Remarks:
•The ignition and fuel systems are highly important to the emission control system and to efficient engine operation. All
inspections and adjustments must be made by an Authorized Mazda Dealer.
•After the prescribed 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.

damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line
Safety Procedure”.
1. Remove the battery.
2. Remove the battery tray.
3. Remove the radiator.
4. Drain the transaxle oil.
5. Remove the P/S oil pump with the oil hose still connected. Position the P/S oil pump so that it is out of the way.
Use wire or rope to secure.
6. Remove the A/C compressor with the pipes still connected. Position the A/C compressor so that it is out of the
way. Use wire or rope to secure.
7. Remove the propeller shaft from the transfer.
8. Remove the joint shaft. (See M–31 JOINT SHAFT (4WD) DISASSEMBLY/ASSEMBLY.)
9. Remove the front drive shaft (LH) from the transaxle. (See M–39 FRONT DRIVE SHAFT (4WD)
DISASSEMBLY/ASSEMBLY.)
10. Remove the air cleaner, intake air duct, accelerator cable and bracket, and vacuum hose.
11. Remove the ATF hose and selector cable.
12. Remove the vacuum hose and heater hose.
13. Disconnect the fuel hose. (See F1–27 Plastic Fuel Hose Removal Note.) (See F1–28 Plastic Fuel Hose
Installation Note.)
14. Disconnect the wiring harness from the engine side.
15. Remove the three way catalyst (TWC). (See F1–30 EXHAUST SYSTEM REMOVAL/INSTALLATION.)
16. Remove in the order indicated in the table.
17. Install in the reverse order of removal.
18. Start the engine and:
•Inspect for the engine oil, engine coolant, transaxle oil and fuel leakage.
