Hydraulic System, Filling and Bleeding

Hydraulic System, Filling and Bleeding

• The electro-hydraulic convertible top operation involves a closed hydraulic system. Generally, filling is necessary after a loss of oil (accident, leaks, etc.).

• Before opening the hydraulic system, open the filler plug on the fluid reservoir to even out the pressure in the system and then close it again to the tightening specification.

• The hydraulic system must be filled when the convertible top is closed due to the lift and displacement effects in the hydraulic cylinders.

• The convertible top must be moved with electro-hydraulic operation.


Do not fill system above "MAX" marking as the pressure in the system can become so great that damage can result.

Filling





- Remove the luggage compartment side trim panel near the hydraulic pump..

- Remove oil filler plug - arrow -.

- Fill Hydraulic Oil (G 004 000) with a fill container until oil level is between "MIN." and "MAX." markings.

Bleeding

• Hydraulic system is self-bleeding. The system is bled after opening and closing the convertible top several times.

- Start the engine.

- Open and close the convertible top five times using the electro-hydraulic actuator.

• The convertible top must move smoothly and without jerking.

- Check fluid level in reservoir - 2 - with the roof closed.

• Oil level must be between "MIN." and "MAX." markings.

- Fill the hydraulic fluid if necessary.

- After the hydraulic fluid is filled, open and close the convertible top five times using the electro-hydraulic actuator.

- Check the fluid level one more time and repeat the procedure if necessary.
