water is entering car through headliner.
- The sunroof panel should be adjusted under the following cir-
cumstances:
Sunroof misaligned with roof.
Sunroof does not close squarely.
* Wind noise at high speeds (sunroof closed).
Sunroof has been removed.
For correct sunroof alignment:
Sunroof must be fully closed.
Gap must be even all around edge of sunroof.
Front of sunroof must be flush to
1 mm (0.04 in.) below sur-
face of roof.
. Rear of sunroof must be flush to 1 mm (0.04) above sur-
face of roof.
NOTE-
Use a credit card to measure the gap. The card sllould insert
through the gap with equal resistance all around the perimeter.
