After starting a cold engine, the
engine speed increases and a
whining sound from the engine
compartment can be heard.
This is for improved exhaust gaspurification and does not indicate
any parts defect.
Engine-starting is controlled by the
spark ignition system.
This system meets all Canadian
Interference-Causing Equipment
Standard requirements regulating the
impulse electrical field strength of
radio noise.
1. Make sure you are carrying the key.
2. Occupants should fasten their seat belts.
3. Make sure the parking brake is on.
4. Continue to depress the brake
pedal firmly until the engine has
completely started.
5. (Manual transmission)
Continue to depress the clutch
pedal
firmly until the engine has
completely started.
(Automatic transmission)
Put the vehicle in park (P). If you
must restart the engine while the
vehicle is moving, shift into neutral
(N).
NOTE
(Manual transmission)
The starter will not operate if the
clutch pedal is not depressed
sufficiently.
(Automatic transmission)
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.

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 information, 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:
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.

▼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.

2. Detection areas
WARNING
Always check the surrounding area
visually before making an actual lane
change:
The system is only designed to assist
you in checking for vehicles at your rear
when making a lane change. Due to
certain limitations with the operation
of this system, the BSM warning
indicator light, the warning sound and
the warning screen indicator display
may not activate or they might be
delayed even though a vehicle is in an
adjacent driving lane. Always make it
your responsibility as a driver to check
the rear.
NOTE
The BSM will operate when all of the
following conditions are met:

indication/warning light is turned
off.
The shift lever (manual
transmission)/selector lever
(automatic transmission) is shifted
to reverse (R) and the vehicle is
reversing.
The turning radius is small (making
a sharp turn, turning at
intersections).
In the following cases, the
i-ACTIVSENSE warning indication/
warning light turns on and operation
of the system is stopped. If the
i-ACTIVSENSE warning indication/
warning light remains illuminated,
have the vehicle inspected at an
Authorized Mazda Dealer as soon as
possible.
Some problem with the system
including the BSM warning
indicator lights is detected.
A large deviation in the installation
position of a rear side radar sensor
on the vehicle has occurred.
There is a large accumulation of
snow or ice on the rear bumper
near a rear side radar sensor.

flash or the warning beep may be
activated several times when making
a turn at a city intersection.
Turn off the BSM while pulling a
trailer or while an accessory such as a
bicycle carrier is installed to the rear

difficult to view the illumination/
flashing of the BSM warning
indicator lights equipped on the
door mirrors.
Snow or ice is adhering to the door
mirrors.
The front door glass is fogged or
covered in snow, frost or dirt.
