When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System *
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-164 .
The warning light fl ashes when the system has a malfunction.

When Driving
Tyre Pressure Monitoring System
CAUTION
  Each tyre, 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 tyre infl ation pressure label. (If your vehicle has tyres of a different
size than the size indicated on the vehicle placard or tyre infl ation pressure label, you
should determine the proper tyre infl ation pressure for those tyres.)
 As an added safety feature, your vehicle has been equipped with a tyre pressure
monitoring system (TPMS) that illuminates a low tyre pressure telltale when one or
more of your tyres is signifi cantly under-infl ated. Accordingly, when the low tyre
pressure telltale illuminates, you should stop and check your tyres as soon as possible,
and infl ate them to the proper pressure. Driving on a signifi cantly under-infl ated tyre
causes the tyre to overheat and can lead to tyre failure. Under-infl ation also reduces
fuel effi ciency and tyre tread life, and may affect the vehicle's handling and stopping
ability.
 Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the
driver's responsibility to maintain correct tyre pressure, even if under-infl ation has not
reached the level to trigger illumination of the TPMS low tyre 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 tyre 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 tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tyres or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tyres or wheels on your vehicle to ensure that the
replacement or alternate tyres 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 tyre defl ation or blow
out.

Monitoring System
Warning Light
*
If the tyre pressure monitoring system has a malfunction, the tyre pressure warning
light fl ashes for about 1 minute when the ignition is switched ON and then continues
illuminating. Have your vehicle checked by an expert repairer, we recommend an
Authorised Mazda Repairer as soon as possible.
WARNING

If the tyre pressure monitoring system warning light illuminates or fl ashes, or the
tyre pressure warning beep sound is heard, decrease vehicle speed immediately and
avoid sudden manoeuvring and braking:
If the tyre pressure monitoring system warning light illuminates or fl ashes, or the
tyre pressure warning beep sound is heard, it is dangerous to drive the vehicle at high
speeds, or perform sudden manoeuvring 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 tyre and determine if you have enough air
to proceed to a place where air may be added and the system monitored again by
an expert repairer, we recommend an Authorised Mazda Repairer or a tyre 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 tyre failure and a dangerous accident.

(Illuminate)
KEY Warning Light If any malfunction occurs in the keyless entry system, it illuminates continuously.
CAUTION
If the key warning indicator light illuminates or the push button start indicator light
(amber) fl ashes, the engine may not start. If the engine cannot be started, try starting it
using the emergency operation for starting the engine, and have the vehicle inspected at
an expert repairer, we recommend an Authorised Mazda Repairer as soon as possible.

When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), tyre pressure is too low in one or
more tyres.
WARNING
If the tyre pressure monitoring system
warning light illuminates or fl ashes,
or the tyre pressure warning beep
sound is heard, decrease vehicle
speed immediately and avoid sudden
manoeuvring and braking:
If the tyre pressure monitoring system
warning light illuminates or fl ashes, or
the tyre pressure warning beep sound
is heard, it is dangerous to drive the
vehicle at high speeds, or perform
sudden manoeuvring or braking.
Vehicle drivability could worsen and
result in an accident.
To determine if you have a slow leak or
afl at, pull over to a safe position where
you can check the visual condition
of the tyre and determine if you have
enough air to proceed to a place where
air may be added and the system
monitored again by an expert repairer,
we recommend an Authorised Mazda
Repairer or a tyre 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 tyre failure and a
dangerous accident. Inspect the tyres and adjust to the specifi ed
infl ation pressure (page 6-46 ).
NOTE
Perform tyre pressure adjustment when
the tyres are cold. Tyre pressure will
vary according to the tyre temperature,
therefore let the vehicle stand for 1
hour or only drive it 1.6 km (1 mile) or
less before adjusting the tyre pressures.
When pressure is adjusted on hot
tyres to the cold infl ation pressure, the
TPMS warning light/beep may turn on
after the tyres cool and pressure drops
below specifi cation.
Also, an illuminated TPMS warning
light, resulting from the tyre air
pressure dropping due to cold ambient
temperature will remain illuminated
even if the ambient temperature rises.
In this case, it will also be necessary
to adjust the tyre air pressures. If the
TPMS warning light illuminates due
to a drop in tyre air pressure, make
sure to check and adjust the tyre air
pressures.
Tyres lose air naturally over time
and the TPMS cannot tell if the tyres
are getting too soft over time or you
have a fl at. However, when you fi nd
one low tyre 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
tyre 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 reinfl ating the tyre
as leaks are dangerous — take it to
an expert repairer, we recommend an
Authorised Mazda Repairer.
