2006 DODGE RAM 1500 GAS wheel

This Electronically Shifted transfer case provides 5 mode
positions: 2 wheel drive (2WD), 4WD AUTO, 4WD HI,
Neutral and 4WD Lo.
The Electronically Shifted transfer case is designed to be
driven in the 2 wheel drive position (2WD) or 4 wheel
drive position (4WD AUTO) for normal street and high-
way conditions (dry hard surfaced roads). Driving the
vehicle in 2WD will have greater fuel economy benefits,
as the front axle is not engaged in 2WD.
For variable driving conditions the 4WD AUTO mode
can be used. In this mode the front axle is engaged, but
the vehicle’s power is sent to the rear wheels. Four wheel
drive will be automatically engaged when the vehicle
senses a loss of traction. Because the front axle is en-
gaged, this mode will result in lower fuel economy than
the 2WD mode. When additional traction is required, the transfer case
4WD HI and 4WD LO positions can be used to lock the
front and rear driveshafts together and force the front
and rear wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control Switch to the
desired position - see Shifting Procedure section for
specific shifting instructions. The 4WD HI and 4WD LO
positions are designed for loose, slippery road surfaces
only. Driving in the 4WD HI and 4WD LO positions on
dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.

If One or More Shift Conditions are not Met
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will con-
tinue to flash.
3. The transfer case will notshift.
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, turn
the control knob back to the current position, wait five (5)
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section of the owner’s manual.
The “SERVICE 4WD” warning light monitors the electric
shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the
4WD system is not functioning properly and that service
is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the
Service 4WDlight is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
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 LO, the engine
speed is approximately three times that of the 2WD, 4WD

AUTO or 4WD HI 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 4 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
transfer case.
Because 4 wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
316 STARTING AND OPERATING

For additional information on the appropriate use of each
transfer case mode position see the information below:
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
4WD AUTO
Automatic 4–wheel drive sends power to the rear wheels.
4–wheel drive will be automatically engaged when the
vehicle senses a loss of traction. Additional traction for
varying road conditions.
4WD HI
4 Wheel Drive High Range - Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. Additional traction for loose,
slippery road surfaces only. 4WD LO
4 Wheel Drive Low Range - Low speed 4 wheel drive.
Locks the front and rear driveshafts together. Forces the
front and rear wheels to rotate at the same speed.
Additional traction and maximum pulling power for
loose, slippery road surfaces only. Do not exceed 25 mph
(40 km/h).
N
Neutral - Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. See Recreational Towing for more infor-
mation.

This Electronically Shifted transfer case provides 4 mode
positions: 2 (rear) wheel drive high range, 4 wheel drive
high range, 4 wheel drive low range, and neutral.
The Electronically Shifted transfer case is designed to be
driven in the 2 wheel drive position (2WD) for normal
street and highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4HI and 4LO positions can be used to lock the front and
rear driveshafts together and force the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the 4WD Control Switch to the desired
position - see Shifting Procedure section for specific
shifting instructions. The 4HI and 4LO positions are
designed for loose, slippery road surfaces only. Driving
in the 4HI and 4LO positions on dry hard surfaced roads
may cause increased tire wear and damage to the driv-
eline components. NOTE:
The transfer case Neutral (N) position is selected
by depressing the recessed button located on the lower
left hand corner of the 4WD Control Switch. The transfer
case Neutral (N) position is to be used for recreational
towing only. See the Recreational Towing section for
specific procedures on shifting into and out of Neutral
(N).

WARNING!
Always engage the parking brake when powering
down the vehicle if the Service 4WDlight is illumi-
nated. Not engaging the parking brake may allow the
vehicle to roll which may cause personal injury.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning, as this can cause
damage to driveline components.
When operating your vehicle in 4LO, the engine speed is
approximately three times that of the 2WD or 4HI
positions at a given road speed. Take care not to over-
speed the engine and do not exceed 25 mph (40 km/h).
Proper operation of 4 wheel drive vehicles depends on

disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move

key must be in the ON position with the engine either
RUNNING or OFF. This shift cannot be completed if the
key is in the accessory position.
NOTE: The 4x4 system will not allow shifts between
2WD/4HI if the front and/or rear wheels are spinning
(no traction). In this situation the selected position indi-
cator 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 4HI ⇔4LO
NOTE: When shifting into or out of 4LO 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. USE EITHER
OF THE FOLLOWING PROCEDURES:
Preferred Procedure 1. With engine RUNNING, slow vehicle to 2 to 3 mph (3
to 5 km/h).
2. Shift the transmission into NEUTRAL (depress clutch
on manual transmissions).
3. While still rolling, rotate the transfer case control
switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or
RUNNING, shift the transmission into NEUTRAL (de-
press clutch on manual transmissions).
3. Rotate the transfer case control switch to the desired
position.
