4 INTRODUCTION

The9Security Light9, located in the instrument cluster,
will illuminate for about 2 seconds when the ignition
switch is first turned to the ON position. If the vehicle
electronics do not receive a valid signal from the ignition
key, the9Security Light9will flash continuously to signal
that the vehicle has been immobilized. If the9Security
Light9remains on during vehicle operation, it indicates a
fault in the system electronics. If this option was ordered,
all of the keys provided with your new vehicle have been
programmed to the vehicle electronics.
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 number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed 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.
NOTE:When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.

Customer Key Programming
You can program new keys to the system if you have two
valid keys by doing the following:
1. Insert the first valid key into the ignition and turn the
ignition to the ON position for at least 3 seconds but no
longer than 15 seconds. Turn the ignition back to the OFF
position and remove the first key.
2. Insert the second valid key and switch the ignition to
the ON position within 15 seconds. After 10 seconds the
9Security Light9will begin to flash. Turn the ignition back
to the OFF position and remove the second key.
3. Insert a blank Sentry Key into the ignition and switch
the ignition to the ON position within 60 seconds of
having removed the second key. After 10 seconds the
9Security Light9will stop flashing, then turn on for 3
seconds; then turn off.The new Sentry Key has been programmed. Repeat this
process to program up to an additional 6 keys. A maxi-
mum of 8 keys can be programmed to the system,
including the original keys provided with the vehicle.

2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
Transmitter Battery Service
The recommended replacement battery is a 3V lithium
2016 cell. This transmitter requires two batteries.NOTE:Do not touch the battery terminals that are on
the back housing or the printed circuit board.
1. With transmitter buttons facing down, use a flat blade
or dime to pry the two halves of the transmitter apart.
Make sure not to damage the rubber gasket during
removal.
2. Remove and replace the batteries. Be careful not to
disturb the metal terminal near the batteries. Install the
batteries with the positive terminal up, reference the note
9+ SIDE UP9on the inside of the bottom half of the
transmitter case. Avoid touching the new batteries with
your fingers. Skin oils may cause battery deterioration. If
you touch a battery, clean it with rubbing alcohol.
3. To reassemble the transmitter case snap the two halves
together. Make sure there is an even gap between the two
halves. Test transmitter operation.
28 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

SECURITY ALARM SYSTEM Ð 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,
turn the key in the driver's door lock cylinder, 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.
NOTE:If the SECURITY light stays on continuously
during vehicle operation, have the system checked by
your dealer.

Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back should use the lap/shoulder belt in a rear seat.
²Make sure that the child is upright in the seat.
²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
NEW ENGINE BREAK-IN
Your Cummins 24 Valve Turbo Diesel engine does not
require a normal break-in period due to its construction.
Normal operation is allowed, provided the following
recommendations are followed:
NOTE:Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
²Warm up the engine before placing it under load.
²Do not operate the engine at idle for prolonged
periods.
²Use the appropriate transmission gear to prevent
engine lugging.
²Observe vehicle oil pressure and temperature indica-
tors.
