due by illuminating the wrench indicator light in the instrument
cluster. Mazda Genuine 0W-20 oil is required to achieve optimum
performance.

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

Bring any problem to the attention of an Authorized Mazda Dealer or qualified service
technician as soon as possible.
When Refueling
Brake and clutch fluid level (page 6-27)
Engine coolant level (page 6-25)
Engine oil level (page 6-24)
Washer fluid level (page 6-27)
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 have some mechanical ability
and a few basic tools and if you closely follow the directions in this manual.
Engine coolant (page 6-25)
Engine oil (page 6-22)

Improper or incomplete service may result in problems. Th is section gives instructions only
for items that are easy to perform.

As explained in the Introduc tion (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 affect warranty coverage.
Refer to Introduction (page 6-2) for owner' s responsibility in protecting your investment.
For details, read the separate Mazda Warranty statement provided 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 environment.

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

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, handlin g, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
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 frequently 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.
Refer to Scheduled Maintenance on page
6-4.

During rotation, inspect them for correct
balance.

Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
