Tip Start Feature
Do not press the accelerator. Cycle the ignition switch
briefly to the START position and release it. The starter
motor will continue to run and will automatically disen-
gage when the engine is running.
Keyless Enter-N-Go — Ignition
This feature allows the driver to operate
the ignition switch with the push of a
button, as long as the Remote Start/
Keyless Enter-N-Go key fob is in the
passenger compartment.
Normal Starting
To Turn On The Engine Using The ENGINE
START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing the
ENGINE START/STOP button once.
3. The system takes over and attempts to start the vehicle.
If the vehicle fails to start, the starter will disengage
automatically after 10 seconds. 4. If you wish to stop the cranking of the engine prior to
the engine starting, push the button again.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
To Turn Off The Engine Using ENGINE
START/STOP Button
1. Place the gear selector in PARK, then push and release
the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the gear selector is not in PARK, the ENGINE START/
STOP button must be held for two seconds or three short
pushes in a row with the vehicle speed above 5 mph
(8 km/h) before the engine will shut off. The ignition
switch position will remain in the ACC position until the
gear selector is in PARK and the button is pushed twice
to the OFF position. If the gear selector is not in PARK
and the ENGINE START/STOP button is pushed once,
the instrument cluster will display a “Vehicle Not In
Park” message and the engine will remain running.
Never leave a vehicle out of the PARK position, or it
could roll.322 STARTING AND OPERATING

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the ignition must be turned to
the ON/RUN mode (engine running or not) and the brake
pedal must be pressed.
Six–Speed Automatic Transmission — If Equipped
Chassis Cab models (with automatic transmission) may
use either the AS66RC transmission (which is equipped
with a Power Take-Off (PTO) access cover on the side of the
transmission case), or the 66RFE transmission (which has
no PTO access cover).
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The gear selector is mounted on the right side of the
steering column. You must press the brake pedal to move
the gear selector out of PARK (refer to “Brake/
Transmission Shift Interlock System” in this section). To
drive, move the gear selector from PARK or NEUTRAL to
the DRIVE position. Pull the gear selector toward you
when shifting into REVERSE or PARK, or when shifting
out of PARK. The electronically-controlled transmission provides a pre-
cise shift schedule. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual downshifts
can be made using the Electronic Range Select (ERS) shift
control (refer to “Electronic Range Select [ERS] Operation”
in this section for further information). Pushing the ERS
(-/+) switches (on the gear selector) while in the DRIVE
position will select the highest available transmission gear,
and will display that gear limit in the instrument cluster as
1, 2, 3, etc. Some models will display both the selected gear
limit, and the actual current gear, while in ERS mode.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range. 5STARTING AND OPERATING 327

instrument cluster, and set that gear as the top available
gear. Once in ERS mode, tapping (-) or (+) 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.
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.
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 over-
speed.
Overdrive Operation
The automatic transmission includes an electronically con-
trolled 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.Column Gear Selector 5STARTING AND OPERATING 333

• The transmission fluid has reached an adequate tem-
perature.
• The engine coolant has reached an adequate tempera-
ture.
• Vehicle speed is sufficiently high.
• The TOW/HAUL switch has not been activated.
• The driver is not heavily pressing the accelerator.
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 maneu-
vers. 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. TOW/HAUL Switch334 STARTING AND OPERATING

POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with PTO Prep and the
AS66RC automatic six-speed, 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 instrument cluster screen and select mobile PTO
mode. Details of the PTO selection modes and further PTO
information is available at the Ram Truck Bodybuilders
web site. www.rambodybuilder.com
AS66RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS66RC) 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:
• Transmission in PARK position (vehicles equipped with
automatic 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 pro-
vided circuits.
The instrument cluster will display a  PTO On  message for
five seconds if the above conditions are met. Otherwise, the
instrument cluster will display a message  To Operate PTO
Shift To Park  indicating what operator action should be
taken to engage the PTO mode.336 STARTING AND OPERATING

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 operate 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 be used respectively. To
disengage PTO operation and return to “standard vehicle
operation” simply toggle the PTO switch to the OFF
position.
The torque converter clutch (TCC) will automatically en-
gage at engine speeds above 1,200 RPM (engine speed) in
PTO stationary mode. Once engaged, the TCC will remain
applied and will not disengage until the engine speed falls
below 1,000 RPM. TCC engagement is desirable for certain
types of PTO applications (Automatic Transmission Only).
To operate the PTO via a remote switch, the customer must
make sure the above conditions are met. It is vital for
proper operation that the PTO and remote have been
installed correctly, paying special attention to ensure the
vehicle provided wiring has been connected properly. This
is the responsibility of the installer of the PTO and
switches/remote system. It is the responsibility of the PTO manufacturer to ensure that their electrical (switches and
remote) system is compatible with the vehicle’s electrical
architecture and software functionality.
NOTE: Single set speed can be programmed via the PTO
menu on the instrument cluster display. Further details are
available at the Ram Truck Bodybuilders web site located
at rambodybuilder.com
Mobile Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
• Mobile mode is activated via the menu on the instru-
ment cluster display.
• (ON/OFF) switch has been activated.
• Vehicles with automatic transmission must be in PARK
or DRIVE.
• Parking brake must not be applied.
• Brake pedal must not be applied.
• No vehicle, brake or clutch switch faults present.
• Vehicle engine must be running. 5STARTING AND OPERATING 337

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) for normal
street and highway conditions on dry, hard surfaced roads.
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 by
rotating the 4WD Control Switch to the desired position.
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 on
the lower left hand corner of the 4WD Control Switch. The transfer case NEUTRAL position is to be used for recre-
ational 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 and
4LOW) 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. 5STARTING AND OPERATING 343

When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
• When the parking brake is applied and the automatic
transmission is placed in gear, the “Brake Warning
Light” will flash. If vehicle speed is detected, a chime
will sound to alert the driver. Fully release the parking
brake before attempting to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application. When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. For vehicles equipped
with an automatic transmission, apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK.
The parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!• Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Allowing children to be 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 the key fob in or near the vehicle, or in a
location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-N-Go
in the ACC or ON/RUN mode. A child could operate
power windows, other controls, or move the vehicle. (Continued)Parking Brake Release 5STARTING AND OPERATING 351
