Subaru Forester: Clutch fluid (MT models)
Checking the fluid level

Checking the fluid level
Check the fluid level on the outside of the reservoir. If the level is below “MIN” level mark, add the recommended clutch fluid to “MAX” level mark.
Use only clutch fluid from a sealed container.

Never let clutch fluid contact your eyes because clutch fluid can be harmful to your eyes. If clutch fluid gets in your eyes, immediately flush them thoroughly with clean water.
For safety, when performing this work, wearing eye protection is advisable.

- Clutch fluid absorbs moisture from the air. Any absorbed moisture can cause improper clutch operation.
- If the vehicle requires frequent refilling, there may be a leak. If you suspect a problem, have the vehicle checked at your SUBARU dealer.
- When clutch fluid is added, be careful not to allow any dirt into the tank.
- Never splash the clutch fluid over painted surfaces or rubber parts.
Alcohol contained in the clutch fluid may damage them.
- Be careful not to spill clutch fluid when adding it. If clutch fluid touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. If clutch fluid gets on the exhaust pipe, be sure to wipe it off.
Recommended clutch fluid
Refer to “Fluids”.

Never use different brands of clutch fluid together. Also, avoid mixing DOT 3 and DOT 4 brake fluids even if they are the same brand.
Brake booster
If the brake booster does not operate as described in the following, have it checked by your SUBARU dealer.
1. With the engine off, depress the brake pedal several times, applying the same pedal force each time. The distance the pedal travels should not vary.
2. With the brake pedal depressed, start the engine. The pedal should move slightly down to the floor.
3. With the brake pedal depressed, stop the engine and keep the pedal depressed for 30 seconds. The pedal height should not change.
4. Start the engine again and run for approximately 1 minute then turn it off.
Depress the brake pedal several times to check the brake booster. The brake booster operates properly if the pedal stroke decreases with each depression.
NOTE
For models equipped with the brake
assist system, when you depress the
brake pedal strongly or suddenly, the
following phenomena occur. However,
even though these occur, they do not
indicate any malfunctions, and the
brake assist system is operating properly.
- You might feel that the brake pedal is applied by lighter force and generates a greater braking force.
- You might hear the sound of ABS operating from the engine compartment.
Brake assist is not a system that brings more braking ability to the vehicle beyond its breaking capability.
