If the bulb begins to flash after the bulb check, this
indicates that an invalid key has been used to start the
vehicle. Both of these conditions will result in the engine
being shut off after two (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 lock cylinder for that vehicle.
If the Theft Alarm/Immobilizer Light comes on during
normal vehicle operation (vehicle 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:
²
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.
²Exxon/Mobil Speed Pass,Ÿ additional Sentry Keys, or
any other transponder equipped components on thesame keychain willnot
cause a key-related (tran-
sponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used
when starting the vehicle. Cell phones, pagers, or
other RF electronics will not cause interference with
this system.
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 can
not 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.

WARNING!
²For 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.
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
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
chime will sound if the key is in the LOCK or ACC
position and a door is open, as a reminder to remove the
key.

Here are some simple steps you can take to minimize
the risk of harm from a deploying airbag.
1. Children 12 years old and under should ride buckled
up in the rear seat. Infants in rear-facing child restraints
shouldNEVERride in the front seat of a vehicle with a
passenger front 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 (see section on ªChild Restraintº) 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.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 the section on ªChild Restraintº.
2. You should read the instructions provided with your
child restraint to make sure that you are using it properly.
3. All occupants should use their seat belts properly.
4. The driver and front passenger seats should be moved
back as far as practical to allow the airbags time to inflate.
5. If your vehicle has left and right side curtain airbags,
do not lean against the door, airbags will inflate forcefully
into the space between you and the door.

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.
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
could 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.
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:

²The restraint must be appropriate for your child's
weight and height. Check the label on the restraint for
weight and height limits.
²Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
²Buckle the child into the seat according to the child
restraint manufacturer's directions.
²When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seat backs
and cause serious personal injury.
NOTE:For additional information refer to
www.seatcheck.org or call 1±866±SEATCHECK.
Older Children and Child Restraints
Children who weigh more than 20 lbs (9 kg) and who are
older than one year can ride forward-facing in the
vehicle. Forward-facing child seats and convertible child
seats used in the forward-facing direction are for children
who weigh 20 to 40 lbs (9 to 18 kg) and who are older
than one year. These child seats are also held in the
vehicle by the lap/shoulder belt or the LATCH child
restraint anchorage system. (See the LATCH Ð Child
Seat Anchorage System Section.)
The belt-positioning booster seat is for children weighing
more than 40 lbs (18 kg), but who are still too small to fit
the vehicle's seat belts properly. If the child cannot sit
with knees bent over the vehicle's seat cushion while the
child's back is against the seat back, they should use a
belt-positioning booster seat. The child and belt-
positioning booster seat are held in the vehicle by the
lap/shoulder belt.

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.
²If 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.
LATCH Ð Child Seat Anchorage System (Lower
Anchors and Tether for CH ildren)
Your vehicle's rear seat is equipped with the child
restraint anchorage system called LATCH. The LATCH
system provides for the installation of the child restraint
without using the vehicle's seat belts, instead securing
the child restraint using lower anchorages and upper
tether straps from the child restraint to the vehicle
structure.
LATCH-compatible child restraint systems are now avail-
able. However, because the lower anchorages are to be
introduced over a period of years, child restraint systems
having attachments for those anchorages will continue to
also have features for installation using the vehicle's seat
belts. Child restraints having tether straps and hooks for
connection to the top tether anchorages have been avail-
able for some time. For some older child restraints, many
child restraint manufacturers offer add-on tether strap
kits or retro-fit kits. You are urged to take advantage of all
the available attachments provided with your child re-
straint in any vehicle.

In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path opening
on the restraint. Disconnect the latch plate from the
buckle and twist the short buckle-end belt several times
to shorten it. Insert the latch plate into the buckle with the
release button facing out.
If the belt still can't be tightened, or if by pulling and
pushing on the restraint loosens the belt, you may need
to do something more. Disconnect the latch plate from
the buckle, turn the buckle around, and insert the latch
plate into the buckle again. If you still can't make the
child restraint secure, try a different seating position.
To attach a child restraint tether strap:
1. Rotate the cover over the anchor directly behind the
seat where you are placing the child restraint.2. Route the tether strap to provide the most direct path
for the strap between the anchor and the child seat. If
your vehicle is equipped with adjustable rear head
restraints, raise the head restraint and, where possible,
route the tether strap under the head restraint and
between the two posts. If not possible, lower the head
restraint and pass the tether strap around the outboard
side of the head restraint.

3. Attach the tether strap hook (A) of the child restraint to
the anchor (B) and remove slack in the tether strap
according to the child restraint manufacturer's instruc-
tions.
WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
