Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System *
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 cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights on page 4-33 .
Refer to Tire Infl ation Pressure Warning Beep on page 7-42 .

The tire pressure sensors installed on each wheel send tire pressure dat\
a 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.

When Driving
Tire Pressure Monitoring System
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and infl ated to the infl ation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire infl ation pressure label. (If your vehicle has tires of a diff erent size than the
size indicated on the vehicle placard or tire infl ation pressure label, you should determine
the proper tire infl ation 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 signifi cantly under-infl ated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and infl ate them to the proper
pressure. Driving on a signifi cantly under-infl ated tire causes the tire to overheat and can
lead to tire failure. Under-infl ation also reduces fuel effi ciency and tire tread life, and may
aff ect 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-infl ation 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 fl ash 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 defl ation or blow out.

System Error Activation
When the warning light fl ashes, 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 non-
genuine 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
When an Authorized Mazda Dealer
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.

When Driving
Tire Pressure Monitoring System
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, switch the ignition ON, then back to ACC or
OFF.
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 fl ash
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
 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.
 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.

(Turns on)
Tire Pressure Monitoring System Warning Light
* When the warning light illuminates, and
the warning beep sound is heard when tire
pressure is too low in one or more tires.
WARNING
If the tire pressure monitoring system
warning light illuminates or fl
ashes,
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 fl ashes,
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 fl at, 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. Inspect the tires and adjust to the speci
fi ed
infl ation pressure (page 6-39 ).
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 in fl ation
pressure, the TPMS warning light/beep may turn
on after the tires cool and pressure drops below
specifi cation.
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 fl at. However, when you fi nd 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 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 re fi lling
the trouble tire as leaks are dangerous — take it
to an Authorized Mazda Dealer which has all the
equipment to fi x 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.
