2007 JEEP GRAND CHEROKEE service

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, roll over of the vehicle, and severe or fatal
injury. Drive carefully.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 seat belt. Always buckle up.
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.

12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 SKIM 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:
•The Sentry Key Immobilizer System is not compatiblewith 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.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 cannot
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.
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 chime
will sound and the SKIM indicator light will begin to
flash. Turn the ignition switch OFF and remove the
second key.

3. Allow the belt to retract. As the belt retracts, you will
hear a clicking sound. This indicates the safety belt is
now in the automatic locking mode.
How to Disengage The Automatic Locking Mode
Disconnect the combination lap/shoulder belt and allow
it to retract completely to disengage the automatic lock-
ing mode and activate the vehicle sensitive (emergency)
locking mode.
Energy Management Feature
This vehicle has a safety belt system with an energy
management feature in the front seating positions to help
further reduce the risk of injury in the event of a head-on
collision.
This safety belt system has a retractor assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.
WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly “automatic locking re-
tractor” feature or any other seat belt function is
not working properly when checked according to
the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.
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.
