Mazda CX-3: Tire Pressure Monitoring System / System Error Activation

When the warning light flashes, there may be a system malfunction. Consult an Authorized Mazda Dealer.

A system error activation may occur in the following cases:

• When there is equipment or a device near the vehicle using the same radio frequency as that of the tire pressure sensors.
• When a metallic device such as a non-genuine navigation system is equipped near the center of the dashboard, which may block radio signals from the tire pressure sensor to the receiver unit.
• When using the following devices in the vehicle that may cause radio interference with the receiver unit.
  • A digital device such as a personal computer.
  • A current converter device such as a DC-AC converter.
• When excess snow or ice adheres to the vehicle, especially around the wheels.
• When the tire pressure sensor batteries are exhausted.
• When using a wheel with no tire pressure sensor installed.
• When using tires with steel wire reinforcement in the sidewalls.
• When using tire chains.
