Programming Universal Home
Remote — Fixed Code
Fixed Code garage door openers are used for
garage doors produced prior to 1996. Fixed code
uses the same coded signal every time, which
is manually programmed by setting DIP switches
for a unique personal code.
Follow these steps to program up to three channels:
1. Remove the battery cover of the hand-held
transmitter.
2. Write down the eight to 12 coding switch
settings from left to right. When the switch
is in the up position, write “on,” and when a
switch is in the down position, write “off”.
If a switch is set between the up and down
position, write “middle”.
3. Enter these positions into the Universal Home
Remote System as follows.
Press and release all three buttons at the same
time to put the device into programming mode.

Universal Home
Remote System Operation
(With One Triangular LED)
Your vehicle may have the Universal Home
Remote System. If there is one triangular Light
Emitting Diode (LED) above the Universal
Home Remote buttons, follow the instructions
below. If your vehicle has three round LED above
the Universal Home Remote buttons, follow the
instructions under Universal Home Remote System
Operation (with three round LED).
Do not use the Universal Home Remote 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.If you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8 to
complete the programming of your Universal Home
Remote Transmitter.
Read the instructions completely before attempting
to program the Universal Home Remote. Because
of the steps involved, it may be helpful to have
another person available to assist you in the
programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that
upon the sale of the vehicle, the programmed
Universal Home Remote buttons should be erased
for security purposes. See “Erasing Universal
Home Remote Buttons” later in this section or,
for assistance, seeCustomer Assistance Offices
on page 540.
Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to
park outside of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.

Reading Lamps
Your vehicle has reading lamps located in the
overhead console. Press the button located next
to the lamp to turn it on. The lamps can be
adjusted to point in the direction you want.
Press the button again to turn the lamp off.
These lamps will also come on with the
dome lamps.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are
left on for more than 10 minutes when the
ignition is in LOCK. This will help prevent the
battery from running down.
Rear Vision Camera
Your vehicle may be equipped with a rear vision
camera system. Read this entire section before
using the camera system.The rear vision camera system is designed to help
the driver when backing up by displaying a view
of the area behind the vehicle. When the
driver shifts the vehicle into REVERSE (R), the
video screen will automatically slide out from
the rear view mirror. Once the driver shifts out of
REVERSE (R), the video screen will slide back
into the rear view mirror after a delay.
To turn off the rear vision camera system, do the
following:
1. Place the vehicle shift lever in (P) PARK.
2. Turn the ignition key to the ACCESSORY
position.
3. Press the right mirror button briey; the right
green light indicator will turn off. The rear
camera vision display is now disabled.
To turn on the rear camera vision feature again,
press the right mirror button briey. The green light
indicator will illuminate. The rear camera vision
system is now enabled and the display will
slide out from the mirror normally.

{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 84, for more on this, including
important safety information.
Charging System Light
The charging system
light will come on briey
when the ignition is on,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain the battery.
When this light comes on the DIC will also display
the SERVICE BATTERY CHARGING SYSTEM
message. SeeDIC Warnings and Messages
on page 226for more information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
209

Voltmeter Gage
When your engine is not
running, but the ignition
is in RUN, this gage
shows your battery’s
state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings
between the low and high warning zones indicate
the normal operating range.Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left at
an idle for an extended period. This condition
is normal since the charging system is not able to
provide full power at engine idle. As engine
speeds are increased, this condition should correct
itself as higher engine speeds allow the charging
system to create maximum power.
You can only drive for a short time with the
reading in either warning zone. If you must drive,
turn off all unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system. Have
the vehicle serviced as soon as possible.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your dealer
can prepare the vehicle for inspection.
Oil Pressure Gage
The oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) when the
engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings
above the low pressure zone indicate the normal
operating range.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another.
Some messages may not require immediate
action. Press any of the DIC buttons on the
steering wheel or the trip odometer reset stem
located on the instrument panel cluster to
acknowledge that you received the messages and
to clear them from the display.
Some messages cannot be cleared from the
display because they are more urgent. These
messages require action before they can be
removed from the DIC display. Take any messages
that appear on the display seriously and remember
that clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
BATTERY NOT CHARGING
This message displays if the battery is not
charging during operation. Driving with this
problem could drain the battery. Have the electrical
system checked as soon as possible by your
