ffect
medical devices such as pacemakers:
Before using the key near people who
use medical devices, ask the medical
device manufacturer or your physician
if radio waves from the key will aff ect

Using these garage door openers can
increase the risk of serious injury or
death. For further in formation, contact
HomeLink at www.homelink.com or
www.youtube.com/HomeLinkGentex
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 quic
ker 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.
▼ Programming the HomeLink
System
The HomeLink system provides 3
buttons which can be individually
selected and programmed using the
transmitters for current, on-market
devices as follows:
1. Press and release the HomeLink
button you would like to program.
The indicator light flashes slowly in
amber when the button is pressed.
1. Indicator light
2. HomeLink button
2. Hold the hand-held transmitter 2.5
to 7.5 cm (1 to 3 in) away from the
HomeLink button you would like to
program while keeping the
indicator light in view.
NOTE
Depending on the hand-held
transmitter, it may be easier to do
the programming by holding it 15
to 20 cm (6 to 7.8 in) away from
the HomeLink button.
3. Press the hand-held transmitter button continuously until the
indicator light changes from amber
(fl ashing) to green
(on/flashing).

▼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. Similar to
this Canadian law, some U.S. gate
operators are designed to “time-out”
in the same manner.

If you live in Canada or are having
di fficulties programming a gate
operator by using the programming
procedures (regardless of where you
live), replace Step 3 of Programming
the HomeLink System 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.
While the indicator light is flashing in
amber, press the button on the
hand-held transmitter for 2 seconds
and release it repeatedly until the
indicator light changes from amber to
green.
Go back to Step 4 of Programming the
HomeLink System to complete the
procedure.
▼ Operating the HomeLink System
Press the programmed HomeLink
button to operate a programmed
device.
▼
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. After 20 seconds, the indicator light
fl ashes in amber. After the indicator
light flashes, release the HomeLink
button.
3. Go back to Step 2 of Programming the HomeLink System to complete
the procedure.
NOTE
If the programming has not been
completed, the system returns to the
previous programming.
▼Erasing Programmed HomeLink
Buttons
NOTE
All of the programmed HomeLink
buttons are reset. Individual buttons
cannot be reset, however, individual
buttons can be reprogrammed. For
individual button reprogramming,
refer to Reprogramming the
HomeLink System (page 4-63).
Verify that the programming has
been erased if you resell the vehicle.
