NOTE
If you elect to perform maintenance yourself or have your vehicle serviced at a location
other than an Authorized Mazda Dealer, Mazda requires that all fluids, parts and materials
must meet Mazda standards for durability and performance as described in this manual.

Claims against the warranty resulting from lack of maintenance, as opposed to defective
materials or authorized Mazda wo rkmanship, will not be honored.

Any auto repair shop using parts equivalent to your Mazda's ori ginal equipment may
perform maintenance. But we recommend that it always be done by an Authorized
Mazda Dealer using ge nuine Mazda parts.
Selecting “Maintenance Monitor” enables the system to notify yo u of your vehicle's
approaching inspection/servicing period (page 6-15).

The malfunction diagnosis connector is designed exclusively for connecting the specially
designed device to perform on-board diagnosis.
Do not connect any devices other than the specially designed ma lfunction diagnosis devices
for servicing. If any device othe r than the malfunction diagnosis device is connected, it may
affect the vehicle's electrical devices or lead to damage such as battery depletion.

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 isblown.
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.

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-filler lid is closed
and lock the doors. Otherwise, the
fuel-filler lid may be forcefully opened by
water pressure causing damage to the
vehicle or fuel-filler 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 ar e 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 scratche s 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 brush es 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.

▼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 s uch 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.
