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.

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 530.
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.Programming Universal Home Remote
Follow these steps to program up to three channels:
1. Press and hold down the two outside
Universal Home Remote buttons, releasing
only when the Universal Home Remote
indicator light begins to ash, after
20 seconds. Do not hold down the buttons for
longer than 30 seconds and do not repeat
this step to program a second and/or
third hand-held transmitter to the remaining
two Universal Home Remote buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
Universal Home Remote buttons while
keeping the indicator light in view.
3. Simultaneously press and hold both the
desired Universal Home Remote button
and the hand-held transmitter button. Do not
release the buttons until Step 4 has been
completed.

Electric Power Management
This vehicle has Electric Power
Management (EPM), an advanced control
system. It estimates the battery’s temperature
and state of charge and then adjusts the voltage
for best performance and extended life of
the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible. SeeDIC Warnings
and Messages on page 222.

Battery Run-Down Protection
This feature shuts off the dome, courtesy, and
vanity lamps if they are left on for more than
20 minutes when the ignition is off. This will keep
the battery from running down.
If the battery run-down protection shuts off the
interior lamps, it may be necessary to do one of
the following to return to normal operation:
Shut off all lamps and close all doors.
Turn the ignition key to RUN.
This feature will also turn off the parking lamps
and headlamps under most circumstances, if they
are left on. If you would like to turn them back
on, turn the exterior lamps knob.
Accessory Power Outlet(s)
With the accessory power outlets, you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
Your vehicle has three accessory power outlets.
There are two outlets located below the climate
controls and one outlet is on the rear of the center
oor console.Remove the cover from the outlet to use the
outlet. Be sure to put the cover back on when not
using the accessory power outlet.
Certain electrical accessories may not be
compatible with the accessory power outlet and
could result in blown vehicle or adaptor fuses.
If you experience a problem, see your dealer
for additional information on the accessory
power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, 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 your battery.
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.
Voltmeter Gage
When your engine is not
running, but the ignition
is in RUN, this gage
displays the battery
voltage in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage
may transition from a higher to lower or a lower to
higher reading, this is normal. Readings between
the low and high warning zones indicate the
normal operating range. The voltmeter gage may
also read lower when in fuel economy mode.
This is normal.

Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 382. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.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.
