POSSIBLE CAUSE

INSPECTION PROCEDURE
1. Drive the vehicle with the panoramic front glass closed. Check if the rattling or clicking is coming from the back corners
of the front glass.
•
If the noise is coming from this area, go to REPAIR PROCEDURE A.
•
If the noise is not coming from this area, this bulletin does not apply. Continue with normal system
troubleshooting.
REPAIR PROCEDURE A
1. Remove the front glass. See the service information.
NOTE
You will need to slightly open the glass to access the bolts.
2. Once the glass is removed, press the panoramic glass roof switch to the closed position.
3. Locate the mechanism arm, as shown below, on the side where you heard the noise. Then, lightly wiggle the rear
portion of that arm enough so it contacts the curve on slider. Do this on both sides of the panoramic glass roof.
•
If you hear a clicking from that area, go to step 4.
•
If you do not hear a clicking from that area, continue with normal system troubleshooting
Page 3 of 13
4. Move the panoramic roof switch to the full tilt position, and check the gap between the curve on slider and the
mechanism bracket. Record the gap as a starting point.
5. Use flat nose pliers to grip the mechanism arm and the metal lip of the panoramic roof frame. Use a screwdriver to peel
back the seal on the panoramic roof.
NOTES
•
Apply tape to the contact surface of the pliers as shown. This will prevent scratching of the panoramic roof frame.
Page 4 of 13
•
Use the radius in the mechanism arm as a reference point. Grip the mechanism arm and the panoramic roof frame
lip right where the bend in the mechanism arm ends.
6. After properly inserting the pliers, squeeze them to bend the arm away from the center of the vehicle. Make sure the
gap measured in step 4 is increased by 1 to 2 mm.
7. Measure the gap again as shown in step 6 to verify the change in the gap.
8. Install the panoramic glass using the original bolts, and test-drive the vehicle with the panoramic roof closed. Make sure
the rattling or clicking is gone.
•
If the noise is gone, the procedure is complete. Replace the original panoramic roof glass bolts with the new bolts.
•
If you still hear the noise, go to REPAIR PROCEDURE B – REPLACE PANORAMIC GLASS ROOF for replacement
of the panoramic roof frame.
