*1Also inspect and adjust the power steering and air conditioner drive belts, if installed.*2Replacement of the timing belt is required at every 100,000 km {60,000 miles}. Failure to replace the timing
belt may result in damage to the engine.
*3If the vehicle is operated under any of the following conditions, change the engine oil and oil filter more often
than recommended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c) Driving for long period in cold temperatures or driving regularly at short distance only.
*4If the vehicle is operated in very dusty or sandy areas, inspect and if necessary, clean or replace the air filter
more often than the recommended intervals.

Recommended Oil
Oil container labels provide important
information.
The quality designation SG, SH, SJ,
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.

recommended for specific temperature
ranges could result in engine damage.

Check the oil level and fill to the F mark if
necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year
—at the beginning of the
winter season —and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.
NOTE
• The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
• Use only specified engine oil (page
10-4).
Engine Coolant
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Don
’t
inspect the coolant system or add
coolant when the engine is hot.
