Tyre Pressure Monitoring System
Tyre Pressure Monitoring System (Some Models)
The Tyre Pressure Monitoring System (TPMS) monitors the pressure for each tyre.
If tyre pressure is too low in one or more tyres, the system will inform the driver via the warning light in the instrument cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights (Search).
Refer to Tyre Inflation Pressure Warning Beep (Search).
The tyre pressure sensors installed on each wheel send tyre pressure data by radio signal to the receiver unit in the vehicle.
When the ambient temperature is low due to seasonal changes, tyre temperatures are also lower. When the tyre temperature decreases, the air pressure decreases as well. The TPMS warning light may illuminate more frequently. Visually inspect the tyres daily before driving, and check tyre pressures monthly with a tyre pressure gauge. When checking tyre pressures, use of a digital tyre pressure gauge is recommended.
TPMS does not alleviate your need to check the pressure and condition of all four tyres regularly.
-
Each tyre, 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 tyre inflation pressure label. (If your vehicle has tyres of a different size than the size indicated on the vehicle placard or tyre inflation pressure label, you should determine the proper tyre inflation pressure for those tyres.)
As an added safety feature, your vehicle has been equipped with a tyre pressure monitoring system (TPMS) that illuminates a low tyre pressure telltale when one or more of your tyres is significantly under-inflated. Accordingly, when the low tyre pressure telltale illuminates, you should stop and check your tyres as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tyre causes the tyre to overheat and can lead to tyre failure. Under-inflation also reduces fuel efficiency and tyre tread life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the driver's responsibility to maintain correct tyre pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tyre 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 tyre 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 tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tyres or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tyres or wheels on your vehicle to ensure that the replacement or alternate tyres 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 tyre deflation or blow out.
System Error Activation
When the warning light flashes, there may be a system malfunction. Consult an Authorised 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 tyre pressure sensors.
-
When a metallic device such as a non-genuine navigation system is equipped near the centre of the instrument panel, which may block radio signals from the tyre 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 tyre pressure sensor batteries are exhausted.
-
When using a wheel with no tyre pressure sensor installed.
-
When using tyres with steel wire reinforcement in the side walls.
-
When using tyre chains.
Tyres and Wheels
When inspecting or adjusting the tyre air pressures, do not apply excessive force to the stem part of the wheel unit. The stem part could be damaged.
Changing tyres and wheels
The following procedure allows the TPMS to recognise a tyre pressure sensor's unique ID signal code whenever tyres or wheels are changed, such as changing to and from winter tyres.
Each tyre 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 Authorised Mazda Dealer change your tyre and complete ID signal code registration.
When having tyres changed at an Authorised Mazda Dealer
When an Authorised Mazda Dealer changes your vehicle's tyres, they will complete the tyre pressure sensor ID signal code registration.
When changing tyres yourself
If you or someone else changes tyres, you or someone else can also undertake the steps for the TPMS to complete the ID signal code registration.
-
After tyres have been changed, switch the ignition ON, then back to ACC or OFF.
-
Wait for about 15 minutes.
-
After about 15 minutes, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10 minutes and the tyre pressure sensor ID signal code will be registered automatically.
If the vehicle is driven within about 15 minutes of changing tyres, the tyre 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.
Replacing tyres and wheels
-
When replacing/repairing the tyres or wheels or both, have the work done by an Authorised Mazda Dealer, or the tyre pressure sensors may be damaged.
-
The wheels equipped on your Mazda are specially designed for installation of the tyre pressure sensors. Do not use non-genuine wheels, otherwise it may not be possible to install the tyre pressure sensors.
Be sure to have the tyre pressure sensors installed whenever tyres or wheels are replaced.
When having a tyre or wheel or both replaced, the following types of tyre pressure sensor installations are possible.
-
The tyre pressure sensor is removed from the old wheel and installed to the new one.
-
The same tyre pressure sensor is used with the same wheel. Only the tyre is replaced.
-
A new tyre pressure sensor is installed to a new wheel.
-
The tyre pressure sensor ID signal code must be registered when a new tyre pressure sensor is purchased. For purchase of a tyre pressure sensor and registration of the tyre pressure sensor ID signal code, consult an Authorised Mazda Dealer.
-
When reinstalling a previously removed tyre pressure sensor to a wheel, replace the grommet (seal between valve body/sensor and wheel) for the tyre pressure sensor.
