Settings MIN: The minimum setting is suggested when driving where glare conditions change often. "Min" works well for city driving at night. Cleaning Photocells Use a cotton swab and glass cleaner to clean the two photocells that make the mirror work. MAX: Maximum sensitivity is a good setting for highway driving in light traffic. The mirror starts to darken in any glare, such as headlights a long way behind your car. OFF: The mirror will stay in the day mode. Time Delay The mirror delays before switching from the night back to the day position. This delay prevents rapid changing of the mirror as you drive under lights and through traffic. Reverse Gear Day Mode The reverse mode is another important feature of the automatic mirror. .When the shift lever is placed in "R" (Reverse), the mirror shifts to the day mode. This gives you a bright image in the mirror as you back up. 107
