climate control MAZDA MODEL MX-5 MIATA 2018 User Guide

The air to the floor is warmer than air
to the face (except when the temperature
control dial is set at the extreme hot or
cold position).
▼Ventilation
1. Set the mode selector dial to the
position.
2. Set the air intake s elector to the outside
air position (indicator light turns off).
3. Set the temperature control dial to the desired position.
4. Set the fan control dial to the desired
speed.
▼Windshield Defrosting and
Defogging
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the desired position.
3. Set the fan control dial to the desired
speed.
4. If dehumidified heating is desired, turn
on the air conditioner.
WA R N I N G
Do not defog the windshield using the
position with the temperature 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.
(Type A)
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 wind shield. In the
or
position, the outside air position cannot
be changed to the recirculated air
position.
(Type B)
When the fan control dial is ON, and the
mode selector dial is in the
position,
the outside air position is automatically
selected to defrost the windshield. In the
position, the outside air position
cannot be changed to the recirculated
air position.
▼ Dehumidifying
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 (indicator light turns off).
3. Set the temperature control dial to the

NOTE
One of the functions of the air conditioner
is dehumidifying the air and, to use this
function, the temperature does not have to
be set to cold. Therefore, set the
temperature control dial to the desired
position (hot or cold) and turn on the air
conditioner when you want to dehumidify
the cabin air.

Commands useable anytime during
voice recognition
“Help” or “Go Back” are commands
which can be used at anytime during voice
recognition.
Help function use
The help function informs the user of all
the available voice commands under the
current conditions.
1.Say: [Beep] “Help”
2. Follow the promp ts to receive the
appropriate voice guidance
instructions.
Returning to previous operation
This command is for returning to the
previous operation while in the voice
recognition mode.
Say: [Beep] “Go Back”
To prevent a deterioration in the voice
recognition rate and voice quality, the
following points should be observed:
The voice recognition cannot be
performed while voice guidance or the
beep sound is oper ating. Wait until
the voice guidance or the beep sound
is finished before saying your
commands.
Dialects or differen t wording other than
hands-free prompts cannot be
recognized by voice recognition. Speak
in the wording specified by the voice
commands.
It is not necessary to face the
microphone or approach it. Speak the
voice commands while maintaining a
safe driving position.
Do not speak too slow or too loud.
Speak clearly, without pausing between
words or numbers.
Close the windows and/or the
convertible top to reduce loud noises
from outside the vehicle, or turn down
the airflow of the climate control system
while Bluetooth
® Hands-Free is being
used.
Make sure the vents are not directing air
up towards the microphone.
NOTE
If the voice recognition performance is not
satisfactory.

▼Replacing a Tire
WA R N I N G
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 ti
re 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.
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 8-25.

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.
