Safety functions

If the slide/tilt sunroof does not reach an end position, the electric motor is switched off after 15 seconds.

The heating of the electric motor is calculated in the SHD control module based on a model. The available temperature signals are the outside temperature and inside temperature (via K-CAN). In addition, there is an electronic thermometer (transistor) on the board of the SHD control module.

In emergency operation, the slide/tilt sunroof can only be moved for 750 milliseconds at a time.

Emergency operation is possible under the following conditions:

• Coding of the SHD control module invalid
• Signal of a Hall sensor implausible
• Initialization incomplete

With an electrical defect, there is an emergency actuating unit for the slide/tilt sunroof. Fold down the cover of the roof operating unit. Place the internal hexagon spanner from the on-board tool kit in the opening at the drive of the slide/tilt sunroof and move the roof in the desired direction.
