SUN ROOF - Description
Description
The sunroof offers extra ventilation for the interior compartment and ensures a rapid air exchange, if required, thus increasing passenger comfort.
The system is operated by a knob, located near the front courtesy light.
The operating logic of the roof is controlled by a specific control unit which receives the signals from the control knob and roof operating motor.
By turning the knob in the direction shown by the arrow, the roof slides open: you can choose between 5 available open positions; to close the roof, return the knob to the central position.
The sunroof has a blind which slides manually; however, it is towed by the roof when the roof is opening; during closure, the blind comes out partially so that the grab handle is accessible.
When the knob is turned in the opposite direction to that shown by the arrow, the rear part of the roof opens upwards: you can choose one of 3 available open positions; to close the roof, return the knob to the central position.
Pressing the knob interrupts any movement (inhibition position).
The roof's control electronics also has an anti-collision function: during roof closure, the movement is stopped and reversed by about 10 cm if - via a Hall-effect sensor located on the engine - an obstacle is detected.
This function can be excluded - for safety reasons - by pressing the knob as described above.
Movement is also disabled when the battery voltage is below 10 V.
The roof is also automatically closed - if left open - via a specific prolonged command (over 4 seconds) sent by the remote control button, if the ignition is off; for more details See E3040 CENTRAL LOCKING.
