Owner MaintenancePrecautions
▼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
qualifi
ed service technician as soon as
possible.
When Refueling
Brake and clutch fluid level (page
6-21)
Engine coolant level (page 6-20)Engine oil level (page 6-19)Washer fluid level (page 6-22)
At Least Monthly
Tire in flation pressures (page 6-34)
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 6-20)Engine oil (page 6-19)

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

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

Improper owner maintenance during
the warranty period may a ffect
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
fl uids. 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.
WARNING
Do not perform maintenance work if
you lack su fficient knowledge and
experience or the proper tools and
equipment to do the work. Have
maintenance work done by a
quali fied technician:
Performing maintenance work on a

▼Tire In
flation Pressure
WARNING
Always in flate the tires to the correct
pressure:
Overin flation or underin flation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-10.
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, handling ,
and minimum tire wear.
Refer to the specification charts (page
9-10).
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.
Underin flation 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.
Overin flation 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 in flating, have it inspected.
▼ Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking , rotate the tires periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tire rotation interval.
During rotation, inspect them for
correct balance.

1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.
