2008 MAZDA MODEL MX-5 MIATA POWER RETRACTABLE HARDTOP sensor

Black plate (178,1)
Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-6).
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.NOTE
lPerform tire pressure adjustment when the
tires are cold. Tire pressure will vary
according to the tire temperature, therefore
let the vehicle stand for 1 hour or only drive
it 1.6 km (1 mile) or less before adjusting
the tire pressures. When pressure is
adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may
turn on after the tires cool and pressure
drops below specification.
Also, an illuminated TPMS warning light,
resulting from the tire air pressure dropping
due to cold ambient temperature, may go
out if the ambient temperature rises. In this
case, it will also be necessary to adjust the
tire air pressures. If the TPMS warning
light illuminates due to a drop in tire air
pressure, make sure to check and adjust the
tire air pressures.
lAfter adjusting the tire air pressures, it may
require some time for the TPMS warning
light to go out. If the TPMS warning light
remains illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it goes out.
lTires can loose a little air quite naturally
over time and the TPMS cannot tell if the
tires are getting too soft over time or you
have a flat. However, when you find one
low tire 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 tire for cuts and
any metal 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 refilling the trouble tire as
leaks are dangerous - take it to an
Authorized Mazda Dealer which has all the
equipment to fix tires, TPMS systems and
order the best replacement tire for your
vehicle.

a beep sound will be heard for
approximately 30 seconds.
Refer to Vehicle with run-flat tires on
page 7-3.
qSystem Error Activation
When the TPMS warning light flashes,
there may be a system malfunction.
Consult an Authorized Mazda Dealer.
A system error activation may occur in
the following cases:
lWhen there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
lWhen 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.
lWhen using the following devices in
the vehicle that may cause radio
interference with the receiver unit.
lA digital device such as a personal
computer.
lA current converter device such as a
DC-AC converter.
lWhen excess snow or ice adheres to
the vehicle, especially around the
wheels.
lWhen the tire pressure sensor batteries
are exhausted.
lWhen using a wheel with no tire
pressure sensor installed.
lWhen using tires with steel wire
reinforcement in the side walls.
lWhen using tire chains.
qTires 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
Tire pressure sensor ID signal code
registration is completed when an
Authorized Mazda Dealer changes your
vehicle's tires.
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, turn theignition switch to the ON position, then
turn it back to the ACC or LOCK
position.
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 for
about 15 minutes, after which the sensor ID
signal code will register upon driving the
vehicle for 10 minutes.
Replacing tires and wheels
CAUTION
Ø
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.
Ø 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.
lThe tire pressure sensor is removed
from the old wheel and installed to the
new one.
lThe same tire pressure sensor is used
with the same wheel. Only the tire is
replaced.
lA new tire pressure sensor is installed
to a new wheel.

Changing a Tire
WARNING
Be sure to follow the directions for
changing a tire, and never get under a
vehicle that is supported only by a jack:Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure
someone.
Never allow anyone inside a vehicle
supported by a jack: Allowing someone to remain in a
vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.
CAUTION
(With Tire Pressure Monitoring
System)
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.
NOTE
lMake sure the jack is well lubricated before
using it.
(With Tire Pressure Monitoring System)
lBe sure to register the tire pressure sensor
ID signal code whenever tires or wheels are
changed (page 5-31).
1. Park on a level surface off the right-of- way and firmly set the parking brake.
2. Put a vehicle with an automatic transmission in Park (P), a manual
transmission in Reverse (R) or 1, and
turn off the engine. 3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle
and away from the vehicle and traffic.
5. Remove the jack, and tool (page 7-5).
6. Block the wheel diagonally opposite the tire to be changed. When blocking
a wheel, place a tire block both in front
and behind the tire.
NOTE
When blocking a tire, use rocks or wood blocks
of sufficient size if possible to hold the tire in
place.

qTire Rotation
To equalize tread wear, rotate the tires if
irregular wear develops. According to the
scheduled maintenance charts.Refer to
Scheduled Maintenance on page 8-3.
During rotation, inspect them for correct
balance.
NOTE
Because your vehicle is not equipped with a
spare tire, you cannot do a tire rotation safely
with the jack that comes with your vehicle.
Have an Authorized Mazda Dealer perform
tire rotation.
Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
lIncorrect tire pressurelImproper wheel alignmentlOut-of-balance wheellSevere braking
After rotation, inflate all tire pressures to
specification (page 10-6) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to
rear, not from side to side. Tire
performance will be weakened if
rotated from side to side.
CAUTION
Limited-Slip Differential system;
don't use the following:
Ø Tires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
CAUTION
(With Tire Pressure Monitoring
System)
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.
