2009 DODGE RAM 2500 DIESEL engine

The manufacturer supports the use of reformulated gaso-
lines. Properly-blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.Gasoline/Oxygenate BlendsSome fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
Winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and drivability problems and may damage critical
fuel system components.Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of
Methanol.
E-85 Usage In Non-Flex Fuel VehiclesNon-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:•
operate in a lean mode
•
OBD II “Malfunction Indicator Light” on
•
poor engine performance
•
poor cold start and cold drivability
•
increased risk for fuel system component corrosion
376 STARTING AND OPERATING

To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:•
drain the fuel tank (see your authorized dealer)
•
change the engine oil and oil filter
•
disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In GasolineMMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
or not the gasoline contains MMT. It is even more
important to look for gasolines without MMT in Canada,
because MMT can be used at levels higher than those
allowed in the United States. MMT is prohibited in
Federal and California reformulated gasoline.
Materials Added To FuelAll gasolines sold in the United States are required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:•
The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.
•
An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
•
When pulling a heavy load or driving a fully-loaded
vehicle when the humidity is low and the temperature
is high, use a premium unleaded fuel to help prevent
spark knock. If spark knock persists, lighten the load,
or engine piston damage may result.
•
The use of fuel additives which are now being sold as
octane enhancers is not recommended. Many of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
378 STARTING AND OPERATING

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:•
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
•
Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every timethe vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
ADDING FUELThe fuel tank filler tube has a restricting door about 2 in
(50 mm) inside the opening. If using a portable fuel
container, it should have a flexible nozzle long enough to
force open the restricting door.
CAUTION!
•
Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system. Also, a
poorly-fitted aftermarket cap can cause the MIL
(Malfunction Indicator Light) to illuminate due to
fuel vapors escaping from the system.
(Continued)
STARTING AND OPERATING 379

CAUTION! (Continued)
•
A poorly fitting gas cap may cause the MIL to turn
on.
•
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE: When the fuel nozzle “clicks” or shuts off the
fuel tank is full.
WARNING!
•
Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•
Never add fuel to the vehicle when the engine is
running. This is in violation of most state and
federal fire regulations and will cause the MIL to
turn on. NOTE:
Tighten the gas cap 1/4 turn until you hear one
click. This is an indication that the cap is properly
tightened.
If the gas cap is not tightened properly, the Malfunction
Indicator Light will come on, Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
380 STARTING AND OPERATING

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.•
When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to theframe or 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 automatic transmission in
PARK. With 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.
•
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR

WARNING!
Any work done to the vehicles electrical system, or
wiring, should be performed by a qualified automo-
tive technician, if done improperly it may cause
damage to the electrical system wiring and could
result in serious or fatal injury.Towing TipsBefore setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.Automatic TransmissionThe “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
“TOW HAUL” or “OD/OFF” range should be selected.NOTE:
Using the “TOW HAUL” or “OD/OFF” range
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.
This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to the “Main-
tenance Schedule” in Section 8 for the proper mainte-
nance intervals.
NOTE: Check the automatic transmission fluid level
before towing.
Tow/Haul — If EquippedTo reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL OD/OFF” feature ON when
driving in hilly areas or shift the transmission to Drive
position 2 on more severe grades.

Electronic Speed Control — If Equipped

Do not use in hilly terrain or with heavy loads.

When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.

Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling SystemTo reduce potential for engine and transmission over-
heating, take the following actions:
NOTE: Engine power may be temporarily reduced in
order to maintain oil and coolant temperatures under
extreme trailer tow operating conditions.
City Driving
When stopped for short periods of time, put transmission
in neutral and increase engine idle speed.

Highway Driving
Reduce speed.

Air Conditioning
Turn off temporarily.
SNOWPLOWSnowplow Prep Packages are available as a factory-
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
NOTE: Before installation of a snowplow, it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current
Dodge Body Builder’s Guide. See your authorized dealer,
installer or snowplow manufacturer for this information.
There are unique electrical systems that must be con-
nected to properly assure operator safety, and to prevent
overloading vehicle systems.
