Hatch operation
The sunroof can only operate when the ignition switch is in position I or II. In addition, the sunroof operates for 40 seconds after the ignition is switched off, provided that the driver's or passenger's door is not opened. One-touch operation of the sunroof is not possible during these 40 seconds.
The electric motor has a microswitch and a Hall sensor. Two gears on the electric motor shaft press the microswitch every 13 revolutions of the shaft. When the microswitch is triggered, the hatch controller registers an open circuit signal. Thus, the controller determines the exact position of the hatch based on signals from the microswitch and the Hall sensor. The Hall sensor is also responsible for the operation of the trauma safety function.
If the safety function is activated during closing, the sunroof panel moves back 200 mm or as far as possible. A Hall sensor located in the sunroof electric drive monitors the engine speed and if the speed falls below a set limit (this is a sign of seizure), the polarity of the power supply switches and the motor shaft begins to rotate in the opposite direction. In an emergency, the safety function can be cancelled by holding the switch in the closed position.
Raising the hatch panel
When the sunroof is closed, pressing the top of the rocker switch causes the sunroof motor to "lift" the rear of the sunroof. The motor will raise the sunroof as long as the switch is held down or until the sunroof reaches its end position. The sunroof can be stopped at any intermediate position by releasing the switch before the panel reaches its end position. A single short press (from 0.5 to 1 second) the switch automatically raises the hatch panel to its extreme position.
When a request is received to raise the hatch, the cables pull the guides back, moving the panel attachment points along the trajectory of installing the hatch in the tilt position.
If the sunroof is raised, it can be lowered by pressing the bottom of the rocker switch. The motor continues to run as long as the switch is pressed or until the panel is completely lowered. The sunroof can be stopped at any intermediate position by releasing the switch before the panel reaches its lowest position.
Opening (shift)
When the sunroof is raised, pressing the top of the rocker switch causes the sunroof panel to lower and retract. A single, short press (from 0.5 to 1 second) the switch automatically moves the sunroof panel to the fully open position. When the panel is moved back, a deflector is automatically raised at the front of the sunroof opening, designed to reduce aerodynamic noise.
When a request to open (slide) is received, the cables pull the glass panel by its fasteners, sliding it back into the ceiling trim.
When the sunroof panel is partially or fully open, pressing the bottom of the switch closes the sunroof panel. A single short press (from 0.5 to 1 second) the switch automatically moves the hatch panel to the extreme tilt position.
If only partial opening or closing is required, then short-term (less than 0.5 seconds) pressing the switch in any direction will stop the panel from moving. If you want to resume movement in any direction, pressing the switch will start the panel moving.
The hatch system has a safety feature that prevents the hatch from closing when an obstacle is detected. When an obstacle is detected, the electric drive automatically moves the panel back 200 mm or as far as possible. Once the obstacle is removed, the panel can be closed in the usual way.
Disconnecting the battery
If the battery is disconnected, the one-touch and safety functions will be unavailable. To begin the sunroof calibration procedure, press the bottom of the switch for 20 seconds. The sunroof panel performs a full cycle of movements and "learns" the parameters required for one-touch control and the safety function again. Until the sunroof calibration is complete, it can be moved manually.
