Driving Your Mazda Starting and Driving l l l l l l l When a metallic device such as a nongenuine 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 side walls. When using tire chains. l l 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. 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. When changing tires yourself If you or someone else changes tires, you or someone else can also undertake the steps for the TPMS to complete the ID signal code registration. 1. After tires have been changed, turn the ignition switch to the ON position, then turn it back to the ACC or LOCK position. 2. Wait for about 15 minutes. 3. After about 15 minutes, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10 minutes and the tire pressure sensor ID signal code will be registered automatically. NOTE If the vehicle is driven within about 15 minutes of changing tires, the tire pressure monitoring system warning light will flash because the sensor ID signal code would not have been registered. If this happens, park the vehicle for about 15 minutes, after which the sensor ID signal code will register upon driving the vehicle for 10 minutes. 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. 5-31
