138STARTING AND OPERATING
You can switch between DRIVE and ERS mode at
any vehicle speed. When the gear selector is in the
DRIVE position, the transmission will operate
automatically, shifting between all available gears.
Tapping the ERS “-” switch will activate ERS mode,
display the current gear in the instrument cluster,
and set that gear as the top available gear. Once in
ERS mode, tapping “-” or “+” will change the top
available gear.

Electronic Range Select

To exit ERS mode, simply push and hold the
ERS “+” switch until the gear limit display
disappears from the instrument cluster.
NOTE:To select the proper gear position for maximum
deceleration (engine braking), simply push and
hold the ERS “-” switch. The transmission will shift
to the range from which the vehicle can best be
slowed down.
Overdrive Operation

The automatic transmission includes an
electronically controlled Overdrive (FIFTH and SIXTH
gears). The transmission will automatically shift into
Overdrive if the following conditions are present:

The gear selector is in the DRIVE position.
The transmission fluid has reached an
adequate temperature.
The engine coolant has reached an adequate
temperature.
Vehicle speed is sufficiently high.
The TOW/HAUL switch has not been activated.
The driver is not heavily pressing the acceler -
ator.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying
a heavy load, etc., and frequent transmission
shifting occurs, push the TOW/HAUL switch to
activate TOW/HAUL mode. This will improve
performance and reduce the potential for
transmission overheating or failure due to
excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the
transmission will automatically downshift (for
engine braking) when the throttle is closed and/or
during steady braking maneuvers.

TOW/HAUL Switch

1 — GEAR “+” Switch
2 — GEAR “–” Switch
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.

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.

steering wheel, as well as a visual warning in the
instrument cluster display to prompt the driver to
remain within the lane boundaries.
The driver may manually override the haptic
warning by applying torque to the steering wheel at
any time.
When only a single lane marking is detected and
the driver drifts across that lane marking (no turn
signal applied), the LaneSense system provides a
visual warning through the instrument cluster
display to prompt the driver to remain within the
lane.
When only a single lane marking is detected, a
haptic (torque) warning will not be provided.
NOTE:When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provide an
audible and visual warning to the driver if removed.
The system will cancel if the driver does not return
their hands to the wheel.
TURNING LANESENSE ON OR OFF

STARTING AND OPERATING181
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or
suspension components sometimes specified by
purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
TIRE SIZE
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire
size listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
CURB WEIGHT
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with no
occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
LOADING
The actual total weight and the weight of the front
and rear of your vehicle at the ground can best be
determined by weighing it when it is loaded and
ready for operation.

The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR has not
been exceeded. The weight on the front and rear of the
vehicle should then be determined separately to be
sure that the load is properly distributed over the front
and rear axles. Weighing the vehicle may show that the
GAWR of either the front or rear axle has been
exceeded but the total load is within the specified
GVWR. If so, weight must be shifted from front to rear
or rear to front as appropriate until the specified weight
limitations are met. Store the heavier items down low
and be sure that the weight is distributed equally. Stow
all loose items securely before driving.

Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú page 180.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the
trailer in its "loaded and ready for operation"
condition.WARNING!
Do not load your vehicle any heavier than the
GVWR, maximum Payload or maximum front and
rear GAWR. If you do, parts on your vehicle can
break, or it can change the way your vehicle
handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

Adjusting GAIN
NOTE:This should only be performed in a traffic-free envi -
ronment at speeds of approximately 20–25 mph
(30–40 km/h).

1. Make sure the trailer brakes are in good working condition, functioning normally and
properly adjusted. See a trailer dealer if
necessary.

2. Hook up the trailer and make the electrical connections according to the trailer
manufacturer's instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message
should appear in the instrument cluster
display (if the connection is not recognized by the ITBM, braking functions will not be
available), the GAIN setting will illuminate and
the correct type of trailer must be selected
from the instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the
screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the Trailer Brake Type appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake
Type appears on the screen. 8. In a traffic-free environment, tow the trailer on
a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the
trailer wheels turn freely, increase the GAIN
setting.
Repeat steps 8 and 9 until the GAIN setting is at a
point just below trailer wheel lockup. If towing a
heavier trailer, trailer wheel lockup may not be
attainable even with the maximum GAIN setting
of 10.
* The suggested selection depends and may change depending on the customer preferences for braking performance. Condition of the trailer brakes, driving
and road state may also affect the selection.
