When a tire pressure decreases

If the TPMS warning light turns on, a

tire pressure may be low. Inspect the

tire pressures and adjust them to the

correct in

fl

ation pressure.

Refer to Tire Pressure Monitoring

System (TPMS) Warning Indication/

Warning Light (Turns on) on page

7-37.

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 changing tires and wheels

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.

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.
1. Wait more than 19 minutes after

changing a tire or wheel.

2. After more than 19 minutes have

passed, drive the vehicle at a speed

of about 25 km/h (16 mph) or

faster for 3 minutes or longer. While

driving, the ID signal codes of the

tire pressure sensors are

automatically registered.

NOTE

If you drive the vehicle within 19

minutes of changing a tire or wheel,

the TPMS warning light will 

fl

ash

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.

When replacing tires and wheels

CAUTION



When replacing the tires and wheels,

consult an Authorized Mazda Dealer

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 replacing a tire or wheel, always

install the tire pressure sensor. The

following combinations of tires,

wheels, or tires and wheels are

possible.



The tire pressure sensor from the old

wheel is removed and it is installed

to the new wheel.



Only a tire is replaced without

replacing the tire pressure sensor and

wheel.



A new tire pressure sensor is installed

to a new wheel.
