control set to the cold 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. Set
the temperature control to the hot or
warm position when using the
position.
NOTE
For maximum defrosting, turn on the air
conditioner, set the temperature control
dial to the extreme hot position, and
turn the fan control dial fully clockwise.
If warm air is desired at the floor, set the
mode selector dial to the position. When the fan control dial is ON, and the
mode selector dial is in the or
position, the air conditioner is
automatically turned on and the outside
air position is automatically selected to
defrost the windshield. In the
or
position, the outside air position cannot
be changed to the recirculated air
position.
Dehumidifying (With air
conditioner)
Operate the air conditioner in cool or cold
weather to help defog the windshield and
side windows.
1. Set the mode selector dial to the desired
position.
2. Set the air intake selector to the outside
air position.
3. Set the temperature control dial to the
desired position.
4. Set the fan control dial to the desired
speed.
5. Turn on the air conditioner by pressing
the A/C switch.
NOTE
One of the functions of the air conditioner
is dehumidifying the air and, to use

Temperature control dial
This dial controls temperature. Turn it
clockwise for hot and counterclockwise
for cold.
Fan control dial
The fan has seven speeds.
AUTO position
The amount of airflow will be
automatically controlled in accordance
with the set temperature.
Except AUTO position
The airflow amount can be adjusted to the
desired level by turning the dial.
0 position
To turn off the system, set the dial to 0
position.
Mode selector dial
Turn the mode selector dial to select
airflow mode (page 5-4).
AUTO position
The airflow mode automatically adjusts to
the selected temperature.
Except AUTO position
The desired airflow position can be
selected by turning the dial.
NOTE
With the airflow mode set to the
position and the temperature control
dial set at a medium temperature,
heated air is directed to the feet and air
at a comparably lower temperature will
flow through the central, left and right
vents.
When the fan control dial is ON, and the
mode selector dial is in the or
position, the air conditioner is
automatically turned on and the outside
air position is automatically selected to
defrost the windshield. In the
or
position, the outside air position cannot
be changed to the recirculated air
position.
A/C switch
The air-conditioning (cooling/
dehumidifying functions) can be turned on
or off by pressing the switch while the fan
control dial is at a position other than 0.
The indicator light turns on while the air-
conditioning is operating.
NOTE
The air conditioner may not function when
the outside temperature approaches 0 °C
(32 °F).
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)

Outside air position (indicator light
turned off)
Outside air is allowed to enter the
cabin. Use this mode for ventilation or
windshield defrosting.
WARNING
Do not use the position 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.
Operation of Automatic Air-
Conditioning
1. Set the mode selector dial to the AUTO
position.
2. Set the air intake selector to the outside
air position (indicator light turned off).
NOTE
If the recirculated air position is used
for long periods in cold weather or high
humidity, the windshield may fog up more
easily.
3. Set the fan control dial to the AUTO
position.
4. Press the A/C switch to operate the air-
conditioning (turn indicator light on).
5. Set the temperature control dial to the
desired position.
6. To turn off the system, set the fan
control dial to the 0 position.
NOTE
Setting the temperatur e to maximum
hot or cold will not provide the desired
temperature at a faster rate.
When selecting heat, the system will
restrict airflow until it has warmed to
prevent cold air from blowing out of the
vents.
Windshield Defrosting and
Defogging
Set the mode selector dial to the
position and turn the fan control dial to the
desired speed.
In this position, the outside air position
is automatically selected, and when the
fan control dial is ON, the air conditioner
automatically turns on. The air conditioner
will directly dehumidify the air to the
front windshield and side windows (page
5-4). 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.

Maintenance and Care
Owner Maintenance
*Some models.
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.
Replace all four tires at the same time: Replacing just one tire is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tires at the
same time.
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
New tread Tread 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 4-96.
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. 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.
Replacing 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
A wrong-sized wheel may adversely
affect:

Customer Information and Reporting Safety Defects
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
Traffic Safety Administration for grading tires by tread wear, traction, and temperature
performance.
Tread Wear
The tread wear grade is a comparative rating based on the wear rate of t\
he 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 o\
n 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.
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 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.
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 c\
ontrolled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degener\
ate 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 requ\
ired by law.
