Using these garage door openers can
increase the risk of serious injury or death.
For further information, contact HomeLink
at 1-800-355-3515 or www.homelink.com
or an Authorized Mazda Dealer.
Always check the areas surrounding
garage doors and gates for people or
obstructions before programming or
during operation of the HomeLink system:
Programming or operating the HomeLink
system without verifying the safety of areas
surrounding garage doors and gates is
dangerous and could result in an
unexpected accident and serious injury if
someone were to be hit.
NOTE
The programming will not be erased even
if the battery is disconnected.
▼Pre-programming the HomeLink
System
NOTE
It is recommended that a new battery be
placed in the hand-held transmitter of the
device being programmed to HomeLink
for quicker training and accurate
transmission of the radio-frequency signal.
Verify that there is
a remote control
transmitter available for the device you
would like to program.
Disconnect the power to the device.
▼ Programming the HomeLink
System
CAUTION
When programming a garage door opener
or a gate, disconnect the power to these
devices before performing programming.
Continuous operation of the devices could
damage the motor.
The HomeLink system provides 3 buttons
which can be individually selected and
programmed using the transmitters for
current, on-market devices as follows:
1. Disconnect the power to the garage
door opener or gate programmed to the
hand-held transmitter.
2. Position the end of your hand-held transmitter 2.5―7.5 cm (1―3 inches)
away from the HomeLink button you
wish to program while keeping the
indicator light in view.
3. Simultaneously press and hold both the chosen HomeLink and hand-held
transmitter buttons. Do not release the
buttons until step 3 has been
completed.
NOTE
Some gate operators and garage door
openers may require you to replace
this Programming Step 2 with
procedures noted in the “Gate
Operator/Canadian Programming”
section.
4. After the HomeLink indicator light changes from a s low to a rapidly
blinking light, release both the
HomeLink and hand-held transmitter
buttons.

▼Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission ―
which may not be long enough for
HomeLink to pick up the signal during
programming. Simila
r to this Canadian
law, some U.S. gate ope rators are designed
to “time-out” in the same manner.

If you live in Canada or you are having
difficulties progra mming a gate operator
by using the “Programming” procedures
(regardless of where you live), replace
“Programming HomeLink” step 3 with
the following:
NOTE
If programming a garage door opener or
gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
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 successfully been accepted by
HomeLink. (The indicator light will flash
slowly and then rapidly.)
Proceed with “Programming” step 4 to
complete.
▼ Operating the HomeLink System
Press the programmed HomeLink button
to operate a programmed device. The code
will continue being transmitted for a
maximum of 20 seconds.
▼Reprogramming the HomeLink
system
To program a device to HomeLink using a
HomeLink button previously trained,
follow these steps:
1. Press and hold the desired HomeLink
button. DO NOT release the button.
2. The indicator light will begin to flash after 20 seconds. Without releasing the
HomeLink button, proceed with
“Programming” - step 1.
▼Erasing Programmed HomeLink
Buttons
To erase the existing programming from
all three operating
channels, press and
hold the two outside buttons (
, ) on
the auto-dimming mirror until the
HomeLink indicator light begins to flash
after approximately 10 seconds.
Verify that the programming has been
erased when you re sell the vehicle.
