May 21, 1999
Title:
MOONROOF PANEL WIND NOISE
Models:
'99 RX 300
Introduction
To reduce the air rushing noise from the roof wind deflector panel, the following two production changes have been made:
Change # 1
The deflector panel protrusion from the roof panel has been decreased from 31 mm to 18 mm. Also, to reduce wind throb due to the change described above, the electric stop position of the sliding roof has been relocated 45 mm forward from the previous position. The sliding roof drive gear assembly is now programmed with 2 stops. The first at 45 mm before fully open and the second at the fully open position.
NOTE:
When the Moonroof Switch is pushed a second time, the sliding roof will fully open.
Change # 2
The holes in the deflector panel have been discontinued.
