▼To Resume Cruising Speed at More
Than 30 km/h (19 mph)
If the cruise control system is
temporarily canceled (such as by
applying the brake pedal) and the
system is still activated, the most
recent set speed will automatically
resume when the RES switch is
pressed.
If vehicle speed is below 30 km/h (19
mph), increase the vehicle speed up to
30 km/h (19 mph) or more and press
the RES switch.
▼To Te m p o ra r i l y C a n c e l
To temporarily cancel the system, use

When the cruise control system is
temporarily canceled by even one of
the applicable cancel conditions, the
speed cannot be re-set.
The cruise control cannot be
canceled while driving in manual
mode (selector lever shifted from D
to M position). Therefore, engine
braking will not be applied even if
the transmission is shifted down to a
lower gear. If deceleration is

Obstructions which are
lower than the sensor or thin may not be detected even though they were
detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or polesThings which absorb sonic waves easily such as cotton or snowAngular shaped objectsVery tall objects, and those which are wide at the topSmall, short objectsAlways have the system inspected at an Authorized Mazda Dealer if any shock is
applied to the bumpers, even in a minor accident. If the sensors are deviated, they
cannot detect obstructions.
The system may have a malfunction if a sound is not activated or the detection
indication is not displayed even when th e parking sensor OFF switch is pressed
and the parking sensor is operable. Have your vehicle inspected by an Authorized
Mazda Dealer.
The system may have a malfunction if th e indicator light does not turn on even

Operating Tips
▼Operating Tips
Operate the climate control system
with the engine running.
To prevent the battery from being
discharged, do not leave the fan
control switch on for a long period of
time with the ignition switched ON
when the engine is not running.
(With i-stop)
The airflow amount may decrease
slightly while the i-stop function is
operating.
Clear all obstructions such as leaves,
snow and ice from the hood and the
air inlet in the cowl grille to improve
the system
efficiency.
Use the climate control system to
defog the windows and dehumidify
the air.
The recirculate mode should be used
when driving through tunnels or
while in a traffic jam, or when you
would like to shut off outside air for
quick cooling of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows to let warm air
escape, then run the climate control
system.
Run the air conditioner about 10
minutes at least once a month to
keep internal parts lubricated.
Have the air conditioner checked
before the weather gets hot. Lack of
refrigerant may make the air
conditioner less efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If
the wrong type of refrigerant is used,
it could result in a serious
malfunction of the air conditioner.
Consult a professional, government certified repairer for the inspection
or repair because a special device is
required for the air conditioner
maintenance.
For details, consult an Authorized
Mazda Dealer.

▼Operation of Automatic Air
Conditioner
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 to select a desired temperature.
If you want to set the temperature
on the front passenger's side
separately from the driver's side,
turn the front passenger
temperature control dial to switch
the mode automatically to the
individual operation mode and set
the temperature for the front
passenger's side.
To turn off the system, press the power
switch.
NOTE
Set the control dial to the
recommended temperature of 22 °C
(72 °F), and then adjust it as desired.
Setting the temperature to maximum
hot or cold will not provide the
desired temperature at a faster rate.
When selecting heat, the system will
restrict airflow until the engine has
warmed to prevent cold air from
blowing out of the vents.
▼ Windshield 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 on 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 wi ll be hampered,
which could lead to a serious accident.
NOTE
Fogging on the windows clears up
more easily while the air conditioner
is on, but they will fog up more easily
if the air conditioner is turned off.
Be careful that the windows do not
fog up when doing any of the
following:
Switching to recirculate modeTu r n i n g off the air conditionerUse the temperature control dial to
increase the air
flow temperature
and defog the windshield more
quickly.
▼ Sunlight/Temperature Sensor
The climate control system measures
inside and outside temperatures,
humidity and sunlight using the
sunlight/temperature sensor. It sets
temperatures inside the cabin
accordingly.
CAUTION
Do not obstruct both sensors,
otherwise the climate control system
will not operate properly.
