qAdvanced Key Maintenance
CAUTION
Ø Make sure the battery is installed
with the correct pole facing
upward. Battery leakage could
occur if it is not installed correctly.
Ø When replacing the battery, be
careful not to bend the electrical
terminals or get oil on them. Also
be careful not to get dirt in the
transmitter as it could be
damaged.
Ø There is the danger of explosion if
the battery is not correctly
replaced.
Ø Replace only with the same type
battery (CR2025 or equivalent).
Ø Dispose of used batteries
according to the following
instructions.
ØInsulate the plus and minus
terminals of the battery using
cellophane or equivalent tape.
ØNever disassemble.
ØNever throw the battery into
fire or water.
ØNever deform or crush.
The following conditions indicate that the
battery power is low:
lThe KEY indicator light (green) flashes
in the instrument cluster when the
engine is turned off.
lThe system does not operate and the
operation indicator light on the
transmitter does not flash when the
buttons are pressed.
lThe system's operational range is
reduced. Replacing the battery at an Authorized
Mazda Dealer is recommended to prevent
damage to the advanced key. If replacing
the battery by yourself, follow the
instruction below.
Replacing the advanced key battery
1. Pull out the auxiliary key.
2. Release the cap using a flathead
screwdriver, then rotate and remove the

3. Install the lug nuts with the bevelededge inward; tighten them by hand.
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 and lower the vehicle. Use the lug
wrench to tighten the nuts in the order
shown.
If you're unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.

(9 ― 12, 65 ―87)
WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off. This could result
in loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration: Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the
stud, which could cause the wheel to
slip off and cause an accident.
5. Check the inflation pressure. Refer to the specification charts on page 10-6.
WARNING
Do not drive with any tires that have
incorrect air pressure: Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
NOTE
To prevent the jack and tool from rattling, store
them properly.

Engine Oil
CAUTION
Do not use either synthetic or semi-
synthetic motor oil. Otherwise engine
starting performance could worsen.
NOTE
lChanging the engine oil should be done by
an Authorized Mazda Dealer.
lThe Mazda RX-8 requires regular checking
of the engine oil level. The compact, high
performance RENESIS rotary engine in
your vehicle consumes a small amount of
engine oil due to its structural design. An
oil pump optimizes the amount of oil
injected to lubricate the rotor seals in the
combustion cycle. Although your vehicle is
equipped with an engine oil level warning
light and an engine oil pressure gauge, it is
best to keep the engine oil level in the range
between full and low by checking the oil
dipstick regularly. Mazda recommends
checking the oil level at every second fuel
filling. The oil consumption of the engine
depends on engine speed and engine load.
Under extreme driving conditions, oil
consumption can be higher.
q Recommended Oil
Use SAE 5W-20 engine oil.
Oil container labels provide important
information.
A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.
U.S.A. and CANADA
(ILSAC)
Only use oils “Certified For Gasoline
Engines ”by the American Petroleum
Institute (API). An oil with this trademark
symbol conforms to the current engine
and emission system protection standards
and fuel economy requirements of the
International Lubricant Standardization
and Approval Committee (ILSAC),
comprised of U.S. and Japanese
automobile manufacturers.

Interior Care
qDashboard Precautions
Prevent caustic solutions such as perfume
and cosmetic oils from contacting the
dashboard. They'll damage and discolor it.
If these solutions get on the dashboard,
wipe them off immediately.
CAUTION
Do not use glazing agents.
Glazing agents contain ingredients
which may cause discoloration,
wrinkling, cracks and peeling.
qCleaning the Upholstery and
Interior Trim
Vinyl
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl with a leather-and-vinyl
cleaner.
Leatherí
Real leather isn't uniform and may have
scars, scratches, and wrinkles. Clean it
with a leather cleaner or mild soap.
If the leather gets wet from rain, remove
the moisture as soon as possible and dry
in a shaded area.
If the seats get wet, promptly remove
moisture with a dry cloth and allow it to
further dry in a shaded area.
If moisture is not removed, it will cause
hardening and shrinkage of the leather.
Do not leave vinyl products on the seats
for long periods as they may affect the
leather quality and coloring.
Fabricí
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner.
Clean it with a mild soap solution good
for upholstery and carpets. Remove fresh
spots immediately with a fabric spot
cleaner.
To keep the fabric looking clean and
fresh, take care of it. Otherwise its color
will be affected, it can be stained easily,
and its fire-resistance may be reduced.
CAUTION
Use only recommended cleaners and
procedures. Others may affect
appearance and fire-resistance.
Suede-like materialí
Stains which are not treated immediately
will be difficult to remove later, and may
cause fading or discoloration.
Remove stains as soon as possible.
To clean, wipe with a soft, damp cloth.
Then buff with a soft, dry cloth.
If stains cannot be removed using plain
water, try wiping with soapy water or a
mild detergent.
CAUTION
Do not clean the suede with leather
cleaner, a detergent, or soap. It will
cause discoloration.
To dry away any water, wipe with a soft,
dry cloth.
CAUTION
Sharp or pointed metal objects can
damage the suede beyond repair.

Piano black panel
The following parts are fitted with panels
that have been treated with a special
coating that resists scratching.
lCenter panellDoor switch panel
When the panel needs to be cleaned, use a
soft cloth to wipe off dirt from the surface.
NOTE
Scratches or nicks on the panels resulting from
the use of a hard brush or cloth may not be
repairable.
q Cleaning the Lap/Shoulder Belt
Webbing
Clean the webbing with a mild soap
solution recommended for upholstery or
carpets. Follow instructions. Don't bleach
or dye the webbing; this may weaken it.
After cleaning the belts, thoroughly dry
the belt webbing and make sure there is
no remaining moisture before retracting
them.
WARNING
Have an Authorized Mazda Dealer
replace damaged seat belts
immediately:
Using damaged seat belts is
dangerous. In a collision, damaged
belts cannot provide adequate
protection.
qCleaning the Window Interiors
If the windows become covered with an
oily, greasy, or waxy film, clean them
with glass cleaner. Follow the directions
on the container.
CAUTION
Ø Don't scrape or scratch the inside
of the rear window. You may
damage the rear window defroster
grid.
Ø When washing the inside rear
window, use a soft cloth
dampened in lukewarm water,
gently wiping the antenna lines.
Use of glass cleaning products
could damage the antenna.
