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. Fold-away mirrors Pull the side mirrors in carefully when driving through a narrow space, like an automatic car wash. Automatic dimming rear view mirror 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. 50 2004 Mountaineer (mnt) Owners Guide (post-2002-fmt) USA English (fus)
