DRIVING AND ALCOHOL
Drunken driving is one of the most frequent causes of acci-
dents.
Your driving ability can be seriously impaired with blood alcohol
levels far below the legal minimum. If you are drinking, don’t
drive. Ride with a designated non-drinking driver, call a cab, a
friend, or use public transportation.
WARNING!
Driving after drinking can lead to an accident. Your per-
ceptions are less sharp, your reflexes are slower, and your
judgment is impaired when you have been drinking.
Never drink and then drive.
This manual illustrates and describes the operation of features
and equipment that are either standard or optional on this
vehicle. This manual may also include a description of features
and equipment that are no longer available or were not ordered
on this vehicle. Please disregard any features and equipment
described in this manual that are not on this vehicle.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this vehi-
cle’s electronic system to provide immunity to radio frequency
signals. Mobile two-way radios and telephone equipment must
be installed properly by trained personnel. The following must
be observed during installation.
The positive power connection should be made directly to the
battery and fused as close to the battery as possible. The
negative power connection should be made to body sheet
metal adjacent to the negative battery connection. This con-
nection should not be fused.
Antennas for two-way radios should be mounted on the roof or
the rear area of the vehicle. Care should be used in mounting
antennas with magnet bases. Magnets may affect the accu-
racy or operation of the compass on vehicles so equipped. The antenna cable should be as short as practical and routed
away from the vehicle wiring when possible. Use only fully
shielded coaxial cable.
Carefully match the antenna and cable to the radio to ensure a
low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than nor-
mal may require special precautions.
All installations should be checked for possible interference
between the communications equipment and the vehicle’s
electronic systems.

A MESSAGE FROM CHRYSLER GROUP LLC
Chrysler Group LLC and Cumminswelcome you as a
Cummins turbocharged diesel-powered truck owner.
Your diesel truck will sound, feel, drive, and operate
differently from a gasoline-powered truck. It is important
that you read and understand this manual.
Almost 100% of the heavy duty trucks in the United
States and Canada are diesel-powered because of the fuel
economy, rugged durability, and high torque which per-
mits pulling heavy loads. Cummins engines power well
over half of these trucks. Now this same technology and
proven performance is yours in your truck equipped
with the Cummins turbocharged diesel engine.
You may find that some of the starting, operating, and
maintenance procedures are different. However, they are
simple to follow and careful adherence to them will
ensure that you take full advantage of the features of this
engine. NOTE:
Some aftermarket products may cause severe
engine/transmission and/or exhaust system damage.
Your vehicle’s Powertrain Control Systems can detect
and store information about vehicle modifications that
increase horsepower and torque output such as whether
or not performance-enhancing powertrain components,
commonly referred to as downloaders, power boxes, or
performance chips have been used.
This information cannot be erased and will stay in the
system’s memory even if the modification is removed.
This information can be retrieved by Chrysler Group
LLC, and service and repair facilities, when servicing
your vehicle. This information may be used to determine
if repair will be covered by New Vehicle Limited War-
ranty.
4 INTRODUCTION

There is a probability that the use of a “performance
chip” will prohibit the engine from starting. In this
instance, the vehicle will need to be serviced by a
authorized dealer in order to return the vehicle to it’s
factory settings.
