To guarantee a high level of safety, roof movement is accompanied, depending on the equipment variant, by
optical, acoustic and/or text displays/indications. The acoustic indication is a gong, which is sounded once.

Note for vehicles in North America.
During convertible roof movement, a gong is sounded several times here. Reaching the relevant
end position is indicated via the single gong, as in the other countries.

Sensors and hydraulic system
The function of the CSC roof involves complex
interaction between the roof hydraulics and roof
sensors. As described above, the entire roof
movement sequence, with the exception of the sliding
roof module, is carried out via 8 hydraulic cylinders,
which are actuated in pairs by a hydraulic unit. This
actuation is carried out via three solenoid valves in
the hydraulic unit's valve block.

Hydraulic cylinders:
1 In the left main hinge
2 In the left roof side member (C-pillar)
3 In the left rear lid hinge
4 In the left rear lid securing frame
5 In the right main hinge
6 In the right roof side member (C-pillar)
7 In the right rear lid hinge
8 In the right rear lid securing frame

So that the roof control system can monitor the current
positions of all moving assemblies, the roof system is
equipped with 12 Hall senders. A microswitch in the
luggage compartment registers the correct position of
the luggage cover.
A temperature sensor on the hydraulic pump
monitors the temperature of the pump drive.

Timeouts, which indicate failure of the roof function
due to
- a leak in the hydraulic system,
-mechanical damage,
- blocked movements,
- implausible convertible roof position messages or
- communication faults between the linked
control units
are additionally integrated into the roof control
electronics.

G557 Front sender for position of right roof member
G558 Sender for left roof member locked
G559 Sender for right roof member locked
G560 Left sender for rear window frame locked
G561 Right sender for rear window frame locked
G562 Sender for rear window frame open
G563 Left sender for rear shelf locked
G564 Right sender for rear shelf locked
G565 Sender for roof stowed
G566 Sender for left roof member flap open
G567 Sender for right roof member flap open
These timeouts also serve to protect the system, etc.,
by limiting convertible roof operation following
continuous operation or stoppage in an intermediate
position for 8 minutes.
