2018 MAZDA MODEL MX-5 Owners Manual (in English)

Add-On Non-Genuine Parts and Accessories
Non-genuine parts and accessories for Mazda vehicles can be found in stores.
These may fit your vehicle, but they are not approved by Mazda for use with Mazda
vehicles. When you install non-genuine parts or accessories, th ey could affect your vehicle's
performance or safety systems; th e Mazda warranty doesn't cover this. Before you install
any non-genuine parts or accessories, consult an Authorized Maz da Dealer.
WA R N I N G
Always consult an Authorized Mazda Dealer before you install non-genuine parts or
accessories:
Improperly designed parts or accessories could seriously affect your vehicle's performance or
safety systems. This could cause you to have an accident or increase your chances of injuries
in an accident.
Be very careful in choosing and installing add-on electrical equipment, such as mobile
telephones, two-way radios, stereo systems, and car alarm systems:
Incorrectly choosing or installing improper add-on equipment or choosing an improper
installer is dangerous. Essential systems could be damaged, causing engine stalling, air-bag
(SRS) activation, ABS/TCS/DSC inacti vation, or a fire in the vehicle.
Mazda assumes no responsibility for death, injury, or expenses that may result from the
installation of add-on non-genuine parts or accessories.

Cell Phones Warning
WA R N I N G
Please comply with the legal regulations concerning the use of communication equipment in
vehicles in your country:
Use of any electrical devices such as cell phones, computers, portable radios, vehicle
navigation or other devices by the driver while the vehicle is moving is dangerous. Dialing a
number on a cell phone while driving also ties-up the driver's hands. Use of these devices will
cause the driver to be distracted and could lead to a serious accident. If a passenger is unable
to use the device, pull off the right-of-way to a safe area before use. If use of a cell phone is
necessary despite this warning, use a hands-free system to at least leave the hands free to
drive the vehicle. Never use a cell phone or othe r electrical devices while the vehicle is moving
and, instead, concentrate on the full-time job of driving.

Event Data Recorder (U.S.A. and Canada)
This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is
to record, in certain crash or ne ar crash-like situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in understanding how a vehicle’s systems
performed. The EDR is designed to record data related to vehicl e dynamics and safety
systems for a short period of time, typically 30 seconds or les s. The EDR in this vehicle is
designed to record such data as:
How various systems in you r vehicle were operating;
Whether or not the driver and passenger safety belts were buckl ed/fastened;
How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better understanding of the circu mstances in which crashes
and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if a non-trivial cra sh or near crash-like situation
occurs; no data are recorded by the EDR under normal driving co nditions and no personal
data (e.g., name, gender, age, an d crash location) are recorded. However, other parties, such
as law enforcement, could combine the EDR data with the type of personally identifying
data routinely acquired du ring a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle manufacturer, oth er parties, such as law
enforcement, that have the special equipment, can read the info rmation if they have access
to the vehicle or the EDR.

Mazda will not disclose any of the data recorded in an EDR to a third party unless:
A written agreement from the vehicle owner or the lessee is obtained
Officially requested by the police or other law enforcement authorities
Used as a defense for Mazda in a lawsuit, claim, or arbitration
Ordered by a judge or court
However, if necessary Mazda will:
Use the data for research on Mazda vehicle performance, includi ng safety.
Disclose the data or the summarized data to a third party for research purposes without
disclosing vehicle or owner identification information.

NOTE
The recorded data may vary depending on the vehicle grade and optional equipment. Voice
and images are not recorded.

Data handling
Mazda and its subcontracting parties may obtain and use the rec orded data for vehicle
malfunction diagnosis, research and development, and quality im provement.
Mazda will not disclose or provide any of the obtained data to a third party unless:
An agreement from the vehicle owner (agreements from lessor and lessee for leased
vehicle) is obtained
Officially requested by the police or other law enforcement aut horities
For statistical processing by a research institution after processing the data so that
identification of the owner o r the vehicle is impossible

Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National Highway
Traffic Safety Administration for grading tires by tread wear, traction, and temperature
performance.
▼ Tr e a d We a r
The tread wear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a specified government test cour
se.
For example, a tire graded 150 would wear one-and-a-half times as well on the government
course as a tire graded 100.

The relative performance of tires depends upon the actual condi tions of their use, however,
and may depart significantly from the norm because of variation s in driving habits, service
practices and differences in ro ad characteristics and climate.
▼Traction-AA, A, B, C
The traction grades, from highest
to lowest, are AA, A, B, and C. These grades represent the
tire's ability to stop on wet pavement as measured under contro lled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.
WA R N I N G
The traction grade assigned to this tire is based on braking (straight ahead) traction tests and
does not include acceleration cornering (turning), hydroplaning, or peak traction
characteristics.
▼ Temperature-A, B, C
The temperature grades A (the hi
ghest), B, and C, represent the tire's resistance to the
generation of heat and its ability to dissipate heat when teste d under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.

Grade C corresponds to a level of performance which all passeng er vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the labo ratory test wheel than the minimum required by law.

WA R N I N G
Keep your vehicle's tires properly inflated and not overloaded:
Driving with improperly inflated or overl oaded tires is dangerous. Excessive speed,
underinflation, or excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure. The temperatur e grade for this tire is established for a tire
that is properly inflated and not overloaded.

These grades will be added to the sidewalls of passenger vehicl e tires over the next several
years according to a schedule established by the NHTSA and the tire manufacturers.

The grade of tires available as standard or optional equipment on Mazda vehicles may vary
with respect to grade.

ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND TO
ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.
▼ UNIFORM TIRE QUALITY GRADING
Quality grades can be found where applicable on the tire sidewa
ll between tread shoulder
and maximum section width.
