Open tilting roof, function

Function requirements:

 Circuit 15R ON

 Before it is actuated again, the DBE control unit (N70) recognizes the park position of the tilting/sliding roof control button (N70s1) for t = 50 ms

 No overvoltage or undervoltage

 Overvoltage is present when voltage > 16.5 V. Undervoltage is present when voltage < 9 V.

 Only the manual functions of the front tilting/sliding roof (M12) are available

-----------------------------------------------------------------------------------------

Activation is accomplished by actuating the tilting/sliding roof control button up to the pressure point

The front tilting/sliding roof motor is actuated via the DBE control unit by pressing and holding down the tilting/sliding roof control button upward up to the pressure point (M12m1) and the tilting roof is moved manually to the tilting position (ventilation position).If the tilting/sliding roof control button is released, the tilting roof remains in the current position.In the closed position, the tilting roof is located at the front stop, in the tilting position (ventilation position) it is located at a defined position between the front and rear stops.

-----------------------------------------------------------------------------------------

 The tilting/sliding roof control button must be actuated for t > 50 ms. If the DBE control unit recognizes that the tilting/sliding roof control button is actuated for t  25 s, actuation of the front tilting/sliding roof motor is denormalized and an error is stored. When the tilting/sliding roof control button is actuated again, the DBE control unit must previously recognize the park position of the tilting/sliding roof control button for t = 50 ms.

Lock-up

If lock-up is recognized, the front tilting/sliding roof reverses directions, e.g. the front tilting/sliding roof motor is actuated in the opposite direction and is deactivated after t = 160 ms

Emergency operation

The position is not sensed when the front tilting/sliding roof is actuated with the emergency operationIt is then necessary to "normalize" the front tilting/sliding roof.

Roller sun blind, function

The roller sun blind can be moved toward the front or rear using the handle mounted on the roller sun blind. The roller sun blind remains in the corresponding position. The roller sun blind is automatically rolled up.
