•To ensure efficient operation of the engine and all systems related to emission control, the ignition and fuel systems must
be serviced regularly. It is strongly recommended that all servicing related to these systems be done by an authorized
Mazda Dealer.
•After the described period, continue to follow the described maintenance at the recommended intervals.
•Refer below for a description of items marked* in the maintenance chart.
*1: If 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.
*2: Also inspect and adjust the power steering and air conditioner drive belts, if installed.
*3: If the brakes are used extensively (for example, continuous hard driving or mountain driving) or if the vehicle is
operated in extremely humid climates, change the brake fluid annually.
*4: If the vehicle is operated in very dusty or sandy areas, clean and if necessary, replace the air cleaner element more
often than the recommended intervals.
*5: This is a full function check of electrical systems such as lights, wiper and washer systems (including wiper blades),
and power windows.
*6: If the vehicle is operated under any of the following conditions, change the rear differential oil
every 45,000 km (27,000 miles).
a. Towing a trailer or using a car - top carrier
b. Driving in dusty, sandy or wet condition
c. Extended periods of idling or low speed operation
d. Repeated short trips of less than 16 km (10 miles)
*7: If this component has been submerged in water, the oil should be changed.
