140STARTING AND OPERATING
FOUR-WHEEL DRIVE OPERATION —
IF EQUIPPED
Four-wheel drive trucks are equipped with either a
manually shifted transfer case or an electronically
shifted transfer case.
ELECTRONICALLY SHIFTED TRANSFER
C
ASE (8-SPEED TRANSMISSION) — IF
E
QUIPPED
This is an electronically shifted transfer case and is
operated by the 4WD Control Switch (Transfer
Case Switch), which is located on the instrument
panel.
Four-Position Transfer Case
This electronically shifted transfer case provides
four positions:
Two-Wheel Drive High Range (2WD)
Four-Wheel Drive High Range (4WD HIGH)
Four-Wheel Drive Low Range (4WD LOW)
N (Neutral)
For additional information on the appropriate use
of each transfer case position, see the information
below:
2WD
Two-Wheel Drive High Range — This range is for
normal street and highway driving on dry, hard
surfaced roads.
4WD HIGH
Four-Wheel Drive High Range — This range provides
torque to the front driveshaft (engages four-wheel
drive) which allows front and rear wheels to spin at
the same speed. This provides additional traction for
loose, slippery road surfaces only.
4WD LOW
Four-Wheel Drive Low Range — This range provides
low speed four-wheel drive. It maximizes torque
(increased torque over 4WD High) to the front
wheels, allowing front 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 this range. N (Neutral)
N (Neutral) — This range disengages both the front
and rear driveshafts from the powertrain. To be
used for flat towing behind another vehicle
Ú
page 194.WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first
fully engaging the parking brake. The transfer
case N (Neutral) position disengages both the
front and rear drive shaft from the powertrain,
and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake
should always be applied when the driver is
not in the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
23_DPF_OM_EN_USC_t.book Page 140
Page 143 of 444

STARTING AND OPERATING141
This electronically shifted transfer case is designed
to be driven in the two-wheel drive position (2WD)
for normal street and highway conditions on dry
hard surfaced roads. Driving the vehicle in
two-wheel drive will have greater fuel economy
benefits as the front axle is not engaged in
two-wheel drive.
When additional traction is required, the transfer
case 4WD HIGH and 4WD LOW positions can be
used to maximize torque to the front driveshaft,
forcing the front and rear wheels to rotate at the
same speed. This is accomplished by pushing the
desired position on the four-wheel drive control
switch.
For specific shifting instructions Ú page 144.
The 4WD HIGH and 4WD LOW positions are
designed for loose, slippery road surfaces only.
Driving in the 4WD HIGH and 4WD LOW positions
on dry, hard surfaced roads may cause increased
tire wear and damage to the driveline components.
NOTE:The transfer case N (Neutral) button is located in
the center of the four-wheel drive Control Switch
and is pushed by using a ballpoint pen or similar
object. The transfer case N (Neutral) position is to
be used for recreational towing only Ú page 194.Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
and 4WD LOW) are located in the instrument
cluster and indicate the current and desired
transfer case selection. When you select a
different transfer case position, the indicator lights
will do the following:
If All Of The Following Shift Conditions Are Met:
1. The current position indicator light will turn off.
2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on.
If One Or More Of The Following Shift Conditions
Are Not Met:
1. The indicator light for the current position will remain on.
2. The newly selected position indicator light will continue to flash.
3. The transfer case will not shift.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry the selection, push the current position, wait five
seconds, and retry selection Ú
page 144.
The SERV 4WD Warning Light monitors the
electronically shifted four-wheel drive system. If
this light remains on after engine start-up or
illuminates during driving, it means that the
four-wheel drive system is not functioning properly
and that service is required.
NOTE:Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the two-wheel drive or 4WD HIGH positions at a
given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the drivetrain.
WARNING!
Always engage the parking brake when powering
down the vehicle if the SERV 4WD Warning Light
is illuminated. Not engaging the parking brake
may allow the vehicle to roll which may cause
personal injury or death.4
23_DPF_OM_EN_USC_t.book Page 141
Page 144 of 444

142STARTING AND OPERATING
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
Shifting Procedure
NOTE:
If any of the requirements to select a new
transfer case position have not been met, the
transfer case will not shift. The position indi -
cator light for the previous position will remain
on and the newly selected position indicator
light will continue to flash until all the require -
ments for the selected position have been met.
If all the requirements to select a new transfer
case position have been met, the current posi -
tion indicator light will turn off, the selected
position indicator light will flash until the
transfer case completes the shift. When the
shift is complete, the position indicator light for
the selected position will stop flashing and
remain on.
2WD TO 4WD HIGH
Push the desired position on the four-wheel drive
control switch to shift the transfer case. Shifts
between two-wheel drive and 4WD HIGH can be
done with the vehicle stopped or in motion. With
the vehicle in motion, the transfer case will
engage/disengage faster if you momentarily
release the accelerator pedal after turning the control switch. If the vehicle is stopped, the ignition
switch must be in the ON/RUN position with the
engine either running or off. This shift cannot be
completed if the ignition switch is in the ACC
position.
NOTE:The four-wheel drive system will not allow shifts
between 2WD/4WD HIGH if the front and/or rear
wheels are spinning (no traction). In this situation,
the selected position indicator light will flash and
the original position indicator light will remain on.
At this time, reduce speed and stop spinning the
wheels to complete the shift.
2WD OR 4WD HIGH TO 4WD LOW
NOTE:
When shifting into or out of 4WD LOW some gear
noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2
to 3 mph (3 to 5 km/h) or completely stopped. You
can use either of the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to 2
to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, push the desired position on the transfer case control switch. 4. After the desired position indicator light is on
(not flashing), shift the transmission back into
gear.
Alternate Procedure
1. Bring the vehicle to a complete stop.
2. With the ignition switch in the ON/RUN position and the engine running, shift the
transmission into NEUTRAL.
3. Push the desired position on the transfer case control switch.
4. After the desired position indicator light is on (not flashing), shift the transmission back into
gear.NOTE:
If Steps 1 or 2 of either the Preferred or Alter -
nate Procedure are not satisfied prior to
attempting the shift, then the desired position
indicator light will flash continuously while the
original position indicator light is on, until all
requirements have been met.
The ignition switch must be in the ON/RUN posi -
tion 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.
