WARNING
Don't Apply Oil or Grease to Lug
Nuts, Bolts:
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. Do not apply oil or grease
to lug nuts and bolts and do not
tighten the lug nuts beyond the
recommended tightening torque.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.

Engine Oil
NOTE
The 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.
qRecommended 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.

Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
Air Filter
CAUTION
Don't drive without an air filter. This
could result in excessive engine wear.
This air filter may be cleaned with
compressed air and reused, or replaced,
depending on its condition. Unless it is
very dirty, simply shake it to remove
foreign particles. Each time you inspect it,
wipe inside the air cleaner housing with a
damp cloth.
qReplacing the Air Filter
NOTE
If the vehicle is operated in very dusty
or sandy areas, replace the filter more
often than recommended intervals.
1. Make sure the ignition switch is turned
off.
2. Disconnect the electrical connector.

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
Don't 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 center panel and door switch panels
have been treated with a special coating
that resists scratching.
When the panel needs to be cleaned, use a
soft cloth to wipe off dirt from the surface.
NOTE
Scratches or nicks on the center and
door switch panels resulting from the
use of a hard brush or cloth may not be
repairable.
qCleaning 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
Damaged Seat Belt:
Using damaged seat belts is
dangerous. In a collision, damaged
belts cannot provide adequate
protection. Have an Authorized Mazda
Dealer replace damaged belts
immediately.
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
lDon't scrape or scratch the inside of
the rear window. You may damage
the rear window defroster grid.
lWhen 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.
