Convertible Top Hydraulic Fluid: Service and Repair

• 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.
