112 UNDERSTANDING THE FEATURES OF YOUR VEHICLE POWER SUNROOF - IF EQUIPPED The sunroof is electrically operated from a switch located in the overhead console. To operate the sunroof, the ignition switch must be in the ON or ACC position. The sunroof has "Manual" and "Express Open" modes of operation when opening. Express Open Mode To open the sunroof in the Express Open mode, press the switch rearward for less than one second. This causes the sunroof glass to automatically retract and stop at the full open position. This glass position provides the largest possible opening while minimizing low-speed wind buffeting. If wind buffeting does occur, adjusting the sunroof glass position may reduce the intensity of the buffeting. Manual Open Mode The sunroof can also be opened by pressing and holding the switch rearward. Once the switch is held rearward for more than one second, releasing the switch at any time during travel will cause the sunroof to stop at the current position.
