Tire Pressure Monitoring Systemí
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.
Tire pressure sensors
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
ØEach 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.
ØYour 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.
ØTo 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.
NOTE
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-8).
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
lPerform 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 go
out 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.
lAfter adjusting the tire air pressures, it may
require some time for the TPMS warning
light to go out. 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 goes out.
lTires can loose a little air quite 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 four - that 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 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. Replace the
punctured tire with the temporary spare
tire (page 7-8).
NOTE
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used.
Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
qSystem Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in
the following cases:
lWhen there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
lWhen a large metallic object (e.g. a
large electric household appliance or a
desk-top computer) is placed on the
right side of the rear seat, which may
block radio signals from the tire
pressure sensor to the receiver unit.
lWhen using the following devices in
the vehicle that may cause radio
interference with the receiver unit.
lA digital device such as a personal
computer.
lA current converter device such as a
DC-AC converter.
lWhen excess snow or ice adheres to
the vehicle, especially around the
wheels.
lWhen the tire pressure sensor batteries
are exhausted.
lWhen using a wheel with no tire
pressure sensor installed.
lWhen using tires with steel wire
reinforcement in the side walls.
lWhen using tire chains.
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.
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
ØWhen 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.
ØThe 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.
lThe tire pressure sensor is removed
from the old wheel and installed to the
new one.
lThe same tire pressure sensor is used
with the same wheel. Only the tire is
replaced.
lA new tire pressure sensor is installed
to a new wheel.
NOTE
lThe 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.
lWhen 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.

NOTE
When the engine is jump-started to charge the
battery, uneven rpm occurs and the ABS
warning light comes on. This is due to a weak
battery, not a malfunction.
Recharge the battery.
qElectronic Brake Force
Distribution System Warningí
If the electronic brake force distribution
control unit determines that some
components are operating incorrectly, the
control unit may turn the brake system
warning light and the ABS warning light
on at the same time. The problem is likely
to be the electronic brake force
distribution system.
WARNING
Do not drive with both the ABS warning
light and brake warning light
illuminated. Have the vehicle towed to
an Authorized Mazda Dealer to have
the brakes inspected as soon as
possible:
Driving when the brake system
warning light and ABS warning light
are illuminated at the same time is
dangerous.
When both lights are illuminated, the
rear wheels could lock more quickly
in an emergency stop than under
normal circumstances.
qCharging System Warning Light
This warning light illuminates when the
ignition switch is turned to the ON
position and turns off when the engine is
started.
If the warning light illuminates while
driving, it indicates a malfunction of the
alternator or of the charging system.
Drive to the side of the road and park off
the right-of-way. Consult an Authorized
Mazda Dealer.
CAUTION
Don't continue driving when the
charging system warning light is
illuminated because the engine could
stop unexpectedly.
qEngine Oil Pressure Warning Light
This warning light illuminates when the
ignition switch is turned to the ON
position and turns off when the engine is
