2004 JEEP GRAND CHEROKEE Owners Manual

NOTE:To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass. Refer to Variance Map.
To Put Into a Calibration Mode
Turn on the ignition and set the display to ªCompass/
Temperature.º Press and hold the RESET button to
change the display between VAR (compass variance) and
CAL (compass calibration) modes. When the CAL sym-
bol is displayed complete three 360 degree turns in an
area free from large metal objects or power lines. The
CAL symbol will turn off and the compass will function
normally.
Compass Varianceis the difference between magnetic
north and geographic north. In some areas of the country,
the difference between magnetic and geographic north is
great enough to cause the compass to give false readings.
If this occurs, the compass variance must be set according
to the Compass Variance Map.

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.

Programming HomeLink
NOTE:It is recommended that a new battery be placed
in the hand-held transmitter of the device being pro-
grammed to HomeLink for quicker training and accurate
transmission of the radio frequency signal.
WARNING!
Vehicle exhaust contains carbon monoxide, a danger-
ous gas. Do not run the vehicle's engine while
programming HomeLink. Exhaust gas can cause se-
rious injury or death.
WARNING!
Your motorized door or gate will open and close
while you are programming HomeLink. Do not
program HomeLink if people or pets are in the path
of the door or gate. A moving door or gate can cause
serious injury or death to people and pets or damage
to objects.
1. Position the end of your hand-held transmitter 1-3
inches (5-14 cm) away from the lower left corner of the

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.

POWER SUNROOF Ð IF EQUIPPED
The sunroof is electrically operated from a switch located
in the overhead console. To operate the sunroof, the
ignition switch must be in the ON or ACC position. The
sunroof has ªManualº and ªExpress Openº modes of
operation when opening.
Express Open Mode
To open the sunroof in the Express Open mode, press the
switch rearward for less than one second. This causes the
sunroof glass to automatically retract and stop at the full
open position. This glass position provides the largest
possible opening while minimizing low-speed wind buf-
feting. If wind buffeting does occur, adjusting the sunroof
glass position may reduce the intensity of the buffeting.
Manual Open Mode
The sunroof can also be opened by pressing and holding
the switch rearward. Once the switch is held rearward for
more than one second, releasing the switch at any time
during travel will cause the sunroof to stop at the current
position.
