Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Hydraulic Pump
The hydraulic pump is mounted under a bracket in the cargo compartment below the ski hatch. The pump drives all hydraulic cylinders for the roof's function. There is a temperature sensor in the hydraulic pump that reads off the operating temperature of the hydraulic pump. The hydraulic pump is partially controlled depending on the temperature in the hydraulic pump (see the uppermost table below).
| Temperature range | Functionality |
| Less than 90 °C | The Convertible Roof Module (CRM) permits full functionality of the hydraulic pump. |
| 90 °C -120 °C | The Convertible Roof Module (CRM) only permits one roof closure or one load assistance withdrawal. |
| Greater than 120 °C | The Convertible Roof Module (CRM) does not permit any functionality at all. |
The roof's functionality also depends on the outside temperature (see the table below).
| Temperature range | Functionality |
| Less than -9 °C | The Convertible Roof Module (CRM) only permits one roof closure. |
| Less than -11 °C | The Convertible Roof Module (CRM) does not permit any functionality at all. |
