CAUTION! (Continued)• Do not disconnect the rear driveshaft because fluid
will leak from the transfer case, causing damage to
internal parts.
• Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
WARNING!You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging (Continued) WARNING! (Continued)the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive
shaft from the powertrain, and will allow the vehicle
to roll, even if the automatic transmission is in PARK
(or manual transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop, with the engine
running. Firmly apply the parking brake. 5STARTING AND OPERATING 531

tow bar.
14. Release the parking brake.
NOTE: With electronic shift transfer case:
• Steps 2 through 5 are requirements that must be met
before pushing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met before push-
ing the NEUTRAL (N) button or are no longer met
during the shift, the NEUTRAL (N) indicator light will
flash continuously until all requirements are met or
until the NEUTRAL (N) button is released.
• The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing. • A flashing NEUTRAL (N) position indicator light
indicates that shift requirements have not been met.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Turn the ignition switch to the ON/RUN position, but
do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
• With manual shift transfer case, shift the transfer
case lever to the desired position. 5STARTING AND OPERATING 533

• With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button until the NEU-
TRAL (N) indicator light turns off. After the NEU-
TRAL (N) indicator light turns off, release the NEU-
TRAL (N) button. After the NEUTRAL (N) button
has been released, the transfer case will shift to the
position indicated by the selector switch.
NOTE: When shifting the transfer case out of NEUTRAL
(N), the engine should remain OFF to avoid gear clash.
6. Shift automatic transmission into PARK.
7. Release the brake pedal (and clutch pedal on a manual
transmission).
8. Disconnect vehicle from the tow vehicle.
9. Start the engine.
10. Press and hold the brake pedal.
11. Release the parking brake. 12. Shift the transmission into gear, release the brake
pedal (and clutch pedal on manual transmissions),
and check that the vehicle operates normally.
NOTE: With electronic shift transfer case:
• Steps 3 through 5 are requirements that must be met
before pressing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met before push-
ing the NEUTRAL (N) button or are no longer met
during the shift, the NEUTRAL (N) indicator light will
flash continuously until all requirements are met or
until the NEUTRAL (N) button is released.
• The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.

Jacking Instructions
Instructions
WARNING!Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
• Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE. (Continued) WARNING! (Continued)• Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.542 WHAT TO DO IN EMERGENCIES

When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Securely place the jack under the sway
bar bracket (unless both tires are flat on one side, then
place jack under shock bracket) facing forward in vehicle.
Connect the jack tube extension and lug wrench. Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE: If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the
jack drive tube in order to lower the jack.
4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!Raising the vehicle higher than necessary can make
the vehicle unstable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped
end of the nuts toward the wheel on single rear wheelRear Jacking Location544 WHAT TO DO IN EMERGENCIES

(SRW) models. On dual rear wheel models (DRW) the
lug nuts are a two-piece assembly with a flat face.
Lightly tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the nuts until
the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. For the proper lug nut
torque specifications refer to “Wheel and Tire Torque
Specifications” in this section. If in doubt about the
correct tightness, have them checked with a torque
wrench by your authorized dealer or at a service
station.
WARNING!A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided. 7. Install wheel center cap (if equipped) and remove
wheel blocks. Do not install chrome or aluminum
wheel center caps on the spare wheel. This may result
in cap damage.
8. Lower the jack to its fully closed position. If the jack
will not lower by turning the dial (thumbwheel) by
hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack,
and tools as previously described.
9. Adjust the tire pressure when possible.
Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising the vehicle
off the ground. 6WHAT TO DO IN EMERGENCIES 545

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.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builders Guide for information
on stowing your spare tire (if equipped). HOISTING
A conventional floor jack may be used at the jacking
locations. Refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts of the underbody.
CAUTION!Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.548 WHAT TO DO IN EMERGENCIES
