2020 MAZDA MODEL 3 HATCHBACK warning

▼When a tire pressure decreases
If the TPMS warning light turns on, a tire
pressure may be low. Inspect the tire
pressures and adjust them to the correct
inflation pressure.
Refer to Tire Pressure Monitoring System
(TPMS) Warning Ind
ication/Warning
Light (Turns on) on page 7-36.
▼ Tires and Wheels
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force to
the air valve of the tire pressure sensor.
Otherwise, the tire pressure sensor could be
damaged.
When changing tires and wheels
When changing the tires or wheels (such
as installing winter tires), it will be
necessary to register the ID signal code of
the tire pressure s
ensor to the TPMS.
Have an Authorized Mazda Dealer do the
registration or register the ID signal codes
of the tire pressure sensors using the
following procedure.
NOTE
The tire pressure sensors on each wheel
have a unique ID signal code. For the
TPMS to operate correctly, the ID signal
codes of the tire pressure sensors need to
be registered to the system.
1. Wait more than 19 minutes after
changing a tire or wheel.
2. After more than 19 minutes havepassed, drive the vehicle at a speed of
about 25 km/h (16 mph) or faster for 3
minutes or longer. While driving, the
ID signal codes of the tire pressure
sensors are automatically registered.
NOTE
If you drive the vehicle within 19 minutes
of changing a tire or wheel, the TPMS
warning light will flash because the ID
signal codes for the tire pressure sensors
were not registered. In this case, stop the
vehicle and register the ID signal codes of
the tire pressure sensors following the
procedure.
When replacing tires and wheels
CAUTION
When replacing the tires and wheels,
consult an Authorized Mazda Dealer
Otherwise, the tire pressure sensors could
be damaged when replacing them.
 Do not install non-genuine wheels. If
wheels other than genuine ones are
installed, it may not be possible to install
the tire pressure sensors.
When replacing a tire or wheel, always
install the tire pressure sensor. The
following combinations of tires, wheels, or
tires and wheels are possible.
The tire pressure s ensor from the old
wheel is removed and it is installed to
the new wheel.
Only a tire is replaced without replacing
the tire pressure sensor and wheel.
A new tire pressure se nsor is installed to
a new wheel.

▼Cooling (With A/C switch)
1. Press the switch.
2. Set the temperature control dial to the
cold position.
3. Set the fan control dial to the desired
speed.
4. Turn on the air conditioner by pressing
the A/C switch.
5. After cooling begins, adjust the fan control dial and temperature control
dial as needed to maintain maximum
comfort.
CAUTION
If the air conditioner is used while driving
up long hills or in heavy traffic, monitor the
high engine coolant temperature warning
indication to see if it is displayed (page
7-29).
The air conditioner may cause engine
overheating. If the warning indication is
displayed, turn the air conditioner off (page
7-21).
NOTE
When maximum cooling is desired, set
the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then turn the fan control dial
fully clockwise.
If warmer air is desired at floor level,
press the
switch and adjust the
temperature control dial to maintain
maximum comfort.
The air to the floor is warmer than air
to the face (except wh en the temperature
control dial is set at the extreme hot or
cold position).
▼ Ventilation
1. Press the switch.
2. Set the air intake selector 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. Press the switch.
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

WA R N I N G
Do not defog the windshield using the
switch with the temperature control set to
the cold position:
Using the
switch 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
switch.
NOTE
(With A/C switch)
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.
