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 gas
purification 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 push button start

2. Push button start
NOTE
If the push button start indicator

being carried, touch the key to the
push button start and start the
engine.
Refer to Engine Start Function When
Key Battery is Dead on page 4-8.
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 (page 7-32). Have your vehicle
inspected at an Authorized Mazda
Dealer as soon as possible.

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 flash es 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-hel d transmitter button
continuously until the indicator light
changes from amber (flashing) 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
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 sec onds 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 syst em 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 4-60).
Verify that the programming has been
erased if you resell the vehicle.
