inflation pressure MAZDA MODEL MX-5 MIATA 2019 Owners Manual

Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is to o 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 Pressu re Warning Beep on page 7-51.

The tire pressure sensors installed on each wheel send tire pre ssure 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 con dition of all four tires
regularly.
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in flation pressure label, you should determine
the proper tire inflation 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 pre ssure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when th e low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduce s fuel efficiency and tire tread life, and may
affect 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 ti re pressure, even if under-inflation 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 wi ll flash 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 th at 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 regi ster a rapid tire deflation or blow out.
▼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 pressu re 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
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-8) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always
inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-8.
Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly when the
tires are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tire wear.
Refer to the specification charts (page
9-8).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequen tly needs inflating,
have it inspected.

11. Insert the air compressor plug into theaccessory socket inside the vehicle and
switch the ignition to ACC.
Refer to Accessory Sockets on page
5-92.
Compressor
Compressor plug
CAUTION
When inserting the air compressor plug
into or removing it from the accessory
socket, make sure that the air
compressor switch is off. When turning
the air compressor on/off, use the air
compressor switch.
12. The sealant is injected into the tire
when the air compressor is switched
on. After the sealant is injected
completely, wait until the tire inflation
pressure increases to the specified tire
inflation pressure.
NOTE
The inflation pressure may increase to
about 300 kPa (3.1 kgf/cm
2, 3 bar, 43.5
psi) temporarily to inject the sealant
through the valve. Normally, the
inflation pressure decreases gradually
and it reaches the actual inflation
pressure after about 30 seconds.
WARNING
Never use the air compressor above 300
kPa (3.1 kgf/ c m
2, 3 bar, 43.5 psi):
Using the air compressor at an inflation
pressure above 300 kPa (3.1 kgf/cm
2, 3
bar, 43.5 psi) continuously is
dangerous. If the air compressor
overheats, hot air will be exhausted and
you could get burned.
NOTE
Check the tire inflation pressure
label driver's door frame for the
correct tire inflation pressure.
Do not operate the air compressor
for a continuous 10 minutes or
longer because using it for long
periods could cause a malfunction.
