HomeLink®Wireless Control
System Operation
Do not use the HomeLink®Transmitter 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 HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
Internet at: www.homelink.com or by calling
1-800-355-3515.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.
Programming HomeLink®
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the 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
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured
to “time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the “Programming
HomeLink
®” procedures (regardless of where you live),
replace Step 3 under “Programming HomeLink®” with
the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
®. The
indicator light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming HomeLink
®”
to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for
at least half of a second. The indicator light will come on
while the signal is being transmitted.
Erasing HomeLink®Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
Do not hold the two outside buttons for longer
than 30 seconds.
2. Release both buttons.
HomeLink
®is now in the train (learning) mode and
can be programmed at any time beginning with Step 2
under “Programming HomeLink
®” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a Single
HomeLink
®Button” following this section.

You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
#MAX (Maximum Air Conditioning):Turn the
right knob to this position for maximum air conditioning.
This will select air conditioning and recirculation for
maximum cooling of your vehicle.

Time Elapsed
Press the information button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you can
clock the time it takes to get from one point to another.
Each of the elds for the hours, minutes, and seconds
are two numeric digits.
Once TIME ELAPSED :00 is displayed, press the
set/reset button to start the timing feature. Press the
set/reset button again to stop it. If you will be starting
and stopping your vehicle, during a trip for instance, the
TIME ELAPSED feature will automatically start timing
where it left off when you last stopped. To reset it,
press and hold the set/reset button for approximately
1.5 seconds. The display will return to zero.
Average Speed
Press the information button until AVERAGE SPEED
displays. This mode shows the average speed of
the vehicle in miles per hour (mph) or kilometers
per hour (km/h). This average is calculated based on
the various vehicle speed recorded since the last reset
of this value. To reset the value, press the information
button to display AVERAGE SPEED, then press
and hold the set/reset button. The display will return
to zero.
Fuel Range
Press the information button until FUEL RANGE
displays. This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance travelled, fuel used, fuel capacity, etc. This
estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode may read one number, but if the vehicle
is driven on a freeway, the number may change even
though the same amount of fuel is in the fuel tank.
This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See
“LOW FUEL” underDIC Warnings and Messages on
page 3-51for more information.
3-47

Average Fuel Economy
Press the information button until AVG ECONOMY
displays. This mode shows the approximate average
miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). This number is calculated based on the
number of mpg (L/100 km) recorded since the last time
this menu item was reset. To reset AVG ECONOMY,
press and hold the set/reset button. The display
will return to zero.
Instantaneous Fuel Economy
Press the information button until INST ECONOMY
displays. This mode shows the current fuel economy
at a particular moment and will change frequently
as driving conditions change. This mode shows the
instantaneous fuel economy in miles per gallon (mpg)
or liters per 100 kilometers (L/100 km). Unlike average
fuel economy, this screen cannot be reset.
Battery
Press the information button until BATTERY displays.
This mode shows the current battery voltage.
If there is a problem with the battery charging system,
a DIC message will display. SeeDIC Warnings and
Messages on page 3-51for more information.Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal.
Oil Life
Press the information button until OIL LIFE displays.
This mode shows an estimate of the oil’s remaining
useful life. If you see OIL LIFE 99% on the display, that
means 99% of the current oil life remains. The engine
oil life system will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the LOW OIL
PRESSURE message will appear on the display.
You should change your oil as soon as possible. See
Engine Oil on page 5-13. In addition to the engine oil life
system monitoring the oil life, additional maintenance
is recommended in the Maintenance Schedule in
this manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.

5. To start the compass calibration, press and hold
the set/reset button until CALIBRATION BEGUN
DRIVE UNTIL DONE appears in the DIC display.
6. Drive the vehicle slowly in a circle two times to
activate the compass.
When the calibration is complete, the DIC will
display CALIBRATION FINISHED.
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, but
you can press any of the DIC buttons to acknowledge
that you received the message and clear it from the
DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared.If there are any active warning messages when the
vehicle is turned off, two chimes will sound and the
DIC will go into a reminder mode. The reminder
mode displays any active message. If there are multiple
messages, the DIC will display each message for
ve seconds. After each active message is displayed
once, the reminder mode will turn off.
You should 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.
A/C OFF FOR ENGINE PROTECTION
This message will display when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-39.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the
air conditioning compressor will turn back on. You can
continue to drive your vehicle.
This message will come on while the ignition is in RUN.
Press any of the DIC buttons to acknowledge this
warning message and to clear it from the screen.
