Hydraulic system, filling and bleeding
NOTE:
- The electro-hydraulic convertible top operation involves a closed hydraulic system. Generally, filling is necessary after a loss of oil (accident, leaks, etc.).
- Due to the lift and displacement effect of the pistons in the hydraulic cylinders, the hydraulic system must be filled when the convertible top is stored in the compartment.
- The convertible top must be moved with electro-hydraulic operation.
CAUTION:
Do not fill system above "MAX" marking as the pressure in the system can become so great that damage can result.
Filling
- Remove luggage compartment trim →
- 70 - INTERIOR TRIM
- 70 - INTERIOR TRIM for BODY INTERIOR - CABRIOLET
- 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
NOTE:
- Hydraulic system is self-bleeding. The system is bled after opening and closing the convertible top several times.
- Start the engine.
- Close and open the convertible top 4 - 5 times with electro-hydraulic operation.
- The convertible top must move smoothly and without jerking.
- Check oil level in oil reservoir - 2 - when convertible top is stored in compartment.
- Oil level must be between "MIN" and "MAX" markings.
- Top off hydraulic oil if necessary.
