Mercedes Benz Workshop Service and Repair Manuals

Location

One cylinder under each of the right and left main bearings of the vario roof.

Task

Raising and lowering the folded vario roof in the trunk.

Design

Single-acting cylinder (rod-side pressure connection).

Function

When pressurized, the hydraulic cylinder rod retracts, lifting the folded vario roof. The load assist is lowered by halting the pressurization.
The folded vario roof moves down into the trunk under its own weight, forcing the hydraulic fluid out of the hydraulic cylinder.
