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
State or local regulations may restrict
the use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides
adequate freeze resistance for all
regions and climates in which the
vehicle will be operated.
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
1. F
2. E
The top of the
float should be between
F and E.

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold
weather to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.
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.

NOTE
A spot remover to remove oil, tar, and
similar materials will usually also take
off the wax. Rewax these areas even if
the rest of the vehicle does not need it.
▼Repairing Damage to the Finish
Deep scratches or chips on the finish
should be repaired promptly. Exposed
metal quickly rusts and can lead to
major repairs.
CAUTION
If your Mazda is damaged and needs
metal parts repaired or replaced, make
sure the body shop applies
anti-corrosion materials to all parts,
both repaired and new. This will
prevent them from rusting.
▼Bright-Metal Maintenance
Use tar remover to remove road tar
and insects. Never do this with a
knife or similar tool.
To prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high
luster.
During cold weather or in coastal
areas, cover bright-metal parts with a
coating of wax or preservative
heavier than usual.
It would also help
to coat them with noncorrosive
petroleum jelly or some other
protective compound.
CAUTION
Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or anodized
aluminum parts. This may result in
damage to the protective coating and
cause discoloration or paint
deterioration.
▼ Underbody Maintenance
Road chemicals and salt used for ice
and snow removal and solvents used
for dust control may collect on the
underbody. If not removed, they will
speed up rusting and deterioration of
such underbody parts as fuel lines,
frame,
floor pan, and exhaust system,
even though these parts may be coated
with anti-corrosive material.

Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try
also to do this every month.

Pay special attention to these areas
because they easily hide mud and dirt.
It will do more harm than good to wet
down the road grime without
removing it.

The lower edges of doors, rocker
panels, and frame members have drain
holes that should not be clogged.
Water trapped there will cause rusting.

WARNING
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
affected.
▼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.
▼ 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.

WARNING
Do not apply oil or grease to lug
nuts and bolts and do not tighten
the lug nuts beyond the
recommended tightening torque:
Applying oil or grease to lug nuts
and bolts is dangerous. The lug nuts
could loosen while driving and
cause the tire to come off, resulting
in an accident. In addition, lug nuts
and bolts could be damaged if
tightened more than necessary.
4. Turn the jack handle counterclockwise using the lug
wrench and lower the vehicle.
5. Use the lug wrench to tighten the nuts in the order shown.

If you are unsure of how tight the
