Rear Window Glass Installation

WARNING:

Using a utility knife with bare hands can cause injury. Always wear gloves when using a utility knife.

CAUTION:

Proper installation of the glass may be difficult if sealant is cracked or the glass is pushed out by air pressure when a door is opened/closed with all the window glass closed. Keep the door glass open until the rear window glass installation is completed.

Remove sealant along the perimeter of the glass using a utility knife or scraper. (When reusing the glass)
Clean and degrease an approx. 50 mm {2.0 in} wide strip along the perimeter of the glass.
Inspect the glass for cracks. If it is cracked, chamfer it using sandpaper.
Install spacer, fasteners and pins to the glass as shown in the figure. (When reusing the glass)
