Owner MaintenancePrecautions
▼Owner Maintenance Precautions
The owner or a qualified service
technician should make these vehicle
inspections at the i
ndicated 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
6-19)
Engine coolant level (page 6-17)
Engine oil level (page 6-16)
Washer fluid lev el (page 6-19)
At Least Monthly
Tire inflation pressures (page 6-31)
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 6-17)
Engine oil (page 6-16)

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 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 disp ose 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.
WA R N I N G
Do not perform maintenance work if you
lack sufficient knowledge and experience
or the proper tools and equipment to do
the work. Have maintenance work done by
a qualified technician:
Performing maintenance work on a vehicle
is dangerous if not done properly. You can
be seriously injured while performing some
maintenance procedures.

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 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.

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
Severe braking

After rotation, inflate all tire pressures to
specification (page 9- 9) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial tires
that have an asymmetrical tread pattern or
studs only from front to rear, not from side
to side. Tire performance will be reduced if
rotated from side to side.
