Wipe off the dipstick. Close the cap and then open it again. The fluid level should be between the MIN and MAX markings. Top up with Pentosin if necessary.
If the fluid level has dropped, carry out the following tests:
- Check the fluid level in the luggage compartment. If the reservoir has overflowed, the clutch slave cylinder is defective and must be replaced.
- Check the pressure accumulator. → 300101 CHECKING CLUTCH BOOSTER CIRCUIT
- Visually check to see if Pentosin is lost at the clutch slave cylinder and steering.
Close the cap carefully.
