2008 JEEP LIBERTY Owners Manual

System Operation
The system uses four sensors located in the rear bumper
fascia to scan for obstacles up to 79 inches (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.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 outer most yellow
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 ªRº (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:

GARAGE DOOR OPENER Ð IF EQUIPPED
HomeLinktreplaces up to three remote controls (hand
held transmitters) that operate devices such as garage
door openers, motorized gates, lighting, or home security
systems. The HomeLinktunit operates off your vehicle's
battery.
NOTE:HomeLinktis disabled when the Vehicle Secu-
rity Alarm is active.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 transceiver with a garage
door opener that has a ªstop and reverseº 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 assistance.

WARNING!
Vehicle exhaust contains carbon monoxide, a danger-
ous gas. Do not run your vehicle in the garage while
training the transceiver. Exhaust gas can cause seri-
ous injury or death.
Programming HomeLinkT
Before You Begin
If you have not trained any of the HomeLinktbuttons,
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 HomeLinktfor 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 HomeLinktbutton you wish to program.
Place the hand-held transmitter 1±3 inches (3±8 cm) away
from the HomeLinktbutton you wish to program while
keeping the indicator light in view.
3. Simultaneously press and hold both the chosen
HomeLinktbutton and the hand-held transmitter button
until the HomeLinktindicator changes from a slow to a
rapidly blinking light, then release both the HomeLinkt
and hand-held transmitter buttons.
Watch for the HomeLinktindicator 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 & close while you train.

NOTE:
²Some gate operators and garage door openers may
require you to replace Step #3 with procedures noted
in the ªGate Operator/Canadian Programmingº sec-
tion.
²After training a HomeLinktchannel, if the garage
door does not operate with HomeLinktand the ga-
rage door opener was manufactured after 1995, the
garage door opener may have rolling code. If so,
proceed to the heading ªProgramming A Rolling Code
System.º4. Press and hold the just-trained HomeLinktbutton
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 HomeLinktbutton is pressed.
If the indicator light blinks rapidly for two seconds, and
then turns to a constant light, continue with program-
ming for Rolling Code.
5. PROGRAMMING A ROLLING CODE SYSTEM
At the garage door opener motor (in the garage), locate
the ªlearnº or ªtrainingº button.

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 & close the door).6. Firmly press and release the ªlearnº or ªtrainingº
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 ªLearnº button has been pressed.
7. Return to the vehicle and press the programmed
HomeLinktbutton twice (holding the button for 2 sec-
onds 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 2 seconds) to complete the training.
If you are have any problems, or require assistance,
please call toll-free 1±800±355±3515 or, on the Internet at

Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to ªtime-outº (or quit) after several seconds of
transmission ± which may not be long enough for
HomeLinktto pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed to ªtime-outº in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace ªProgramming
HomeLinktº Step 3 with the following:
3. Continue to press and hold the HomeLinktbutton
while you press and release - every two seconds
(ªcycleº) your hand-held transmitter until HomeLinkthas successfully accepted the frequency signal. The
indicator light will flash slowly and then rapidly when
fully trained.
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under ªProgramming
HomeLinkt.º earlier in this section.
Using HomeLinkT
To operate, simply press and release the programmed
HomeLinktbutton. Activation will now occur for the
trained device (i.e. garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc. The hand-held transmitter of the device may also be
used at any time.
