Driver Controls Heated outside mirrors (if equipped) Both mirrors are heated automatically to remove ice, mist and fog when the rear window defrost is activated. Do not remove ice from the mirrors with a scraper or attempt to readjust the mirror glass if it is frozen in place. These actions could cause damage to the glass and mirrors. Automatic dimming rear view mirror (if equipped) Your vehicle may be equipped with an inside rear view mirror with an auto-dimming feature. When the auto-dimming mirror is turned on, as indicated by an illuminated green LED to the left of the button on mirror, it will detect bright lights (glare) from behind the vehicle, and will change from the normal, high reflective state, to the darkened state to minimize glare. When the auto-dimming mirror is turned on, it will automatically return to the normal, high reflective, state whenever the vehicle is placed in R (Reverse) to ensure a clear view while backing up. Do not block the sensor located to the right of the mirror button or the sensor located on the back side of the mirror as this may impair mirror performance. ELECTRONIC COMPASS The compass heading is displayed as one of N, NE, E, SE, S, SW, W and NW in the message center display. The compass reading may be affected when you drive near large buildings, bridges, power lines and powerful broadcast antenna. Magnetic or metallic objects placed in, on or near the vehicle may also affect compass accuracy. Usually, when something affects the compass readings, the compass will correct itself after a few days of operating your vehicle in normal conditions. If the compass still appears to be inaccurate, a manual calibration may be necessary. Refer to Compass zone adjustment. 58 2005 Mercury Mariner (mrn) Owners Guide (post-2002-fmt) USA_English (fus)
