Its 8-32 in the 2000 manual. I cant scan from home so I will quote.

Cleaning Tinted Glass Surfaces:
The tinted heat-reflecting glass has a metal coating on the interior side. To clean the interior side of glass, use plain water or a neutral detergent. Do Not use harsh chemicals. Wipe clean with a soft cloth or paper towel
that is the complete quote. nothing left out.

It was short, I think the quote is sufficient. It talks about glass cleaners in the prior instruction about general glass cleaning and they are ok for that. By omission I assume they are not OK for the tinted rear interior glass.
