(1) - Rear Window Louver
(8) - Mounting brackets

Tools Required:

8mm Wrench or Socket
Painters Tape

1. Using the supplied alcohol prep pads, wipe down the outer edge of the glass as shown. Repeat using the included 3M Adhesion Promoter as well.

2. Place the louvers over the rear window, centering them left to right and lining them up with the edge of the upper weatherstripping. Once properly aligned, tape the upper corners of the louver to the car using either painters or masking tape as shown.

3. Remove the nut/washer from the plate, peel backing from tape, then slightly lift upper corners of the louver to insert the stud through the mounting hole as shown. Making sure the louver is still properly aligned, firmly press down to fully seat the adhesive tape. Repeat this step for the remaining 6 plates. You can remove the tape applied in Step 2 at this point.

4. Once all eight of the plates are installed and secured to the window, place the washers over the studs followed by the nuts and tighten with an 8mm wrench or socket. This completes the installation of your rear window louvers. 

Cleaning: To clean your rear window, simply remove the 8mm  nuts/washers and remove the louver from the vehicle.
