Mazda 3 Sedan 2023 Tire Pressure Monitoring System User Manual
Introduction
The Tire Pressure Monitoring System (TPMS) is an important safety feature found in modern automobiles. It is intended to monitor tire air pressure and notify drivers if any tire’s pressure falls below the recommended level. Tire pressure is critical for optimal vehicle performance, fuel efficiency, and overall safety. Sensors mounted on each tire, typically within the valve stem or integrated with the tire’s inner structure, are used by the TPMS. These sensors continuously monitor tire pressure and send the information to a central control unit within the vehicle. The information is then analyzed by the control unit, which provides real-time feedback to the driver.
The primary function of the TPMS is to alert drivers to significant changes in tire pressure. Underinflated or overinflated tires can cause a variety of problems, including decreased traction, poor handling, longer braking distances, and uneven tire wear. The TPMS helps drivers maintain proper tire inflation levels and avoid potential road hazards by monitoring tire pressure. Because features and functionality vary between models and manufacturers, it’s critical to consult the owner’s manual for specific details and instructions regarding the TPMS system in your specific vehicle.
Tire Pressure Monitoring System (TPMS)
Tire Pressure Monitoring System (TPMS)
The TPMS monitors the air pressure of each tire and if it decreases below the specified value, the system notifies the driver by turning on the TPMS warning light in the instrument cluster and indicating a message on the multi-information display.
For the TPMS, the air pressure data sent from the tire pressure sensors installed on each wheel via radio signal is received by the receiver unit in the vehicle to monitor the tire pressures.
Tire pressure sensors
In addition, the current tire pressures can be checked using the center display.
Refer to the Vehicle Status Monitor section in the Mazda Connect Owner’s Manual.
NOTE
- When the ambient temperature is low, the tire temperatures also decrease. If the tire temperatures decrease, the air pressure in the tires will also decrease which could turn on the TPMS warning light.
- Before driving, visually inspect the tires for abnormalities. Additionally, inspect the tire pressures monthly. A digital type air pressure gauge is recommended for inspecting the tire pressures.
The TPMS is not a substitute for your own periodic inspection of the tires. Always inspect the tires yourself periodically.
CAUTION
- Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. - Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. - To avoid false readings, the system samples for a little while before indicating a problem. As a result it will not instantaneously register a rapid tire deflation or blow out.
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)
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)
Tires and Wheels
CAUTION
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.
NOTE
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.
- Wait more than 19 minutes after changing a tire or wheel.
- 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.
NOTE
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
CAUTION
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.
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.
NOTE
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.
FAQs
TPMS is an abbreviation for Tire Pressure Monitoring System. It is a vehicle feature that monitors tire air pressure and alerts the driver if it falls below a certain level.
Tire pressure monitoring systems (TPMS) are essential for safe driving, optimal vehicle performance, fuel efficiency, and tire longevity. TPMS assists drivers in maintaining proper tire pressure levels.
Tire pressure monitoring systems (TPMS) typically use sensors mounted on each tire to continuously monitor tire pressure. These sensors send data to a central control unit, which alerts the driver if any of the tires’ pressures fall below the recommended level.
TPMS is required in many countries and is found in the majority of modern vehicles manufactured after the early 2000s. Availability, however, may vary depending on the specific make, model, and trim level.
The TPMS warns the driver via a warning light on the dashboard. When the pressure in a tire falls below the recommended level, the warning light illuminates to indicate which tire needs attention.
If the TPMS warning light illuminates, manually check the tire pressure with a tire pressure gauge and inflate or adjust the tire pressure as needed.
In most cases, TPMS sensors can be replaced if they become damaged or malfunction. Repairs, on the other hand, are determined by the severity of the problem and the manufacturer’s specifications.
Yes, after adjusting tire pressure, most TPMS systems require a reset procedure. This is usually accomplished through the use of a reset button or a specific sequence of actions outlined in the owner’s manual for the vehicle.
Temperature changes can have an effect on TPMS sensors. Extreme cold or heat can cause tire pressure fluctuations, triggering TPMS warnings.
TPMS sensors are typically accurate to a few psi (pounds per square inch) within a certain range. They may not, however, provide precise readings like a dedicated tire pressure gauge.
Tire pressure monitoring systems (TPMS) are primarily intended to monitor tire pressure and may not detect specific tire damage or punctures. Visual inspections and routine maintenance are still required.
While TPMS is an additional safety tool, regular manual tire pressure checks with a gauge are still recommended to ensure accuracy and identify any issues that TPMS does not detect
Aftermarket wheels and tires may necessitate TPMS sensor recalibration or compatibility changes. To ensure proper functionality, it is critical to consult with a professional.
Most TPMS systems do not monitor the spare tire. Some vehicles with a full-size spare tire, on the other hand, may have a separate TPMS sensor for the spare.
In many countries, TPMS is a mandatory safety feature that cannot be permanently disabled. Some vehicles, however, may have a temporary disablement option for specific circumstances, as outlined in the owner’s manual.
