The sunroof is also equipped with a sunshade which can be pulled forward to block sun rays. If a hand, arm, or other object is blocking the sunroof glass panel as it is closing, the glass panel will stop at the obstruction. After the obstruction is removed, the glass panel can be closed or opened. Use care not to leave the sunroof open for long periods of time as debris may collect in the tracks. If the battery has been recharged, disconnected or is not working, the sunroof may need to be reprogrammed. To do this, start the vehicle and press the forward side of the sunroof button until the glass panel moves to a fully closed position. Release, and press again to move to the vent position which occurs when the sunroof is fully tilted rearward. This will reset the memory and enable the sunroof to function properly. Vehicle Personalization Memory Seat If your vehicle has this feature, the controls for the memory function are located on the driver's door. These buttons are used to program and recall memory settings for the driver's seat, throttle and brake pedals and both the driver's and passenger's outside mirrors. The settings for these features can be saved for up to two drivers. 2-85
