The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low or too high 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.
TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
Tire Pressure Monitoring
System*
Tire pressure sensors
•When the tire pressure monitoring
system warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper
pressure as indicated on the
vehicle’s tire information placard.
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. Each tire,
including the spare, should be
checked monthly when cold and set
to the recommended inflation
pressure as specified in the vehicle
placard and owner’s manual.
•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.
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.

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

2. Wait for about 15 minutes.
3. After about 15 minutes, drive the
vehicle at a speed of at least 20 km/h
(12 mph) for several minutes and the
tire pressure sensor ID signal code will
be registered automatically.
Replacing tires and wheelsBe 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 installation 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
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
several minutes.
•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.
CAUTION
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 for the
tire pressure sensor.

the spare tire can be installed. Before
removing the lug nuts, make sure your
Mazda is firmly in position and that it
cannot slip or move.
6. Remove the lug nuts by turning them
counterclockwise; then remove the
wheel and center cap.
Locking Lug Nuts*
If your vehicle has optional antitheft
wheel lug nuts, one on each wheel will
lock the tires and you must use a special
key to unlock them. This key is attached
to the lug wrench and is stored with the
spare tire. Register them with the lock
manufacturer by filling out the card
provided in the glove box and mailing it in
the accompanying envelope. If you lose
your key, consult an Authorized Mazda
Dealer or use the lock manufacturer’s
order form, which is with the registration
card.
To remove an antitheft lug nut
1. Get the key for the locking lug nut.
2. Place it on top of the nut, and be sure to
hold the key square to it. If you hold
the key at an angle, you may damage
both key and nut. Don’t use a power
impact wrench.
3. Place the lug wrench on top of the key
and apply pressure. Turn the wrench
counterclockwise.

To replace the nut
1. Place the key on top of the nut.
2. Place the lug wrench on top of the key,
apply pressure, and turn it clockwise.

Mounting the Spare Tire
1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.
2. Mount the spare tire.3. Install the lug nuts with the beveled
edge inward; tighten them by hand.
Removing Dirt and Grime from
Wheels, Hubs and Hub Bolts:
When changing or replacing a tire,
not removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident. Make sure the mounting
surfaces of the wheel, hub and lug
nuts are clean before changing or
replacing tires.
WARNING
Don’t Apply Oil or Grease to Lug
Nuts, Bolts:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the
tire to come off, resulting in an
accident. In addition, lug nuts and
bolts could be damaged if tightened
more than necessary. Do not apply oil
or grease to lug nuts and bolts and do
not tighten the lug nuts beyond the
recommended tightening torque.

4. Turn the jack handle counterclockwise
and lower the vehicle. Use the lug
wrench to tighten the nuts in the order
shown.
If you’re unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.
Nut tightening torque:

N·m (kgf·m, ft·lbf) 88—117 (9—11, 65—93)
Loose Lug Nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off. This could result
in loss of vehicle control and cause a
serious accident. Always securely and
correctly tighten the lug nuts.
Metric Studs and Lug Nuts:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip
off and cause an accident. Be sure to
reinstall the same nuts you removed
or replace them with metric nuts of
the same configuration.
Incorrect Tire Air Pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
Don’t drive with any tires that have
incorrect air pressure. When you
check the regular tires’ air pressure,
check the spare tire, too.
