JEEP LIBERTY 2009 KK / 2.G Owners Manual

System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep the Rear Park Assist System operating prop-
erly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the Rear Park Assist System.
•When you turn off the Rear Park Assist System, the
instrument cluster will display “PARK ASSIST DIS-
ABLED.” Furthermore, once you turn off the Rear
Park Assist System, it remains off until you turn it on
again, even if you cycle the ignition key.
•When you move the shift lever to the REVERSE
position and the Rear Park Assist System is turned off,
a single chime will sound once per ignition cycle and
the instrument cluster will display “PARK ASSIST
DISABLED.”
•The Rear Park Assist System, when on, will MUTE the
radio when it is sounding a tone.
•If a Rear Park Assist System malfunction occurs, a
single chime will sound once per ignition cycle. In
addition, the Electronic Vehicle Information Center
(EVIC) will display “SERVICE PARK ASSIST SYS-
TEM” and the LED in the Rear Park Assist switch will
illuminate. If this occurs, see your authorized dealer
for service.
CAUTION!
•The 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.(Continued)

CAUTION! (Continued)
•The 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.
•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.
WARNING!
•Drivers 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 be-
fore backing up. You are responsible for safety and
must continue to pay attention to your surround-
ings. Failure to do so can result in serious injury or
death.(Continued)
160 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING! (Continued)
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and
hitch ball assembly is disconnected from the ve-
hicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to
vehicles or obstacles 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.
Enabling and Disabling the System
There are times when you may want to disable the Rear
Park Assist System, such as when towing a trailer.
Vehicles Equipped With the Electronic Vehicle
Information Center (EVIC)
You can turn the Rear Park Assist System on or off
through the EVIC. For details, refer to “Personal Settings
(Customer-Programmable Features)” under “Electronic
Vehicle Information Center (EVIC)” in Section 4 of this
manual.

Vehicles Equipped with Rear Park Assist Switch
You can turn the Rear Park Assist System on or off by
pressing the Rear Park Assist switch located the lower
switch bank below the climate controls.System Operation
The system uses four sensors located in the rear bumper
fascia to scan for obstacles up to 79 in (200 cm) away from
the rear bumper fascia. The warning display located
above the rear window provides both visible and audible
warnings to indicate the range of the object.

Rear Park Assist LED Display
162 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The warning display contains two sets of yellow and red
LEDs, one set to warn of obstacles behind the left rear of
the vehicle and the other set to warn of obstacles behind
the right rear of the vehicle. The driver can view the LEDs
either through the rear view mirror or by looking at the
display above the rear window.
When the ignition is turned to the ON position, and the
system is enabled, the warning display will turn on all of
its LEDs for approximately one second. Then, the system
dimly illuminates the two inner most LEDs when it is
detecting no obstacles.The Rear Park Assist System is active when the ignition is
in the ON position, and the system is enabled, and the
driver shifts the transmission into the REVERSE position,
and the vehicle speed is less than 11 mph (18 km/h). The
following chart shows the warning display operation
when the system is detecting an obstacle:

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. Only use this trans-
ceiver with a garage door opener that has a “stop
and reverse” feature as required by Federal safety
standards. This includes most garage door opener
models manufactured after 1982. Do not use a
garage door opener without these safety features.
Call toll-free 1–800–355–3515 or, on the Internet at
www.HomeLink.com for safety information or as-
sistance.
•Vehicle exhaust contains carbon monoxide, a dan-
gerous gas. Do not run your vehicle in the garage
while training the transceiver. Exhaust gas can
cause serious injury or death.
Programming HomeLink
Before You Begin
If you have not trained any of the HomeLink buttons,
erase all channels before you begin training.
To do this, press and hold the two outside buttons for
20 seconds until the red indicator flashes.
It is recommended that a new battery be placed in the
hand-held transmitter of the device being programmed
to HomeLink for more efficient training and accurate
transmission of the radio-frequency signal.
Your vehicle should be parked outside of the garage
when programming.
1. Turn the ignition switch to the ON/RUN position.
2. Hold the battery side of the hand-held transmitter
away from the HomeLink button you wish to program.
166 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Place the hand-held transmitter 1–3 in (3-8 cm) away
from the HomeLinkbutton you wish to program while
keeping the indicator light in view.
3. Simultaneously press and hold both the chosen
HomeLink button and the hand-held transmitter button
until the HomeLink indicator changes from a slow to a
rapidly blinking light, then release both the HomeLink
and hand-held transmitter buttons.
Watch for the HomeLink indicator to change flash rates.
When it changes, it is programmed. It may take up to
30 seconds, or longer in rare cases. The garage door may
open and close while you train.
NOTE:
•Some gate operators and garage door openers may
require you to replace Step 3 with procedures noted in
the “Gate Operator/Canadian Programming” section.
•After training a HomeLink channel, if the garage
door does not operate with HomeLink and the ga-
rage door opener was manufactured after 1995, the
garage door opener may have a rolling code. If so,
proceed to the heading “Programming A Rolling Code
System.”
4. Press and hold the just-trained HomeLink button
and observe the indicator light.
If the indicator light stays on constantly, programming is
complete and the garage door (or device) should activate
when the HomeLink button is pressed.
If the indicator light blinks rapidly for two seconds, and
then turns to a constant light, continue with program-
ming for a Rolling Code.
5. PROGRAMMING A ROLLING CODE SYSTEM
At the garage door opener motor (in the garage), locate
the “Learn” or “Training” button.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 167

This can usually be found where the hanging antenna
wire is attached to the garage door opener motor (it is
NOT the button normally used to open and close the
door).6. Firmly press and release the “Learn” or “Training”
button. The name and color of the button may vary by
manufacturer.
NOTE:
There are 30 seconds in which to initiate the next
step after the “Learn” button has been pressed.
7. Return to the vehicle and press the programmed
HomeLink button twice (holding the button for two
seconds each time). If the device is plugged in and
activates, programming is complete.
If the device does not activate, press the button a third
time (for two seconds) to complete the training.
If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at
www.HomeLink.com for information or assistance.
To program the remaining two HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
