service schedule MAZDA MODEL B2300 TRUCK 2004 Owners Manual (in English)

INTRODUCTION
Be extremely careful to prevent injury to yourself and others and
damage to your vehicle when using this manual for inspection and
maintenance.
If you're unsure about any procedure, we strongly urge you to have a
reliable and qualified service shop perform the work, preferably an
Authorized Mazda Dealer.
Factory-trained Mazda technicians and genuine Mazda parts are best for
your vehicle. Without this expertise and the parts that have been
designed and made especially for your Mazda, inadequate, incomplete,
and insufficient servicing may result in problems. This could lead to
vehicle damage or an accident and injuries.
For expert advice and quality service, consult an Authorized Mazda
Dealer.
The owner should retain evidence that proper maintenance has been
performed as prescribed.
Claims against the warranty resulting from lack of maintenance, as
opposed to defective materials or authorized Mazda workmanship, will
not be honored.
Any auto repair shop using parts equivalent to your Mazda's original
equipment may perform maintenance.But we recommend that it
always be done by an Authorized Mazda Dealer using genuine
Mazda parts.

*4 Refer to vehicle emission control information label for spark plug and
gap specifications.
*5 The California Air Resources Board has determined that the failure to
perform this maintenance item will not nullify the emission warranty nor
limit recall liability prior to completion of the vehicle's useful life.
SCHEDULE II Ð SPECIAL OPERATING CONDITIONS
If your driving habitsFREQUENTLYinclude one or more of the
following conditions:
²Short trips of less than 10 miles (16 km) when outside temperatures
remain below freezing.
²Towing a trailer, or carrying maximum loads.
²Operating in severe dust conditions.
²Operating duringhot weatherin stop-and-go ªrush hourº traffic.
²Extensive idling, such as police, taxi or door-to-door delivery service.
²High speed operation with a fully loaded vehicle (max. GVW).
²Off-road operation
Change ENGINE OIL AND OIL FILTER every 3 months or 3,000 miles
(4,800 km) whichever occurs first.
NOTE:Idling the engine for extended periods will accumulate more
hours of use on your vehicle than is actually indicated by the mileage
odometer. Consequently, the odometer reading can be often misleading
when determining the right time to change your engine oil and filter. If
you are using your vehicle in a manner which allows it to remain
stationary while the engine is running for long periods (door-to-door
delivery, taxi, police, power/utility company trucks, or similar duty), then
Mazda recommends you increase the frequency of oil and filter changes
to an interval equivalent to 200 ENGINE HOURS or use. Since most
vehicles are not equipped with hour-meters, it may be necessary for you
to approximate your idle time and plan oil/filter changes accordingly.

BATTERY
Your vehicle is equipped with a
Mazda maintenance-free battery
which normally does not require
additional water during its life of
service.
However, for severe usage or in high temperature climates, check the
battery electrolyte level. Refer to the service maintenance section for the
service interval schedules.
Keep the electrolyte level in each cell up to the ªlevel indicatorº.
Do not overfill the battery cells.
If possible, try to only fill the battery cells with distilled water. If the
battery needs water often, have the charging system checked.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
WARNING: Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames,
sparks or lighted substances to come near the battery. When
working near the battery, always shield your face and protect
your eyes. Always provide proper ventilation.

FFV engine (if equipped)
Your vehicle is designed to use (E85) Fuel Ethanol, ªRegularº unleaded
gasoline or any percentage of the two fuels combined.
U.S. government regulations require fuel ethanol dispensing
pumps to have a small, square, orange and black label with the
common abbreviation or the appropriate percentage for that
region. Use of other fuels such as Fuel Methanol may cause
powertrain damage, a loss of vehicle performance, and your
warranty may be invalidated.
Fuel quality
Many of the world's automakers approved the World-wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-wide Fuel Charter.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Unleaded Gasoline engines
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº unleaded
gasoline. ªPremiumº unleaded gasoline is not recommended (particularly
in the United States) because it may cause these problems to become
more pronounced. If the problems persist, see your authorized Mazda
dealership.
FFV engine (if equipped)
Your FFV will operate well on ordinary ªRegularº unleaded gasoline, but
only the highest quality fuel ethanol will provide the same level of
protection and performance. To identify if your vehicle is an FFV, check
your VIN or the label on the inside of your fuel filler door. When
checking the VIN, look for the engine type identifier (8th character). If
your vehicle is an FFV, then the character will be labeled as a ªV.º
If you operate your vehicle 50% or more of the time on ethanol, you
should follow a different maintenance schedule. See theService
Maintenance Sectionfor more information.

²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle service maintenance section.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Using fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
