When Driving -> Tire Pressure Monitoring System (TPMS) for Your Mazda CX-30 SUV 2020

When Driving  
Tire Pressure Monitoring System (TPMS)  
Before driving, visually inspect the  
Tire Pressure Monitoring  
tires for abnormalities. Additionally,  
inspect the tire pressures monthly. A  
digital type air pressure gauge is  
recommended for inspecting the tire  
pressures.

Tire Pressure Monitoring System  
(TPMS)  
The TPMS monitors the air pressure of  
each tire and if it decreases below the  
specified value, the system notifies the  
driver by turning on the TPMS warning  
light in the instrument cluster and  
indicating a message on the

multi-information display.  
Each tire, including the spare (if  
provided), should be checked  
monthly when cold and inflated to  
the inflation pressure recommended  
by the vehicle manufacturer on the  
vehicle placard or tire inflation  
pressure label. (If your vehicle has  
tires of a different size than the size  
indicated on the vehicle placard or  
tire inflation pressure label, you  
should determine the proper tire  
inflation pressure for those tires.)  
As an added safety feature, your  
vehicle has been equipped with a  
tire pressure monitoring system  
(TPMS) that illuminates a low tire  
pressure telltale when one or more  
of your tires is significantly  
For the TPMS, the air pressure data  
sent from the tire pressure sensors  
installed on each wheel via radio signal  
is received by the receiver unit in the  
vehicle to monitor the tire pressures.

under-inflated. Accordingly, when  
the low tire pressure telltale  
illuminates, you should stop and  
check your tires as soon as possible,  
and inflate them to the proper  
pressure. Driving on a significantly  
under-inflated tire causes the tire to  
overheat and can lead to tire failure.  
Under-inflation also reduces fuel  
efficiency and tire tread life, and may  
affect the vehicle's handling and  
stopping ability.  
NOTE  
When the ambient temperature is  
low, the tire temperatures also  
decrease. If the tire temperatures  
decrease, the air pressure in the tires  
will also decrease which could turn  
on the TPMS warning light.

maintenance, and it is the driver's  
responsibility to maintain correct tire  
pressure, even if under-inflation has  
not reached the level to trigger  
illumination of the TPMS low tire  
pressure telltale.  
Your vehicle has also been equipped  
with a TPMS malfunction indicator to  
indicate when the system is not  
operating properly.  
The TPMS malfunction indicator is  
combined with the low tire pressure  
telltale. When the system detects a  
malfunction, the telltale will flash for  
approximately one minute and then  
remain continuously illuminated.  
This sequence will continue upon  
subsequent vehicle start-ups as long  
as the malfunction exists. When the  
malfunction indicator is illuminated,  
the system may not be able to detect  
or signal low tire pressure as  
If the TPMS warning light flashes, there  
may be a problem with the system.  
Consult an Authorized Mazda Dealer  
to have the system inspected.

In the following cases, the system  
cannot recognize the tire pressures  
correctly and the TPMS warning light  
may flash.

Always check the TPMS malfunction

tires or wheels on your vehicle to  
ensure that the replacement or  
alternate tires and wheels allow the  
TPMS to continue to function  
properly.  
To avoid false readings, the system  
samples for a little while before

If you drive the vehicle within 19  
minutes of changing a tire or wheel,  
the TPMS warning light will flash  
because the ID signal codes for the tire  
pressure sensors were not registered.  
In this case, stop the vehicle and  
register the ID signal codes of the tire  
pressure sensors following the  
procedure.  
Tires and Wheels  
CAUTION  
When inspecting/adjusting the tire  
pressures, do not apply excessive force  
to the air valve of the tire pressure  
sensor. Otherwise, the tire pressure  
sensor could be damaged.  
When replacing tires and wheels

Otherwise, the tire pressure sensors  
could be damaged when replacing  
them.  
Do not install non-genuine wheels. If  
wheels other than genuine ones are  
installed, it may not be possible to  
install the tire pressure sensors.  
When changing the tires or wheels  
(such as installing winter tires), it will  
be necessary to register the ID signal  
code of the tire pressure sensor to the  
TPMS.  
Have an Authorized Mazda Dealer do  
the registration or register the ID signal  
codes of the tire pressure sensors using  
the following procedure.  
When replacing a tire or wheel, always  
install the tire pressure sensor. The  
following combinations of tires,  
wheels, or tires and wheels are  
possible.  
NOTE  
The tire pressure sensors on each  
wheel have a unique ID signal code.  
For the TPMS to operate correctly, the  
ID signal codes of the tire pressure  
sensors need to be registered to the  
system.
