2017 Ram 3500 Transfer case

3. Push the desired position on the transfer case controlswitch.
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 Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift attempt
is in process, 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, then the shift will not take place and no
position indicator lights will be on or flashing.
Five-Position Electronically Shifted Transfer Case
(Eight Speed Transmission Only) — 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 High Range (4WD AUTO)
• Four-Wheel Drive Lock High Range (4WD LOCK)
• Four-Wheel Drive Low Range (4WD LOW)
• Neutral (NEUTRAL)

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 AUTO
Four-Wheel Drive Auto High Range — This range sends
power to the front wheels. The four–wheel drive system
will be automatically engaged when the vehicle senses a
loss of traction. Additional traction for varying road con-
ditions.
4WD LOCK
Four-Wheel Drive Lock High Range — This range maxi-
mizes torque to the front driveshaft, forcing the front and
rear wheels to rotate at the same speed. 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 to the front
driveshaft, forcing the front and rear wheels to rotate at thesame speed. This range provides additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
NEUTRAL (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 information.
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 engaged, this
mode will result in lower fuel economy than the 2WD
mode.

STARTING AND OPERATING 433

When additional traction is required, the transfer case 4WD
LOCK 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
pushing the desired position on the 4WD Control Switch.
Refer to “Shifting Procedure” in this section for specific
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 increased tire wear and damage to the
driveline components.
NOTE:The transfer case NEUTRAL button is located in
the center of the 4WD Control Switch and is pushed by
using a ballpoint pen or similar object. 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, 4LOW,
and 4WD AUTO) 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 notshift.
434 STARTING AND OPERATING

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. To
find the shift requirements, 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 functioning 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
allow the vehicle to roll which may cause personal
injury or death.
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 2WD, 4WD
AUTO 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 (N) position without first fully engaging
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

WARNING!(Continued)
brake should always be applied when the driver is
not in the vehicle.
• The transmission may not engage PARK if the ve-
hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, before exiting the vehicle.
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 posi-
tion 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 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 AUTO Or 4WD LOCK
Push the desired position on the 4WD Control Switch to
shift the transfer case. Shifts between 2WD and 4WD
AUTO 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 momen-
tarily release the accelerator pedal after selecting the de-
sired position on 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
completed if the ignition switch is in the ACC position.
NOTE: The four-wheel drive system will not allow shifts
between 2WD and 4WD AUTO/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 original position indicator light will remain ON. At this
time, reduce speed and stop spinning the wheels to com-
plete the shift.
436 STARTING AND OPERATING

2WD Or 4WD AUTO 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. 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 complete stop.
2. With the ignition switch in the ON 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 Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift attempt
is in process, 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, then the shift will not take place and no
position indicator lights will be on or flashing.

STARTING AND OPERATING 437

NOTE:The stabilizer/sway bar may be torque locked due
to left and right suspension height differences. This condi-
tion is due to driving surface differences or vehicle loading.
In order for the stabilizer/sway bar to disconnect/
reconnect, the right and left halves of the bar must be
aligned. This alignment may require that the vehicle be
driven onto level ground or rocked from side to side.
To return to the On-Road mode; push the left hand On
Road stabilizer/sway bar button.
WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is reduced. Do not attempt to
drive the vehicle over 18 mph (29 km/h). Driving faster
than 18 mph (29 km/h) may cause loss of control of the
vehicle, which could result in serious injury or death.
Contact your local service center for assistance.
SAFE OFF-ROAD DRIVING — POWER WAGON
ONLY
Off-Road Driving Tips And Vehicle Characteristics
Your vehicle has excellent on and off-road capabilities.
These off-road capabilities will allow you to explore those
wilderness trails where few travel, providing a source of
exciting and satisfying recreation. Before you venture out,
you should contact your local governmental agency to
determine the designated off-road vehicle (ORV) trails or
recreation areas. You should always tread lightly and only
use established roads, trails or ORV recreational areas.
The National Forest Service, Bureau of Land Management,
or local Department of Natural Resources are a wealth of
information and usually have maps with marked trails.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components of
the truck including the fuel tank, transfer case and steering
damper. In addition, this vehicle is equipped with boxed
cross members and fore/aft rails. This additional protec-
tion allows the vehicle to be utilized in severe off-road
situations that would be considered impassable by a nor-
mal truck.

STARTING AND OPERATING 457

CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.
When To Use Low Range
When driving off-road, shift into 4LO (Low Range) for
additional traction or to improve handling and control on
slippery or difficult terrain. Due to the lower gearing, low
range will allow the engine to operate in a higher power
range. This will allow you to idle over obstacles and down
hills, with improved control and less effort. Also, use 4LO
(Low Range) in rain, ice, snow, mud, sand, to get heavy
loads rolling, improve traction, or whenever 4HI (High
Range) traction will not do the job.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum.
•Snow – In heavy snow or for additional control and
traction at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4LO (Low Range) if
necessary. Do not shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin the
wheels and traction will be lost. If you start to slow to a
stop, try turning your steering wheel no more than a ¼
turn quickly back and forth, while still applying throttle.
This will allow the tires to get a fresh biteand help
maintain your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPMs or vehicle speeds because engine brak-
ing may cause skidding and loss of control.
