Roller Sun Blind

Roller sun blinds are available as an option for the rear window and rear side windows. The roller sun blinds can be raised and lowered electrically.

The switch for the roller sun blind on the rear window is located in the driver's door switch cluster. The footwell module detects the switch status via the LIN-bus. When the button is pressed, the footwell module issues the operational request via the K-CAN2. The complete control and function monitoring facility is integrated in the junction box electronics. The junction box electronics therefore executes the operational request.

Every time the roller sun blinds are operated, their positions are stored in the junction box electronics.

Other operating points are located in the armrests on the rear doors. The switches are located next to the switches for the power windows.

Three switches are provided in each armrest. The switches are:

Switch for roller sun blind on rear window
Switch for roller sun blind on left side window
Switch for roller sun blind on right side window.

The roller sun blinds can be raised and lowered separately with the switches.

Index	Explanation
1	Power window switch
2	Switch for roller sun blind on left side window
3	Switch for roller sun blind on right side window
4	Switch for roller sun blind on rear window

Each rear door has two roller sun blinds, one for the side window and one for the quarter light.

Both roller sun blinds are raised or lowered by means of an electric motor.

NOTE: The roller sun blinds are raised and lowered completely. They cannot be raised or lowered to an intermediate position.

If a new operational request is sent to the roller sun blinds during their actuation, they will reverse their direction of movement immediately.

The enable for operating the roller sun blinds on the rear doors is linked to the closed window position.

The Car Access System issues the enable for operating the roller sun blinds.

The roller sun blind of the corresponding side window is automatically lowered in response to an operational request to open the side window.

Operation of the roller sun blinds is restricted in the event of undervoltage.

By monitoring the outside temperature and interior temperature, the function "lower" roller sun blind is executed at an interior temperature > 11°C and outside temperature <- 16°C.

The roller sun blinds can be operated as from terminal 15N ON.

NOTE: Operation of the roller sun blinds is disabled when the child safety lock is activated.
