Repair Procedures
Automatic Transmission Fluid (ATF) Level Check
Start the engine to warm up the ATF.
Using KDS, make sure the ATF temperature is between 50 °C and 60°C (122–140°F).
Slowly move the shift lever from the "P" position to the "D" position, then back to the "P" position. Repeat this sequence two times, then move the shift lever to the "P" position.
Raise the vehicle and remove the ATF level plug (A) from the valve body cover.

Check the ATF level.
Normal: ATF flows out in a thin stream.
Excessive (Abnormal): More than 0.9 L of ATF flows out within 2 minutes.
Insufficient (Abnormal): No fluid flow.
Install the ATF level plug (A).
Tightening torque: 22.6–24 N·m

After checking or replacing the ATF level, be sure to wipe off any ATF from the outside of the automatic transmission.
(Make sure that all ATF residue is removed between the automatic transaxle case and the valve body cover.)
