2019 MAZDA MODEL CX-30 Owners Manual (in English)

NOTE
If the replacement is not done using
the correct procedure indicated in the
service manual, it could cause an
engine malfunction. Consult an expert
repairer (we recommend an
Authorised Mazda Repairer) for
details.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a yearŠat the beginning of
the winter seasonŠand before
travelling 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
protection and to bring the level to
FULL.
Securely tighten the coolant reservoir
tank cap after adding coolant.
CAUTION
¾Radiator coolant will damage paint.
Rinse it off quickly if spilled.
¾If 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 expert repairer (we recommend an
Authorised Mazda Repairer).

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 expert repairer (we
recommend an Authorised Mazda
Repairer).

Window and Headlight
Washer Fluid
▼Inspecting Washer Fluid Level
WARNING
Use only windscreen washer fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windscreen, it will dirty the
windscreen, affect your visibility, and
could result in an accident.
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 bonnet 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 bonnet's secondary
latch keeps the bonnet from opening
when the primary latch is released.

Wiper Blades
▼Wiper Blades
CAUTION
¾Hot waxes applied by automatic car
washers have been known to
affect
the wiper's ability to clean windows.
¾To prevent damage to the wiper
blades, do not use petrol,
paraffin,
paint thinner, or other solvents on or
near them.
¾When the wiper lever is in the AUTO
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
¾If the windscreen above the rain
sensor is touched.
¾If the windscreen above the rain
sensor is wiped with a cloth.
¾If the windscreen is struck with a
hand or other object.
¾If 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.
¾Before lifting the windscreen wiper
blades
off the windscreen, always
follow the procedure for moving the
windscreen wiper blades. Otherwise,
a wiper blade, wiper arm, or the
bonnet could be damaged.
Refer to the Replacing Windscreen
Wiper Blades (page 6-32) section
for the procedure on how to move
the windscreen wiper blades to the
service position.
Contamination of either the
windscreen or the blades with foreign
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 Windscreen Wiper
Blades
When the wipers no longer clean well,
the blades are probably worn or
cracked.
Replace them.
CAUTION

wiper blade, wiper arm, or the
bonnet, perform the following
procedure.
¾Before lifting the windscreen wiper
blades off the windscreen, always
move them to the service position.
¾When putting the windscreen
wiper blades back on the
windscreen, make sure that they
are in the service position before
switching the ignition ON and
operating the windscreen wipers.
¾Replace 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
efficiency as the
genuine product.
¾To prevent damage to the wiper
arms and other components, do not
try to sweep the wiper arm by hand.
