Engine Coolant
▼Inspecting Coolant Level
WARNING
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 o ff 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 inde finitely 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.

SKYACTIV-G 2.5T

FULL
LOW
If it is at or near LOW, add enough
coolant to the coolant reservoir to
provide freezing and corrosion
protection 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 o ff 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 reservoir is empty or new
coolant is required frequently, consult
an Authorized Mazda Dealer.
Brake/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid
Level
WARNING
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 excessively low,
have the brake/clutch system
inspected by an Authorized Mazda
Dealer.

Washer Fluid
▼Inspecting Washer Fluid Level
WARNING
Use only windshield washer
fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fl uid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
a ff ect 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
aff ect
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 AUTO
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 OFF
position.

Before lifting the windshield wiper
blades off the windshield, always
follow the procedur e for moving the
windshield wiper blades. Otherwise,
a wiper blade, wiper arm, or the
hood could be damaged.
Refer to the Replacing Windshield
Wiper Blades (page 6-24) section
for the procedure on how to move
the windshield wipe r blades to the
service position.
Contamination of either the
windshield or the blades with foreign
matter can reduce wiper e ffectiveness.
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.
CAUTION

To prevent damaging a windshield
wiper blade, wiper arm, or the hood,
perform the following procedure.
 Before lifting the windshield wiper
blades o ff the windshield, always
move them to the service position.
 When putting the windshield
wiper blades back on the
windshield, make sure that they
are in the service position before
switching the ignition ON and
operating the windshield wipers.
 Replace with Mazda genuine wiper
blades. If they are replaced with
wiper blades other than a Mazda
genuine product, they may not wipe
with the same
effi ciency 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.
Otherwise, the metal stiff ener in the
blade may deform and the
windshield wiper operation may be
adversely a ffected.
 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.
