ESP Ram 3500 2019 Repair Manual

568 TECHNICAL SPECIFICATIONS
Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Properly
blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.Designated TOP TIER Detergent Gasoline contains a
higher level of detergents to further aide in mini -
mizing engine and fuel system deposits. When avail -
able, the usage of TOP TIER Detergent gasoline is
recommended. Visit www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers. Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and
diaphragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen
-
ates such as ethanol.
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol are
not the responsibility of the manufacturer and may void or
not be covered under New Vehicle Limited Warranty.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use of
these blends may result in starting and drivability
problems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the Malfunction Indicator Light to illuminate.
Please observe pump labels as they should clearly
communicate if a fuel contains greater than 15% ethanol
(E-15).

TECHNICAL SPECIFICATIONS 569
Do Not Use E-85 In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
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.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on Compressed
Natural Gas (CNG) or Liquid Propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are not
the responsibility of the manufacturer and may void or not
be covered under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) 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 emissions
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 gaso -
line retailer whether the gasoline contains MMT. MMT is
prohibited in Federal and California reformulated gasoline.

Fuel System Cautions
NOTE:
Intentional tampering with the emissions control system can
result in civil penalties being assessed against you.
Carbon Monoxide Warnings
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
• The use of leaded gasoline is prohibited by Federal law. Using leaded gasoline can impair engine perfor -
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition malfunctions can cause the catalytic converter to over -
heat. 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 an authorized dealer for service assistance.

• The use of fuel additives, which are now being sold as octane enhancers, is not recommended. Most 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 and may void or not
be covered under the New Vehicle Limited Warranty.
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 time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.

Regulatory And Safety Information
USA/CANADA
Exposure to Radio Frequency Radiation
The radiated output power of the internal wireless radio is
far below the FCC and IC radio frequency exposure limits.
Nevertheless, the wireless radio will be used in such a
manner that the radio is 8 in (20 cm) or further from the
human body.
The internal wireless radio operates within guidelines found
in radio frequency safety standards and recommendations,
which reflect the consensus of the scientific community.
The radio manufacturer believes the internal wireless radio
is safe for use by consumers. The level of energy emitted is
far less than the electromagnetic energy emitted by wireless
devices such as mobile phones. However, the use of wireless
radios may be restricted in some situations or environments,
such as aboard airplanes. If you are unsure of restrictions,
you are encouraged to ask for authorization before turning
on the wireless radio.
The following regulatory statement applies to all Radio
Frequency (RF) devices equipped in this vehicle:This device complies with Part 15 of the FCC Rules and with
Industry Canada license-exempt RSS standard(s). Operation
is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received,
including interference that may cause undesired opera -
tion.
NOTE:
Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
NOTE:
• This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation.
