Owner Maintenance
FusesYour 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 ReplacementReplacing 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.
6. Reinstall the cover and make sure that
it is securely installed.

6 –61 Maintenance and Care
Appearance Care Maintaining the FinishWashing
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. 
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 hood.
Otherwise, you could dent the vehicle. 
Do not use automatic car washing
machines and car washing devices using
high water pressure. 
Make sure that the fuel lid is closed
and lock the doors. Otherwise, the fuel
lid may be forcefully opened by water
pressure causing damage to the vehicle
or fuel lid.
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.

6 –68 Maintenance and Care
Appearance Care 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. Interior Care WARNING Do not spray water into the vehicle
cabin:
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.
