2004 JEEP GRAND CHEROKEE ECU

NOTE:When lifting up on the release handle, the
seatback will release easier if you do not pull forward on
the seatback; only lift up on the release handle until the
seatback disengages, then fold the seat forward.To restore the 60/40 rear seat to the upright
position perform the following steps:
Raise the seatback and lock it into place. If interference
from the cargo area prevents the seatback from fully
locking, you will have difficulty returning the seat cush-
ion to its proper position. Remove the headrests from the
cushion panel storage position and reinstall into the rear
seat back.
WARNING!
Be certain that the seatback is securely locked into
position. If the seatback in not securely locked into
position the seat will not provide the proper stability
for child seats and/or passengers. An improperly
latched seat could cause serious injury.
Rotate the seat cushion rearward until it is latched into
place.

WARNING!
Before programming HomeLink to a garage door
opener or gate operator, make sure that people and
objects are out of the way of the device to prevent
potential harm or damage. When programming a
garage door opener, it is advised to park outside of
the garage. Do not use HomeLink with any garage
door opener that lacks safety stop and reverse fea-
tures as required by U.S. federal safety standards
(this includes any garage door opener model manu-
factured before April 1, 1982). A garage door that
cannot detect an object - signaling the door to stop
and reverse - does not meet current U.S. federal
safety standards. For more information, contact
HomeLink at: www.homelink.com or by calling:
1-800-355-3515.
Retain the original transmitter of the RF device you are
programming for use in other vehicles as well as for
future HomeLink programming. It is also suggested that
upon the sale of the vehicle, the programmed HomeLink
buttons be erased for security purposes. To erase the
programmed buttons, perform the procedure shown
below under9When Your Vehicle Is New9, or, for assis-
tance, contact HomeLink at:www.homelink.comor by
calling:1-800-355-3515.
When Your Vehicle Is New
Prior to programming HomeLink for the first time the
factory test codes must be erased. To erase HomeLink
memory, press and hold the two outer HomeLink buttons
(buttons one and three). The message CLEARING
CHANNELS will appear on the HomeLink display. After
approximately 20 seconds, the message CHANNELS
CLEARED will appear on the EVIC display. Do not hold
the buttons for longer than 30 seconds.

Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to9time-out9(or quit) after several seconds of
transmission - which may not be long enough for
HomeLink to pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed to9time-out9in the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using the9Program-
ming HomeLink9procedures (regardless of where you
live), replace step two with the following:
NOTE:If programming a garage door opener or gate
operator, it is advised to unplug the device during the
9cycling9process to prevent possible overheating.
Press and hold the HomeLink button while you press
and release - every two seconds ((cycle() your hand-heldtransmitter button until the radio signal has success-
fully been accepted by HomeLink. (The message
TRAINED will appear on the HomeLink display.)
Proceed with the remaining steps under9Programming
HomeLink9to complete.
Using HomeLink
To operate, simply press and release the programmed
HomeLink button. Activation will now occur for the
trained device (i.e. garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc.). For convenience, the hand-held transmitter of the
device may also be used at any time. In the event that
there are still programming difficulties or questions,
contact HomeLink at:www.homelink.comor1-800-355-
3515.

Sunshade Operation
The sunshade covering the glass in the panel will open
with the sunroof and must be closed manually. It can also
be opened and closed manually without activating the
sunroof. This will allow you to enjoy the warmth of the
sun during the winter months.WARNING!
In an accident, there is greater risk of being thrown
from a vehicle with an open sunroof. You could be
seriously injured or killed. Always fasten your seat
belt properly and be sure all passengers are properly
secured too.
Maintenance
Care should be taken in cleaning the inside of the glass.
Use only nonabrasive cleaners and a soft cloth.
WARNING!
Do not allow small children to operate the sunroof,
and never allow objects to project through the sun-
roof opening. Injury may result.

CAUTION!
Electrical Outlet Use With Engine Off
²Many accessories that can be plugged in draw
power from the vehicle's battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle's battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
²Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
²After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle's battery.
GLOVE COMPARTMENT
The glove compartment light will remain on if the glove
box door is not securely closed, causing an unnecessary
drain on the battery.
CUP HOLDERS
In the center console there are two cup holders for the
front seat passengers.

WARNING!
In an accident a cargo cover loose in the vehicle
could cause injury. It could fly around in a sudden
stop and strike someone in the vehicle. Do not store
the cargo cover on the cargo floor or in the passenger
compartment. Remove the cover from the vehicle
when taken from its mounting. Do not store in the
vehicle.
Cargo Tie-Down Hooks
The tie-downs located on cargo area floor should be used
to safely secure loads when vehicle is moving.

ROOF LUGGAGE RACK
External racks do not increase the total load carrying
capacity of the vehicle. Be sure that the total occupant
and luggage load inside the vehicle, plus the load on the
luggage rack, do not exceed the rated vehicle capacity.
This vehicle is not equipped with roof rack cross rails as
built, unless ordered as optional equipment. Cross rails
must be installed prior to carrying loads on the roof rack.
If not equipped, your authorized dealer can order and
install Mopartcross rails built specifically for this roof
rack system or a number of after market rails that are
tailored to your life-style or activities.CAUTION!
²To prevent damage to the roof of your vehicle, DO
NOT carry any loads on the roof rack without cross
rails installed. The load should be secured and
placed on top of the cross rails, not directly on the
roof. If it is necessary to place the load on the roof,
place a blanket or some other protection between the
load and the roof surface.
²To avoid damage to the roof rack and vehicle, do not
exceed the rated load capacity of your cross rail system
or the roof rack system maximum load capacity of 150
lbs (68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
²Long loads which extend over the windshield, such
as wood panels or surfboards, should be secured to
both the front and rear of the vehicle.
²Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward loads. This is espe-
cially true on large flat loads and may result in
damage to the cargo or your vehicle.
