You can do the following scheduled
maintenance items if you have some
mechanical ability and a few basic tools
and if you closely follow the directions in
this manual.
Engine coolant (page 6-17)
Engine oil (page 6-16)

Improper or incomplete service may result
in problems. This section gives

If you must run the engine while working
under the hood, make certain that you
remove all jewelry (especially rings,
bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing
before getting near the engine or cooling
fan which may turn on unexpectedly:
Working under the hood with the engine
running is dangerous. It becomes even
more dangerous when you wear jewelry,
loose clothing or have long hair or a long
beard.
Either can become entangled in moving
parts and result in injury.
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 leave items in the engine
compartment:
After you have finished checking or doing
servicing in the engine compartment, do
not forget and leave items such as tools or
rags in the engine compartment.
Tools or other items left in the engine
compartment could cause engine damage
or a fire leading to an unexpected accident.
Hood
▼ Hood
WA R N I N G
Always check that the hood is closed and
securely locked:
A hood that is not closed and securely
locked is dangerous as it could fly open
while the vehicle is moving and block the
driver's vision which could result in a
serious accident.
▼Opening the Hood
1. With the vehicle
parked, pull the
release handle to unlock the hood.

2. Insert your hand into the hood opening, slide the latch lever to the
left, and lift up the hood.

Engine Oil
▼Engine Oil
NOTE
Changing the engine oil should be
performed by an Authorized Mazda
Dealer.
Refer to Introduction (page 6-2) for
owner's responsibility in protecting your
investment.
▼Recommended Oil
U.S.A., Canada
Use ILSAC GF-V or higher/ SAE
0W-20 engine oil.
Mazda Genuine Oil is used in your Mazda
vehicle. Mazda Genuine 0W-20 Oil is
required to achie
ve optimum fuel
economy.

For maintenance service, Mazda
recommends Mazda Genuine Parts and
Oil.

Only use SAE 0W-20 oil “Certified For
Gasoline Engines” by the American
Petroleum Institute (API).
Oil with this tradem ark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International
Lubricant Standardization and Approval
Committee (ILSAC), comprised of U.S.
and Japanese automobile manufacturers.

Except U.S.A., Canada
Use SAE 5W-30 engine oil.
Oil container labels provide important
information.
A chief contribution th is type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.

For maintenance service, Mazda
recommends Mazda Genuine Parts and
Castrol
® (Mexico only).


(Mexico)
Use API SM or higher, or ILSAC GF-IV
or higher/SAE 5W-30 engine oil. If SAE
5W-30 engine oil is not available, use SAE
5W-20 engine oil.

The quality designation SM, or ILSAC
must be on the label.

▼ Inspecting Engine Oil Level
NOTE
If the engine oil level warning
indication/warning light turns on, add 1
L (0.3 US gal, 0.2 Imp gal) of engine oil.
1. Be sure the vehicle is on a level surface.
2. Warm up the engine to normal
operating temperature.
3. Turn it off and wait at least 5 minutes
for the oil to retur n to the oil pan.
4. Pull out the dipstic k, 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
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.

Owner Maintenance
6-17
Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

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 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 reserv oir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
