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 Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-36.
Refer to Taking Action on page 7-40.
Refer to Tire Inflation Pressure Warning Beep on page 7-50.

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 illumina te 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.

▼System 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:
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 sidewalls.
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 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 flash
because the sensor ID signal code would
not have been registered. If this happens,
park the vehicle fo r 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.

4. Set the fan control dial to the desiredspeed.
5. If dehumidified heating is desired, turn
on the air conditioner.
NOTE
If the windshield fogs up easily, set the
mode selector dial to the
position.
If cooler air is desired at face level, set
the mode selector dial at the
position
and adjust the temperature control dial
to maintain maximum comfort.
The air to the floor is warmer than air
to the face (except wh en the temperature
control dial is set at the extreme hot or
cold position).
▼ Cooling
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the
cold position.
3. Set the fan control dial to the desired speed.
4. Turn on the air conditioner by pressing the A/C switch.
5. After cooling begins, adjust the fan control dial and temperature control
dial as needed to maintain maximum
comfort.
CAUTION
If the air conditioner is used while driving
up long hills or in heavy traffic, monitor the
high engine coolant temperature warning
indication/warning light to see if it is
illuminated or flashing (page 7-33).
The air conditioner may cause engine
overheating. If the warning light is
illuminated or flashing, turn the air
conditioner off (page 7-27).
NOTE
When maximum cooling is desired, set
the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then turn the fan control dial
fully clockwise.
If warmer air is desired at floor level,
set the mode selector dial at the
position and adjust the temperature
control dial to maintain maximum
comfort.

Noise may occur on the audio playback
depending on the device connected to
the accessory socket.
 Depending on the device connected to
the accessory socket, the vehicle's
electrical system may be affected, which
could cause the warning light to
illuminate. Disconnect the connected
device and make sure that the problem is
resolved. If the problem is resolved,
disconnect the device from the socket
and switch the ignition off. If the problem
is not resolved, consult an Authorized
Mazda Dealer.
NOTE
To prevent discharging of the battery, do
not use the socket for long periods with the
engine off or idling.

Washer Fluid
▼Inspecting Washer Fluid Level
WA R N I N G
Use only windshield washer fluid or plain
water in the reservoir:
Using radiator antifreeze as washer fluid is
dangerous. If sprayed on the windshield, it
will dirty the windshield, affect your
visibility, and could result in an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather:
Operating your vehicle in temperatures
below 4 °C (40 °F) using washer fluid
without anti-freeze protection is dangerous
as it could cause impaired windshield
vision and result in an accident. In cold
weather, always use washer fluid with
anti-freeze protection.
NOTE
State or local regulations may restrict the
use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides adequate
freeze resistance for all regions and
climates in which the vehicle will be
operated.
Add washer fluid under any of the
following conditions.
The top of the fluid level is low.
The Low Washer Fluid Level Warning
Indication/Warning Light (if equipped)
turns on.
The top of the fluid level is lower than E
(if equipped).

Use plain water if washer fluid is
unavailable.
But use only washer flu
id in cold weather
to prevent it from freezing.
