Stain Repel Fabric Cleaning Procedure —
If Equipped
Stain Repel seats may be cleaned in the following
manner:
Remove as much of the stain as possible by
blotting with a clean, dry towel.
Blot any remaining stain with a clean, damp
towel.
For tough stains, apply Mopar® Total Clean, or
a mild soap solution to a clean, damp cloth and
remove stain. Use a fresh, damp towel to
remove soap residue.
For grease stains, apply Mopar® Multi-Purpose
Cleaner to a clean, damp cloth and remove
stain. Use a fresh, damp towel to remove soap
residue.
Do not use any harsh solvents or any other form
of protectants on Stain Repel products.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the
fabric.
If the belts need cleaning, use a mild soap solution
or lukewarm water. Do not remove the belts from
the vehicle to wash them. Dry with a soft cloth.
Sun damage can also weaken the fabric. Replace
the belts if they appear frayed or worn or if the
buckles do not work properly.
NOTE:If the belts retract slowly, inspect the upper turning
loop for soiling. If soiling is present, clean with a
wet soft cloth until all residue is removed.
PLASTIC AND COATED PARTS
Use Mopar® Total Clean to clean vinyl upholstery.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable, and
if used in closed areas they may cause
respiratory harm.
WARNING!
A frayed or torn seat belt could rip apart in a
collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the seat belt
system. If your vehicle is involved in a collision,
or if you have questions regarding seat belt or
retractor conditions, take your vehicle to an
authorized FCA dealer or authorized FCA
Certified Collision Care Program facility for
inspection.
CAUTION!
Direct contact of air fresheners, insect repel -
lents, suntan lotions, or hand sanitizers to the

Cleaning Plastic Instrument Cluster
Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When cleaning
the lenses, care must be taken to avoid scratching
the plastic.
Clean with a wet soft cloth. A mild soap solution
may be used, but do not use high alcohol content
or abrasive cleaners. If soap is used, wipe clean
with a clean damp cloth. Dry with a soft cloth.
LEATHER SURFACES
Mopar® Total Clean is specifically recommended
for leather upholstery.
Your leather upholstery can be best preserved by
regular cleaning with a damp soft cloth. Small
particles of dirt can act as an abrasive and damage
the leather upholstery and should be removed
promptly with a damp cloth. Stubborn soils can be
removed easily with a soft cloth and Mopar® Total
Clean. Care should be taken to avoid soaking your
leather upholstery with any liquid. Please do not
use polishes, oils, cleaning fluids, solvents,
detergents, or ammonia-based cleaners to clean
your leather upholstery.
NOTE:If equipped with light colored leather, it tends to
show any foreign material, dirt, and fabric dye
transfer more so than darker colors. The leather is
designed for easy cleaning, and the manufacturer
recommends Mopar® Total Care leather cleaner
applied on a cloth to clean the leather seats as
needed.GLASS SURFACES
All glass surfaces should be cleaned on a regular
basis with Mopar® Glass Cleaner, or any
commercial household-type glass cleaner. Never
use an abrasive type cleaner. Use caution when
cleaning the inside rear window equipped with
electric defrosters or windows equipped with radio
antennas. Do not use scrapers or other sharp
instruments that may scratch the elements.
When cleaning the rearview mirror, spray cleaner
on the towel or cloth that you are using. Do not
spray cleaner directly on the mirror.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
instrument panel, visible through the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off),
the brakes will still function. However, you will
experience a substantial increase in braking effort
to stop the vehicle. If either the front or rear hydraulic system loses
normal braking capability, the remaining system
will still function with some loss of overall braking
effectiveness. This will be evident by increased
pedal travel during application, greater pedal force
required to slow or stop, and activation of the
Brake Warning Light and/or the Anti-Lock Brake
System (ABS) Warning Light during brake use.
HYDRAULIC BRAKE ASSIST —
I
F EQUIPPED
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the power
steering system. You may experience some
clicking or hissing noises from the hydro-boost
system during hard braking conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil
before tightening.

FUEL SPECIFICATIONS
The Cummins® Turbo Diesel engine has been
developed to take advantage of the high energy
content and generally lower cost Number 2 Ultra
Low Sulfur diesel fuel or Number 2 Ultra Low Sulfur
climatized diesel fuels. Experience has shown that
it also operates on Number 1 Ultra Low Sulfur
diesel fuels or other fuels within specification.
NOTE:
If you accidentally fill the fuel tank with gasoline
on your diesel vehicle, Do not start the vehicle.
If you restart your vehicle you risk damaging the
engine and fuel system. Please call an autho-
rized dealer for service.
A maximum blend of 20% biodiesel meeting
ASTM specification D-7467 may be used with
your Cummins® diesel engine. (Models config -
ured with B20 Capability.)
In addition, commercially available fuel addi -
tives are not necessary for the proper operation
of your Cummins® diesel engine. However, if
seasonably adjusted fuel is not available and
you are operating below 20°F (-6°C), Mopar®
Premium Diesel Fuel Treatment (or equivalent)
may be beneficial to avoid fuel gelling.
Number 1 Ultra Low Sulfur diesel fuel should
only be used where extended arctic conditions
(0°F or -18°C) exist.
BIODIESEL FUEL REQUIREMENTS
Chassis Cab Models Ordered With B20
Option
Your vehicle has been validated and approved for
the use of biodiesel in blends up to 20% (B20)
provided that you comply with the requirements
outlined below. It is important that you understand
and comply with these requirements. Failure to
comply with Oil Change requirements for vehicles
operating on biodiesel blends up to B20 will result
in premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
Biodiesel is a fuel produced from renewable
resources typically derived from animal fat,
rapeseed oil (Rapeseed Methyl Ester (RME) base),
or soybean oil (Soy Methyl Ester (SME or SOME)
base). Biodiesel fuel has inherent limitations which
require that you understand and adhere to the
following requirements if you use blends of
biodiesel greater then 5% but not greater than
20% (B6-B20). There are no unique restrictions for
the use of B5. Use of blends greater than 20% is
not approved. Use of blends greater than 20% can
result in engine damage. Such damage is not
covered by the New Vehicle Limited Warranty. Fuel Quality — Must Comply With ASTM Standards
The quality of biodiesel fuel may vary widely. Only
fuel produced by a BQ9000 supplier to the
following specifications may be blended to meet
biodiesel blend (B6–B20) fuel meeting ASTM
specification D-7467:
Petrodiesel fuel meeting ASTM specification
D-975 and biodiesel fuel (B100) meeting ASTM
specification D-6751.
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if stored
properly, provides for protection against fuel
oxidation for up to six months.

23_DPF_OM_EN_USC_t.book Page 416

TECHNICAL SPECIFICATIONS417
Fuel Water Separation — Must Use
Mopar®/Cummins® Approved Fuel Filter
Elements
You must use Mopar®/Cummins® approved fuel
filter elements in both your engine mounted filter
and frame mounted filter.
Biodiesel fuel has a natural affinity to water and
water accelerates microbial growth. Your Mopar®/
Cummins® filtration system is designed to provide
adequate fuel water separation capabilities.
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for both
storage and operation. Precautions can be
necessary at low ambient temperatures, such as
storing the fuel in a heated building or a heated
storage tank, or using cold temperature additives.
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 maintained to the
following schedule:
Ram 3500/4500/5500 Chassis Cab —
12,500 Miles (20,000 km)*
(*unless otherwise notified with a oil service
message)
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 six 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 concentra -
tions of Biodiesel higher than 20%.
