Owner Maintenance Precautions
The owner or a qualified service technician should make these v ehicle inspections at the
indicated intervals to ensure safe and dependable operation.

Bring any problem to the attention of an Authorized Mazda Deale r or qualified service
technician as soon as possible.
When Refueling
Brake fluid level (page 6-23)
Engine coolant level (page 6-22)
Engine oil level (page 6-21)
Washer fluid lev el (page 6-24)
At Least Monthly
Tire inflation pressures (page 6-36)
At Least Twice a Year (For Example, Every Spring and Fall)
You can do the following scheduled maintenance items if you hav e some mechanical ability
and a few basic tools and if you closely follow the directions in this manual.
Engine coolant (page 6-22)
Engine oil (page 6-20)

Improper or incomplete service may result in problems. This sec tion gives instructions only
for items that are easy to perform.

As explained in the Introducti on (page 6-2), several procedures can be done only by a
qualified service technician with special tools.

Improper owner maintenance during the warranty period may affec t warranty coverage.
Refer to Introduction (page 6-2) for owner's responsibility in protecting your investment.
For details, read the separate Mazda Warranty statement provide d with the vehicle. If you
are unsure about any servicing or maintenance procedure, have it done by an Authorized
Mazda Dealer.

There are strict environmental laws regarding the disposal of waste oil and fluids. Please
dispose of your waste properly and with due regard to the envir onment.

We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized
Mazda Dealer.

Engine Oil
NOTE
Changing the engine oil should be
performed by an Authorized Mazda
Dealer.
Refer to Introduction (page 6-2) for
owner's responsibility in protecting your
investment.
▼Recommended Oil
U.S.A., Canada, and Puerto Rico
Use SAE 5W-30 engine oil.
Mazda Genuine Oil is used in your Mazda
vehicle. Mazda Genuine 5W-30 Oil is
required to achieve optimum fuel
economy.

For maintenance service, Mazda
recommends Genuine Mazda Parts and
Genuine Mazda Premium Oil.

(ILSAC)
Only use SAE 5W-30 oil “Certified For
Gasoline Engines” by the American
Petroleum Institute (API).
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), c
omprised of U.S.
and Japanese automobile manufacturers.

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-7) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.

CX-9_8LJ2-EA-22H_Edition1_old 2022-6-9 13:33:08

▼Tire Inflation Pressure
WA R N I N G
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-7.
Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handl
ing, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
Cold inflation pressure
The cold inflation pressure is the
pressure measured under ambient
temperatures before the vehicle is
driven.
Maximum inflation pressure
The maximum inflation pressure is the
upper limit of the cold inflation pressure
designated by the tire manufacturer.
Recommended inflation pressure
The recommended inflation pressure is
the cold inflation pressure necessary for
maintaining the performance of your
Mazda.
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequen tly needs inflating,
have it inspected.
▼ Tire Rotation
WA R N I N G
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 12,000 km (7,500
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.

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.
▼ Bright-Metal Maintenance
Use tar remover to r
emove road tar and
insects. Never do this with a knife or
similar tool.
To prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high luster.
During 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 p etroleum jelly or
some other protective compound.
CAUTION
Do not 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.
▼ Underbody Maintenance
Road chemicals and s
alt used for ice and
snow removal and solvents used for dust
control may collect on the underbody. If
not removed, they will speed up rusting
and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust
system, even though these parts may be
coated with anti-corrosive material.

Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try also to
do this every month.

Pay special attention to these areas
because they easily hide mud and dirt. It
will do more harm than good to wet
down the road grime without removing
it.

The lower edges of doors, rocker panels,
and frame members have drain holes that
should not be clogged. Water trapped there
will cause rusting.
