3. Remove the drain plug at the bottom of the 

transmission case to drain out the remaining ATF.

Discharge amount: Approx. 2.0 L

4. Install the drain plug with a gasket in between, 

and tighten it to the specified torque.

Tightening torque: 32 

± 2 Nm

5. Pour in new ATF through the oil filler tube.

Amount to add: Approx. 5.5 L

CAUTION

Stop pouring in the ATF once 5.5 L has been 
poured in.
6. Repeat the operation in step 2.
7. Pour in new ATF through the oil filler tube.

Amount to add: Approx. 3.5 L

NOTE: Carry out steps 2 and 7 so that at least 8.0 
L has been discharged from the cooler hose. After 
this, discharge a small quantity of ATF and check 
for contamination. If the ATF is contaminated, 
repeat steps 6 and 7.

8. Connect the hose which was disconnected in step 

1, and then securely re-insert the oil level gauge.

9. Start the engine, and let it run at idle for 1 

− 2 

minutes.

10.Move the selector lever to all positions once, and 

then return it to the N position.

11.Check that the ATF level on the oil level gauge is 

at the COLD mark. If it is not up to this mark, add 
more ATF.

12.Drive the vehicle until the ATF temperature 

reaches the normal temperature (70 

− 80°C), and 

then re-check the ATF level.

 

The ATF level must be between the HOT marks.
NOTE: 

.

1. The COLD mark is for reference only; the HOT 

marks should be used as the standard for 
judgment.

2. Measure ATF temperature using M.U.T.-II/III.

3. Check the oil level referring to the characteris-

tics chart if it takes some time until reaching 
the normal operation temperature of ATF (70 

 

80

°

C.)

13.When ATF is under the specified level, top up 

ATF. When ATF is over the specified level, drain 
the excessive ATF from the drain plug to adjust 
ATF level to the specified level.

14.Securely insert the oil level gauge into the oil filler 

tube.

1. Remove the hose shown in the illustration which 

allows the ATF to flow from the ATF cooler (built 
into the radiator) to the transmission.

2. Start the engine and discharge the ATF.

 

Driving conditions: N range, idling

CAUTION

The engine should be stopped within one minute 
of it being started. If the ATF has all been dis-
charged before this, stop the engine at that point.

Discharge amount: Approx. 3.5 L

3. Pour in new ATF through the oil filler tube.

Amount to add: Approx. 3.5 L

CAUTION

Stop pouring in the ATF once 3.5 L has been 
poured in.
4. Repeat the operation in steps 2 and 3.

NOTE: Carry out steps 2 and 3 so that at least 8.0 
L has been discharged from the cooler hose. After 
this, discharge a small quantity of ATF and check 
for contamination. If the ATF is contaminated, 
repeat steps 2 and 3.

5. Carry out the procedure in "CHANGE 

PROCEDURE" from step 2 onwards.

E3. CHANGE ENGINE OIL

M6020600300109

1. Start the engine and allow it to warm up until the 

temperature of the coolant reaches 80

°C to 90°C.

2. Stop the engine and remove the engine oil filler 

cap.

3. Remove the drain plug to drain oil.

CAUTION

Use care as oil could be hot.

4. Install a new drain plug gasket so that it faces in 

the direction shown in the illustration, and then 
tighten the drain plug to the specified torque.

Tightening torque: 39 

± 5 Nm

5. Refill with specified quantity of engine oil.

Specified Engine Oil
ACEA and API classifications: "ACEA A1, 
A2, A3"/"FOR SERVICE SG" or higher
Total quantity (Includes volume inside oil fil-
ter):

3.3 L <4G1>
4.3 L <4G6>

6. Remove the dipstick from the engine, and check 

whether or not the engine oil level is within the 
range between MAX and MIN.

7. Install the engine oil fiIler cap.
8. Start the engine and run it for a few minutes.
9. Stop the engine and check the oil level.

E4. REPLACE ENGINE OIL FILTER

M6020600400076

1. Start the engine and allow it to warm up until the 

temperature of the coolant reaches 80

°C to 90°C.

2. Remove the engine oil filler cap.
3. Remove the drain plug to drain oil.

CAUTION

the new oil filter.

8. Once the O-ring of the oil filter is touching the 

flange, use the respective tool in the following 
table to tighten to the specified torque.

9. Install the drain plug and refill the engine oil. 
10.Race the engine 2-3 times, and check to be sure 

that no engine oil leaks from installation section of 
the oil filter.
