Fuses
Your vehicle's electrical system is
protected by fuses.
If any lights, accessories, or controls don't
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.
qFuse 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. Turn off the ignition switch and other
switches.
2. Remove the cover.
3. Pull the fuse straight out with the fuse puller provided on the inside of the
engine compartment fuse block cover.
4. Inspect the fuse and replace it if it'sblown.
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 CIGAR circuit.
CAUTION
Always replace a fuse with one of the
same rating. Otherwise you may
damage the electric system.

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. Turn off the ignition switch and allother switches.
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 .
Normal
Blown
WARNING
Do not replace the main fuse by
yourself. Have an Authorized Mazda
Dealer perform the replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse is
a high current fuse. Incorrect
replacement could cause an electrical
shock or a short circuit resulting in a
fire.

qAluminum Wheel Maintenanceí
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
NOTE
lDo not use a wire brush or any abrasive
cleaner, polishing compound, or solvent on
aluminum wheels. They may damage the
coating.
lOnly use a mild soap or neutral detergent
and always use a sponge or soft cloth to
clean the wheels.
Rinse thoroughly with lukewarm or cold
water. Also, be sure to clean the wheels
after driving on dusty or salted roads. This
helps prevent corrosion.
lAvoid washing your vehicle in an automatic
car wash that uses high-speed or hard
brushes.
lIf your aluminum wheels lose luster, wax
the wheels.
(With Tire Pressure Monitoring System)
Check special requirements for Tire Pressure
Monitoring System.
Refer to Tires and Wheels on page 5-34.
q Plastic Part Maintenance
lWhen 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.
lIf 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.
lHigh 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.
lDo not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
lIn 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.
