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.
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.

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
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
▼ 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.
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.
Refer to the Replacing Windshield
Wiper Blades (page 6-21) section
for the procedure on how to move
the windshield wipe r blades to the
service position.

4. Inspect the fuse and replace it if it isblown.
1. Normal
2. Blown
5. Insert a new fuse of the same amperage rating , and make sure it
fits tightly. If it does not
fit tightly,
have an expert install it. Consult an
Authorized Mazda Dealer.
If you have no spare fuses, borrow
one of the same rating from a
circuit not essential to vehicle
operation, such as the audio or
accessory socket circuit.
CAUTION
Always replace a fuse with a
genuine Mazda fuse or equivalent
of the same rating. Otherwise you
may damage the electric system.
6. Reinstall the cover and make sure that it is securely installed.
Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses
in the cabin are normal, inspect the
fuse block under the hood.
If a fuse is blown, it must be replaced.
Follow these steps:
1. Make sure the ignition is switched off, and other switches are off.
2. Remove the fuse block cover.
3. If any fuse but the MAIN fuse is blown, replace it with a new one of
the same amperage rating .
1. Normal
2. Blown

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
CAUTION
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.
Refer to the Replacing Windshield
Wiper Blades (page 6-21) section for
the procedure on how to move the
windshield wiper blades to the
service position.
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 or wiped with a
cloth.
If the windshield is struck with a
hand or other object from either
outside or inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wiper lever is in
the AUTO position and the ignition is
switched ON as fingers could be
pinched or the wipers and wiper
blades damaged when the wipers
activate automatically.
If you are going to clean the
windshield, be sure the wipers are
turned off completely (when it is
most likely that the engine is left
running) this is particularly important
when clearing ice and snow.
