10 THINGS TO KNOW BEFORE STARTING YOUR 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:
•The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Mobil Speedpass™, 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.
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

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.
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.
DOORS AND 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!
For personal security, and safety in the event of an
accident, lock the vehicle doors as you drive as well
as when you park and leave the vehicle.

3. To reassemble the transmitter case, join the two halves
of the case together. Install and tighten the screw until
snug. Make sure there is an even “gap” between the two
halves. Test transmitter operation.
SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors, liftgate, liftgate
flipper glass, and ignition for unauthorized operation.
When the alarm is activated, the system provides both
audible and visual signals. The horn will sound repeat-
edly for three minutes and the headlights and taillights
will flash for an additional 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 this16 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
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 pull the
door handle to exit the alarm will sound. If this occurs,
press the “Unlock” button on the remote keyless entry
transmitter to disarm the 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.
LIFTGATE
To open the liftgate, pull up (squeeze) on the handle and
lift. Manually unlocking the vehicle doors with the
plunger or a key in the lock cylinder will not unlock the
liftgate.
Liftgate Release
26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If your vehicle is so equipped, the window bag on the
crash side of the vehicle is triggered in moderate to
severe side collisions. In certain types of collisions, both
the front and side airbags may be triggered. But even in
collisions where the airbags work, you need the seat belts
to keep you in the right position for the airbags to protect
you properly.
Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag.
1. Children 12 years and under should always ride
buckled up in a rear seat.
Infants in rear facing child restraints shouldNEVERride
in the front seat of a vehicle with a passenger airbag. An
airbag deployment could cause severe injury or death to
infants in that position.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 “Child Restraint” 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.

•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•TheSide Impact SRS Side Curtain Airbagsare de-
signed to activate only in certain side or rollover
collisions. When the ORC (with side impact option)
detects a collision requiring the side curtain airbag to
inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the side curtain airbag. The inflating side cur-
tain airbag pushes the outside edge of the headliner
out of the way and covers the window. The airbag
inflates in about 30 milliseconds (about one quarter of
the time it takes to blink your eyes) with enough force
to injure you if you are not belted and seated properly,
or if items are positioned in the area where the sidecurtain airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about 3
12inches
(9 cm) thick when it is inflated.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.

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.
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
•
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 “convertible” child seats.
