M T D J u n e 2 0 1 8 72 T P M S SUBJECT VEHICLES: 2007 – 2014 Mazda3 and Mazda2 vehicles. RELEARN PROCEDURE? No. SPECIAL TOOLS NEEDED? An M-MDS scan tool may be used for the registration procedure. e tire pressure monitoring system (TPMS) on 2007 – 2014 Mazda3 and Mazda2 vehicles monitors the pressure for each tire. If tire pressure is too low or too high in one or more tires, the TPMS will turn on a warning light on the instrument panel and sound a warning beep for about 3 seconds. If there is a system malfunction or a spare tire is in use, the warning light will flash. Tire pressure sensors installed on each wheel send tire pressure data by radio signal to the receiver unit in the vehicle. is system may not function properly under the following conditions: • When there is equipment or a device near the vehicle using the same radio frequency as that of the tire pressure sensors. • When a large metallic object (i.e., a large electric house- hold appliance or a desktop computer) is placed on the right side of the rear seat, it may block radio signals from the tire pressure sensor to the receiver unit. • When using a digital device (such as a personal com- puter) or a current converter device that may cause radio interference with the receiver unit. • When excess snow or ice adheres to the vehicle. • When tire pressure sensor batteries are exhausted. • When using a wheel with no tire pressure sensor installed (i.e., a spare tire). • When using tires with steel wire reinforcement in the sidewalls or when using tire chains. TIRE PRESSURE MONITOR WARNING LIGHT CAUTION: Do not tilt or use excessive side force when checking air pressure or inflating a tire, or the tire pressure sensor may be damaged. When the tire pressure warning light illuminates and the warning beep sound is heard (about 3 seconds), check tire pressure and adjust as necessary. When pressure is adjusted on hot tires to the cold inflation pressure, the warning light/ beep may turn on aer the tires cool and pressure drops below specification. Also, an illuminated warning light resulting from the tire air pressure dropping due to cold ambient temperature may go out if the ambient temperature rises. In this case, it will also be necessary to adjust the tire air pressure. If the warning light illuminates again even aer the tire pressures are adjusted, the tire may be punctured. NOTE: Aer adjusting the tire air pressures, it may require some time for the warning light to go out. If the warning light remains illuminated, drive the vehicle at a speed of at least 16 mph (25 km/h) for 10 minutes, and then verify that it goes out. If the warning light is flashing and a spare tire is not in use, there is a malfunction in the TPMS. See the appropriate manufacturer service information. TPMS RESET PROCEDURES NOTE: Whenever tires or wheels are changed (including changing to and from winter tires) where a new sensor is installed, the tire pressure sensor's unique ID signal code must be registered with the TPMS. Tire pressure sensor ID registration is achieved automatically once the vehicle has been stationary for 15 minutes or more, and then driven at a speed of at least 16 mph (25 km/h) for 10 minutes or more. When the tire pressure warning light illuminates and the warning beep sound is heard, check tire pressure and adjust as necessary. Aer adjusting the tire air pressures, it may require some time for the warning light to go out. If the warning light remains illuminated, drive the vehicle at a speed of at least 16 mph (25 km/h) for 10 minutes, and then verify that it goes out. 2007 – 2014 Mazda3 and Mazda2 PHOTO COURTESY OF MAZDA
