When lifting, the headliner retracts several inches. The sunroof can continue to operate after the ignition has been switched off as long as one of the front doors has not been opened.

Mechanically, the sunroofs are similar in design. Some vehicles are equipped with the steel roof while others are equipped with the glass (moon) roof.

The anti-trap feature of the sunroof uses a hall sensor to detect obstructions while the sunroof is closing. The initialization procedure must be carried out to allow the sunroof to operate in the opening direction and allow the anti-trap feature to function. The anti-trap is shut down 4 mm prior to full closed and during the tilt closing function.
