The tilt/sliding sunroof is equipped with the express operation and automatic reversal function. If in express operation mode the tilt/sliding sunroof encounters an obstruction that blocks its path, the automatic reversal function will stop the tilt/sliding sunroof and open it slightly. The tilt/sliding sunroof operates differently when the sunroof switch is pressed and held. See the "Closing when the tilt/sliding sunroof is blocked" section for details. The opening/closing procedure of the tilt/ sliding sunroof can be immediately halted by releasing the sunroof switch or, if the sunroof switch was moved past the resistance point and released, by moving the sunroof switch in any direction. G Observe Safety notes, see page 66. G Warning! The tilt/sliding sunroof is made out of glass. In the event of an accident, the glass may shatter. This may result in an opening in the roof. In a vehicle rollover, occupants not wearing their seat belts or not wearing them properly may be thrown out of the opening. Such an opening also presents a potential for injury for occupants wearing their seat belts properly as entire body parts or portions of them may protrude from the passenger compartment. ! To avoid damaging the seals, do not transport any objects with sharp edges which can stick out of the tilt/sliding sunroof. Do not open the tilt/sliding sunroof if there is snow or ice on the roof, as this could result in malfunctions. If you cannot open or close the tilt/sliding sunroof due to a malfunction contact Roadside Assistance or an authorized Mercedes-Benz Center. 200
