6.1 Power Adjustment (Main Mirror)
Use your vehicle's existing mirror control switch to adjust the angle of the main plane mirror. Ensure the mirror provides a clear view of the rear and sides of your vehicle and any attached trailer.

If your vehicle is equipped with a heated mirror function, activate it via your vehicle's controls (often integrated with the rear defroster). The heating element within the main mirror will clear frost, ice, or fog from the mirror surface.
