▼Inspecting Engine Oil Level
NOTE
If the engine oil level warning
indication/warning light turns on,
add 1 L (0.26 US gal, 0.22 Imp gal)
of engine oil.
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.
1. MAX
2. OK
3. MIN
5. Pull it out again and examine the level.
The level is normal if it is between
the MIN and MAX marks.
If it is near or below MIN, add
enough oil to bring the level to
MAX.
CAUTION
Do not overfill the engine oil. This
may cause engine damage.
6. Make sure the O-ring on the
dipstick is positioned properly
before reinserting the dipstick.
7. Reinsert the dipstick fully.

Body Lubrication
▼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
non-freezing lubricant on locks during
cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when
the primary latch is released.
Wiper Blades
▼ Wiper Blades
CAUTION
Hot waxes applied by automatic car
washers have been known to
affect
the wiper's ability to clean windows.
An operation malfunction may occur
or the wiper
effectiveness may be
reduced if a water-repellent coating
is used.
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
When the wiper lever is in the AUTO
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
If the windshield above the rain
sensor is touched.
If the windshield above the rain
sensor is wiped with a cloth.
If the windshield is struck with a
hand or other object.
If the rain sensor is struck with a
hand or other object from inside
the vehicle.
Be careful not to pinch hands or fingers as it may cause injury, or
damage the wipers. When washing
or servicing the vehicle, make sure
the wiper lever is in the OFF
position.
Before lifting the windshield wiper
blades off the windshield, always
follow the procedure for moving the
windshield wiper blades. Otherwise,
a wiper blade, wiper arm, or the
hood could be damaged.

WARNING
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to 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.
When using an automatic car wash
Retract the door mirrors.The automatic car wash brushes
could reduce the paint luster or
hasten paint deterioration.
When using a high water pressure car
wash
High water temperature and high
water pressure car washers are
available depending on the type of car
wash machine. If the car washer nozzle
is put too close to the vehicle, the
force of the spray could damage or
deform the molding, affect the
sealability of parts, and allow water to
penetrate the interior. Keep a sufficient
space (30 cm (12 in) or more)
between the nozzle and the vehicle. In
addition, do not spend too much time
spraying the same area of the vehicle,
and be very careful when spraying
between gaps in doors and around
windows.
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.
Wax containing abrasives will
remove paints 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 does not need it.
▼ 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.

▼Aluminum Wheel Maintenance
A protective coating is provided over
the aluminum wheels. Special care is
needed to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels.
NOTE
Do not use a wire brush or any
abrasive cleaner, polishing
compound, or solvent on aluminum
wheels. They may damage the
coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold water. Also, be
sure to clean the wheels after driving
on dusty or salted roads to help
prevent corrosion.
Avoid washing your vehicle in an
automatic car wash that uses
high-speed or hard brushes.
(20-inch wheel vehicle)
If your aluminum wheels lose luster,
apply wax which contains no
polishing powder.
▼ 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 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.
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.
