Sunvisor & Visor Clip Installation:

At the Visor Clips:
With a suitable screwdriver (most commonly a Phillips head) remove each screw holding the clip in place. Then twist the clip 90 degrees (left or right, it doesn't matter) and remove the clips.

At the Visor Hinge:
With a suitable screwdriver (most commonly a Phillips head) remove the 2 screws (per visor) at the outside mount and remove the visors.

Installing the Sunvisor Clips:
Make sure you have the correct clip for the side you are installing.

With the clip aligned vertically press it in place and then rotate it
90 degrees until the screw hole is aligned.

Install the screw and repeat for the opposite side.

Installing the Sunvisors:

Make sure you have identified the left and right visors.

The left visor will have a shorter notch at the bottom edge
(when folded down) for the rear view mirror.

The right visor has the longer notch.

Insert the mounting post into place
and install the two screws to hold the visor.

This is the most overlooked and crucial step!
Rotate the visor into place to line up with the clip and twist the visor away from the mount until it the plastic post lines up in the clip. Repeat for the opposite side and go enjoy a sunset drive without the sun in your eyes!
