JEEP GRAND CHEROKEE 2007 WK / 3.G SRT Owners Manual

Service the Rear Park Assist System
When the Rear Park Assist System is defective, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display the9SERVICE PARK
ASSIST SYSTEM9message. Refer to ªElectronic Vehicle
Information Center (EVIC)º in Section 4 of this manual.
Cleaning the Rear Park Assist System
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.
CAUTION!
²The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
²The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.

WARNING!
²Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before back-
ing up. You are responsible for safety and must
continue to pay attention to your surroundings. Fail-
ure to do so can result in serious injury or death.
²Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and hitch
ball assembly is disconnected from the vehicle when
the vehicle is not used for towing. Failure to do so
can result in injury or damage to vehicles or ob-
stacles because the hitch ball will be much closer to
the obstacle than the rear fascia when the warning
display turns the red LEDs ON. Also, the sensors
could detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
NOTE:Clean all four Rear Park Assist Sensors regularly,
taking care not to scratch or damage them. The sensors
must not be covered with ice, snow, slush, mud, dirt or
debris. Failure to do so can result in the system not
working properly. The system might not detect an ob-
stacle behind the fascia or it could provide a false
indication that an obstacle is behind the fascia.
Assure objects are not within 11.8 inches (30 cm) from the
rear fascia while driving the vehicle. Failure to do so can
result in the system misinterpreting a close object as a
sensor problem, causing the9SERVICE PARK ASSIST
SYSTEM9message to be displayed in the instrument
cluster.
Ultrasonic noise from airbrakes of nearby trucks, air
powered jackhammers and air powered shop tools, to
name a few, will cause the Rear Park Assist System to be
disabled until the ultrasonic noise is no longer present.

WARNING!
Drivers must be careful when backing up even when
using the rear camera system. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. Failure to do so can
result in serious injury or death.

WARNING!
A moving garage door can cause injury to people and
pets in the path of the door. People or pets could be
seriously or fatally injured. Only use this transceiver
with a garage door opener that has a ªstop and
reverseº feature as required by federal safety stan-
dards. This includes most garage door opener mod-
els manufactured after 1982. Do not use a garage
door opener without these safety features it could
cause injury or death. Call toll-free 1±800±355±3515
or, on the Internet at www.homelink.com for safety
information or assistance.
WARNING!
Vehicle exhaust contains carbon monoxide, a danger-
ous gas. Do not run the vehicle's exhaust while
training the transceiver. Exhaust gas can cause seri-
ous injury or death.
WARNING!
Your motorized door or gate will open and close
while you are training the Universal Transceiver. Do
not train the transceiver 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.

Programming HomeLink
NOTE:When programming a garage door opener, it is
advised to park outside the garage. It is also recom-
mended that a new battery be placed in the hand-held
transmitter of the device being programmed to
HomeLink for quicker training and accurate transmis-
sion of the radio-frequency signal.
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display which includes
HomeLink system messages. The EVIC is located on the
bottom of the tachometer.

1. Press and hold the two outer HomeLink buttons, and
release only when the EVIC display shows ªCHANNELS
CLEAREDº (after 20 seconds).Do nothold the buttons
for longer than 30 seconds anddo notrepeat step one to
program a second and/or third hand-held transmitter to
the remaining two HomeLink buttons.2. Position the end of your hand-held transmitter 1-3
inches (3-8 cm) away from the HomeLink buttons.
3. Simultaneously press and hold both the HomeLink
button that you want to train and the hand-held trans-
mitter buttons.Do not release the buttons until step 4
has been completed.
NOTE:Some gate operators and garage door openers
may require you to replace this Programming Step 3 with
procedures noted in the9Gate Operator/Canadian Pro-
gramming9section.
4. The EVIC display will show ªCHANNEL X TRAIN-
INGº (where X is Channel 1, 2, or 3). Release both buttons

5. Press and hold the just trained HomeLink button and
observe the EVIC display. If the EVIC display shows
ªCHANNEL X TRANSMITº (where X is Channel 1, 2, or
3), programming is complete and your device should
activate when the HomeLink button is pressed and
released.
NOTE:To program the remaining two HomeLink but-
tons, begin with9Programming9step two. Do not repeat
step one.
NOTE:If your hand-held transmitter appears to pro-
gram the universal transceiver, but your garage door
does not operate using the transmitter and your garage
door opener was manufactured after 1995, your garage
door opener may have a multiple security code system
(rolling code system). Please proceed to steps 6±8 to
complete the programming of a rolling code equipped
device (most common garage door openers require this
step.6. At the garage door opener receiver (motor-head unit)
in the garage, locate the9learn9or9smart9button. This
can usually be found where the hanging antenna wire is
attached to the motor-head unit.
7. Firmly press and release the9learn9or9smart9button.
(The name and color of the button may vary by manu-
facturer.)
NOTE:There are 30 seconds in which to initiate step

Canadian Programming/Gate 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-
ming9procedures (regardless of where you live),replace
(Programming HomeLink(step 3with 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.3. Continue to press and hold the HomeLink button
while youpress and release every two seconds(9cycle9)
your hand-held transmitter until the frequency signal has
successfully been accepted by HomeLink. The EVIC
display will show ªCHANNEL X TRAINEDº (where X is
Channel 1, 2, or 3). Proceed with9Programming9step
four to 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.com or 1-800-355-
3515.
