A MESSAGE FROM DAIMLERCHRYSLER
CORPORATION
DaimlerChrysler Corporation and Cummins welcome
you as a new Dodge Ram Cummins Turbo Diesel-
powered truck owner.
Almost 100% of the heavy duty trucks in the United
States are diesel powered because of the fuel economy,
rugged durability, and high torque which permits pulling
heavy loads. Cummins engines power well over half of
these trucks. Now this same technology and proven
performance is yours in your new Dodge Ram truck
equipped with the Cummins 5.9 liter, Turbocharged,
Charge Air Cooled, Diesel engine.
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. 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.
Thank you for choosing the Dodge Ram truck with
Cummins Turbo Diesel power.

NOTE:If you try to remove the key before you place the
lever in PARK, the key may become trapped temporarily
in the ignition cylinder. If this occurs, rotate the key to the
right slightly, then remove the key as described. If a
malfunction occurs, the system will trap the key in the
ignition cylinder to warn you that this safety feature is
inoperable. The engine can be started and stopped but
the key cannot be removed until you obtain service.
NOTE: The power window switches, radio, power
sunroof (if equipped), and power outlets will remain
active for 10 minutes after the ignition switch is turned
off. Opening either front door will cancel this feature.WARNING!
Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don’t leave the keys in
the ignition. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove key from the ignition and lock all doors
when leaving the vehicle unattended.

STEERING WHEEL LOCK — IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock. This lock prevents steering the vehicle with-
out the ignition key. If the steering wheel is moved no
more than 1/2 turn in either direction and the key is not
in the ignition switch, the steering wheel will lock.
If You Wish To Manually Lock The Steering
Wheel:
With the engine running, turn the steering wheel upside
down, turn off the engine and remove the key. Turn the
steering wheel slightly in either direction until the lock
engages.
To Release The Steering Wheel Lock:
Insert the key in the ignition switch and start the engine.
If the key is difficult to turn, move the wheel slightly to
the right or left to disengage the lock.
NOTE: If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON positions, and the
brake pedal is depressed.
SENTRY KEY — IF EQUIPPED
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys, which have an embedded
electronic chip (transponder), to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate

the vehicle. The system will shut the engine off in two (2)
seconds if someone uses an invalid key to start the
engine.
NOTE: A key, which has not been programmed, is also
considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Alarm Indicator Light will
turn on for three (3) seconds for a bulb check. If the light
remains on after the bulb check, it indicates that there is
a problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-
viced as soon as possible.
Replacement Keys
NOTE:
Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it cannot
be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four digit PIN. This number is required for dealer
replacement of keys. Duplication of keys may be per-
formed at an authorized dealer or by using the Customer
Key Programming procedure. This procedure consists of
programming a blank key to the vehicle electronics. A
blank key is one which has never been programmed and
needs to be cut.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

General Information
The Sentry Key system complies with FCC rules part 15
and with RSS-210 of Industry Canada. Operation is
subject to the following conditions:
•This device may not cause harmful interference.
•This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors and ignition for
unauthorized operation. When the alarm is activated, the
system provides both audible and visual signals. For the
first 3 minutes the horn will sound and the headlights
and security telltale will flash repeatedly. For an addi-
tional 15 minutes only the headlights and security telltale
will flash. The engine will run only if a valid Sentry Key
is used to start the vehicle. Use of the Sentry Key will
disable the alarm.
Rearming of the System:
The security system will rearm itself after the 15 addi-
tional minutes of headlights and security telltale flashing,
if the system has not been disabled. If the condition
which initiated the alarm is still present, the system will
ignore that condition and monitor the remaining doors
and ignition.
To Set the Alarm:
The alarm will set when you use the power door locks, or
use the Keyless Entry transmitter to lock the doors. After
all the doors are locked and closed the SECURITY light in
the instrument cluster will flash rapidly to signal that the
system is arming. The security light in the instrument
panel cluster will flash rapidly for about 16 seconds to
indicate that the alarm is being set. After the alarm is set,
the security light will flash at a slower rate to indicate
that the system is armed.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:If the SECURITY light stays on continuously
during vehicle operation, have the system checked by
your dealer.
To Disarm the System:
Use the Keyless Entry transmitter to unlock the door. If
something has triggered the system in your absence, the
horn will sound three times when you unlock the doors
and the security lamp will flash for 30 seconds. Check the
vehicle for tampering.
The Security system will also disarm, if the vehicle is
started with a programmed Sentry Key. If an unpro-
grammed Sentry Key is used to start a vehicle, the engine
will run for 2 seconds and then the security alarm will be
initiated. To exit alarming mode, press the transmitter
Unlock button, or start the vehicle with a programmed
Sentry Key.
The Security Alarm System is designed to protect your
vehicle; however, you can create conditions where the system will arm unexpectedly. If you remain in the
vehicle and lock the doors with the transmitter, the alarm
will sound when you pull the door handle to exit. The
door will be locked but the Security Alarm will not arm.ILLUMINATED ENTRY SYSTEM — IF EQUIPPED
The courtesy lights will turn on when you use the keyless
entry transmitter or open the doors. This feature is only
available if you have Remote Keyless Entry.
The lights will fade to off after about 30 seconds or they
will immediately fade to off once the ignition switch is
turned on.
NOTE:
•The front courtesy overhead console, door courtesy
lights do not turn on if the dimmer control is in the
interior lights ON position (extreme top position).
•The illuminated entry system will not operate if the
dimmer control is in the “defeat” position (extreme
downward position).
