Downshifting
Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. For acceleration at speeds less than 20 mph (30
km/h), 2nd gear is recommended.
CAUTION!
When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the
engine which can cause valve damage.
FOUR-WHEEL- DRIVE OPERATION — IF
EQUIPPED
•
Four-Wheel-Drive Dodge Ram Trucks are equipped
with either a Manually Shifted transfer case or an
Electronically Shifted transfer case. See the operating
instructions for your transfer case, located within this
section.

Manually Shifted Transfer Case Operating
Information/Precautions
The transfer case provides 4 mode positions-2(rear)-
wheel-drive high range, 4-wheel-drive high range, neu-
tral, and 4-wheel-drive low range.
This transfer case is intended to be driven in the 2-wheel-
drive position (2H) for normal street and highway con-
ditions such as dry hard surfaced roads.
When additional traction is required the transfer case 4H
and 4L 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
simply moving the shift lever to the desired positions.
The 4H and 4L positions are intended for loose, slippery
road surfaces only. Driving in the 4H and 4L positions on
dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.The 4-wheel-drive light (4WD), located in the instrument
cluster, alerts the driver that the vehicle is in 4-wheel
drive and that the front and rear driveshafts are locked
together. This light illuminates when the transfer case is
shifted to either the 4H or 4L positions. There is no light
for the 2H or N (Neutral) positions.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H 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 will adversely affect shifting and can
cause damage to the transfer case.
242 STARTING AND OPERATING

NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshaft speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning 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.
NOTE:Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or uneven tire
pressures, excessive vehicle loading, or cold tempera-
tures.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.
For additional information on the appropriate use of each
transfer case mode position see the information below:
2H
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.
STARTING AND OPERATING 243

4H
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.
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.
4L
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).
Shifting Procedure - Manually Shifted Transfer
Case
2H⇔4H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. If the vehicle is in motion,
shifts can be made up to 55 mph (88 km/h). With the
244 STARTING AND OPERATING

vehicle in motion, the transfer case will engage / disen-
gage faster if you momentarily release the accelerator
pedal after completing the shift. Apply a constant force
when shifting the transfer case lever.
2H or 4H⇔4L
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission to N (Neutral) or depress the
clutch on a manual transmission. While the vehicle is
coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case N (Neutral).
NOTE:Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift automatic
transmission to N (Neutral), hold foot on brake, and turn
engine OFF. Make shift to the desired mode.NOTE:Shifting into or out of 4L is possible with the
vehicle completely stopped, however difficulty may oc-
cur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The pre-
ferred method is with the vehicle rolling 2 to 3 mph (3 to
5 km/h). Avoid attempting to engage or disengage 4L
with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h).
NOTE:Do not attempt to shift to or from 4L while the
transmission is in gear or clutch is engaged.
Transfer Case Reminder Light
The four-wheel-drive operating light (4WD), located in
the instrument cluster, is used to alert the driver that the
front axle is fully engaged and all four wheels are
driving.

Electronically Shifted Transfer Case Operating
Information/Precautions
This is an electric shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel.
The Electronically Shifted transfer case provides 4 mode
positions: 2 (rear) wheel drive high range or all 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) or all wheel
drive position (AWD) 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 desiredposition - 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).
Transfer Case Position Indicator Lights —
Electronically Shifted Transfer Case Only
Transfer case position indicator lights are located on the
Four-Wheel-Drive Control Switch, found on your instru-
ment panel, and indicate the current and desired transfer
246 STARTING AND OPERATING

case selection. When you select a different transfer case
position, the indicator lights will do the following:
If All 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 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 casewill 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 theShifting Procedurefor 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 theService 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. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshaft speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.When operating your vehicle in 4LO, the engine speed is
approximately three times that of the 2WD/AWD 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
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.
