Driving Your Mazda Starting and Driving If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture. Replace the punctured tire with the temporary spare tire (page 7-8). NOTE A tire pressure sensor is not installed to the temporary spare tire. The warning light will flash continuously while the temporary spare tire is being used. qTires and Wheels CAUTION When inspecting or adjusting the tire air pressures, do not apply excessive force to the stem part of the wheel unit. The stem part could be damaged. Changing tires and wheels The following procedure allows the TPMS to recognize a tire pressure sensor's unique ID signal code whenever tires or wheels are changed, such as changing to and from winter tires. NOTE Each tire pressure sensor has a unique ID signal code. The signal code must be registered with the TPMS before it can work. The easiest way to do it is to have an Authorized Mazda Dealer change your tire and complete ID signal code registration. Warning light flashes When the warning light flashes, there may be a system malfunction. Consult an Authorized Mazda Dealer. qSystem Error Activation When the TPMS warning light flashes, there may be a system malfunction. Consult an Authorized Mazda Dealer. A system error activation may occur in the following cases: l When there is equipment or a device near the vehicle using the same radio frequency as that of the tire pressure sensors. l 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. l When excess snow or ice adheres to the vehicle, especially around the wheels. l When the tire pressure sensor batteries are exhausted. l When using a wheel with no tire pressure sensor installed. l When using tires with steel wire reinforcement in the side walls. l When using tire chains. l l When having tires changed at an Authorized Mazda Dealer Tire pressure sensor ID signal code registration is completed when an Authorized Mazda Dealer changes your vehicle's tires.
