Sunroof maintenance?

[br1anstorm]

I have a 2002 IS300 Sportcross - but this question is relevant to most, if not all, Lexus models. 

What needs to be done to keep the tilt/slide sunroof working well?

I have always been slightly nervous about sunroofs, fearing that they will get stuck or won't close properly.  I used to own a Merc with a tilt/slide sunroof, and the service manual had very strict instructions about maintaining the mechanism and using only a very special kind of lubricating grease (not WD40 or silicone stuff....) .

I've had my IS300 serviced at a couple of different dealers, but failed to check whether the standard service schedule includes any lubrication of the sunroof slides or checks on the motor.  Does anyone know whether this is part of the service routine?  Is a special kind of grease required, and if so what is it?

Clean out all the drains and use lithium grease on the sunroof rails.
