2018 MAZDA MODEL 3 HATCHBACK coolant

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 6-25.
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 6-23).
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
6-27).
NOTE
(Without electric parking brake (EPB))
Do not use the parking brake in freezing
weather as it may freeze. Instead, shift
to P with an automatic transaxle and to
1 or R with a manual transaxle. Block
the rear wheels.
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.

Except Mexico (18–inch wheel vehicle)
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.
Mexico (18–inch wheel vehicle)
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.

▼Wrench Indicator Light
When the ignition is switched ON, the
wrench indicator light is illuminated and
then turns off after a few seconds.

The wrench indicator light is illuminated
when the preset maintenance period
arrives. Verify the content and perform
maintenance.
Refer to Maintenance Monitor on page 6-
16.
▼Low Engine Coolant Temperature
Indicator Light (Blue)
The light illuminates continuously when
the engine coolant temperature is low and
turns off after th
e engine is warm.
If the low engine coolant temperature
indicator light remains illuminated after
the engine has been sufficiently warmed
up, the temperature sensor could have a
malfunction. Consult an Authorized
Mazda Dealer.

CAUTION
If the air conditioner is used while driving
up long hills or in heavy traffic, monitor the
high engine coolant temperature warning
light to see if it is illuminated or flashing
(page 4-23).
The air conditioner may cause engine
overheating. If the warning light is
illuminated or flashing, 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,
set the mode selector dial at the
position 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. Set the mode sel
ector dial to the
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.
▼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.
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.

T: Tighten
Remarks:
*1 The engine oil and filter must b e changed at least once a year or within 12,000 km (7,500 miles) since last
engine oil and filter change. Re set the engine oil data whenever replacing the engine oil regardless of the
message/wrench indicator light display.
*2 Use of FL-22 is recommended when replacing engine coolant. Using engine coolant other than FL-22 may
cause serious damage to the engine and cooling system.
*3 According to state/provincial and federal regulations, failure to perform maintenance on these items will not
void your emissions warranties. H owever, Mazda recommends that all maintenance services be performed at
the recommended time or mileage/kilometer period to ensure long -term reliability.
*4 The Tire Pressure Monitoring System (TPMS) initialization must be performed so that the system operates
normally (if equipped).
*5 Check the tire repair fluid expiration date every year when pe rforming the periodic maintenance. Replace the
tire repair fluid bottle with ne w one before the expiration dat e.
