2017 MAZDA MODEL CX-5 ECU

Modification and Add-OnEquipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modified or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do not
modify the system or install any add-on
equipment to the immobilizer and the
theft-deterrent systems or the vehicle.
Immobilizer System
The immobilizer syste m allows the engine
to start only with a key the system
recognises.

If someone attempts to start the engine
with an unrecognised key, the engine will
not start, thereby helping to prevent
vehicle theft.
If you have a problem with the
immobilizer system or the key, consult an
Authorised Mazda Repairer.
CAUTION
 Changes or
modifications not expressly
approved by the party responsible for
compliance could void the user's
authority to operate the equipment.
 To avoid damage to the key, do not:
 Drop the key.
 Get the key wet.
 Expose the key to any kind of magnetic
field.
 Expose the key to high temperatures
on places such as the instrument panel
or bonnet, under direct sunlight.
 If the engine does not start with the
correct key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorised Mazda Repairer.
NOTE
•The keys carry a unique electronic code.
For this reason, and to assure your
safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorised
Mazda Repairer.

•Always keep a spare key in case one is
lost. If a key is lost, consult an
Authorised Mazda Repairer as soon as
possible.
•If you lose a key, an Authorised Mazda
Repairer will reset the electronic codes
of your remaining keys and immobilizer
system. Bring all the remaining keys to
an Authorised Mazda Repairer to reset.
Starting the vehicle with a key that has
not been reset is not possible.
▼Operation
NOTE
•The engine may not start and security
indicator light may illuminate or flash if
the key is placed in an area where it is
difficult for the system to detect the
signal, such as on the instrument panel
or in the glove comp
artment. Move the
key to a location within the signal
range, switch the ignition off, and then
restart the engine.
•Signals from a TV or radio station, or
from a transceiver or mobile telephone
could interfere with your immobilizer
system. If you are using the proper key
and the engine fails to start, check the
security indicator light.
Arming
The system is armed when the ignition is
switched from ON to off.
The security indica tor light in the
instrument cluster flashes every 2 seconds
until the system is disarmed.

Disarming
The system is disarmed when the ignition
is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
flashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart the
engine. If the engine d oes not start after 3
or more tries, contact an Authorised
Mazda Repairer.
NOTE
•If the security indicator light flashes
continuously while you are driving, do
not shut off the engine. Go to an
Authorised Mazda Repairer and have it
checked. If the engine is shut off while
the indicator light is flashing, you will
not be able to restart it.
•Because the electronic codes are reset
when the immobilizer system is repaired,
the keys are needed. Make sure to bring
all the keys to an Authorised Mazda
Repairer so that they can be
programmed.

Theft-Deterrent System*
If the theft-deterrent system detects an
inappropriate entry in to the vehicle or the
intrusion sensor detects movement in the
vehicle which could result in the vehicle
(with the intrusion sensor) or its contents
being stolen, the alarm alerts the
surrounding area of an abnormality by
sounding the siren/horn and flashing the
hazard warning lights.

The system will not function unless it's
properly armed. So when you leave the
vehicle, follow the arming procedure
correctly.
Intrusion sensor
*
The intrusion s ensor uses ultrasonic waves
to detect movement inside the vehicle and
to raise an alert of an intrusion into the
vehicle.

The intrusion s ensor detects certain kinds
of movement inside the vehicle, however,
it may also respond to phenomenon
outside the vehicle such as vibrations, loud
noise, wind, and air currents.
CAUTION
In order for the intrusion sensor to operate
appropriately, be aware of the following:
 Do not hang clothing or objects from a
head restraint or a coat hook.
 Return the extension sunvisors to their
original positions.
 Do not blind the intrusion sensor by
covering it or placing objects over it.
 Do not allow the intrusion sensor to get
soiled or wipe it with a liquid.
Do not shock or cause an impact to the
intrusion sensor or the intrusion sensor
bezel.
 Do not install seats that are not Mazda
genuine products.
 To prevent obstruction of intrusion
sensor, do not place objects or cargo
near the intrusion sensor that are higher
than the head restraints.

Floor Mat
We recommend the use of Genuine
Mazda floor mats.
WA R N I N G
Make sure the floor mats are secured with
the grommets or the retainers to prevent
them from bunching up under the foot
pedals (Driver's side):
Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation
(driver's side), which could result in an
accident.
Only use a floor mat which conforms to the
shape of the floor on the driver's side and
make sure it is oriented correctly.
Secure the floor mat using the grommets or
retainers.
There are various ways to secure floor mats
depending on the type used, therefore
secure the mat according to the type.
After installing the floor mat, make sure
that it does not slide from side to side or
back and forth, and that there is sufficient
clearance with the accelerator and brake
pedals on the driver's side.
After removing the floor mat for cleaning
or some other reason, always securely
reinstall it while paying attention to the
precautions just mentioned.
Do not install two floor mats, one on top of
the other, on the driver's side:
Installing two floor mats, one on top of the
other, on the driver's side is dangerous as
the retention pins can only keep one floor
mat from sliding forward.
Loose floor mat(s) will interfere with the
foot pedals and could result in an accident.
If using an all-weather mat for winter use
always remove the original floor mat.
When setting a floor mat, position the
floor mat so that its g rommets or retainers
are inserted over th e pointed end of the
retention posts.
