Programming the Transmitter
Do not use the HomeLink
Transmitter with any garage
door opener that does not have the ªstop and reverseº
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the HomeLink Transmitter so that you can
still see the indicator light.

2-60 Operating the Transmitter
Press and hold the appropriate button on the
HomeLink
Transmitter. The indicator light comes on
while the signal is being transmitted.
If the hand
-held transmitter appears to program the
HomeLink Transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a ªrolling
codeº system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.
To determine if you have this system, press the
button on the HomeLink Transmitter that you have
programmed already. If the indicator light flashes
rapidly for one to two seconds, then turns solid, the
garage door opener has a rolling code system. In a
rolling code system, the garage door motor head unit
must be trained to the HomeLink Transmitter.
Training a Garage Opener with a ªRolling
Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to the HomeLink
Transmitter, see
ªProgramming the Transmitterº listed previously. If you
have completed this programming already, you now
need to train the garage door opener motor head unit to
recognize the HomeLink Transmitter. Refer to your
garage door opener owner's manual for the proper
transmitter training procedure for your garage door
opener brand.
1. Find the training button on the garage door opener
motor head unit. The exact location and color will
vary by garage door opener brand. If you have
difficulty finding the training button, refer to your
garage door opener owner's manual. Because of the
steps involved, it may be helpful to have another
person assist in programming the transmitter.
2. Press the training button on the garage door
opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.

2-78 Trans Fluid Hot
Your vehicle has a transmission temperature warning
display contained in the message center.
If the transmission fluid
temperature becomes high,
the message center will
display this message.
When the transmission enters the protection mode,
you may notice a change in the transmission shifting
patterns. When the transmission fluid temperature
returns to normal, the display will turn off and the
transmission shifting patterns will return to normal.
NOTICE:
If you keep driving your vehicle with the
transmission TRANS FLUID HOT message
displayed, you can damage the transmission. This
could lead to costly repairs that may not be
covered under your warranty.
The following situations can cause the transmission to
operate at higher temperatures:

Towing a trailer

Hot outside air temperatures

Hauling a large or heavy load

Low transmission fluid level

High transmission fluid level

Restricted air flow to the radiator and the auxiliary
transmission oil cooler (if equipped).
A temporary solution to hotter transmission operating
temperatures may be to let the transmission cool down.
If the transmission is operated at higher temperatures on
a frequent basis, see ªScheduled Maintenanceº in the
Index for the proper transmission maintenance intervals.

3-8 Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The A/C button, below the mode knob, allows the
air coming into your vehicle to be cooled. This setting
is useful for normal cooling on hot days. When you
use A/C with the recirculation button pushed in,
turn off recirculation as soon as the vehicle reaches a
comfortable interior temperature.
Using A/C with the recirculation setting active
allows the air inside your vehicle to be recirculated.
This setting helps to maximize your air conditioner's
performance and your vehicle's fuel economy.
This setting also cools air the fastest and can be used
to keep unwanted odors and/or dust from entering the
vehicle. When using the air conditioner, turn off the
recirculation setting and use the outside air setting after
the vehicle reaches a comfortable interior temperature.
When the right knob on the control panel is between
heater and defrost, the recirculation feature will not
function to reduce window fogging.Passenger Compartment Air Filter
Your vehicle is equipped with a passenger compartment
air filter, which filters outside air entering the vehicle.
For information on replacing the filter see ªPassenger
Compartment Air Filterº in the Index.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the heater or vent/heat
setting with the temperature knob in the red area.
On cold days, approximately 32
F (
-0
C) or
lower, you may experience differences in how
the transmission shifts until the engine is warm.
This feature automatically reduces the time it takes for
the engine to reach normal operating temperature and
shortens the time it takes the heater to reach full output.
If you use the engine coolant heater before starting
your engine in cold weather, 20
F (
-8
C) or lower,
the heating system will produce warmer air faster to heat
the passenger compartment.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature. For more information, see ªEngine Coolant
Heaterº in the Index.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, turn the
fan knob all the way to the right for a few moments
before driving. This helps clear the intake ducts of
snow and moisture, and reduces the chance of
fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

The use of hood air deflectors may adversely
affect the performance of the heating and air
conditioning system.Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is off. See ªRetained
Accessory Powerº in the Index.
Setting the Clock
Press and hold HR until the correct hour appears on the
display. Press and hold MN until the correct minute

ignition off, press RECALL or HR/MN and the time
will be displayed for a few seconds. There is an initial
two
-second delay before the clock goes into the
time
-set mode.
