4. Pull out the dipstick, wipe it clean,and reinsert it fully.

1. MAX
2. OK
3. MIN

5. Pull it out again and examine the level.
The level is normal if it is between
the MIN and MAX marks.
If it is near or below MIN, add
enough oil to bring the level to
MAX.
CAUTION
Do not overfill the engine oil. This
may cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly
before reinserting the dipstick.
7. Reinsert the dipstick fully.
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 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.
SKYACTIV-G 2.0 and SKYACTIV-G
2.5

SKYACTIV-G 2.5T

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 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 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
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.
