ECU JEEP WRANGLER 2004 TJ / 2.G Owners Manual

Key-In-Ignition Reminder
Opening the driver's door when the key is in the ignition,
sounds a signal to remind you to remove the key.
CAUTION!
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
SENTRY KEY IMMOBILIZER SYSTEM Ð IF
EQUIPPED
The Sentry Key Immobilizer System (SKIS) prevents
unauthorized operation of the vehicle by disabling the
engine. The system will shut the engine down after 2
seconds of running if an invalid key is used to start the
vehicle. This system utilizes ignition keys which have an
electronic chip (transponder) embedded into them. Only
keys that have been programmed to the vehicle can be
used to start and operate the vehicle for longer than the
2 second validation time period.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automaticregardless of whether or not the vehicle is locked or
unlocked. During normal operation, the SKIS indicator
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 SKIS 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:
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.
12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
²For personal security reasons and safety in 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.
OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems. These include the front
and rear seat belts for the driver and all passengers, and
front airbags for both the driver and front passenger. If
you will be carrying children too small for adult-size
belts, your seat belts can also be used to hold infant and
child restraint systems.
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly to keep you and your passengers as safe as
possible.
WARNING!
In a collision, you and your passengers can suffer
injuries, including fatalities, if you are not properly
buckled up. You can strike the interior of your
vehicle or other passengers, or you can be thrown out
of the vehicle. Always be sure you and others in your
vehicle are buckled up properly.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbags inflate in moderate to high speed impacts. Along
with the seat belts, front airbags work with the instru-
ment panel knee bolsters to provide improved protection
for the driver and front passenger.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions. 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 old and under should always ride
buckled up in a rear seat.
Infants in rear-facing child restraints (designed for chil-
dren up to 20 lbs (9 kg) and at least one year old) should
NEVERride in the front seat of a vehicle with a passen-
ger front airbag, unless the airbag is turned off. An airbag
deployment can cause severe injury or death to infants in
this position.Children that are not big enough to properly wear the
vehicle seat belt (Refer to ªChild Restraintº in this
section.) 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. Refer to 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.

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
Airbag Warning Light
You will want to have the airbags ready to inflate for your
protection in an collision. While the airbag system is
designed to be maintenance free, if any of the following
occurs, have an authorized dealer service the system
immediately.
²The ªAirbag Warning Lightº does not come on or
flickers during the 6 to 8 seconds when the ignition
switch is first turned on.
²The ªAirbag Warning Lightº remains on or flickers
after the 6 to 8 second interval.
²The ªAirbag Warning Lightº flickers or comes on and
remains on while driving.
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.

Here are some tips on getting the most out of your child
restraint:
²Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. The manufacturer also recommends that
you make sure that you can install the child restraint in
the vehicle where you will use it before you buy it.
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.
²The passenger seat belts are equipped with cinching
latch plates designed to keep the lap portion or lap belt
tight around the child restraint so that it is not
necessary to use a locking clip. Pull up on the shoulder
portion of the lap/shoulder belt, or on the free end of
the lap belt to tighten the belt. The cinching latch plate
will keep the belt tight, however, any seat belt system
will loosen with time, so check the belt occasionally
and pull it tight if necessary.
²In the rear seat, you may have trouble tightening the
lap belt or 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.
²If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
²Buckle the child into the seat according to the child
restraint manufacturer's instructions.
²When your child restraint is not in use, secure it 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.

LATCH Ð Child Seat Anchorage System (Lower
Anchors and Tether for CH ildren)
Your vehicle's front passenger and two rear outboard (if
equipped) seating positions are 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.The two rear outboard seating positions have lower
anchorages that are capable of accommodating LATCH-
compatible child seats having flexible, webbing-mounted
lower attachments. Child seats with fixed lower attach-
ments must be installed in the outboard positions only.
Regardless of the specific type of lower attachment,
NEVERinstall LATCH-compatible child seats such that
two seats share a common lower anchorage. If installing
child seats in adjacent rear-seating positions or if your
child restraints are not LATCH-compatible, install the
restraints using the vehicle's seat belts.
Installing the LATCH-Compatible Child Restraint
System
We urge that you carefully follow the directions of the
manufacturer when installing your child restraint. Not all
child restraint systems will be installed as described here.
Again, carefully follow the installation instructions that
were provided with the child restraint system.

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 cannot 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:
Route the tether strap over the front passenger seat back
and attach the hook to the tether anchor located on the
back of the seat. For the rear outboard seating positions,
route the tether over the rear seat and attach to the rear
floor tether anchors. If the Add-A-TrunkŸ option is
present in the vehicle, the lid should be opened and
positioned against the back of the rear seat prior to
attaching and adjusting the strap.

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.
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 seated upright in the seat.
²The lap belt 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.

38 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²If the shoulder belt contacts the child's 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.
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.

4. Secure the seat with the strap. Wrap strap around
sport bar, and put one end of the strap through loop of
the other end. Pull to tighten strap around sport bar.
Place the opposite loop around hook of seat. Route the
strap so that it is between the plates of the seat to
eliminate slack and increase tension, as shown.
5. When completed, return seat to it's normal position.Removing the Rear Seat
WARNING!
²It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision people
riding in these areas are more likely to be seri-
ously injured or killed.
²Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts.
²Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
