Air intake selector
Outside or recirculated air positions can
be selected. Press the switch to select
outside/recirculated air positions.
Recirculated air position (indicator
light illuminated)
Use this position when going through
tunnels, driving in congested traffic (high
engine exhaust areas), high ambient
humidity conditions, or when quick
cooling is desired.
Outside air position (indicator light
turned off)
Use this position for normal conditions
and defogging.
WARNING
Do not use theposition in cold or
rainy weather: Using the
position in cold or
rainy weather is dangerous as it will
cause the windows to fog up. Your
vision will be hampered, which could
lead to a serious accident.
AMB (Ambient Temperature) switch

qOperation of Automatic Air
Conditioning
1. Press the AUTO switch. Selection of
the airflow mode, air intake selector
and amount of airflow will be
automatically controlled.
2. Use the temperature control dial toselect a desired temperature.
Cold Hot
To turn off the system, press the OFF
switch.
NOTE
lSetting the temperature to maximum high
or low will not provide the desired
temperature at a faster rate.
lWhen selecting heat, the system will restrict
airflow until it has warmed to prevent cold
air from blowing out of the vents.
qWindshield Defrosting and Defogging
Press the windshield defroster switch.
In this position, the outside air position is
automatically selected, and the air
conditioner automatically turns on. The
air conditioner will directly dehumidify
the air to the front windshield and side
windows (page 6-4). Airflow amount will
be increased.
WARNING
Set the temperature control to the hot
or warm position when defogging (
position):
Using the
position with the
temperature control set to the cold
position is dangerous as it will cause
the outside of the windshield to fog
up. Your vision will be hampered,
which could lead to a serious
accident.
NOTE
Use the temperature control dial to increase
the air flow temperature and defog the
windshield more quickly.

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. You should
replace the spare tire when you replace the
other road tires due to the aging of the spare
tire. Regarding the manufacturing week and
year is indicated with 4 digit.
Refer to The tire labeling on page 9-23.
qReplacing 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
ØA wrong-sized wheel may
adversely affect:
ØTire fit
ØWheel and bearing life
ØGround clearance
ØSnow-chain clearance
ØSpeedometer calibration
ØHeadlight aim
ØBumper height
ØTire Pressure Monitoring
System
ØLimited-Slip Differential System
Ø (With Tire Pressure Monitoring
System)
ØWhen 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.
ØThe 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
Be sure to install the tire pressure sensors
whenever tires or wheels are replaced. Refer to
Tires and Wheels on page 5-31.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
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.

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.
qTread Wear
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 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 significantly from the norm because of variations in driving habits, service
practices and differences in road characteristics and climate.
qTraction-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
specified 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.
qTemperature-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 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 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.
