WATER TEST

Check if there are any leaks in the sunroof by the following procedure.

Scheme 75

Scheme 75: WATER TEST
Scheme 75: WATER TEST
  1. Fully close the roof lid glass.
  2. Adjust the water pressure so that water comes out of the hose to a height of approximately 50 cm (19.7 inches) when the hose is held vertically facing upwards.
  3. Hold the end of the hose approximately 30 cm (11.8 inches) above the roof and let the water run onto the weatherstrip for 5 minutes or more.
  4. Check if any water leaks can be found in the room while watering. Even though there are any water leaks around the roof lid glass, it can be acceptable as long as water is caught in the drip area.

Scheme 76: SUNROOF FIT ADJUSTMENT
Scheme 76: SUNROOF FIT ADJUSTMENT
  1. Fully close the sunroof lid glass.
  2. Fully open the sunshade.
  3. Loosen the sunroof lid glass assembly mounting screws. Adjust the sunroof lid glass height by moving the sunroof lid glass assembly along the sunroof lid guide oblong hole so that the clearance between the sunroof lid glass and the vehicle body is even throughout the circumference.
