Fuses

Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate circuit
protector. If a fuse has blown, the inside
element will be melted.

If the same fuse blows again, avoid using
that system and consult an Authorized
Mazda Dealer as soon as possible.

▼ Fuse Replacement

Replacing the fuses on the vehicle's left
side

If the electrical system does not work, first
inspect the fuses on the vehicle's left side.

1. Make sure the ignition is switched off,

and other switches are off.

2. Open the fuse panel cover.

3. Pull the fuse straight out with the fuse

puller provided on the fuse block
located in the engine compartment.

4. Inspect the fuse and replace it if it is

blown.

Normal

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. We recommend 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 OUTLET circuit.

CAUTION

Always replace a fuse with a genuine
Mazda fuse or equivalent of the same
rating. Otherwise you may damage the
electric system.

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.

Exterior Care

The paintwork on your Mazda represents
the latest technical developments in
composition and methods of application.

Environmental hazards, however, can
harm the paint's protective properties, if
proper care is not taken.

Here are some examples of possible
damage, with tips on how to prevent them.

Etching Caused by Acid Rain or
Industrial Fallout

Occurrence

Industrial pollutants and vehicle emissions
drift into the air and mix with rain or dew
to form acids. These acids can settle on a
vehicle's finish. As the water evaporates,
the acid becomes concentrated and can
damage the finish.
And the longer the acid remains on the
surface, the greater the chance is for
damage.

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
suspect that acid rain has settled on your
vehicle's finish.

Damage Caused by Bird Dropping,
Insects, or Tree Sap

Occurrence

Bird droppings contain acids. If these are
not removed they can eat away the clear
and color base coat of the vehicle's
paintwork.

When insects stick to the paint surface and
decompose, corrosive compounds form.
These can erode the clear and color base
coat of the vehicle's paintwork if they are
not removed.

Tree sap will harden and adhere
permanently to the paint finish. If you
scratch the sap off while it is hard, some
vehicle paint could come off with it.

Prevention

It is necessary to have your Mazda washed
and waxed to preserve its finish according
to the instructions in this section. This
should be done as soon as possible.

Bird droppings can be removed with a soft
sponge and water. If you are traveling and
these are not available, a moistened tissue
may also take care of the problem. The
cleaned area should be waxed according to
the instructions in this section.
Insects and tree sap are best removed with
a soft sponge and water or a commercially
available chemical cleaner.

Another method is to cover the affected
area with dampened newspaper for one to
two hours. After removing the newspaper,
rinse off the loosened debris with water.

Maintenance and Care

Appearance Care

6-63

Mazda3_8GE4-EA-17F_Edition1

2017-4-7 11:59:21

Water Marks

Occurrence

Rain, fog, dew, and even tap water can
contain harmful minerals such as salt and
lime. If moisture containing these minerals
settles on the vehicle and 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.

Paint Chipping

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

When the wiper lever is in the

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

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.

Maintenance and Care

Appearance Care

6-64

Mazda3_8GE4-EA-17F_Edition1

2017-4-7 11:59:21

Do not spray water in the engine

compartment. Otherwise, it could result
in engine-starting problems or damage
to electrical parts.

When washing and waxing the vehicle,

be careful not to apply excessive force to
any single area of the vehicle roof or the
antenna. Otherwise, you could dent the
vehicle or damage the antenna.

To help protect the finish from rust and
deterioration, wash your Mazda
thoroughly and frequently, at least once a
month, with lukewarm or cold water.

If the vehicle is washed improperly, the
paint surface could be scratched. Here are
some examples of how scratching could
occur.

Scratches occur on the paint surface when:



The vehicle is washed without first
rinsing off dirt and other foreign matter.



The vehicle is washed with a rough, dry,
or dirty cloth.



The vehicle is washed at a car wash that
uses brushes that are dirty or too stiff.



Cleansers or wax containing abrasives
are used.

NOTE



Mazda is not responsible for scratches
caused by automatic car washes or
improper washing.



Scratches are more noticeable on
vehicles with darker paint finishes.

To minimize scratches on the vehicle's
paint finish:



Rinse off any dirt or other foreign matter
using lukewarm or cold water before
washing.



Use plenty of lukewarm or cold water
and a soft cloth when washing the
vehicle. Do not use a nylon cloth.



Rub gently when washing or drying the
vehicle.



Take your vehicle only to a car wash
that keeps its brushes well maintained.



Do not use abrasive cleansers or wax
that contain abrasives.

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 damage the protective
coating; also, cleaners and detergents
may discolor or deteriorate the paint.

Pay special attention to removing salt, dirt,
mud, and other foreign material from the
underside of the fenders, and make sure
the drain holes in the lower edges of the
doors and rocker panels are clean.

Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits can
damage the finish if not removed
immediately. When prompt washing with
plain water is ineffective, use a mild soap
made for use on vehicles.

Maintenance and Care

Appearance Care

6-65

Mazda3_8GE4-EA-17F_Edition1

2017-4-7 11:59:21

Thoroughly rinse off all soap with
lukewarm or cold water. Do not allow
soap to dry on the finish.

After washing the vehicle, dry it with a
clean chamois to prevent water spots from
forming.

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.

When using an automatic car wash



Retract the door mirrors.



The automatic car wash brushes could
reduce the paint lustre or hasten paint
deterioration.

When using a high water pressure car
wash

High water temperature and high water
pressure car washers are available
depending on the type of car wash
machine. If the car washer nozzle is put
too close to the vehicle, the force of the
spray could damage or deform the
molding, affect the sealability of parts, and
allow water to penetrate the interior. Keep
a sufficient space (30 cm (12 in) or more)
between the nozzle and the vehicle. In
addition, do not spend too much time
spraying the same area of the vehicle, and
be very careful when spraying between
gaps in doors and around windows.

Waxing

Your vehicle needs to be waxed when
water no longer beads on the finish.
Always wash and dry the vehicle before
waxing it. In addition to the vehicle body,
wax the metal trim to maintain its luster.

1. Use wax which contains no abrasives.

Waxes containing abrasive will remove
paint and could damage bright metal
parts.

2. Use a good grade of natural wax for

metallic, mica, and solid colors.

3. When waxing, coat evenly with the

sponge supplied or a soft cloth.

4. Wipe off the wax with a soft cloth.

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.

▼ 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.

Spraying water into the vehicle cabin is
dangerous as electrical devices such as the
audio and switches could get wet resulting
in a malfunction or vehicle fire.

NOTE



Do not wipe the interior using alcohol,
chlorine bleach, or organic solvents
such as thinner, benzene, and gasoline.
Otherwise, it may cause discoloration or
stains.



Rubbing hard with a stiff brush or cloth
may cause damage.

If the vehicle interior becomes soiled by
any of the following, wipe it off
immediately using a soft cloth.
Leaving it uncleaned could cause
discoloration, stains, cracks, or peeling of
the coating, and it will make it hard to
wipe off later.



Beverage or fragrance



Grease or oil

Soiling

▼ Seat Belt Maintenance

1. Clean the soiled area by lightly

dabbing it with a soft cloth soaked in a
mild detergent (approx. 5%) diluted
with water.

2. Wipe off the remaining detergent using

a cloth soaked in clean water and
wrung out well.

3. Before retracting seat belts which have

been pulled out for cleaning, dry them
off thoroughly and make sure there is
no remaining moisture on them.

WARNING

If a seat belt appears frayed or has
abrasions, have it replaced by an
Authorized Mazda Dealer:
If a seat belts is used under such a
condition, it cannot function at its full
capacity which could result in serious injury
or death.

Use a mild detergent to remove soiling
from a seat belt:
If organic solvents are used for cleaning the
seat belts or they become stained or
bleached, there is the possibility of them
becoming weakened and as a result, they
may not function at their full capacity
which could cause serious injury or death.

NOTE
Clean seat belts diligently if they get dirty.
Leaving them uncleaned will make it
difficult to clean them later, and it may
affect the smooth retracting of the seat
belt.

NOTE



Because genuine leather is a natural
material, its surface is not uniform and
it may have natural scars, scratches,
and wrinkles.



To maintain the quality for as long as
possible, periodical maintenance, about
twice a year, is recommended.



If the leather upholstery comes into
contact with any of the following, clean
it immediately.
Leaving it uncleaned could cause
premature wear, mold, or stains.



Sand or dirt



Grease or oil, such as hand cream



Alcohol, such as in cosmetic or hair
dressing items



If the leather upholstery gets wet,
promptly remove moisture with a dry
cloth. Remaining moisture on the
surface may cause deterioration such as
hardening and shrinkage.



Exposure to direct sunlight for long
periods may cause deterioration and
shrinkage. When parking the car under
direct sunlight for long periods, shade
the interior using sunshades.
