engine JEEP WRANGLER 2007 JK / 3.G Owners Manual

Failure to use driver and passenger seat beltsprovided
is a major cause of severe or fatal injury. In fact, the U.S.
government notes that the universal use of existing seat
belts could cut the highway death toll by 10,000 or more
each year, and could reduce disabling injuries by 2
million annually. In a roll over crash, an unbelted person
is significantly more likely to die than a person wearing
a seal belt. Always buckle up.
Although your vehicle may be equipped with a soft top
or optional hard top to give the occupants protection
from the weather, these tops do not offer structural
protection in the event of an accident and do not change
the open-body characteristic of the vehicle. Even though
your vehicle has a sport bar and side bars for some extra
protection, it is a truly open vehicle-there is no structural
integrated top and it has low sides and a folding wind-
shield. Many of these vehicles do not have fully enclosed
hard doors.Operating this vehicle at excessive speeds or while
intoxicated may result in loss of control, collision with
other vehicles or objects, going off the road, or overturn-
ing, any of which may lead to serious injury or death.
Also,failure to use standard seat beltssubjects the
driver and passengers to a greater risk of being thrown
out of an open-body vehicle than out of a closed vehicle
in an accident which can result in injury or death.
This manual has been prepared with the assistance of
service and engineering specialists to acquaint you with
the operation and maintenance of your new vehicle. It is
supplemented by a Warranty Information Booklet and
various customer oriented documents. You are urged to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.

WARNING!
Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal, or the gear selector
lever. Do not leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
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.
STEERING WHEEL LOCK — IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock (manual transmission only). This lock pre-
vents steering the vehicle without the ignition key. If the
steering wheel is moved a half turn in either direction
and the key is not in the ignition, the steering wheel will
lock.
To Manually Lock the Steering Wheel
With the engine running, rotate the steering wheel 1/2
revolution from straight ahead position, turn off the
engine and remove the key. Rotate the steering wheel
slightly in both directions until the lock engages.

To Release the Steering Wheel Lock
Insert the key in the ignition and turn the wheel slightly
to the right or left to disengage the lock.
NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIM) 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 automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the “Security Alarm
System 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 “Security Alarm System Indicator Light” comes on
during normal vehicle operation (it has been running for

The “Flash Lights On Lock/Unlock” feature can be
reactivated by repeating this procedure.
Programming Additional Transmitters
Vehicles will be shipped from the assembly plants with
two key fob transmitters programmed only for that
vehicle. A total of eight fobs can be programmed for your
vehicle. Additional fobs can be programmed to your
vehicle through the use of a currently programmed fob.
NOTE:When entering program mode using that fob, all
other programmed fobs will be erased and you will have
to reprogram them for your vehicle.
Use the Following procedure to program additional key
fobs if the vehicle is not equipped with Sentry Key:
1. Enter your vehicle and close all doors.
2. Fasten your seat belt (Fastening the seatbelt will cancel
any chiming that may confuse you during this program-
ming procedure).3. Place the key into the ignition.
4. Turn the ignition to the ON position (Do not start the
engine).
5. Press and hold the “Unlock” button on the key fob.
6. After holding the “Unlock” button for four seconds,
also press the PANIC button within 6 seconds.
7. When a single chime is heard release both buttons. The
chime is an indication that you have successfully entered
program mode. All fobs that are to be programmed must
be done so within 60 seconds of when the chime was
heard.
8. Using the fob to be programmed, press and release
both the “Lock” and “Unlock” buttons, simultaneously.
9. A single chime will be heard.
10. Within four seconds of hearing the chime, press and
release the “Unlock” button on the fob.

Enhanced Seat Belt Use Reminder System
(BeltAlert)
If the driver or front passenger seat belt has not been
buckled within 60 seconds of starting the vehicle and if
the vehicle speed is greater than 5 mph (8 km/h), the
Enhanced Warning System (BeltAlert) will alert the
driver to buckle their seat belt. The driver should also
instruct all other occupants to buckle their seat belts.
Once the warning is triggered, the Enhanced Warning
System (BeltAlert) will continue to chime and flash the
Seat Belt Warning Light for 96 seconds or until the driver
or front passenger seat belt is buckled.
The Enhanced Warning System (BeltAlert) will be reacti-
vated if the driver or front passenger seat belt is unbuck-
led for more than 10 seconds and the vehicle speed is
greater than 5 mph (8 km/h).The Enhanced Warning System (BeltAlert) can be en-
abled or disabled by your authorized dealer or by
following these steps:
NOTE:The following steps must occur within the first
60 seconds of the ignition switch being turned to the ON
or START position. The manufacturer does not recom-
mend deactivating the Enhanced Warning System
(BeltAlert).
1. Turn the ignition switch to the OFF position, and
buckle the driver or front passenger seat belt.
2. Turn the ignition key to the ACCESSORY/RUN posi-
tion (engine does not need to be running), and wait for
the Seat Belt Warning Light to turn off.
3. Within 60 seconds of starting the vehicle, unbuckle
and then re-buckle the driver or front passenger seat belt
at least three times within 10 seconds, ending with the
seat belt buckled.

Child Restraint
Everyone in your vehicle needs to be buckled up at all
times — 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 correct seat
for your child. Use the restraint that is correct for your
child.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
