1. Position the vehicle on level ground.
2. Warm up the engine to normal operating temperature.
3. Stop the engine and wait for 5 min.
4. Verify that the oil level is between the L and F marks on the dipstick and check the engine oil condition.
•If the oil level is below the L mark, add engine oil. (See D–8 ENGINE OIL REPLACEMENT.)

Warning
•Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the
engine oil have cooled.
•A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall,
causing death or serious injury. Never work around or under a lifted vehicle if it is not securely
supported on safety stands.
•Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your
skin by washing with soap and water immediately after working with engine oil.
Caution
•In case you spill engine oil on the front pipe, wipe it off completely. If you fail to wipe the spilled
oil, it will produce fumes because of the heat.
1. Position the vehicle on level ground.
2. Remove the the oil filler cap.
3. Remove the under cover.
4. Remove the oil pan drain plug.
5. Drain the engine oil into a container.
6. Install the oil pan drain plug with a new the washer.
Tightening torque
12—17 N·m {1.2—1.8 kgf·m, 9—13 ft·lbf}
Note
•The amount of residual oil in the engine can vary with the replacement method, oil temperature, etc. Verify
the oil level after engine oil replacement.
7. Refill the engine oil with the specified type and amount, then install the oil filler cap.

Automatic Transaxle Fluid (ATF) Level Inspection
Caution
•The ATF amount varies according to ATF's temperature. Therefore, when checking the ATF level or
replacing the ATF, use a thermometer to measure the temperature then adjust the ATF amount to
the specified level according to the specified temperature.
1. Park the vehicle on level ground.
2. Apply the parking brake and position wheel chocks securely to prevent the vehicle from rolling.
3. Adjust the length of the thermistor probe measure to the measure same as the dipstick and hold the probe with
a paper holder.
4. Insert into the filler tube and measure the
temperature.
5. Warm up the engine until the ATF reaches (60—
70 °C {140—158 °F}).
Caution
•Do not warm the transaxle by performing
stalls. This will damage the torque
converter.
Note
•In some cases it may be necessary to
inspect the ATF in the cool range 15—25 °C
{59—77 °F} before warming up the engine.
6. While depressing the brake pedal, shift the selector lever to each range (P—M), pausing momentarily in each
range.
7. Shift back to P position.
Note
•If the ATF level is too high or too low in hot condition, the following problems may be the cause.
8. While the engine is idling, verify that the ATF level
is in the HOT (65 °C {149 °F}) range. Add the
ATF specified type of, if necessary. (See K2–80

Warning
•When the transaxle and ATF are hot, they can badly burn you. Turn off the engine and wait until
they are cool before changing the ATF.
1. Remove the oil dipstick.
2. Remove the oil drain plug and washer.
3. Drain the ATF into a container.
4. Install a new washer and the drain plug.
Tightening torque
39—54 N·m {3.9—5.6 kgf·m, 29—40 ft·lbf}
5. Add the specified type of ATF through the oil filler
tube, until ATF level reaches lower notch of

TRANSAXLE RANGE (TR) SWITCH INSPECTIONA6E571419440201
Note
•Input signals of the TR switch can be inspected with a WDS or equivalent. (See K2–90 TCM
INSPECTION.)
Inspection of Operation
1. Verify that the starter operates only with the ignition switch at the START position and the selector lever in P
and N positions.
•If not as specified, inspect for continuity at the TR switch. (See K2–80 Inspection of Continuity.)
2. Verify that the back-up lights illuminate when shifted to R position with the ignition switch at the ON position.
•If not as specified, inspect for continuity at the TR switch.
Inspection of Continuity
1. Disconnect the TR switch connector.
2. Inspect for continuity at the TR switch.
•If not as specified, adjust the TR switch, then
reinspect the TR switch. (See K2–83

Mazda6 (GG), except for the following features. (See Mazda6 Training Manual 3359-1*-02C.)
• Due to the addition of the MZR-CD (RF Turbo) engine, a gear-driven power steering oil pump has been
adopted. The operation of the oil pump is the same as that of the current Mazda6 (GG).
• The disassembly/assembly procedures for the steering gear and linkage of the newly equipped MZR-CD (RF
