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

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.

150STARTING AND OPERATING
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC
(cancel) button, or normal brake pressure while
slowing the vehicle will deactivate the Cruise
Control system without erasing the set speed from
memory.
The following conditions will also deactivate the
Cruise Control system without erasing the set
speed from memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Pushing the on/off button or placing the ignition in
the OFF position, erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently Ú page 149.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 427.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
For the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú
page 389.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the hook retainers of the vehicle
hitch. Cross the chains under the trailer
tongue and allow enough slack for turning
corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL. Always, block or "chock" the trailer
wheels.
GCWR must not be exceeded.
WARNING!
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized
WARNING!
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.

RECREATIONAL TOWING — TWO-WHEEL
D
RIVE MODELS
DO NOT flat tow this vehicle. Damage to the
drivetrain will result.
Recreational towing (for two-wheel drive models) is
allowed ONLY if the rear wheels are OFF the
ground. This may be accomplished using a tow
dolly or vehicle trailer. If using a tow dolly, follow
this procedure:

1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer's
instructions.

2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic transmission in PARK.
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer's instructions.
5. Turn the ignition to the OFF position and remove the key fob.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the
straight position.
RECREATIONAL TOWING —
F
OUR-WHEEL DRIVE MODELS
NOTE:Both the manual shift and electronically shifted
transfer cases must be shifted into N (Neutral) for
recreational towing. Automatic transmissions must
be shifted into PARK for recreational towing. Refer
to the following for the proper transfer case N
(Neutral) shifting procedure for your vehicle.
CAUTION!
Towing with the rear wheels on the ground will
cause severe transmission damage. Damage
from improper towing is not covered under the
New Vehicle Limited Warranty.
Do not disconnect the driveshaft because
fluid may leak from the transmission, causing
damage to internal parts.
CAUTION!
DO NOT dolly tow any four-wheel drive vehicle.
Towing with only one set of wheels on the
ground (front or rear) will cause severe trans -
mission and/or transfer case damage. Tow
with all four wheels either ON the ground, or
OFF the ground (using a vehicle trailer).
Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage
to the transfer case.
Before recreational towing, the transfer case
must be in N (Neutral). To be certain the
transfer case is fully in N (Neutral), perform
the procedure outlined under “Shifting Into N
(Neutral)”. Internal transmission damage will
result, if the transfer case is not in N (Neutral)
during towing.
The transmission must be placed in PARK for
recreational towing.
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
Do not disconnect the rear driveshaft because
fluid will leak from the transfer case, causing

23_DPF_OM_EN_USC_t.book Page 195

196STARTING AND OPERATING
Shifting Into N (Neutral)
Use the following procedure to prepare your
vehicle for recreational towing.

1. Bring the vehicle to a complete stop on level
ground, with the engine running. Firmly apply
the parking brake.

2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal. 4. Shift the transfer case into N (Neutral):With manual shift transfer case, shift the
transfer case lever into N (Neutral).
With electronically shifted transfer case,
push and hold the transfer case N (Neutral)
button. Some models have a small,
recessed "N" button (at the center of the
transfer case switches) that must be
pressed using a ballpoint pen or similar
object. Other models have a rectangular N
(Neutral) switch, below the rotary transfer
case control knob. The N (Neutral) indicator
light will blink while the shift is in progress.
The light will stop blinking (stay on solid)
when the shift to N (Neutral) is complete.
After the shift is completed and the N
(Neutral) light stays on, release the N
(Neutral) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that there is no vehicle movement.
8. Repeat steps 6 and 7 with automatic transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn off the engine.
For vehicles with Keyless Enter ‘n Go™, push
and hold the ENGINE START/STOP button until
the engine shuts off. 10. Shift the transmission into PARK.
11. Place the ignition in the OFF position, and
remove the key fob.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake.
NOTE:With electronically shifted transfer case:
Steps 2 through 3 are requirements that must
be met before pushing the N (Neutral) button,
and must continue to be met until the shift has
been completed. If any of these requirements
are not met before pushing the N (Neutral)
button or are no longer met during the shift, the
N (Neutral) indicator light will flash continuously
until all requirements are met or until the N
(Neutral) button is released.
The ignition must be in the ON/RUN position for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is not
in the ON/RUN position, the shift will not take
place and no position indicator lights will be on
or flashing.
A flashing N (Neutral) position indicator light
indicates that shift requirements have not been
met.
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 driveshafts from the powertrain, and will
allow the vehicle to roll, even if the automatic
transmission is in PARK. The parking brake
should always be applied when the driver is not
in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain
that the transfer case is fully in N (Neutral)
before recreational towing to prevent damage to
internal parts.

23_DPF_OM_EN_USC_t.book Page 196

STARTING AND OPERATING197
Shifting Out Of N (Neutral)
Use the following procedure to prepare your
vehicle for normal usage:

1. Bring the vehicle to a complete stop, leaving
it connected to the tow vehicle.

2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine, and shift the transmission into NEUTRAL.
With manual shift transfer case, shift the
transfer case lever to the desired position.
With electronically shifted transfer case
with rotary selector switch, push and hold
the transfer case N (Neutral) button until
the N (Neutral) indicator light turns off. After
the N (Neutral) indicator light turns off,
release the N (Neutral) button. After the N
(Neutral) button has been released, the
transfer case will shift to the position indi -
cated by the selector switch.
With electronically shifted transfer case
with push-button selector switch, push and
hold the switch for the desired transfer case
position, until the N (Neutral) indicator light
turns off and the desired position indicator
light turns on.
NOTE:When shifting the transfer case out of N (Neutral),
turning the engine off is not required, but may be
helpful to avoid gear clash. With 8-speed auto -
matic transmission, the engine must remain
running, since turning the engine off will shift the
transmission to PARK (and the transmission must
be in NEUTRAL for the transfer case to shift out of
NEUTRAL).
5. Turn the engine off. Shift automatic transmission into PARK. On 8-speed
transmissions the shifter will automatically
select PARK when the engine is turned off.
6. Release the brake pedal.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal, and check that the vehicle
operates normally.
NOTE:With electronically shifted transfer case:
Steps 3 and 4 are requirements that must be
met before pushing the button to shift out of N
(Neutral), and must continue to be met until the
shift has been completed. If any of these
requirements are not met before pushing the
button or are no longer met during the shift, the
N (Neutral) indicator light will flash continuously
until all requirements are met or until the button
is released.
The ignition must be in the ON/RUN position for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is not
in the ON/RUN position, the shift will not take
place and no position indicator lights will be on

A flashing N (Neutral) position indicator light
indicates that shift requirements have not been
met.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other
slippery surfaces may cause the driving wheels to
pull erratically to the right or left. This phenomenon
occurs when there is a difference in the surface
traction under the rear (driving) wheels.

23_DPF_OM_EN_USC_t.book Page 197

SAFETY271
(Continued)
REAR SEAT REMINDER ALERT (RSRA)
RSRA alerts you through a visual and auditory
notification of the possible presence of an object,
passenger, or pet in the rear seats if a rear door
was opened up to 10 minutes before the ignition
was placed in the ON/RUN position. RSRA does not
directly detect objects, passengers, or pets in the
rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on
the instrument cluster display and sounds an
auditory alert upon the driver placing the ignition in
the OFF position to exit the vehicle.
To enable or disable RSRA, see Ú page 199.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Hill Start Assist (HSA),
Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), and Traction Control
System (TCS). These systems work together to
enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer
Sway Control (TSC) and Hill Descent Control (HDC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.
WARNING!
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.
