Function
Function
The sliding/tilting sunroof is opened and closed by turning the rotary switch or tilted and closed through pushing and pulling the switch, with ignition switched on.
When the ignition is switched off, the sliding/tilting sunroof can still be opened or closed until the driver door or passenger door is opened.
On the rotary switch there are marks for preset opening positions of the glass panel. It is possible, however, to open the sunroof in any position by turning the switch clockwise.
   
Opening the sliding/tilting sunroof to switch position -1-, the so called comfort position, largely reduces wind noises that can occur in switch position -2-.
Opening/closing the sliding/tilting sunroof is carried out by actuation of the switch, i.e. pressing or pulling, or until the respective end position of the glass panel is reached.
The sliding/tilting sunroof is equipped with a force limitation (anti-trap) mechanism for the sliding function. If the sunroof encounters an obstruction while closing, it will open automatically.
As of week 32 1998, a new motor and rotary switch are installed. On models built from this date, the glass panel can also be tilted open and closed using the rotary switch.
In addition, the glass panel is closed by pressing and holding the rotary switch.
  Note
The motor and switch can only be identified by the new part numbers and should not be installed with older type components.
In addition, there is an emergency closure function. If problems occur during closure, the sunroof can be forced shut by pressing the pre-selector switch, which must be in the “sunroof closed” position.
During the emergency closure function, the force limitation mechanism is deactivated.
The sliding/tilting sunroof drive mechanism is protected against overheating by a time limitation factor. The protective mechanism activates when the sunroof is operated continuously for approx. 2 minutes. It is functional again once a predetermined cooling down phase has elapsed.
