3. Make sure the parking brake is on.
4. Continue to depress the brake pedal firmly until the engine has
completely started.
5. Put the vehicle in park (P). If you must restart the engine while the
vehicle is moving, shift into neutral
(N).
NOTE
The starter will not operate if the
selector lever is not in P or N
position and the brake pedal is not
depressed sufficiently.
6. Make sure that the KEY indicator light (green) in the instrument
cluster and push button start
indicator light (green) turns on.

the engine.
Refer to Engine Start Function
When Key Battery is Dead on
page 4-7.
CAUTION
If the KEY warning indication (red)
is displayed, or the push button
start indicator light (amber) flashes,
this could indicate a problem with
the engine starting system. This may
prevent the engine from starting or
from switching the ignition to ACC
or ON.
Refer to KEY Warning Indication/
Warning Light (Red) on page
7-26.
Have your vehicle inspected at an
Authorized Mazda Dealer as soon
as possible.
NOTE
Under the following conditions,
the KEY warning indication (red)
is displayed after the push button
start is pressed. This informs the
driver that the push button start
will not switch to ACC, even if it
is pressed from off (page 7-26).
The key battery is dead.The key is out of operational
range.

▼ HomeLink Wireless Control
System
NOTE
HomeLink and HomeLink house are
registered trademarks of Gentex
Corporation.
The HomeLink system replaces up to 3
hand-held transmitters with a single
built-in component in the
auto-dimming mirror. Pressing the
HomeLink button on the
auto-dimming mirror activates garage
doors, gates and other devices
surrounding your home.

2. HomeLink button
WARNING
Do not use the HomeLink system with
any garage door opener that lacks the
safety stop and reverse feature:
Using the HomeLink system with any
garage door opener that lacks the
safety stop and reverse feature as
required by federal safety standards is
dangerous. (This includes garage doors
manufactured before April 1, 1982.)
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 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.
▼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:

Two-Way Communication.

NOTE
To program the remaining two
HomeLink buttons, go back to Step 1
of Programming the HomeLink System
and repeat the procedure.
For questions or comments, please
contact HomeLink at

HomeLinkGentex , or the HomeLink
toll-free hotline at 1-800-355-3515
(for calls placed outside of the USA,
Canada, and Puerto Rico, international
rates will apply and may differ based
on landline or mobile phone).
▼ 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
difficulties 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
flashes 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.

WARNING
Always check the surrounding area
visually before actually putting the
vehicle in reverse:
The system is only designed to assist
you in checking for vehicles at the rear
when putting the vehicle in reverse.
Due to certain limitations with the
operation of this system, the Blind Spot
Monitoring (BSM) warning indicator
lights may not flash or it might be
delayed even though a vehicle is
behind your vehicle. Always make it
your responsibility as a driver to check
the rear.
RCTA operation
1. The RCTA system operates when the selector lever is shifted to the
reverse (R) position.
2. If there is the possibility of a collision with an approaching
vehicle, the Blind Spot Monitoring
(BSM) warning indicator lights
flashes and the warning beep is
activated simultaneously.
