1-32 In Brief
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
SeeUltrasonic Parking Assist on
page 9‑61.
Power Outlets
Accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone, MP3
player, etc.
The vehicle may have two
accessory power outlets located
below the climate control system,
or may have one accessory power
outlet and one cigarette lighter. The
cigarette lighter is designed to fit
only in the receptacle closest to the
driver.
There may be another accessory
power outlet in the rear cargo area.
If the vehicle has a floor console,
there is an accessory power outlet
inside the storage bin and one on
the rear of the floor console. The accessory power outlets are
powered, even when the ignition is
in LOCK/OFF. Continuing to use
power outlets while the ignition is in
LOCK/OFF may cause the vehicle's
battery to run down.
See
Power Outlets on page 5‑9.Universal Remote System
Vehicles with the Universal Remote
System will have these buttons
located in the headliner. This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to
have another person assist with
programming the transmitter.

Universal Remote System
Programming
Vehicles with the Universal Remote
System will have these buttons
located in the headliner.
This system provides a way to
replace up to three remote control
transmitters used to activate devices such as garage door
openers, security systems, and
home automation devices.
Do not use this system with any
garage door opener that does not
have the stop and reverse feature.
This includes any garage door
opener model manufactured before
April 1, 1982.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to
have another person assist with
programming the transmitter.
Be sure to keep the original remote
control transmitter for use in other
vehicles, as well as for future
programming. Only the original
remote control transmitter is needed
for Fixed Code programming. The
programmed buttons should be
erased when the vehicle is sold or
the lease ends. See
“Erasing
Universal Home Remote Buttons” in
this section. Park the vehicle outside of the
garage when programming a garage
door. Be sure that people and
objects are clear of the garage door
or gate that is being programmed.
Programming Universal Home
Remote
—Rolling Code
For questions or help programming
the Universal Home Remote
System, call 1-866-572-2728 or go
to www.learcar2u.com.
Most garage door openers sold
after 1996 are Rolling Code units.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.

To program up to three devices:
1. From inside the vehicle, pressthe two outside buttons at the
same time for one to
two seconds, and immediately
release them.
2. In the garage, locate the
garage door opener receiver
(motor-head unit). Find the
“Learn” or“Smart” button. It can
usually be found where the hanging antenna wire is
attached to the motor-head unit
and may be a colored button.
Press this button. After pressing
this button, complete the
following steps in less than
30 seconds.
3. Immediately return to the vehicle. Press and hold the
Universal Home Remote button
that will be used to control the
garage door until the garage
door moves. The indicator light,
above the selected button,
should slowly blink. This button
may need to be held for up to
20 seconds.
4. Immediately, within one second, release the button when the
garage door moves. The
indicator light will blink rapidly
until programming is complete.
5. Press and release the same button again. The garage door
should move, confirming that
programming is successful and
complete. To program another Rolling Code
device such as an additional garage
door opener, a security device,
or home automation device, repeat
Steps 1 through 5, choosing a
different function button in Step 3
than what was used for the garage
door opener.
If these instructions do not work, the
garage door opener is probably
a Fixed Code unit. Follow the
programming instructions that follow
for a Fixed Code garage door
opener.

5-58 Instruments and Controls
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
To program up to three devices:
1. To verify that the garage dooropener is a Fixed Code unit,
remove the battery cover on the
hand-held transmitter supplied
by the manufacturer of the
garage door opener motor.
If there is a row of dip switches
similar to the graphic above, the garage door opener is a Fixed
Code unit. If you do not see a
row of dip switches, return
to the previous section for
Programming Universal Home
Remote
—Rolling Code.
Your hand-held transmitter can
have between 8 to 12 dip
switches depending on the
brand of transmitter.
The garage door opener receiver
(motor head unit) could also
have a row of dip switches that
can be used when programming
the Universal Home Remote.
If the total number of switches
on the motor head and
hand-held transmitter are
different, or if the dip switch
settings are different, use the dip
switch settings on the motor
head unit to program the
Universal Home Remote. The
motor head dip switch settings
can also be used when the
original hand-held transmitter is
not available.
Example of Eight Dip Switches with Two Positions
Example of Eight Dip Switcheswith Three Positions
The panel of switches might not
appear exactly as they do in the
examples above, but they
should be similar.

positions, once again firmly
press and release all three
buttons at the same time. The
indicator lights will turn on.
6. Press and hold the button that will be used to control the
garage door until the garage
door moves. The indicator light
above the selected button
should slowly blink. This button
may need to be held for up to
55 seconds.
7. Immediately release the button when the garage door moves.
The indicator light will blink
rapidly until programming is
complete. 8. Press and release the same
button again. The garage door
should move, confirming that
programming is successful and
complete.
To program another Fixed Code

door opener, a security device,
or home automation device, repeat
Steps 1-8, choosing a different
button in Step 6 than what was used
for the garage door opener.
