vehicle in 2WD will have greater fuel economy benefits as the front axle is not engaged in 2WD.
Shifting Procedure
• Shifting between 2WD and 4WD AUTO or 4WD LOCK can be made with the vehicle stopped or in motion at speeds up to 55 mph (88 km/h).
• Shifting between 2WD, 4WD AUTO and 4WD LOCK into 4WD LOW must be made with the transmission in NEUTRAL and the vehicle stopped or rolling at 2 to 3 mph
(3 to 5 km/h).
NOTE:
It is preferred to have the engine running and the vehicle moving at 2 to 3 mph
(3 to 5 km/h).
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer
case in the NEUTRAL position without first fully engaging the parking brake. The
transfer case NEUTRAL position disengages both the front and rear driveshafts
from the powertrain and will allow the vehicle to move regardless of the transmis-
sion position. The parking brake should always be applied when the driver is not
in the vehicle.

TOW/HAUL MODE
•When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent
transmission shifting occurs, press the TOW/HAUL switch to select TOW/HAUL
mode. This will improve performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When operating in TOW/HAUL mode,
transmission upshifts are delayed, and the transmission will automatically downshift
(for engine braking) during steady braking maneuvers.
• The “TOW/HAUL Indicator Light” will illuminate in the instrument cluster to
indicate that TOW/HAUL mode has
been activated. Pressing the switch a
second time restores normal operation.
If the TOW/HAUL mode is desired, the
switch must be pressed each time the
engine is started.
INTEGRATED TRAILER BRAKE MODULE
• The Integrated Trailer Brake Controller allows you to automatically or manuallyactivate the Electric Trailer Brakes and Electric Over Hydraulic Trailer Brakes for a
better braking performance when towing a trailer.
NOTE:
The Integrated Trailer Brake Controller is located in the center stack below the
climate controls.
• This module will have four different options depending on the type of trailer you want to tow and can be selected through the Electronic Vehicle Information Center
(EVIC) or touch-screen radio – if equipped.• Light Electric
• Heavy Electric
• Light EOH (Electric Over Hydraulic)
• Heavy EOH (Electric Over Hydraulic)

Cold Start Procedure
• Turn the ignition switch to the ON position. If the Wait To Start
light appears
in the cluster, wait for the light to turn off before starting.
• In extremely cold weather below 0°F (-18°C) it may be beneficial to cycle the manifold heaters twice before attempting to start the engine. This can be
accomplished by turning the ignition OFF for at least five seconds and then back
ON after the “Wait To Start Light” has turned off, but before the engine is started.
However, excessive cycling of the manifold heaters will result in damage to the
heater elements or reduced battery voltage.
• Refer to the Owner's Manual Diesel Supplement on the DVD for further details.
Engine Idling
• Avoid prolonged engine idling. Long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel
may not burn completely.
• Incomplete combustion allows carbon and varnish to form on piston rings, engine valves, and injector nozzles. Also, the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the engine.
• If the engine is allowed to idle, under some conditions the idle speed may increase to 900 RPM then return to normal idle speed. This is normal operation.
WARNING!
Remember to disconnect the cord before driving. Damage to the 110–115 volt
electrical cord could cause electrocution.
DIESEL EXHAUST BRAKE (ENGINE BRAKING)
• The exhaust brake feature will only function when the driver presses the exhaustbrake switch.
• The switch is located on the switch bank below the audio system.
• Your vehicle is also equipped with the Smart Brake feature.
• This feature will automatically provide a variable amount of engine braking in an attempt to maintain a constant vehicle speed.
• The Smart Brake is activated by pressing the exhaust brake switch twice. The first press activate the full strength brake, second press activates the Smart Brake and
third press turns the brake off.
• The Smart Brake target vehicle speed is set when either the vehicle brake or the throttle pedal is released.
• Exhaust braking is most effective when the engine RPM is higher.
NOTE:
For optimum braking power, it is recommended to use the exhaust brake while in
TOW/HAUL mode.

Hub Caps/Wheel Covers
• The hub caps must be removed before raising the vehicle off the ground.
• For single rear-wheel (SRW) models, use the blade on the end of the lug wrenchto pry the hub cap off. Insert the blade end into the pry-off notch and carefully pop
off the hub cap with a back-and-forth motion.
• On models with dual rear wheels (DRW), you must first remove the hub caps. The jack handle driver has a hook at one end that will fit in the pry off notch of the rear
hub caps. Position the hook and pull out on the ratchet firmly. The hub cap should
pop off. The wheel skins can now be removed. For the front hub cap use the blade
on the end of the lug wrench to pry the caps off. The wheel skin can now be
removed.
• You must use the flat end of the lug wrench to pry off the wheel skins. Insert the flat tip completely and using a back-and-forth motion, loosen the wheel skin.
Repeat this procedure around the tire until the skin pops off.
• Replace the wheel skins first using a rubber mallet. When replacing the hub caps, tilt the cap retainer over the lug nut bolt circle and strike the high side down with
a rubber mallet. Be sure that the hub caps and wheel skins are firmly seated
around the wheel.
Wheel Nuts
• All wheel nuts should be tightened occasionally to eliminate the possibility of wheel studs being sheared or the bolt holes in the wheels becoming elongated.
This is especially important during the first few hundred miles/kilometers of
operation to allow the wheel nuts to become properly set. All wheel nuts should
first be firmly seated against the wheel. The wheel nuts should then be tightened
to recommended torque. Tighten the wheel nuts to final torque in increments.
Progress around the bolt circle, tightening the wheel nut opposite to the wheel nut
just previously tightened until final torque is achieved. Recommended torques are
shown in the following chart.

8-Stud — Dual Rear Wheels
• Dual wheels are flat-mounted and center-piloted. The lug nuts are a two-pieceassembly. When the tires are being rotated or replaced, clean these lug nuts and
add two drops of oil at the interface between the hex and the washer.
• Slots in the wheels will assist in prop- erly orienting the inner and outer
wheels. Align these slots when assem-
bling the wheels for best access to the
tire valve on the inner wheel. The tires
of both dual wheels must be com-
pletely off the ground when tightening,
to ensure wheel centering and maxi-
mum wheel clamping.
• Dual wheel models require a special heavy-duty lug nut tightening adapter
(included with the vehicle) to correctly
tighten the lug nuts. Also, when it is necessary to remove and install dual rear
wheels, use a proper vehicle lifting device.
NOTE:
When installing a spare tire as part of a dual rear wheel end combination, the tire
diameter of the two individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front location. The correct direction
of rotation for dual tire installations must also be observed.
These dual rear wheels should be tightened as follows:
1.
Tighten the wheel nuts in the numbered
sequence to a snug fit.
2.Retighten the wheel nuts in the same
sequence to the torques listed in the
table. Go through the sequence a sec-
ond time to verify that specific torque
has been achieved. Retighten to speci-
fications at 100 miles (160 km) and
after 500 miles (800 km).
•It is recommended that wheel stud nuts
be kept torqued to specifications at all
times. Torque wheel stud nuts to specifications at each lubrication interval.

FREEING A STUCK VEHICLE
• If your vehicle becomes stuck in mud, sand or snow, it can often be moved by arocking motion. Turn your steering wheel right and left to clear the area around the
front wheels. Then, move the shift lever back and forth between REVERSE and
DRIVE. Using minimal accelerator pedal pressure to maintain the rocking motion,
without spinning the wheels, is most effective.
• Allow the engine to idle with the transmission shift lever in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during prolonged efforts to free a stuck
vehicle.
NOTE:
If your vehicle is equipped with Electronic Stability Control (ESC) then press the
"ESC Off" switch, to place the Electronic Stability Control (ESC) system in "Partial
Off" mode, before rocking the vehicle.
CAUTION!
Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels above
30 mph (48 km/h) while in gear (no transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause tire damage or failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph (48 km/h) when you are stuck. Do
not let anyone near a spinning wheel, no matter what the speed.
