WA R N I N G
Do not perform maintenance work if you lack sufficient knowledge and experience or the
proper tools and equipment to do the work. Have maintenance work done by a qualified
technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can be
seriously injured while performing some maintenance procedures.
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.

vehicle. Mazda Genuine 0W-20 Oil is
required to achie
ve optimum fuel
economy.

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

(ILSAC)
Only use SAE 0W-20 oil “Certified For
Gasoline Engines” by the American
Petroleum Institute (API).

Except U.S.A., Canada, and Puerto Rico
Use SAE 5W-30 engine oil.
Oil container labels provide important
information.
A chief contribution this 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.

▼ Inspecting Engine Oil Level
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.

MIN
MAX
OK
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.
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.

Coolant reservoir
Cooling fan
Cooling system cap
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.

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
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 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.
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 w iping properly, clean
the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.
