Form No. 8R29-EA-02I
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 8-2), several procedure can be done only by a
qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage.
For details, read the separate Mazda Warranty statement provided with the vehicle. If
you’re 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.
Owner Maintenance Precautions
Maintenance Procedures:Performing maintenance work on a vehicle is dangerous if not done properly. You can
be seriously injured while performing some maintenance procedure. If you lack
sufficient knowledge and experience or the proper tools and equipment to do the
work, have it done by a qualified technician.
Running the Engine:
Working under the hood with the engine running is dangerous. It becomes even more
dangerous when you wear jewelry or loose clothing.
Either can become entangled in moving parts and result in injury.
Therefore, if you must run the engine while working under the hood, make certain
that you remove all jewelry (especially rings, bracelets, watches, and necklaces) and
all neckties, scarves, and similar loose clothing before getting near the engine or
cooling fan, with may turn on unexpectedly.
Electrical Fan and Engine Inspection:
Inspecting the engine with the ignition switch in the ON position is dangerous. The
cooling fan could come on unexpectedly even when the engine isn’t running. You
could be seriously injured by the fan. Turn the ignition switch off and remove the key
from the ignition switch when you inspect the engine.

Recommended Oil
Oil container labels provide important
information.
The quality designation SL
or ILSAC

must be on the label.
Engine oil viscosity, or thickness, has an
effect on fuel economy and cold-weather
operation (starting and oil flow).
Low-viscosity engine oils can provide
improved fuel economy and cold-weather
performance.
But high-temperature weather conditions
require higher-viscosity engine oils for
satisfactory lubrication.When choosing an oil, consider the
temperature range your vehicle will
operate in before the next oil change.
Then select the recommended viscosity
from this chart.
Energy conserving oils are recommended.
A chief contribution they make to fuel
economy is reducing the amount of fuel
necessary to overcome engine friction.

Inspecting Engine Oil Level
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 5 minutes for the
oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.

Using oils of viscosity besides those
recommended for specific temperature
ranges could result in engine damage.

5. Pull it out again and examine the level.
It’s OK between MIN and MAX.
But if it’s near or below MIN, add
enough oil to bring the level to MAX.
6. Make sure the O-ring is positioned
properly before reinserting the
dipstick.

Changing Engine Oil and Filter
Change engine oil and filter according to
Scheduled Maintenance (page 8-3).
Please act responsibly—protect the
environment and take used oil to a
recycling facility. Ask your dealer or a
service station for information.
Don’t add engine oil over MAX. This
may cause engine damage.

CAUTION
Handling Used Engine Oil:Continuous contact with used engine
oil is dangerous. It could cause skin
cancer. Always wash with soap and
water immediately after changing oil
and filter.
Remove any oil splatter from the
exhaust manifold, the exhaust pipe and
the shield. Oil left on these areas will
smoke when the engine is running.
