Before Driving -> Security System for Your Mazda Cx-5 SUV 2023

Before Driving  
Security System  
Modification and Add-On  
Equipment  
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.  
Immobilizer System  
The immobilizer system allows the engine  
to start only with a key the system  
recognizes.  
If someone attempts to start the engine  
with an unrecognized key, the engine will  
not start, thereby helping to prevent  
vehicle theft.  
CAUTION  
If you have a problem with the  
immobilizer system or the key, consult an  
Authorized Mazda Dealer.  
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.  
CAUTION  
Radio equipment like this is governed by  
laws in the United States.  
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 dashboard or  
hood, 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 Authorized Mazda Dealer.

Before Driving  
Security System  
NOTE  
The security indicator light in the  
instrument cluster flashes every 2 seconds  
until the system is disarmed.  
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 Authorized  
Mazda Dealer.  
Always keep a spare key in case one is  
lost. If a key is lost, consult an  
Authorized Mazda Dealer as soon as  
possible.  
If you lose a key, an Authorized Mazda  
Dealer, will reset the electronic codes of  
your remaining keys and immobilizer  
system. Bring all the remaining keys to  
the Authorized Mazda Dealer to reset.  
Starting the vehicle with a key that has  
not been reset is not possible.  
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 does not start after 3  
or more tries, contact an Authorized  
Mazda Dealer.  
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 dashboard or in  
the glove compartment. 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.  
NOTE  
If the security indicator light flashes  
continuously while you are driving, do  
not shut off the engine. Go to an  
Authorized Mazda Dealer, 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 Authorized Mazda  
Dealer, so that they can be programmed.  
Arming  
The system is armed when the ignition is  
switched from ON to off.
