Automatic Transaxle Fluid (ATF) Level Check

When checking the ATF level, be careful not to allow foreign substance (like dust) to enter through the filler hole.

1.	Remove the air cleaner assembly. G 2.0 MPI (Refer to Engine Mechanical System - "Air Cleaner") G 2.5 GDI (Refer to Engine Mechanical System - "Air Cleaner")

2.	Add 0.7 L of ATF SP-IV through the ATF filler hole after removing the eyebolt (A). [G 2.0 MPI - A6MF1-2] [G 2.5 GDI - A8MF1]

3.	Remove the inhibitor switch. [G 2.0 MPI - A6MF1-2 Only] (Refer to Automatic Transaxle Control System - "Inhibitor Switch")

Start the engine to warm up the ATF.

Do not step on the brake and accelerator simultaneously to warm up the ATF.

5.	Check by using KDS that the temperature of the ATF is between 50°C and 60°C (122-140°F).

Move the shift lever slowly from "P" to "D", then back to "P". Repeat this sequence two times and then move the shift lever to "P" range.

Pause in each range for more than 2 seconds.

7.	Remove the under cover. G 2.0 MPI (Refer to Engine Mechanical System - "Engine Room Under Cover") G 2.5 GDI (Refer to Engine Mechanical System - "Engine Room Under Cover")

Lift the vehicle and remove the ATF level plug (A) from the valve body cover.

When removing the ATF level plug, keep the vehicle on a level ground.

[G 2.0 MPI - A6MF1-2]

[G 2.5 GDI - A8MF1]

Check the ATF level.

Normal : ATF flows out in a thin oil stream.

Excessive : (abnormal): Over 0.9 liters of ATF flows out for 2 minutes.

Insufficient : (abnormal): There is no fluid flow.

If the ATF level is too high or low, follow the instructions below.

•	Excessive: Drain until the ATF flows out in a thin oil stream.

•	Insufficient: Add until the ATF flows out in a thin oil stream.

10.

Install the ATF level plug (A).

The existing ATF level plug O-ring (A) must be replaced with a new one. (Do not reuse it.)

[G 2.5 GDI - A8MF1]

11.

Lower the vehicle and install the eyebolt (A).

Tightening torque :

4.9 - 5.9 N·m (0.5 - 0.6 kgf·m, 3.6 - 4.3 lb·ft)

[G 2.0 MPI - A6MF1-2]

[G 2.5 GDI - A8MF1]

The existing eyebolt O-ring (B) must be replaced with a new one. (Do not reuse it.)

12.	Install the inhibitor switch. [G 2.0 MPI - A6MF1-2 Only] (Refer to Automatic Transaxle Control System - "Inhibitor Switch")

13.	Install the air cleaner assembly. G 2.0 MPI (Refer to Engine Mechanical System - "Air Cleaner") G 2.5 GDI (Refer to Engine Mechanical System - "Air Cleaner")

14.	Install the under cover. G 2.0 MPI (Refer to Engine Mechanical System - "Engine Room Under Cover") G 2.5 GDI (Refer to Engine Mechanical System - "Engine Room Under Cover")
