service 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.

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.

consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed.
NOTE:When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.
Customer Key Programming
You can program new keys to the system if you have two
valid keys by doing the following:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chimewill sound and the “Security Alarm System Indicator
Light” will begin to flash. Turn the ignition switch OFF
and remove the second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The “Security Alarm
System Indicator Light” will stop flashing, turn on for 3
seconds; then turn off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.
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.

WARNING!
The rear center lap/shoulder belt is equipped with a
lock-out feature to ensure that the rear seat back is in
the fully upright and locked position when occupied.
If the rear seat back is not fully upright and locked
and the rear center lap/shoulder belt can be pulled
out of the retractor, the vehicle should immediately
be taken to your dealer for service. Failure to follow
this warning could result in serious or fatal injury.
Adjustable Upper Shoulder Belt Anchorage
In the front seat positions, the shoulder belt anchorage
can be adjusted upward or downward to position the belt
away from your neck. Push in on the anchorage near
your outside shoulder and slide it up or down to reach
the position that serves you best.

The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult
will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the
“PAD Indicator Light” is not illuminated when an adult
is riding in the front passenger seat. If an adult occu-
pant’s weight is transferred to another part of the vehicle
(like the door or instrument panel), the weight sensors in
the seat may not properly classify the occupant. Objects
lodged under the seat or between the seat and the center
console can prevent the occupant’s weight from beingmeasured properly and may result in the occupant being
improperly classified. Ensure that the front passenger
seat back does not touch anything placed on the back seat
because this can also affect occupant classification. Also,
if you fold down the rear seat check to be sure it doesn’t
touch the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the “Airbag Warning
Light” (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The “Airbag Warning Light” is turned
on whenever there is fault that can affect the operation of
the airbag system. If there is a fault present in the OCS,
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The following requirements must be strictly adhered to:
•Do not modify the front passenger seat assembly or
components in any way.
•Do not modify the front seat center console or center
position seat in any way.
•Do not use prior or future model year seat covers not
designated for the specific model being repaired. Al-
ways use the correct seat cover specified for the
vehicle.
•Do not replace the seat cover with an aftermarket seat
cover.
•Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar.
•At no time should any supplemental restraint system
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by DaimlerChrysler/
Mopar.
WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag deployment in case of a frontal crash. This
could result in death or serious injury to the front
seat passenger if the vehicle is involved in an acci-
dent. A modified vehicle may not comply with re-
quired Federal Motor Vehicle Safety Standards
(FMVSS).

WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioner, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible. Also, have the Occupant Classification Sys-
tem serviced as well.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could cause it to fail when you
need it. You could be injured if the airbag system is 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 or vehicle body structure.
•Do not attempt to modify any part of your advanced airbag system. The airbag
may inflate accidentally or may not function properly if modifications are made.
Take your vehicle to an authorized dealer for any advanced airbag system
service. If your seat including your trim cover and cushion needs to be serviced
in any way (including removal or loosening/tightening of seat attachment bolts),
take the vehicle to your authorized dealer. Only manufacturer approved seat
accessories may be used. If it is necessary to modify an advanced airbag system
for persons with disabilities, contact your authorized dealer.
•Do not place or hang any items such as add-on video players on the right front
passenger seat back. The additional weight may cause the Occupant Classifi-
cation System to be unable to correctly classify the right front occupant. This
could allow the passenger frontal airbag to inflate when it is not desired.
•You need proper knee impact protection in a collision. Do not mount or locate
any aftermarket equipment on or behind the knee bolsters.
•It 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 an airbag system.

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 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 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 5-seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment, or near deployment,and up to a quarter second of high-speed deceleration
data during and/or after air bag deployment or near-
deployment. EDR data are ONLY recorded if an airbag
deploys, or nearly deploys, and are otherwise unavail-
able.
NOTE:
•A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.
•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
