2018 MAZDA MODEL MX-5 MIATA spare tire

Dynamic Stability Control(DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4-64) and TCS (page
4-65).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to Warning Indication/Warning
Lights on page 4-26.
WA R N I N G
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
CAUTION
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
specified for
your Mazda on all four wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 Do not mix worn tires.
 The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too low in o ne 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 Warning Indication/Warning Lights on page 4-26.
Refer to Tire Inflation Pressu re Warning Beep on page 7-52.

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 illuminate more frequently. Vi sually 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 inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)

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 frequently needs inflating,
have it inspected.
▼Tire Rotation
WA R N I N G
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 12,000 km (7,500
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.
Refer to Scheduled Maintenance on page
6-4.

During rotation, inspect them for correct
balance.

Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking

After rotation, inflate all tire pressures to
specification (page 9-8) 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 reduced if
rotated from side to side.
(With limited-slip differential)
Do not use the following:
 Tires not of the designated size
 Tires of
different sizes or types at the
same time
 Tires not sufficiently inflated
If these instructions are not 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.

▼Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lu
g nuts, one on each
wheel will lock the tires and you must use
a special key to unlock them. This key will
attach to the lug wrench. Register them
with the lock manufacturer by filling out
the card provided in the glove
compartment and mailing it in the
accompanying envelope. If you lose this
key, consult an Authorized Mazda Dealer
or use the lock manufacturer's order form,
which is with the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire is
installed, one of the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.
Special key
Antitheft lug nut
To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the
antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
3. Place the lug wrench on top of the key and apply pressure. Turn the wrench
counterclockwise.
To install the antitheft lug nut
1. Place the special key on top of the nut,
and be sure to hold the key square to it.

Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.
6. Remove the tire blocks and store the tools and jack.
7. Check the inflation pressure. Refer to Tires on page 9-8.
WA R N I N G
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.
