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, you may need to reprogram the sunroof. 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.

These buttons are used to program and recall memory settings for the driver's seat, throttle and brake pedals, both the driver's and passenger's outside mirror, the radio station presets and the previously used climate control system settings. The settings for these features can be personalized for both driver 1 and driver 2. Driver 1 or driver 2 corresponds to the memory buttons labeled 1 and 2 on the driver's door and the numbers on the back of the remote keyless entry transmitters. 2-88
