ESP Ram 3500 Chassis Cab 2020 Repair Manual

400TECHNICAL SPECIFICATIONS
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 perfor -
mance.
Designated TOP TIER Detergent Gaso -
line contains a higher level of deter -
gents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of TOP TIER Deter -
gent gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Deter -
gent Gasoline Retailers.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these mate -
rials 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 oxygenates 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.
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 manufac -
turer and may void or not be covered under the
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).

(Continued)
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic addi -
tive 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 manufac -
turer 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 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 performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni -
tion 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 malfunc -
tioning 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 perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
CAUTION! (Continued)
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 maintenance. 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.

Fuel In Oil Dilution — Must Adhere To
Required Oil Change Interval
Fuel dilution of lubricating oil has been
observed with the use of biodiesel fuel. Fuel in
oil must not exceed 5%. To ensure this limit is
met your oil change interval must be main -
tained to the following schedule:
Ram 3500/4500/5500 Chassis Cab
— 12,500 Miles (20,000 km)*
(*unless otherwise notified with a oil service
message)
VEHICLE SPECIFCATIONS
NOTE:
A chime will sound if the vehicle speed exceeds
75 mph (120 km/h).
CAUTION!
Under no circumstances should oil change
intervals exceed 12,500 miles
(20,000 km) if operation occurs with
greater than 5% biodiesel blends. Oil
change intervals should not exceed
6 months in either case. Failure to comply
with these Oil Change requirements for
vehicles operating on biodiesel blends up
to B20 may result in premature engine
wear. Such wear is not covered by the New
Vehicle Limited Warranty.
B20 Biodiesel capable: The engine may
suffer severe damage if operated with
concentrations of Biodiesel higher than
20%.

SAFETY AND GENERAL INFORMATION
Safety Guidelines
Ensure that all persons read this manual care -
fully before using the system. It contains
instructions on how to use the system in a safe
and effective manner.
Do NOT attach any object to the touchscreen.
Doing so can result in damage to the touch -
screen.
Please read and follow these safety precau -
tions. Failure to do so may result in injury or
property damage.
Glance at the screen only when safe to do so.
If prolonged viewing of the screen is required,
park in a safe location and set the parking
brake.
Stop use immediately if a problem occurs.
Failure to do so may cause injury or damage
to the product. Return it to an authorized
dealer for repair.
Ensure the volume level of the system is set
to a level that still allows you to hear outside
traffic and emergency vehicles.
Safe Usage Of The Uconnect System
Read all instructions in this manual carefully
before using your system to ensure proper
usage.
The Uconnect system is a sophisticated elec -
tronic device. Do not let young children use
the system.
Permanent hearing loss may occur if you play
your music or the system at loud volumes.
Exercise caution when setting the volume on
the system.
Keep drinks, rain and other sources of mois -
ture away from the system. Besides damage
to the system, moisture can cause electric
shocks as with any electronic device.
NOTE:
Many features of this system are speed depen -
dent. For your own safety, it is not possible to
use some of the touchscreen features while the
vehicle is in motion.
Exposure To Radio Frequency Radiation
The internal wireless radio operates within
guidelines found in radio frequency safety stan -
dards and recommendations, which reflect the
consensus of the scientific community. The
radio manufacturer believes the internal wire -
less radio is safe for use by consumers. The
level of energy emitted is far less than the elec -
tromagnetic energy emitted by wireless devices
such as mobile phones. However, the use of
wireless radios may be restricted in some situa-
tions 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.
WARNING!
ALWAYS drive safely with your hands on the
steering wheel. You have full responsibility
and assume all risks related to the use of the
Uconnect features and applications in this
vehicle. Only use Uconnect when it is safe to
do so. Failure to do so may result in an
accident involving serious injury or death.
