Hydraulic System, Bleeding and Filling

Hydraulic system, bleeding and filling

Notes:
The convertible top must be fully retracted into the storage compartment when filling the hydraulic system because fluid is displaced by the movement of the hydraulic pistons.
For this reason, the fluid level may be slightly lower when the convertible top is closed.

Bleeding

Note: The hydraulic system is self-bleeding and can be bled by operating it several times.

- Start engine.
- Operate switch to open and close convertible top four to five times.
Hydraulic system will self-bleed when convertible top is opened and closed
Convertible top must open and close smoothly and uniformly

- Check fluid level in sight glass with convertible top open and top off if necessary.

Filling

Note: The convertible top has a closed hydraulic system which normally only needs refilling if it is opened (e.g. to replace components).
