GENERAL INFORMATION
Your vehicle is designed to operate on gasoline or Com-
pressed Natural Gas (CNG). Compressed Natural Gas is
made up primarily of methane and is in a gaseous state at
all times.
The manufacturer’s built vehicles equipped with com-
pressed natural gas fueled engines are identified by the
character T in the eighth (engine) position of the Vehicle
Identification Number (V.I.N.).
SAFETY WARNINGS
Natural gas is safe and reliable, when used properly. For
safe operation of your vehicle, observe the following
precautions:
WARNING!
• Your vehicle fuel system has a maximum capacity of
3,600 pounds per square inch gauge (24.8 MPa) com-
pensated to a temperature of 70° F (21° C). The vehicle
should only be filled from refueling equipment incor-
porating temperature compensation to 70° F (21° C).
(Continued)
WARNING! (Continued)
Exceeding the fuel system capacity may result in fuel
system damage and possibly cause injury.
•Do not attempt to force open or tamper with the fuel
fill receptacle. A sudden release of natural gas may
occur, possibly causing injury.
•Natural gas contains an odorant additive and persis-
tent natural gas odor may indicate a leak. If a
persistent natural odor is detected, the cause should
be located and corrected immediately by a qualified
technician.
•Do not park or service your vehicle near any source
of excessive heat or open flame. Never use a paint
oven to cure any paint repairs. The natural gas
storage containers on this vehicle are equipped with
pressure relief devices which vent at 230° F (110° C).
•Do not paint or under coat any natural gas fuel
system components. Unlike gasoline, a compressed
natural gas fuel system is under very high pressure
even when the engine is not running. To avoid risk of
personal injury, any repair to the fuel system should
be performed by a qualified technician.
(Continued)
6 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING! (Continued)
•Natural gas vapors at atmospheric pressure are
lighter than air and will rise and disperse in open
areas. In enclosed areas, natural gas vapor may
collect and form a combustible mixture. If the vehicle
is routinely placed in an enclosed area, the area
should be provided with adequate ventilation and/or
a natural gas detection system. For long term storage,
the manual shutoff valve and individual container
valves should be closed.
•When a vehicle is involved in an accident which has
or may have caused damage to the natural gas fuel
system, the system must be inspected and pressure
tested by a qualified technician before returning the
vehicle to service.
•
Any fuel system component, including the containers,
that has been subjected to fire may not be returned to
service due to reduced pressure capability.
MANUAL SHUT OFF VALVE
The manual one-quarter turn shut off valve is located
inside the protective cover for the tanks. It’s location is
identified by a label on the top of the cover. This valve
isolates the fuel containers from the rest of the fuel system.

INSTRUMENT CLUSTER DESCRIPTIONS
1. CNG Gauge
Shows level of CNG (Compressed Natural Gas) in the
tanks when ignition switch is in the ON/RUN position.
NOTE: Depending on operating/ambient temperature
conditions the CNG gauge may fluctuate.
2. Engine Coolant Temperature
This gauge shows the engine coolant temperature. The
gauge pointer will likely show higher temperatures when
driving in hot weather, up mountain grades, or in heavy
stop and go traffic. If the red Warning Light turns on while
driving, safely bring the vehicle to a stop, and turn off the
engine. DO NOT operate the vehicle until the cause is
corrected.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
(Continued)
WARNING! (Continued)
under the hood yourself, see “Maintaining Your Ve-
hicle.” Follow the warnings under the “Cooling Sys-
tem Pressure Cap” paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H,” turn the engine off immediately and call an
authorized dealer for service.
INSTRUMENT CLUSTER DISPLAY
Your vehicle may be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the STOP/OFF position, opening/closing of
a door will activate the display for viewing, and display
the total miles (kilometers) in the odometer. Your instru-
ment cluster display is designed to display important
information about your vehicle’s systems and features.
12 UNDERSTANDING YOUR INSTRUMENT PANEL

Using a driver interactive display located on the instru-
ment panel, your instrument cluster display can show you
how systems are working and give you warnings when
they aren’t. The steering wheel mounted controls allow
you to scroll through and enter the main menus and
submenus. You can access the specific information you
want and make selections and adjustments.
Instrument Cluster Displays
The main display area will normally display the main
menu or the screens of a selected feature of the main menu.
The main display area also displays “pop up” messages
that consist of approximately 60 possible warning or
information messages. These pop up messages fall into
several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. Most of the
messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long as
there is a stored message, an “i” will be displayed in the
instrument cluster display’s compass/outside temp line.
Examples of this message type are “Right Front Turn Signal
Lamp Out” and “Low Tire Pressure.”
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
•Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition is
in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start.”
•Five Second Unstored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. An example of this
message type is “Automatic High Beams On.”

STARTING PROCEDURES
Your vehicle uses the same starting procedures as de-
scribed in the Ram 1500/2500/3500 Owner’s Manual. No
special starting instructions are required.
NOTE: Periodically the vehicle will automatically switch
from operation on CNG to Gasoline for a short duration,
depending on conditions. This is done for a number of
reasons, including to maintain the freshness and appropri-
ate seasonal blend of gasoline, to ensure maintenance of
the gasoline injectors and/or to meet high-load demands.
FUEL REQUIREMENTS
United States
Use only natural gas which meets the requirements for gas
quality as specified in National Fire Protection Association
NFPA52 and American National Standard ANSI/ AGA
NGV2. Use of natural gas that does not meet these require-
ments may result in starting and driveability problems and
damage to critical fuel system components.
Canada
Use only natural gas which meets the requirements for gas
quality as specified in Canadian Standards Association
(CSA) B51–M1991 G4.1.2 or SAE J1616. Use of natural gas
that does not meet these requirements may result in
starting and driveability problems and damage to critical
fuel system components.
16 STARTING AND OPERATING

ADDING FUEL
1. Open the fuel filler door.
1 — NGV 1 Receptacle
2 — Gasoline Fuel Filling Receptacle
NOTE: There is no fuel filler cap. A flapper door inside the
filler pipe seals the system.
2. Insert the fuel nozzle fully into the filler pipe – the
nozzle opens and holds the flapper door while
refueling.
3. Fill the vehicle with fuel – when the fuel nozzle “clicks”
or shuts off the fuel tank is full.
4. Remove the fuel nozzle and close the fuel door.
Emergency Fuel Can Refueling
Most fuel cans will not open the flapper door.
A funnel is provided to open the flapper door to allow
emergency refueling with a fuel can.
1. Retrieve fuel funnel from the jack kit located under the
front passenger seat.

2. Insert funnel into same filler pipe opening as the fuel
nozzle.
NOTE: Ensure funnel is inserted fully to hold flapper door
open.
3. Pour fuel into funnel opening.
4. Remove funnel from filler pipe, clean off prior to putting
back in the jack kit.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the “Malfunction Indicator Light” to
turn on.
•A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
Adding Compressed Natural Gas (CNG)
The NGV 1 fuel fill receptacle is mounted in the standard
location behind the fuel filler door. The fill dispenser seals
to the receptacle with an O-ring. Replace the O-ring in the
fill receptacle before refueling if it is damaged or missing;
otherwise natural gas can leak while refueling.
Fueling your natural gas powered vehicle can only be
performed at locations specially equipped to refuel natural
gas vehicles.
NOTE: There are a number of NGV1 filler nozzles avail-
able. It may be necessary to rotate the nozzle to ensure
clearance to the fuel filler housing or truck bed.
