warning light MAZDA MODEL MX-5 2020 Owners Manual (in English)

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 wi ll 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 Inspe cted on page 7-36.
Refer to Taking Action on page 7-40.
Refer to Tire Inflation Pressu re Warning Beep on page 7-50.

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.

▼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, switchthe ignition ON, then back to ACC or
O F F.
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 s ignal 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 ti re 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 sen sor 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.

Storage Compartments
WARNING
Keep storage boxes closed when driving:
Driving with the storage boxes open is
dangerous. To reduce the possibility of
injury in an accident or a sudden stop, keep
the storage boxes closed when driving.
Do not put articles in storage spaces with
no lid:
Putting articles in storage spaces with no
lid is dangerous as they could be thrown
around the cabin if th e vehicle is suddenly
accelerated and cause injury depending on
how the article is stored.
CAUTION
Do not leave lighters or eyeglasses in the
storage boxes while parked under the sun.
A lighter could explode or the plastic
material in eyeglasses could deform and
crack from high temperature.
▼Console Box
To use, open the lid.
▼Seat Side Box
CAUTION
When using the rear console cup holders,
remove any cups before opening the seat
side box.
If the seat side box is opened with cups still
in them, the lid will hit the cups and cause
the contents to spill.

NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. The period in which the tire
was manufactured (both week and year) is
indicated by a 4-digit number.
Refer to Tire Labeling on page 8-25.
▼Replacing a Wheel
WARNING
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
