Tire Pressure Monitoring System

The tire pressure monitoring system (TPMS) monitors the pressure for each


The tire pressure monitoring system (TPMS) monitors the pressure for each tire.

If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument panel and by the warning beep sound.

The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.

NOTE:
When the ambient temperature is low due to seasonal changes, tire temperatures are also lower.

When the tire temperature decreases, the air pressure decreases as well. The TPMS warning light
may illuminate more frequently. Visually inspect the tires daily before driving, and check tire
pressures monthly with a tire pressure gauge. When checking tire pressures, use of a digital tire
pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.

CAUTION:
cold 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 underinflated
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 underinflation
has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

indicate when the system is not operating properly. 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.

indicating a
problem. As a result it will not instantaneously register a rapid tire deflation or
blow out.

Tire Pressure Monitoring System Warning Light

This warning light illuminates for a few


This warning light illuminates for a few seconds when the ignition switch is turned to the ON position.

Thereafter, the warning light illuminates and a beep is heard when tire pressure is too low in one or more tires, and flashes when there is a system malfunction.

WARNING:
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound is heard, decrease vehicle speed immediately and avoid sudden maneuvering and braking: If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound is heard, it is dangerous to drive the vehicle at high speeds, or perform sudden maneuvering or braking. Vehicle drivability could worsen and result in an accident.

To determine if you have a slow leak or a flat, pull over to a safe position where you can check the visual condition of the tire and determine if you have enough air to proceed to a place where air may be added and the system monitored again by an Authorized Mazda Dealer or a tire repair station.

Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated. Have the problem taken care of as soon as possible before it develops into a more serious situation that could lead to tire failure and a dangerous accident.

Warning light illuminates/Warning beep sounds

When the warning light illuminates, and the warning beep sound is heard (about 3 seconds), tire pressure is too low in one or more tires.

Adjust the tire pressure to the correct tire pressure. Refer to the specification charts.

CAUTION:
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the tire pressure sensors may be damaged.

NOTE:
- Perform tire pressure adjustment when the tires are cold. Tire pressure will vary according to the tire temperature, therefore let the vehicle stand for 1 hour or only drive it 1.6 km (1 mile) or less before adjusting the tire pressures. When pressure is adjusted on hot tires to the cold inflation pressure, the TPMS warning light/beep may turn on after the tires cool and pressure drops below specification.

Also, an illuminated TPMS warning light, resulting from the tire air pressure dropping due to cold ambient temperature, may turn off if the ambient temperature rises. In this case, it will also be necessary to adjust the tire air pressures. If the TPMS warning light illuminates due to a drop in tire air pressure, make sure to check and adjust the tire air pressures.

- After adjusting the tire air pressures, it may require some time for the TPMS warning light to turn off. If the TPMS warning light remains illuminated, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10 minutes, and then verify that it turns off.

- Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over time or you have a flat. However, when you find one low tire in a set of fourthat is an indication of trouble; you should have someone drive the vehicle slowly forward so you can inspect any low tire for cuts and any metal objects sticking through tread or sidewall. Put a few drops of water in the valve stem to see if it bubbles indicating a bad valve. Leaks need to be addressed by more than simply refilling the trouble tire as leaks are dangerous - take it to an Authorized Mazda Dealer which has all the equipment to fix tires, TPMS systems and order the best replacement tire for your vehicle.

If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture.

Refer to Vehicle with run-flat tires on.

Vehicles with Instant Mobility System (IMS) emergency flat tire repair kit

If an emergency tire repair is needed, repair the punctured tire with the emergency flat tire repair kit.

CAUTION:
Do not use non-genuine tire sealant.

It may damage the tire pressure sensor.

Vehicles with optional temporary spare tire

If you have bought the optional temporary spare tire, replace the punctured tire with the temporary spare tire. Refer to the manufacturer's instructions.

Warning light flashes

When the warning light flashes, there may be a system malfunction. Consult an Authorized Mazda Dealer.

Flat TireWarning Light

This warning light illuminates for a few


This warning light illuminates for a few seconds when the ignition switch is turned to the ON position.

Warning light illuminates/Warning beep sounds

If the tire pressures decrease extremely after the TPMS warning light has illuminated, or if a tire is punctured, the flat tire warning light also illuminates, and a beep sound will be heard for approximately 30 seconds.

Refer to Vehicle with run-flat tires.

System 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:
- When there is equipment or a device near the vehicle using the same radio frequency as that of the tire pressure sensors.

- 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.

Tires 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.

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.

Replacing tires and wheels

CAUTION:
or wheels or both, have the work When replacing/repairing the tires
or wheels or both, have the work done by an Authorized Mazda Dealer, or the tire pressure sensors may be damaged.

Mazda are specially designed for The wheels equipped on your
Mazda are specially designed for installation of the tire pressure sensors. Do not use non-genuine wheels, otherwise it may not be possible to install the tire pressure sensors.

Be sure to have the tire pressure sensors installed whenever tires or wheels are replaced.

When having a tire or wheel or both replaced, the following types of tire pressure sensor installations are possible.

- The tire pressure sensor is removed from the old wheel and installed to the new one.

- The same tire pressure sensor is used with the same wheel. Only the tire is replaced.

- A new tire pressure sensor is installed to a new wheel.

NOTE:
- The tire pressure sensor ID signal code must be registered when a new tire pressure sensor is purchased. For purchase of a tire pressure sensor and registration of the tire pressure sensor ID signal code, consult an Authorized Mazda Dealer.

- When reinstalling a previously removed tire pressure sensor to a wheel, replace the grommet (seal between valve body/sensor and wheel) for the tire pressure sensor.
