2013 Ram 1500 Owner's Manual

This electronically shifted transfer case provides four
mode positions:
•Two-wheel drive high range (2WD)
• Four-wheel drive lock range (4WD LOCK)
• Four-wheel drive low range (4WD LOW)
• Neutral (NEUTRAL)
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.
When additional traction is required, the transfer case 4WD
LOCK and 4WD LOW positions can be used to lock the
front and rear driveshafts together, forcing the front and
rear wheels to rotate at the same speed. This is accom-
plished by rotating the 4WD Control Switch to the desired
position. Refer to “Shifting Procedure” in this section for
specific shifting instructions. The 4WD LOCK and 4WD LOW positions are designed for loose, slippery road sur-
faces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard surfaced roads may cause increased
tire wear and damage to the driveline components.
NOTE:
The transfer case NEUTRAL position is selected
by pressing the recessed button located on the lower left
hand corner of the 4WD Control Switch. The transfer case
NEUTRAL position is to be used for recreational towing
only. Refer to “Recreational Towing” in “Starting and
Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) 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:
5
STARTING AND OPERATING 391

If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until thetransfer 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 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
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic
shift 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 function-
ing properly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may

WARNING!(Continued)
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 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD LOCK 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. 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.
WARNING!
You or others could be injured or killed 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 transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.

STARTING AND OPERATING 393

For additional information on the appropriate use of each
transfer case mode position, see the information below:
2WD
Rear Wheel Drive High Range - This range is for normal
street and highway driving on dry, hard surfaced roads.
4WD LOCK
Four-Wheel Drive Lock Range - This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. This range 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 locks the front and rear
driveshafts together forcing the 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).
N
Neutral - This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in “Starting and Operating” for further infor-
mation.
394 STARTING AND OPERATING

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 indicator light for the previous
position will remain ON and the newly selected posi-
tion indicator light will continue to flash until all the
requirements for the selected position have been met.
To retry a shift: return the control knob back to the
original position, make certain all shift requirements
have been met, wait five seconds and try the shift
again.
• If all the requirements to select a new transfer case
position have been met, the current position 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 LOCK
Rotate the 4WD control switch to the desired position.
Shifts between 2WD and 4WD LOCK 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 turn-
ing the control switch. If the vehicle is stopped, the
ignition switch must be in the ON position with the
engine either running or off. This shift cannot be com-
pleted if the ignition switch is in the ACC position.
NOTE: The four-wheel drive system will not allow shifts
between 2WD/4WD LOCK if the front and/or rear
wheels are spinning (no traction). In this situation, the
selected position indicator light will flash and the origi-
nal position indicator light will remain ON. At this time,
5
STARTING AND OPERATING 395

reduce speed and stop spinning the wheels to complete
the shift.
2WD Or 4WD LOCK 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, rotate the transfer case control switch to the desired position. 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 position and the engine either OFF or running, shift the transmission
into NEUTRAL.
3. Rotate the transfer case control switch to the desired position.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
396 STARTING AND OPERATING

NOTE:
•If Steps 1 or 2 of either the Preferred or Alternate
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 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
position, the shift will not take place and no position
indicator lights will be on or flashing.
Electronically Shifted Transfer Case
(Five-Position Switch) – If Equipped
This is an electronic shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel. 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)
Transfer Case Switch (Five–Position)
5
STARTING AND OPERATING 397

•Four-wheel drive low range (4WD LOW)
• Neutral (NEUTRAL)
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.
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 LOCK and 4WD LOW positions can be used to lock
the front and rear driveshafts together forcing the front and rear wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control Switch to the
desired position. Refer to “Shifting Procedure” for spe-
cific shifting instructions. The 4WD LOCK and 4WD
LOW positions are designed for loose, slippery road
surfaces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
NOTE:
The transfer case NEUTRAL position is selected
by depressing the recessed button located on the lower
left hand corner of the 4WD Control Switch. The transfer
case NEUTRAL position is to be used for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.
