high JEEP WRANGLER 2008 JK / 3.G Owners Manual

NOTE:After you read the manual, it should be stored in
the vehicle for convenient reference and remain with the
vehicle when sold so that the new owner will be aware of
all safety warnings.
When it comes to service, remember that your authorized
dealer knows your vehicle best, has the factory-trained
technicians and genuine MOPAR parts, and is inter-
ested in your satisfaction.
ROLLOVER WARNING
Utility vehicles have a significantly higher rollover rate
than other types of vehicles. This vehicle has a higher
ground clearance, higher center of gravity, and narrower
track than many passenger cars. It is capable of perform-
ing better in a wide variety of off-road applications.
Driven in an unsafe manner, all vehicles can be caused to
go out of control. Because of the higher center of gravity
and the narrower track, if this vehicle is out of control it
may roll over when some other vehicles may not. 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 belts subjects 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.
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.

Do not attempt sharp turns or abrupt maneuvers or other
unsafe driving actions that can cause loss of vehicle
control. Failure to operate this vehicle safely may result
in an accident, rollover of the vehicle and serious injury
or death. Because of its open-body construction, your
vehicle offers less protection than closed vehicles in the
event of an accident.Failure to use driver and passenger seat belts
provided
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 two
million annually. In a rollover crash, an unbelted person
is significantly more likely to die than a person wearing
a seal belt. Always buckle up.

6 INTRODUCTION

WARNING!
A belt that is buckled into the wrong buckle will not
protect you properly. The lap portion could ride too high
on your body, possibly causing internal injuries. Always
buckle your belt into the buckle nearest you.
A belt that is loose will not protect you as well. In a
sudden stop you could move too far forward, increasing
the possibility of injury. Wear your seat belt snugly.
A belt that is worn under your arm is very dangerous.
Your body could strike the inside surfaces of the vehicle
in a collision, increasing head and neck injury. A belt
worn under the arm can cause internal injuries. Ribs
aren’t as strong as shoulder bones. Wear the belt over
your shoulder so that the strongest bones will take the
force in a collision.
A shoulder belt placed behind will not protect you from
injury during a collision. You are more likely to hit your
head in a collision if you do not wear your shoulder belt.
The lap and shoulder belt are meant to be used together.
4. Position the lap belt across your thighs, below your
abdomen. To remove slack in the lap belt portion, pull up
on the shoulder belt. To loosen the lap belt if it is too tight,
tilt the latch plate and pull on the lap belt. A snug belt
reduces the risk of sliding under the belt in a collision.
NOTE:The Seat Belt Indicator Light will remain on
until the driver’s seat belt is buckled.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
A lap belt worn too high can increase the risk of
internal injury in a collision. The belt forces won’t be
at the strong hip and pelvic bones, but across your
abdomen. Always wear the lap belt as low as pos-
sible and keep it snug.
A twisted belt cannot do its job as well. In a collision
it could even cut into you. Be sure the belt is straight.
If you cannot straighten a belt in your vehicle, take it
to your authorized dealer and have it fixed.
5. Position the shoulder belt on your chest so that it is
comfortable and not resting on your neck. The retractor
will withdraw any slack in the belt.

WARNING!
Position the shoulder belt height adjusters so that the
belt rests across the middle of your shoulder. Failure
to adjust the safety belt properly could reduce the
effectiveness of the seat belt and increase the risk of
injury in a collision.
As a guide, if you are shorter than average, you will
prefer a lower position, and if you are taller than average,
you’ll prefer a higher position. When you release the
anchorage, try to move it up or down to make sure that
it is locked in position.
Seat Belt Pretensioners
The driver and front passenger seat belts are equipped
with a pretensioning device that is designed to remove
any slack from the seat belt systems in the event of a
collision. This device improves the performance of the
seat belt by assuring that the belt is tight around the
occupant early in a collision. Pretensioners work for all
size occupants, including those in child restraints.
NOTE: These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Control (ORC) Module. Like the front airbags, the
pretensioners are a single use item. After a collision that
is severe enough to deploy the airbags and pretensioners,
they must be replaced.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Enhanced Warning System (BeltAlert) can be reac-
tivated by repeating this procedure.
NOTE:Although the Enhanced Warning System
(BeltAlert) has been deactivated, the Seat Belt Warning
Light will continue to illuminate while the driver’s seat
belt remains unfastened.
Seat Belts And Pregnant Women
We recommend that pregnant women use seat belts
throughout their pregnancy. Keeping the mother safe is
the best way to keep the baby safe.
Pregnant women should wear the lap part of the belt
across the thighs and as snug across the hips as possible.
Keep the belt low so that it does not come across the
abdomen. That way the strong bones of the hips will take
the force if there is a collision.
Seat Belt Extender
If a seat belt is too short, even when fully extended and
when the adjustable upper shoulder belt anchorage (if
equipped) is in its lowest position, your authorized
dealer can provide you with a seat belt extender. This
extender should be used only if the existing belt is not
long enough. When it is not required, remove the ex-
tender and store it.
WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the seat belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and stow the seat belt extender
when not needed.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•TheSide Impact (SRS) Seat-Mounted Side Airbags
(If Equipped) are designed to activate only in certain
side collisions.
The ORC determines if a side collision is severe
enough to require the side airbags to inflate.
The ORC monitors the readiness of the electronic parts of
the system whenever the ignition switch is in the START
or ON positions. These include all of the items previously
mentioned.
In moderate to severe side collisions, the side airbag
inflator on the crash side of the vehicle is triggered,
releasing a quantity of nontoxic gas. The inflating side
airbag exits through the seat seam into the space between
the occupant and the door. The side airbag moves at a
very high speed and with such a high force, that it could
injure you if you are not seated properly, or if items are
positioned in the area where the side airbag inflates. This
especially applies to children.•The Knee Impact Bolsters help protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
If A Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Control (ORC) Module detects a
moderate-to-severe frontal collision, to help restrain the
driver and front passenger, and then to immediately
deflate.
NOTE: A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front

NOTE:Perchlorate Material – special handling may

perchlorate.
Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Does not come on during the six to eight seconds after
the ignition switch is first turned on.
•Remains on after the six to eight second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder prior to the moment of airbag deployment, and up to a
quarter-second of high-speed deceleration data during
and/or after airbag deployment or near-deployment.
EDR data are ONLY recorded if an airbag deploys, or
nearly deploys, and are otherwise unavailable.
NOTE:
•Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by DaimlerChrysler Corporation and others to learn
more about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
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.
•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). “Convertible” child seats often
have a higher weight limit in the rearward-facing
direction than infant carriers do, so they can be used
rearward-facing by children who weigh more than 20
lbs (9 kg) but are less than one year old. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt or the LATCH child restraint anchorage
system (Refer to LATCH — Child Seat Anchorage
System in this section.)
•Rearward-facing child seats must NEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your vehicle.
Drive moderately during the first 300 mi (500 km). After
the initial 60 mi (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 detri-
mental 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. For
the recommended viscosity and quality grades, refer to
“Maintenance Procedures” 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.
