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.

MECHANICAL SYSTEM TESTA6E571401030209Mechanical System Test Preparation
1. Apply the parking brake and use wheel chocks at the front and rear of the wheels.
2. Inspect the engine coolant. (See Section E.)
3. Inspect the engine oil. (See D–8 ENGINE OIL INSPECTION.)
4. Inspect the ATF levels. (See K2–79 Automatic Transaxle Fluid (ATF) Level Inspection.)
5. Inspect the idle speed and ignition timing in P position. (See F1–22 IDLE SPEED INSPECTION (4WD).)
Line Pressure Test
Note
•Line pressure cannot be measured on the JA5AX-EL automatic transaxle. Measure the low clutch
pressure in place of D and M range line pressures. Measure the reverse clutch pressure in place of R
position line pressure.
1. Engine idling.
(1) Perform mechanical system test preparation. (See K2–72 Mechanical System Test Preparation.)
Warning
•Removing the plug when the ATF is hot can be dangerous. Hot ATF can come out of the opening
and badly burn you. Before removing the square-head plug, allow the ATF to cool.
(2) Remove the plug and O-ring shown in the
figure.

Stall Speed Test
1. Perform mechanical system test preparation. (See K2–72 Mechanical System Test Preparation.)
2. Connect a tachometer.
3. Start the engine.
4. Shift the selector lever to D range.
Caution
•Do not maintain WOT in any gear range for more than 5 seconds or transaxle damage will occur.
•If engine speed recorded by the tachometer exceeds maximum specified rpm, release the
accelerator pedal immediately. Clutch or band slippage is indicator.
5. Firmly depress the brake pedal with the left foot, and gently depress the accelerator pedal to the floor (WOT)
with the right.
6. When the engine speed no longer increases, quickly read the engine speed and release the accelerator pedal.
7. Shift the selector the to N position and let the engine idle for 1 minute or more to cool the ATF.
8. Perform stall tests for the remaining ranges and position in the same manner.
