tow MAZDA MODEL B4000 4WD 2003 Service Manual

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 it describes, 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.
SCHEDULED MAINTENANCE
Schedule I — Normal Driving Conditions/Emission Control
Systems
Follow Schedule I if the vehicle is operated mainly where none of the
following conditions apply. If any do apply follow Schedule II.
• Repeated short-distance driving.
• Driving in dusty conditions.
• Towing a trailer.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extended periods of idling or low-speed operation.
• High-speed operation with a fully loaded vehicle.
• Off-road operation.
NOTE: After the described period, continue to follow the described
maintenance at the recommended intervals.

SCHEDULE II — SPECIAL OPERATING CONDITIONS
If your driving habitsFREQUENTLYinclude one or more of the
following conditions:
• Short trips of less than 10 miles (16 km) when outside temperatures
remain below freezing.
• Towing a trailer, or carrying maximum loads.
• Operating in severe dust conditions.
• Operating during hot weatherin stop-and-go “rush hour” traffic.
• Extensive idling, such as police, taxi or door-to-door delivery service.
• High speed operation with a fully loaded vehicle (max. GVW).
• Off-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.

Maintenance and Specifications
188

•Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster may reduce fuel economy.
• You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
• Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
• Resting your foot on the brake pedal while driving may reduce fuel
economy.
• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
• Use recommended engine oil. Refer to Lubricant specificationsin
this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle service maintenance section.
Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
• Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
• Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
• Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
• Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
