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 that has not been programmed is consid-
ered 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). THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

automatically cancel after 3 minutes or if the vehicle is
started and exceeds 15 mph. During the Panic Mode, the
door locks and remote keyless entry systems will func-
tion normally. Panic mode will not disarm the security
system on vehicles so equipped.
General Information
This device complies with part 15 of FCC rules and with
RS-210 of Industry Canada. Operation is subject to the
following conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference that may be
received including interference that may cause undesired
operation. NOTE: Changes or modifications not expressly ap-
proved by the party responsible for compliance could
void the user’s authority to operate the equipment.
If your Keyless Entry Transmitter fails to operate from a
normal distance, check for these two conditions.
1. Weak batteries in transmitter. The expected life of the
batteries is from one to two years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 23

WARNING!• For personal security and safety in the event of an
accident, lock the vehicle doors when you drive as
well as when you park and leave the vehicle.
• 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.
Power Door Locks — If Equipped
A power door lock switch is on each front door trim
panel. Use this switch to lock or unlock the doors. If you press the power door lock switch while the key is
in the ignition, and any front door is open, the power
locks will not operate. This prevents you from acciden-
tally locking your keys in the vehicle. Removing the key
or closing the door will allow the locks to operate. A Power Door Lock Switch Location THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 27

airbag unless the airbag is turned off (Standard Cab
Vehicles Only). An airbag deployment can cause se-
vere injury or death to infants in that position. See the
Passenger Airbag On/Off Switch (If Equipped) sec-
tion.
• If your vehicle does not have a rear seat, see the
Passenger Airbag On/Off Switch (If Equipped) sec-
tion.
• Children that are not big enough to properly wear the
vehicle seat belt (see section on Child Restraints)
should be secured in the rear seat in child restraints or
belt-positioning booster seats. Older children who do
not use child restraints or belt-positioning booster
seats should ride properly buckled up in the rear seat.
Never allow children to slide the shoulder belt behind
them or under their arm.
• All occupants should use their seat belts properly. • The driver and front passenger seats should be moved
back as far as practical to allow the airbag room to
inflate.
WARNING!• Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
• Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time — babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59
