Tire Pressure Monitoring System (TPMS)

If there is a problem with the Tire Pressure Monitoring System (TPMS)

If the TPMS warning light flashes, there may be a problem with the system. Consult an Authorized Mazda Dealer to have the system inspected.

Refer to Tire Pressure Monitoring System (TPMS) Warning Indication/Warning Light (Flashing) (Search).

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

  • There is equipment or a device nearby emitting radio signals the same as a tire pressure sensor.

  • A metallic object such as a non-genuine electronic device is installed near the center of the dashboard (obstructs the radio signals from the tire pressure sensors to the receiver).

  • A device such as one of the following is used in the cabin.

    • Electronic devices such as a computer.

    • Converter devices such as a DC-AC converter.

  • There is a large accumulation of snow or ice around the vehicle tires.

  • The battery in a tire pressure sensor is dead.

  • A wheel not equipped with a tire pressure sensor is used.

  • Tires employing steel in the sidewall of the tire are installed.

  • Tire chains are used.

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 inflation pressure.

Refer to Tire Pressure Monitoring System (TPMS) Warning Indication/Warning Light (Turns on) (Search).

Tires and Wheels

 

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.

 

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.

 

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.

When replacing tires and wheels

 

  • 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.

Close Caution

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.

 

When installing a new tire pressure sensor, the ID signal code for the tire pressure sensor needs to be registered. For details on purchasing a tire pressure sensor and registering the ID signal of the tire pressure sensor, consult an Authorized Mazda Dealer.
