2019 MAZDA MODEL 3 HATCHBACK coolant

Winter Driving
▼Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag of
sand or salt.
Ask an Authorized Mazda Dealer to check
the following:
Have the proper ratio of antifreeze in the
radiator.
Refer to Engine Coolant on page 6-17.
Inspect the battery and its cables. Cold
reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-15).
Inspect the ignition system for damage
and loose connections.
Use washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid (page
6-19).
NOTE
Remove snow before driving. Snow left
on the windshield is dangerous as it
could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
Never use warm or hot water for
removing snow or ice from windows and
mirrors as it could result in the glass
cracking.
Drive slowly. Braking performance can
be adversely affected if snow or ice
adheres to the brake
components. If this
situation occurs, drive the vehicle
slowly, releasing the accelerator pedal
and lightly applying the brakes several
times until the brake performance
returns to normal.
▼ Snow Tires
Use snow tires on all four wheels
Do not go faster than 120 km/h (75 mph)
while driving with sno
w tires. Inflate snow
tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more
than recommended on the tire pressure
label (driver's door frame), but never more
than the maximum c old-tire pressure
shown on the tires.

Mexico
The vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
Except Mexico
The vehicle is originally equipped with all
season radials designed to be used all year
around. In some extreme climates you
may find it necessary t o replace them with
snow tires during the winter months to
further improve traction on snow and ice
covered roads.

Cylinder Deactivation*
▼Cylinder Deactivation
The cylinder deactivation is a function
designed to reduce fuel consumption and
improve fuel economy by deactivating 2
out of the 4 cylinders while driving. The
function constantly determines which is
better for driving; 4 cylinders or 2
cylinders, regardless of the driver's
operations, and it performs the switching
automatically.
When the cylinder de
activation function
does not operate
The cylinder deactivation function does
not operate under the following
conditions.
The selector lever is in the P, N, or R
position (automatic transmission), or 1st
gear (manual transmission).
The engine oil temperature or engine
coolant temperature is low.
After disconnecting the battery
terminals for some reason, such as for
battery replacement.

▼Engine Coolant Temperature Gauge
Displays the engine coolant temperature.
The blue gauge indicates that the engine
coolant temperature is low, and the red
gauge indicates that the engine coolant
temperature is high and overheating.

CAUTION
When the engine coolant temperature
gauge needle is in the red range, the engine
coolant temperature is extremely high.
Drive slowly to reduce engine load. If the
engine coolant temperature gauge needle
is in the red range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take appropriate
measures.
Refer to Overheating on page 7-20.
NOTE
If the engine or engine coolant
temperature is high or low, the engine
output may be restricted to protect the
engine.
During normal driving, the engine
coolant temperature stabilizes at 100 °C
(210 °F) or less, and the gauge indicates
a range lower than 100 °C (210 °F).
▼Fuel Gauge
The fuel gauge shows approximately how
much fuel is remaining in the tank when
the ignition is switched ON. We
recommend keeping the tank over 1/4 full.

1. Full
2. 1/4 Full
3. Empty

If the low fuel warni
ng light illuminates or
the fuel level is very low, refuel as soon as
possible.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-33.
NOTE
After refueling, it may require some time
for the indicator to stabilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.

▼Outside Temperature Display
When the ignition is switched ON, the
outside temperatur
e is displayed.

NOTE
Under the following conditions, the
outside temperature display may differ
from the actual outside temperature
depending on the surroundings and
vehicle conditions:
Significantly cold or hot temperatures.
Sudden changes in outside
temperature.
The vehicle is parked.
The vehicle is driven at low speeds.
Changing the Temperature Unit of the
Outside Temperature Display
The outside temperature unit can be
switched between Celsius and Fahrenheit.
Settings can be changed by operating the
center display screen.
Refer to the Settings section in the Mazda
Connect Owner's Manual.
NOTE
When the temperature unit indicated in the
outside temperature display is changed,
the temperature unit indicated in the
engine coolant gauge display changes in
conjunction with it.
▼ Distance-to-empty
This displays the approximate distance
you can travel on the remaining fuel based
on the fuel economy.
The distance-to-empty will be calculated
and displayed every second.

NOTE
Even though the distance-to-empty
display may indicate a sufficient amount
of remaining driving distance before
refueling is required
, refuel as soon as
possible if the fuel level is very low or
the low fuel warning light illuminates.
The display will not change unless you
add more than approximately 9 L (2.3
US gal, 1.9 Imp gal) of fuel.
The distance-to-empty is the
approximate remaining distance the
vehicle can be driven until all the
graduation marks in the fuel gauge
indicating the remaining fuel supply
disappear.
If there is no past fuel economy
information such as after first
purchasing your vehicle or the
information is deleted when the battery
cables are disconnected, the actual
distance-to empty/range may differ from
the amount indicated.

▼Cooling (Type A)
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
7-28).
The air conditioner may cause engine
overheating. If the warning indication is
displayed, turn the air conditioner off (page
7-20).
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
on the air conditioner.
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
(Type A)
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.
