Add-On Non-Genuine Parts and Accessories
Non-genuine parts and accessories for Mazda vehicles can be found in stores.
These may ¿ t your vehicle, but they are not approved by Mazda for use with Mazda
vehicles. When you install non-genuine parts or accessories, they could affect your vehicle's
performance or safety systems; the Mazda warranty doesn't cover this. Before you install
any non-genuine parts or accessories, consult an Authorized Mazda Dealer.
WARNING
Always consult an Authorized Mazda Dealer before you install non-genuine parts or
accessories:
Improperly designed parts or accessories could seriously aff ect 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 inactivation, or a fi re 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
WARNING
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 other electrical devices
while the vehicle is moving and, instead, concentrate on the full-time job of driving.

Uniform Tire Quality Grading System (UTQGS)
Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National Highway
Traf ¿ c 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 speci ¿ ed government test course.
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 conditions of their use, however,
and may depart signi ¿ cantly from the norm because of variations in driving habits, service
practices and differences in road 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 controlled conditions on speci ¿ ed
government test surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.
WARNING
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 highest), B, and C, represent the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions on
a speci ¿ ed 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 passenger vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.

Uniform Tire Quality Grading System (UTQGS)
WARNING
Keep your vehicle's tires properly infl ated and not overloaded:
Driving with improperly infl ated or overloaded tires is dangerous. Excessive speed,
underinfl ation, or excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure. The temperature grade for this tire is established for a
tire that is properly infl ated and not overloaded.
These grades will be added to the sidewalls of passenger vehicle 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 sidewall between tread shoulder
and maximum section width.

Tire Information (U.S.A.)
Tire Labeling
Federal law requires tire manufacturers to place standardized information on the sidewall of
all tires. This information identi ¿ es and describes the fundamental characteristics of the tire
and also provides a tire identi ¿ cation number for safety standard certi ¿ cation and in case of
a recall.
Information on Passenger Vehicle Tires
Please refer to the sample below.
1. TIN: U.S. DOT tire identi ¿ cation number
2. Passenger car tire
3. Nominal width of tire in millimeters
4. Ratio of height to width (aspect ratio)

Tire Information (U.S.A.)
WARNING
Always check the tire infl ation pressures on a regular basis according to the
recommended tire infl ation pressure on the tire label and in conjunction with the
information in this owner's manual:
Driving your vehicle with under-infl ated tires is dangerous.
Under-infl ation is the most common cause of failures in any kind of tire and may result
in severe cracking, tread separation or “blowout”, with unexpected loss of vehicle
control and increased risk of injury. Under-infl ation increases sidewall fl exing and
rolling resistance, resulting in heat buildup and internal damage to the tire. It results in
unnecessary tire stress, irregular wear, loss of control and accidents. A tire can lose up to
half of its air pressure and not appear to be fl at!
It is impossible to determine whether or not tires are properly infl ated just by looking at
them.
Checking Tire Pressure
1. When you check the air pressure, make sure the tires are cold —meaning they are not hot
from driving even a mile.
2. Remove the cap from the valve on one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you over ¿ ll the tire, release air by pushing on the metal stem in the center of the valve.
Then recheck the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
N O T E
Some spare tires require higher in À ation pressure.
8. Visually inspect the tires to make sure there are no nails or other objects embedded that
could poke a hole in the tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or other
irregularities.

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.
If a tire wears evenly, a wear indicator will appear as a solid band across the tread.
Replace the tire when this happens.
New treadTread wear indicator
Worn tread
You should replace the tire before the band crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure monitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-129 .
N O T E
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. You should replace the
spare tire when you replace the other road tires due to the aging of the spare tire. 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 8-24 .
