MAZDA MODEL 3 SEDAN 2019 Owners Manual

Engine Coolant
▼Inspecting Coolant Level
WA R N I N G
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has
been running, parts of the engine
compartment can become very hot. You
could be burned. Carefully inspect the
engine coolant in the coolant reservoir, but
do not open it.
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.
NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season―and before traveling where
temperatures may drop below freezing.

Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.

The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.

If it is at or near LOW, add enough coolant
to the coolant reservoir to provide freezing
and corrosion protec tion and to bring the
level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.

CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 If the “FL22” mark is shown on or near
the cooling system cap, 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.

If the coolant reser voir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
Brake/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid Level
WA R N I N G
If the brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
fluid level is dangerous.
A low level could indicate brake lining wear
or a brake system leak which could cause
the brakes to fail and lead to an accident.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is exce ssively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.

Washer Fluid
▼Inspecting Washer Fluid Level
WA R N I N G
Use only windshield washer fluid or plain
water in the reservoir:
Using radiator antifreeze as washer
fluid is
dangerous. If sprayed on the windshield, it
will dirty the windshield, affect your
visibility, and could result in an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather:
Operating your vehicle in temperatures
below 4 °C (40 °F) using washer fluid
without anti-freeze protection is dangerous
as it could cause impaired windshield
vision and result in an accident. In cold
weather, always use washer fluid with
anti-freeze protection.
NOTE
State or local regulations may restrict the
use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides adequate
freeze resistance for all regions and
climates in which the vehicle will be
operated.
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
The top of the float should be between F
and E.

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.

Body Lubrication
▼Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should be
lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.

Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
Wiper Blades
▼ Wiper Blades
CAUTION

Hot waxes applied by automatic car
washers have been known to affect the
wiper's ability to clean windows.
 To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched.
 If the windshield above the rain sensor
is wiped with a cloth.
 If the windshield is struck with a hand
or other object.
 If the rain sensor is struck with a hand
or other object from inside the vehicle.
Be careful not to pinch hands or fingers
as it may cause injury, or damage the
wipers. When washing or servicing the
vehicle, make sure the wiper lever is in
the
position.
Contamination of either the windshield or
the blades with forei gn matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.

If the blades are not wiping properly, clean
the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.
▼Replacing Windshield Wiper Blades
When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.

same
efficiency as the genuine product.
 To prevent damage to the wiper arms
and other components, do not try to
sweep the wiper arm by hand.
 Do not bend the blade rubber
unnecessarily when replacing it.

blade may deform and the windshield
wiper operation may be adversely
affected.
 Do not hold a wiper blade by its end
when raising the wiper arm. Otherwise,
the part may deform and the wiping
performance may lower.
NOTE
You can replace the wiper blades
yourself, however you cannot replace
the wiper arms.
If you want to replace the wiper arms,
consult an Authorized Mazda Dealer.

Battery
▼ Battery
WA R N I N G
Wash hands after handling the battery and
related accessories:
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the State
of California to cause cancer and
reproductive harm.
Read the following precautions
carefully before using the battery or
inspecting to ensure safe and correct
handling:
Always wear eye protection when
working near the battery:
Working without eye protection is
dangerous. Battery fluid contains
SULFURIC ACID which could cause
blindness if splashed into your eyes. Also,
hydrogen gas produced during normal
battery operation, could ignite and cause
the battery to explode.

Mazda3_8HE9-EA-18K_Edition3 2018-11-21 14:31:58

Wear eye protection and protective
gloves to prevent contact with battery
fluid:
Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID
which could cause serious injuries if it gets
in eyes, or on the skin or clothing. If this
happens, immediately flush your eyes with
water for 15 minutes or wash your skin
thoroughly and get medical attention.
Always keep batteries out of the
reach of children:
Allowing children to play near batteries is
dangerous. Battery fluid could cause
serious injuries if it gets in the eyes or on the
skin.
Keep flames and sparks away from
open battery cells and do not allow metal
tools to contact the positive (+) or negative
(-) terminal of the battery when working
near a battery. Do not allow the positive (+)
terminal to contact the vehicle body:
Flames and sparks near open battery cells
are dangerous. Hydrogen gas, produced
during normal battery operation, could
ignite and cause the battery to explode. An
exploding battery can cause serious burns
and injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.
Keep all flames and sparks away
from open battery cells because hydrogen
gas is produced from open battery cells
while charging the battery or adding
battery fluid:
Flames and sparks near open battery cells
are dangerous. Hydr ogen gas, produced
during normal battery operation, could
ignite and cause the battery to explode. An
exploding battery can cause serious burns
and injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.
NOTE
Before performing battery maintenance,
remove the battery cover.
