▼Inspecting Engine Oil Level
NOTE
If the engine oil level warning
indication/warning light turns on,
add 1 L (0.26 US gal, 0.22 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 return to the
oil pan.
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.

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 F and L
marks on the coolant reservoir when
the engine is cool.

If it is at or near L, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and
to bring the level to F.
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 Fluid
▼ Inspecting Brake Fluid Level
WARNING
If the brake fluid level is low, have the
brakes inspected:
A low brake
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.
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 linings. If
it is excessively low, have the brake
system inspected by an Authorized
Mazda Dealer.

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
non-freezing 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
affect
the wiper's ability to clean windows.
 An operation malfunction may occur
or the wiper
effectiveness may be
reduced if a water-repellent coating
is used.
 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 procedure for moving the
windshield wiper blades. Otherwise,
a wiper blade, wiper arm, or the
hood could be damaged.

evaporates, the minerals will
concentrate and harden to form white
rings. The rings can damage your
vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according
to the instructions in this section.
These steps should be taken
immediately after you find water marks
on your vehicle's finish.
Pa i n t C h i p p i n g
Occurrence
Paint chipping occurs when gravel
thrown in the air by another vehicle's
tires hits your vehicle.
How to avoid paint chipping
Keeping a safe distance between you
and the vehicle ahead reduces the
chances of having your paint chipped
by flying gravel.
NOTE
The paint chipping zone varies with
the speed of the vehicle. For
example, when traveling at 90 km/h
(56 mph), the paint chipping zone is
50 m (164 ft).
In low temperatures a vehicle's
finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust
forming on your Mazda. Before this
happens, repair the damage by using
Mazda touch-up paint according to
the instructions in this section.
Failure to repair the affected area
could lead to serious rusting and
expensive repairs.

Follow all label and container
directions when using a chemical
cleaner or polish. Read all warnings
and cautions.
▼ Maintaining the Finish
Washing

▼Aluminum Wheel Maintenance
A protective coating is provided over
the aluminum wheels. Special care is
needed to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels.
NOTE
Do not use a wire brush or any
abrasive cleaner, polishing
compound, or solvent on aluminum
wheels. They may damage the
coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold water. Also, be
sure to clean the wheels after driving
on dusty or salted roads to help
prevent corrosion.
Avoid washing your vehicle in an
automatic car wash that uses
high-speed or hard brushes.
(20-inch wheel vehicle)
If your aluminum wheels lose luster,
apply wax which contains no
polishing powder.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of
the lights, do not use gasoline,
kerosene, rectified spirit, paint,
thinner, highly acidic detergents, or
strongly alkaline detergents.
Otherwise, these chemical agents
can discolor or damage the surfaces
resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or
battery fluid, it could cause
discoloration, staining, or paint
peeling. Wipe off any such chemical
agents or fluids using a soft cloth
immediately.
High water temperature and high
water pressure car washers are
available depending on the type of
high pressure car washer device. If
the car washer nozzle is put too
close to the vehicle or aimed at one
area for an extended period of time,
it could deform plastic parts or
damage the paint.
Do not use wax containing
compounds (polish). Otherwise, it
could result in paint damage.
In addition, do not use an electrical
or air tool to apply wax. Otherwise,
the frictional heat generated could
result in deformation of plastic parts
or paint damage.
