In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the
transmission is in DRIVE. For example, if you set the
transmission gear limit to 4 (fourth gear), the transmis-
sion will not shift above fourth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever 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 the ERS (-) or
(+) switch will change the top available gear.

To exit ERS mode, simply push and hold the ERS (+)
switch until the gear limit display disappears from the
instrument cluster.
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.

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 Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID). 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.

POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with PTO Prep and either
the AS69RC automatic six-speed or G-56 manual six-
speed transmissions, will allow for an aftermarket upfit
with a transmission driven PTO (power take off). The
customer will have the ability to operate the PTO in
either a “stationary” or “mobile” mode. The vehicles will
be factory set to the “stationary” mode. To select ’mobile
mode’ You will need to enter the commercial vehicle
menu on the EVIC/DID screen and select mobile PTO
mode. Details of the PTO selection modes and further
PTO information is available at the Ram Truck Body-
builders web site. www.rambodybuilder.com
AS69RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS69RC) operates at
torque converter turbine speed. The turbine speed will be

less than engine speed when the torque converter clutch
is not engaged and will be same as engine speed when
the torque converter clutch is engaged.
Stationary Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
•Be in PARK position (vehicles equipped with auto-
matic transmission.)
• PTO switch has been activated.
• Parking brake applied (vehicles equipped with
manual transmission).
• Brake pedal must not be applied.
• Vehicle engine must be running.
• No vehicle, brake or clutch switch faults present. •
PTO must be correctly installed using the vehicle
provided circuits.
The Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID) will display a PTO
On message for five seconds if the above conditions are
met. Otherwise, the EVIC/DID will display a message
To Operate PTO Shift To Park indicating what operator
action should be taken to engage the PTO mode.
The customer has the choice to operate the PTO by
utilizing the cruise control switches or by utilizing a
remote control (provided by the PTO supplier). To oper-
ate the feature using the cruise control switches, the
customer must first activate the PTO switch which will
turn on the PTO. In order to increase or decrease the
engine idle speed, to optimize the PTO function, the
“RESUME/ACCEL” and “DECEL” cruise switches can

Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument cluster) will
display the level of DEF remaining in the tank. Refer to
“Instrument Cluster” and “Instrument Cluster Descrip-
tions” in “Understanding Your Instrument Panel” for
further information.
NOTE:Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in your
vehicle.
Another factor is that outside temperature can affect DEF
consumption. In cold conditions, 12° F (-11° C) and
below, the DEF gauge needle can stay on a fixed position
and may not move for extended periods of time. This is
a normal function of the system.
DEF Fill Procedure
NOTE: Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type. 1. Remove cap from DEF tank (located on drivers side of
the vehicle or in fuel door).

254 STARTING AND OPERATING
Page 259 of 338

4. Reinstall cap onto DEF tank.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C), your
vehicle is equipped with an automatic DEF heating
system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended period of time
with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it
could be damaged. Therefore, do not overfill the DEF
tank.
The DEF tank on these vehicles is designed with a large
amount of full reserve. So the level sensor will indicate a
Full reading even before the tank is completely full. To
put it another way, there’s additional storage capacity in
the tank above the Full mark that’s not represented in the
gauge. You may not see any movement in the reading –
even after driving up to 2,000 miles in some cases.The difference this makes varies by vehicle. Heavy-duty
pickup trucks have a 5.7-gallon tank that will display a
Full reading when about 90 percent full. This means that
drivers can consume at least 10 percent of a truly full DEF
tank without seeing any visible change in the gauge
reading. Chassis cabs have a larger 9-gallon tank, and
will display a Full reading when about 75 percent full. So
drivers can consume 25 percent of a truly full DEF tank
without seeing any visible change in the gauge reading.
Extra care should be taken when filling with portable
containers to avoid overfilling. Note the level of the DEF
gauge in your instrument cluster. On pickup applica-
tions, you may safely add a maximum of 2 gallons of DEF
from portable containers when your DEF gauge is read-
ing ½ full. On Chassis Cab applications a maximum of
2 gallons may be added when the DEF gauge is reading
¾ full.

The condition of the air cleaner filter is monitored by the
Engine Control Module. The “SERVICE AIR FILTER”
message will display in the Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID)
when service is required. Refer to “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
The “SERVICE AIR FILTER” message could be displayed
periodically. This is because engine air flow requirements
change based on driving conditions. As the filter becomes
more restrictive and air flow requirements increase the
“SERVICE AIR FILTER” message will be displayed. The
message may not be displayed in subsequent drive cycles
if the same conditions are not met. The air filter element
should be replaced within 250 miles (402 km) from the
first time this message is displayed to ensure proper
engine operation during all driving conditions.CAUTION!
Driving with a restricted air filter can cause engine
damage. Driving in dusty environments for extended
periods will lead to rapid air filter plugging. Action
should be taken as soon as the “SERVICE AIR
FILTER” message is displayed.
If the vehicle experiences a sudden loss of engine power
while being driven in heavy snow or rain, or when
plowing snow, and/or the “SERVICE AIR FILTER” mes-
sage is displayed on the EVIC/DID along with a chime
that repeats every 60 seconds, visually inspect the air
filter for snow/ice build up or extreme water saturation.
If the air filter is not damaged, remove all snow/ice and
reinstall air filter. If the air filter is damaged, replace filter
element.
