4–142
When Driving
Tyre Pressure Monitoring System
NOTE
Because this system detects slight changes in tyre conditions, the timing of the warning
may be faster or slower in the following cases:
 
 The size, manufacturer, or the type of tyres is different from the speci¿ cation. 
 The size, manufacturer, or the type of a tyre is different from the others, or the level of
tyre wear is excessively different between them.
  A run-À at tyre, studless tyre, snow tyre, or tyre chains are used. 
 An emergency tyre is used (The tyre pressure monitoring system warning light may
À ash and then continue illuminating).

 A tyre is repaired using the emergency À at tyre repair kit. 
 The tyre pressure is excessively higher than the speci¿ ed pressure, or the tyre pressure
is suddenly lowered for some reason such as a tyre burst during driving.
  The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle
is stopped), or the drive period is shorter than 5 minutes.
  The vehicle is driven on an extremely rough road or a slippery, icy road. 
 Hard steering and rapid acceleration/deceleration are repeated such as during
aggressive driving on a winding road.
  Load on the vehicle is applied to a tyre such as by loading heavy luggage to one side of
the vehicle.
  System initialization has not been implemented with the speci¿ ed tyre pressure.

When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
 


 A tyre pressure is adjusted.



 Tyre rotation is performed.



 A tyre or wheel is replaced.



 The battery is replaced or completely
drained.
 


 The tyre pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe place and ¿ rmly
apply the parking brake.
2. Let the tyres cool, then adjust the tyre
pressure of all four (4) tyres to the
speci¿ ed pressure indicated on the tyre
pressure label located on the driver's
door frame (door open).
Refer to Tyres on page 9-8 .
3. Switch the ignition ON.
4. Press and hold the tyre pressure
monitoring system set switch and
verify that the tyre pressure monitoring
system warning light in the instrument
clusterÀ ashes twice and a beep sound
is heard once.
CAUTION
If the system initialization is performed
without adjusting the tyre pressure, the
system cannot detect the normal tyre
pressure and it may not illuminate the
tyre pressure monitoring system warning
light even if a tyre pressure is low, or
it may illuminate the light even if the
pressures are normal.
Adjust the tyre pressure on all four
tyres and initialize the system when
the warning light is turned on. If the
warning light turns on for a reason other
than a À at tyre, the tyre pressure of all
four tyres may have decreased naturally.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.

When Driving
Tyre Pressure Monitoring System
*Some models.
Tyre Pressure Monitoring System (Vehicle with Run-À at
Ty r e s )
*
The Tyre Pressure Monitoring System (TPMS) monitors the pressure for each tyre.
If tyre pressure is too low in one or more tyres, 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 4-42 .
Refer to Tyre InÀ ation Pressure Warning Beep on page 7-53 .
The tyre pressure sensors installed on each wheel send tyre pressure data by radio signal to
the receiver unit in the vehicle.
Tyre pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tyre temperatures are also
lower. When the tyre temperature decreases, the air pressure decreases as well. The TPMS
warning light may illuminate more frequently. Visually inspect the tyres daily before
driving, and check tyre pressures monthly with a tyre pressure gauge. When checking tyre
pressures, use of a digital tyre pressure gauge is recommended.
TPMS does not alleviate your need to check the pressure and condition of all four tyres
regularly.

When Driving
Tyre Pressure Monitoring System
System Error Activation
When the TPMS warning light À ashes,
there may be a system malfunction.
Consult an Authorised 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 tyre pressure
sensors.
 


 When a metallic device such as a non-
genuine navigation system is equipped
near the centre of the instrument panel,
which may block radio signals from the
tyre 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 tyre pressure sensor batteries
are exhausted.
 


 When using a wheel with no tyre
pressure sensor installed.
 


 When using tyres with steel wire
reinforcement in the side walls.
 


 When using tyre chains.
Tyres and Wheels
CAUTION
When inspecting or adjusting the tyre air
pressures, do not apply excessive force
to the stem part of the wheel unit. The
stem part could be damaged.
Changing tyres and wheels
The following procedure allows the TPMS
to recognise a tyre pressure sensor's
unique ID signal code whenever tyres or
wheels are changed, such as changing to
and from winter tyres.
NOTE
Each tyre 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 Authorised Mazda Dealer change
your tyre and complete ID signal code
registration.
When having tyres changed at an
Authorised Mazda Dealer
When an Authorised Mazda Dealer
changes your vehicle's tyres, they will
complete the tyre pressure sensor ID signal
code registration.
When changing tyres yourself
If you or someone else changes tyres, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.

When Driving
Tyre Pressure Monitoring System
1. After tyres 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 tyre
pressure sensor ID signal code will be
registered automatically.
NOTE
If the vehicle is driven within about
15 minutes of changing tyres, the tyre
pressure monitoring system warning
light will À 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 tyres and wheels
CAUTION
  When replacing/repairing the tyres or
wheels or both, have the work done
by an Authorised Mazda Dealer, or
the tyre pressure sensors may be
damaged.
  The wheels equipped on your Mazda
are specially designed for installation
of the tyre pressure sensors. Do not
use non-genuine wheels, otherwise it
may not be possible to install the tyre
pressure sensors. Be sure to have the tyre pressure sensors
installed whenever tyres or wheels are
replaced.
When having a tyre or wheel or both
replaced, the following types of tyre
pressure sensor installations are possible.
 


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


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


 A new tyre pressure sensor is installed to
a new wheel.
NOTE
  The tyre pressure sensor ID signal
code must be registered when a new
tyre pressure sensor is purchased. For
purchase of a tyre pressure sensor
and registration of the tyre pressure
sensor ID signal code, consult an
Authorised Mazda Dealer.
  When reinstalling a previously
removed tyre pressure sensor to a
wheel, replace the grommet (seal
between valve body/sensor and
wheel) for the tyre pressure sensor.

When Driving
Parking Sensor System
*Some models.
Parking Sensor System *
The parking sensor system uses ultrasonic sensors to detect obstructions around the vehicle
while parking the vehicle in a garage or during parallel parking when the shift lever (manual
transmission)/selector lever (automatic transmission) is in reverse (R). The system is
equipped with an assist device to notify the driver of the approximate distance from the
vehicle to the surrounding obstruction using a beep sound.

WARNING
Do not rely completely on the parking sensor system and be sure to con¿ rm the safety
around your vehicle visually when driving.
This system can assist the driver in operating the vehicle in the backward directions
while parking. The detection ranges of the sensors are limited, therefore, driving the
vehicle while relying only on the system may cause an accident. Always con¿ rm the
safety around your vehicle visually when driving.
