General
The roller sunblinds of the side windows in the rear are, in each case, driven by an electric motor and can almost fully cover the side windows. They protect the vehicle occupants in the rear against exposure to too strong sunlight and undesired glances.
The model 167.9 Maybach additionally has roller sunblinds on the side windows in the load compartment.
Function requirements
- Corresponding side window in rear closed
- Circuit 15R ON or control unit power-down active (manual operation)
Control unit power-down
After circuit 15R OFF, the roller sunblinds can still be manually operated for 5 min.
Function
The actuation of the roller sunblind motors can be triggered via the relevant control element in the rear and in the driver's door.
In vehicles with Remote Online, the actuation can also be triggered in a web-based manner via a browser (e. g. tablet/PC/smartphone).
The controls in the rear can be disabled by activating the electrical child safety lock.
The respective roller sunblind is always full extended or retracted. It is not possible to stop in an intermediate position. Every addition request reverses the active actuation.
In normalized state, the roller sunblinds have the following functions:
- Smooth start and stop (to protect the mechanical components and reduce the noise development)
- Automatic reserving function
In the denormalized state, the components are protected against overloads by the blockage detection.
The automatic reversing function and the blockage detection each result in the reversal of the active actuation. The affected roller sunblind is then full extended or retracted.
Additionally on model 167.9 Maybach
Using the pushbutton switch in the rear doors and the driver's door, the roller sunblinds of the side windows in the load compartment can also be actuated.
When the side window is closed, briefly pull the respective button on the roller sunblind to be closed; to open it, briefly press it.
The automatic operation cannot be paused by actuating again.
