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.
