STARTING AND OPERATING139
The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL
mode has been activated. Pushing the switch a
second time restores normal operation. Normal
operation is always the default at engine start-up.
If TOW/HAUL mode is desired, the switch must be
pushed each time the engine is started.
Torque Converter Clutch
A feature designed to improve fuel economy has
been included in the automatic transmission on
your vehicle. A clutch within the torque converter
engages automatically at calibrated speeds. This
may result in a slightly different feeling or response
during normal operation in the upper gears. When
the vehicle speed drops or during some
accelerations, the clutch automatically
disengages.
NOTE:
The torque converter clutch will not engage,
until the transmission fluid and engine coolant
are warm (usually after 1 to 3 miles (2 to 5 km)
of driving). Because engine speed is higher
when the torque converter clutch is not
engaged, it may seem as if the transmission is
not shifting properly when cold; this is normal.
Using the Electronic Range Select (ERS) shift
control, when the transmission is sufficiently
warm, will demonstrate that the transmission is
able to shift into and out of Overdrive.
If the vehicle has not been driven for several
days, the first few seconds of operation after
shifting the transmission into gear may seem
sluggish. This is due to the fluid partially
draining from the torque converter into the
transmission. This condition is normal and will
not cause damage to the transmission. The
torque converter will refill within five seconds
after starting the engine.
AUXILIARY SWITCHES — IF EQUIPPED
There can be up to six auxiliary switches located in
the lower switch bank of the instrument panel
which can be used to power various electronic
devices and Power Take Off (PTO). If equipped, it
will take the place of the sixth auxiliary switch.
Connections to the switches are found under the
hood in the connectors attached to the auxiliary
Power Distribution Center.
You have the ability to configure the functionality of
the auxiliary switches via the instrument cluster
display. All switches can now be configured for
setting the switch type operation to latching or
momentary, power source of either battery or
ignition, and ability to hold last state across key
cycles.
NOTE:Holding last state conditions are met when switch
type is set to latching and power source is set to
ignition.
For further information on using the auxiliary
switches, please refer to the Ram Body Builder’s
Guide by accessing

and choosing the
appropriate links.
WARNING!
Do not use the TOW/HAUL feature when driving
in icy or slippery conditions. The increased
engine braking can cause the rear wheels to
slide, and the vehicle to swing around with the
possible loss of vehicle control, which may
cause an accident possibly resulting in personal
injury or death.4

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

144STARTING AND OPERATING
NOTE:The transfer case N (Neutral) button is located on
the lower left hand corner of the four-wheel drive
Control Switch. The transfer case N (Neutral)
position is to be used for recreational towing only
Úpage 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, turn the control switch back to 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, 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 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.
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.
To retry a shift: return the control switch back to
the original position, make certain all shift
requirements have been met, wait five seconds
and try the shift again.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.

146STARTING AND OPERATING
4H
Four-Wheel Drive Lock High Range — This range
locks the front and rear driveshafts together
forcing the front and rear wheels to rotate at the
same speed. Additional traction for loose, slippery
road surfaces only.
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.
4L
Four-Wheel Drive Low Range — This range locks
the front and rear driveshafts together forcing 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).
This transfer case is intended to be driven in the
2H position for normal street and highway
conditions such as dry, hard surfaced roads.
When additional traction is required, the 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 gear selector
to the desired positions once the appropriate
speed and gear requirements are met
Ú page 144. 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 Transfer Case Position Indicator Light in the
instrument cluster will alert the driver that the
vehicle is in four-wheel drive and that the front and
rear driveshafts are locked together. This light will
illuminate when the transfer case is shifted into
either the 4H or 4L position. There is no light for the
2H or N (Neutral) positions on some models.
When operating your vehicle in 4L, the engine
speed is approximately three times that of the
two-wheel drive 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 four-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 drivetrain.
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.
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.
NOTE:Delayed shifts out of four-wheel drive may be expe -
rienced due to uneven tire wear, low or uneven tire
pressures, excessive vehicle loading, or cold
temperatures.
Shifting Procedure — Manually Shifted
Transfer Case
2H TO 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 vehicle in motion, the transfer
case will engage/disengage faster if you
momentarily release the accelerator pedal after
completing the shift. Apply a constant force when
shifting the transfer case lever.
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 shafts 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.
23_DPF_OM_EN_USC_t.book Page 146
Page 149 of 444

STARTING AND OPERATING147
2H OR 4H TO 4L
NOTE:
When shifting into or out of 4L some gear noise
may be heard. This noise is normal and is not detri -
mental to the vehicle or occupants.
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h),
shift the transmission into NEUTRAL. 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 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 the transmission into Neutral, hold
your foot on the brake, and turn the engine OFF.
Complete the range shift to the desired position.
Shifting into or out of 4L is possible with the
vehicle completely stopped, however difficulty
may occur due to the mating teeth not being prop -
erly aligned. Several attempts may be required for
teeth alignment and shift completion to occur.
The preferred 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).
Do not attempt to shift into or out of 4L while the
transmission is in gear.
Transfer Case Position Indicator Light
The Transfer Case Position Indicator Light in the
instrument cluster is used to alert the driver that
the front axle is fully engaged and all four wheels
are driving.
LIMITED-SLIP DIFFERENTIAL
The limited-slip differential provides additional
traction on snow, ice, mud, sand and gravel,
particularly when there is a difference between the
traction characteristics of the surface under the
right and left rear wheels. During normal driving
and cornering, the limited-slip unit performs
similarly to a conventional differential. On slippery
surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the
better traction.
The limited-slip differential is especially helpful
during slippery driving conditions. With both rear
wheels on a slippery surface, a slight application of
the accelerator will supply maximum traction.
When starting with only one rear wheel on an
excessively slippery surface, slight momentary
application of the parking brake may be necessary
to gain maximum traction. Care should be taken to avoid sudden
accelerations when both rear wheels are on a
slippery surface. This could cause both rear wheels
to spin, and allow the vehicle to slide sideways on
the crowned surface of a road or in a turn.
POWER TAKE OFF (PTO) OPERATION —
IF EQUIPPED
This vehicle when equipped with PTO Prep and the
AS66RC/AS69RC automatic 6-speed, will allow for
an aftermarket upfit with a transmission driven
PTO. The customer will have the ability to operate
the PTO in either a “stationary”, “mobile” or
“remote” mode. The vehicles will be factory set to
the “stationary” mode. To select a different mode,
or to change any other PTO setting, you will need to
enter the commercial vehicle menu on the
instrument cluster screen. Details of the PTO
selection modes and further PTO information is
available at the Ram Truck Body Builder’s web site:
https://www.ramtrucks.com/ram-commercial/
body-builders-guide.html
WARNING!
On vehicles equipped with a limited-slip
differential never run the engine with one rear
wheel off the ground since the vehicle may drive
through the rear wheel remaining on the ground.
You could lose control of the vehicle.

(Continued)
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel
operate the ACC system.
Adaptive Cruise Control Buttons
Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the
current ACC system settings. The information it
displays depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off
button until one of the following appears in the
instrument cluster display:
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
Will bring the vehicle to a complete stop
while following a vehicle ahead and hold
the vehicle for approximately two seconds
in the stop position. At this point, there will
be an “ACC May Cancel Soon” chime and
warning to the driver. When ACC is
canceled, the system will release the
brakes and the driver must take over
braking. The system can be resumed
when the vehicle ahead drives off by
releasing the brake and pushing the
resume button on the steering wheel.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (i.e., in highway construction zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving
at a constant speed.

154STARTING AND OPERATING
NOTE:
While in ACC mode, when the vehicle comes to
a complete stop longer than two seconds, the
system will cancel. The driver will have to apply
the brakes to keep the vehicle at a standstill.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button. U.S. Speed (mph)
Pushing the SET (+)
, or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) buttons, the new set speed will be the
current speed of the vehicle. When ACC Is Active
When you use the SET
(-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system applies the brake down to a full
stop when following a vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for Adaptive
Cruise Control (ACC) can be set by varying the
distance setting between four bars (longest), three
bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed,
ACC calculates and sets the distance to the vehicle
ahead. This distance setting displays in the
instrument cluster display.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.
