Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and reinsert it fully.
Full
OK
Low
5. Pull it out again and examine the level.It's OK between Low and Full.
But if it's near or below Low, add
enough oil to bring the level to Full.
CAUTION
Don't add engine oil over Full. This
may cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
The distance between Low and Full on the
dipstick represents the following:

Power Steering Fluid
qInspecting Power Steering Fluid
Level
CAUTION
To avoid damage to the power
steering pump, don't operate the
vehicle for long periods when the
power steering fluid level is low.
NOTE
Use specified power steering fluid (page 10-4).
Inspect the fluid level in the reservoir at
each engine oil change with the engine off
and cold. Add fluid if necessary; it does
not require periodic changing.
The level must be kept between MIN and
MAX.
Visually examine the lines and hoses for
leaks and damage.
If new fluid is required frequently, consult
an Authorized Mazda Dealer.
Washer Fluid
q Inspecting Washer Fluid Level
WARNING
Use only windshield washer fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the
windshield, affect your visibility, and
could result in an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather: Operating your vehicle in
temperatures below 4 degrees C (40
degrees F) using washer fluid without
anti-freeze protection is dangerous
as it could cause impaired windshield
vision and result in an accident. In
cold weather, always use washer
fluid with anti-freeze protection.
NOTE
State or local regulations may restrict the use
of volatile organic compounds (VOCs), which
are commonly used as anti-freeze agents in
washer fluid. A washer fluid with limited VOC
content should be used only if it provides
adequate freeze resistance for all regions and
climates in which the vehicle will be operated.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
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.

WARNING
Do not replace the xenon fusion bulbs
yourself:Replacing the xenon fusion bulbs
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Consult an Authorized
Mazda Dealer when the replacement
is necessary.
Never touch the glass portion of a
halogen bulb with your bare hands and
always wear eye protection when
handling or working around the bulbs: When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it
will explode and serious injuries
could be caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when
lit.
Always keep halogen bulbs out of the
reach of children: Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb
or breaking it some other way.
qReplacing Exterior Light Bulbs
NOTElTo replace the bulb, contact an Authorized
Mazda Dealer.
lIf the halogen bulb is accidentally touched,
it should be cleaned with rubbing alcohol
before being used.

After washing the vehicle, dry it with a
clean chamois to prevent water spots from
forming.
WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal:Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
Waxing
Your vehicle needs to be waxed when
water no longer beads on the finish.
Always wash and dry the vehicle before
waxing it. In addition to the vehicle body,
wax the metal trim to maintain its luster.
1. Use wax which contains no abrasives.Waxes containing abrasive will remove
paint and could damage bright metal
parts.
2. Use a good grade of natural wax for metallic, mica, and solid colors.
3. When waxing, coat evenly with the sponge supplied or a soft cloth.
4. Wipe off the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and similar
materials will usually also take off the wax.
Rewax these areas even if the rest of the
vehicle doesn't need it.
q Repairing Damage to the Finish
Deep scratches or chips on the finish
should be repaired promptly. Exposed
metal quickly rusts and can lead to major
repairs.
CAUTION
If your Mazda is damaged and needs
metal parts repaired or replaced,
make sure the body shop applies
anti-corrosion materials to all parts,
both repaired and new. This will
prevent them from rusting.
qBright-Metal Maintenance
lUse tar remover to remove road tar and
insects. Never do this with a knife or
similar tool.
lTo prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high luster.
lDuring cold weather or in coastal areas,
cover bright-metal parts with a coating
of wax or preservative heavier than
usual. It would also help to coat them
with noncorrosive petroleum jelly or
some other protective compound.
CAUTION
Don't use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or anodized
aluminum parts. This may result in
damage to the protective coating and
cause discoloration or paint
deterioration.

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 is not 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.
