▼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.

*1 The recognition distance of the ForwardSensing Camera (FSC) varies according to
the surrounding conditions.
The warning light turns on when the
system has a malfunction.
Refer to High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-34.
CAUTION
Do not adjust the vehicle height,
modify the headlight units, or
remove the camera, otherwise the
system will not operate normally.
 Do not rely excessively on the HBC
and drive the vehicle while paying
su fficient attention to safety. Switch
the headlights between the high
beams and low beams manually if
necessary.
NOTE
The timing in which the system
switches the headlights changes under
the following conditions. If the system
does not switch the headlights
appropriately, manually switch
between high and low beams
according to the visibility as well as
road and tra ffic conditions.
When there are sources of light in
the area such as street lamps,
illuminated signboards, and tra ffic
signals.
When there are re flective objects in
the surrounding area such as
re flective plates and signs.
When visibility is reduced under rain,
snow and foggy conditions.
When driving on roads with sharp
turn or hilly terrain.
When the headlights/rear lamps of
vehicles in front of you or in the
opposite lane are dim or not
illuminated.
When there is insu fficient darkness
such as at dawn or dusk.
When the trunk/luggage
compartment is loaded with heavy
objects or the rear passenger seats
are occupied.
When visibility is reduced due to a
vehicle in front of you spraying water
from its tires onto your windshield.
▼ To Operate the System
The HBC operates to switch the
headlights automatically between high
and low beams after the ignition is
switched ON and the headlight switch
is in the AUTO and low beam position.
The HBC determines that it is dark
based on the brightness of the
surrounding area. At the same time,
the HBC indicator light (green) in the
instrument cluster illuminates.

NOTE
Operation of the HBC function can be
disabled.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
