light will come on for 3 seconds immediately after the
ignition switch is turned on for a bulb check. Afterwards,
if the bulb remains on, this indicates a malfunction in the
electronics. If the bulb begins to flash immediately after
the ignition switch is turned on, this indicates that an
invalid key is being used to start the vehicle. Both of
these conditions will result in the engine being shut
down after 2 seconds of running. Keep in mind that a key
which has not been programmed is also considered an
invalid key even if it is cut to fit the ignition for that
vehicle.
If the SKIM indicator light comes on during normal
vehicle operation (it has been running for longer than 10
seconds) a fault has been detected in the electronics and
the vehicle should be serviced as soon as possible.
NOTE:
²The Sentry Key Immobilizer System is not compatiblewith remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
²Mobil SpeedpassŸ, additional Sentry Keys, or any
other transponder equipped components on the same
keychain will not cause a key-related (Transponder)
fault unless the additional part isphysically held
against the ignition keybeing used when starting the
vehicle. Also, cell phones, pagers, or other RF electron-
ics will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Important Note About Service
A four digit PIN number is needed to service the Sentry
Key Immobilizer System. This number can be obtained
from your authorized dealer. However, this number can
also be found on your customer invoice that you were
given upon receipt of your vehicle.

4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The SKIM indicator
light will stop flashing, turn on for 3 seconds; then turn
off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.
General Information
The Sentry Key Immobilizer System complies with FCC
rules part 15 and with RSS-210 of Industry Canada.
Operation is subject to the following two 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 undes-
ired operation.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This system monitors the vehicle doors, liftgate, liftgate
flipper glass, and ignition for unauthorized operation
and movement inside of the vehicle. When the alarm is
activated, the system provides both audible and visual
signals. The horn will sound repeatedly for three minutes
and the headlights and taillights will flash for an addi-
tional 15 minutes.
To Set the Alarm
The alarm will set when you use the remote keyless entry
transmitter to lock the doors and liftgate or when you use
the power door lock switch while the door is open. After
all the doors are locked and closed, a red light (located in
the instrument cluster) will flash rapidly for about 16
seconds to signal that the system is arming. During this
16 second pre-arm period, opening any door or the
liftgate will cancel the arming. If the system successfully
arms, the red light will flash at a slower rate to indicate
the alarm is set. A manual lock of the doors, either with
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

the door lock plunger located on the inside of the doors
or with the driver's door key lock cylinder, will not set
the alarm.
To Disarm the System
To disarm the system, use the remote keyless entry
transmitter. Also, using a valid sentry key and moving
the ignition switch to the ON/START position will
disarm the system. If something has triggered the system
in your absence, the horn will sound three times when
you unlock the doors. Check the vehicle for tampering.
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, once the
system is armed (after 16 seconds), when you move
inside of the vehicle or you pull the door handle to exit
the alarm will sound. If this occurs, press the ªUnlockº
button on the remote keyless entry transmitter to disarmthe system. The Security Alarm System will not disarm
with a manual unlock, either through the lock plunger
located on the inside of the door, or through a key in the
driver's door key cylinder.ILLUMINATED ENTRY
The interior lights come on when you open any door.
They will remain on for about 30 seconds after all doors
are closed then fade to off.
The lights also will fade to off if you turn on the ignition
after you close all the doors.
REMOTE KEYLESS ENTRY
This system allows you to lock or unlock the doors,
liftgate, or activate the panic alarm from distances up to
about 23 feet (7 meters) using a hand held transmitter.
The transmitter does not need to be pointed at the vehicle
to activate the system.

The vehicle can be started remotely up to a maximum of
two times. The vehicle is also allowed a maximum of one
failed start, where the remote start sequence was initiated
but cancelled before the engine begins to crank. After
either of these conditions, or if the Vehicle Theft Alarm is

DOOR LOCKS
Manual Door Locks
Use the manual door lock plunger to lock the doors from
inside the vehicle. If the plunger is down when the door
is closed, the door will lock. Therefore, make sure the
keys are not inside the vehicle before closing the door.
WARNING!
²For 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.
²When leaving the vehicle always remove the key
from the ignition lock, and lock your vehicle. Do
not leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause severe per-
sonal injuries and death.
Power Door Locks Ð If Equipped
A door lock switch is on each front door panel. Press this
switch to lock or unlock the doors.
26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Children that are not big enough to properly wear the
vehicle seat belt should be secured in the rear seat, in a
child restraint or belt-positioning booster seat. 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.
If a child from 1 to 12 years old must ride in the front
passenger seat because the vehicle is crowded, move the
seat as far back as possible, and use the proper child
restraint. See ªChild Restraintº in this section.
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. All occupants should use their lap and shoulder belts
properly.3. The driver and front passenger seats should be moved
back as far as practical to allow the front airbags room to
inflate.
4. Do not lean against the door or window, airbags will
inflate forcefully into the space between you and the
door.
5. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided under ªIf
You Need Assistanceº in Section 9 of this manual.

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time Ð 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.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner's Manual to ensure you have the right seat
for your child. Use the restraint that is correct for your
child:WARNING!
In a collision, an unrestrained child, even a tiny
baby, can become a missile inside the vehicle. The
force required to hold even an infant on your lap can
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child's
size.
Infants and Child Restraints
²
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year oldandweigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward-facing: infant
carriers and ªconvertibleº child seats.
