NOTE: The level of ATF varies with fluid temperature. Pay attention to the ATF temperature when checking ATF level.

Raise the ATF temperature by driving a distance of 5 to 10 km (3 to 6 miles). Otherwise, idle the engine to raise ATF temperature to 70 - 80°C (158 - 176°F) on Subaru Select Monitor. Refer to READ CURRENT DATA .
Park the vehicle on a level surface.
After selecting all positions (P, R, N, D), set the select lever in "P" range. Idle the engine for 1 to 2 minutes.
Remove the oil level gauge and wipe it clean.
Reinsert the level gauge all the way. Make sure the level gauge is inserted correctly and in the proper orientation.
Remove the oil level gauge again and make sure that the ATF level is between upper and lower marks of the HOT side.

If the ATF level is below the lower mark, add recommended ATF until the fluid level is between upper and lower marks.
CAUTION:
- Be careful not to exceed the upper level.
- When the transmission is cold, be careful not to add ATF to the upper level on HOT side. Overfilling of ATF may cause oil splashing.
Check the ATF for leaks.
Visually check for leaks in the transmission. If there are leaks, replace the gasket, oil seal, plug or other parts.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
