How to Use the
Advanced Keyless Entry System
The system operates only when the
driver is in the vehicle or within
operational range while the key is
being carried (Except during power
saving function operation).
NOTE
The advanced keyless entry system
functions can be deactivated to
prevent any possible adverse effect
on a user wearing a pacemaker or
other medical device. If the system is
deactivated, you will be unable to
start the hybrid system by carrying
the key. Consult an Authorized
Mazda Dealer for details. If the
advanced keyless entry system has
been deactivated, you can start the
hybrid system by following the
procedure indicated when the key
battery goes dead.
Refer to Starting the hybrid system
with a dead key battery on page
8-9.
When the battery power is low, or in
places where there are high-intensity
radio waves or noise, the operational
range may become narrower or the
system may not operate.

NOTE
The system may not operate if you
are too close to the windows or door

If the key is left in the following areas
and you leave the vehicle, the doors
may be locked depending on the
radio wave conditions even if the key
is left in the vehicle.

Target object is thin such as wire,
rope, or poles.
Target object absorbs waves easily
such as cotton or snow.
Target object has an angular shape.Target object is tall and wide at the
upper part.
Target object height is low.There are multiple target objects.Target objects are too close to the
sensors.
Ice, snow, or mud is adhering to
the sensor area.
Heavy rainfall or pressurized water
is applied to the sensor area.
The sensor areas are frozen.You cover the sensor with your
hand.
The area around the sensor has
received a strong impact.
The vehicle is excessively tilted.Under extremely hot or cold
weather.
Approached by an object that
generates ultrasonic waves, such as
the horn of another vehicle, the
engine noise of a motorcycle, the
air brake noise of a large vehicle,
or the sensor of another vehicle.
A commercially-available fender
pole or an antenna for a radio
transmitter is installed to the
vehicle.
The vehicle is moving towards a tall
or square curbstone, or a steep
grade.
The vehicle is moving towards an
uneven wall or stairs.
The vehicle is driven in a place with
low ceilings.
The vehicle is driven on bumpy
roads, inclines, gravel roads, dense
grass, or grating.
The ultrasonic sensor does not detect
target objects directly beneath the
bumper. Even if target objects which
are located at a position lower than
an ultrasonic sensor have been
detected, the ultrasonic sensor may
suddenly stop detecting as the
vehicle approaches the target object.

How to Use the
HomeLink Wireless Control System
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. Verify that there is a remote control transmitter available for the device
you would like to program.
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.
2. 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
3. Hold the hand-held transmitter 3 to 7 cm (1.2 to 2.7 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
about 20 cm (7.9 in) away from the
HomeLink button.
4. Press the hand-held transmitter button continuously until the
indicator light changes from amber
(flashing) to green (on/flashing).
NOTE
Some gate operators and garage
door openers may require you to
replace this Programming Step 4
with procedures noted in the “Gate
Operator/Canadian Programming”
section.
5. Press the HomeLink button again to check if the programming has been
completed.
If the indicator light remains on in
green, the programming is
complete and the device becomes
operational.
If the indicator light flashes rapidly
in green, firmly press and hold the
Homelink button and release it
after two seconds have passed.
Repeat this process up to three
times to complete the
programming. The device becomes
operational and programming is
complete. If the device does not
operate, go to the next step.
6. At the garage door opener receiver (motor-head unit) in the garage,
locate the “learn” or “smart” button.
This can usually be found where the
hanging antenna wire is attached to
the motor-head unit.
7. Firmly press and release the “learn” or “smart” button. (The name and
color of the button may vary by
manufacturer.)
