This will keep your battery from running down. Mirrors Electrochromic Day/Night Rearview Mirror With Compass This mirror automatically changes to reduce glare from headlamps behind you when set in the M (Mirror) or C/M (Compass/Mirror) positions. One photocell on the back of the mirror senses when it is becoming dark outside. Another photocell built into the mirror surface senses when headlamps are behind you. At night, when the glare is too high,the mirror will gradually darken to reduce glare (this change may take a few seconds). The mirror will return to its clear daytime state when the glare is reduced. These lamps go on when you open the doors. You can also turn them on by pressing the button to the side of the lamp. Press it again to turn them off. Trunk Lamp When you open the trunk to its full open position, a lamp will come on inside the trunk. This lamp will automatically turn off when the trunk is closed. 2-50
