Removal

WARNING: To prevent glass splinters from entering the eyes or cutting the hands, wear safety glasses and heavy gloves when cutting the glass from the vehicle. Failure to follow these instructions may result in personal injury.







1. Position the parcel shelf aside.
1 Release the backrest latch trim panels.
2 Remove the left-hand safety belt trim panel.
3 Move the parcel shelf forward.

2. Remove the C-pillar trim panel.
3. Remove the pin-type retainer and release the rear of the headliner from the roof panel.
4. Place 2 blocks of suitable material between the headliner and the roof panel to act as spacers.
5. Disconnect the 2 heated rear window glass electrical connectors.
6. Remove the 2 screws and the high mounted stoplamp.
- Disconnect the electrical connector.







7. CAUTION: Make sure the cutting blades are changed where the cutting depth changes to avoid damage to the body and trim panels.

NOTE:
- Some resistance may be encountered when cutting through the glass locating pegs in the bottom corners of the glass.
- Lubricate the urethane adhesive with water to aid the special tool when cutting the urethane adhesive.

Using the special tool, place the flat side of the knife against the rear window glass. Start at the top center and work out and down the pillars to the lower corners cutting to the given maximum depths:

1 30 mm (1.18 in)
2 25 mm (0.98 in)

Installation

CAUTION: When installing urethane-installed glass parts, the vehicle must not be driven until the urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperatures and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the rear window glass.

NOTE: For additional material guidelines, refer to the manufacturer's installation information.

1. Dry fit the rear window glass to the existing urethane adhesive on the body pinch weld. Align the glass in the opening for a uniform fit.
2. Use a non-permanent pencil to make alignment marks to aid in the installation alignment of the rear window glass.
3. Remove the rear window glass.







4. NOTE: Avoid scratching the pinch weld. For minor scratches or exposed metal on the pinch weld, see the manufacturer's recommendations.

Using an appropriate tool, trim the urethane adhesive leaving a 1-2 mm (0.04-0.08 in) base of original equipment urethane on the pinch weld.

5. If installing the original rear window glass, remove the excess urethane adhesive.
6. Clean the inside of the rear window glass with a non-alcohol based window cleaner.

7. CAUTION: Be sure to use the same brand of cure-rate products for the adhesive and primer. Do not mix different brands of urethane and primer. Refer to the Material Chart in this procedure.

NOTE: Sika uses the same black primer for the glass and pinch weld area.

If installing a new rear window glass, apply urethane glass primer according to the manufacturer's instructions. Allow at least 6 minutes to dry.







8. Cut the urethane adhesive applicator tip to the specification.

9. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that will apply the urethane with less effort and a continuous bead.

Apply urethane adhesive on top of the existing, trimmed urethane bead on the pinch weld. Make sure that all gaps in the urethane adhesive are smoothed into 1 continuous bead starting and ending at the bottom of the rear window glass near the center.







10. Install the rear window glass on the pinch weld. Align the rear window glass to the body using the alignment marks.

11. CAUTION: When installing urethane-installed glass parts, the vehicle must not be driven until the urethane has cured. Adequate cure time is specified on the drive away chart for each urethane product as the temperatures and humidity vary. Inadequate or incorrect curing can adversely affect the retention of the rear window glass.

After the urethane has cured, check the rear window glass seal for air or water leaks through the urethane adhesive bead and add urethane adhesive as necessary.

12. Connect the electrical connector, position back the high mounted stoplamp, and install the 2 screws.
13. Position the headliner, install the pin-type retainers and remove the spacers.
14. Connect the 2 heated rear window glass electrical connectors.
15. Install the C-pillar trim panel.







16. Install the parcel shelf.
1 Position the parcel shelf.
2 Install the left-hand safety belt trim panel.
3 Attach the backrest latch trim panels.
